Plaintiff-appellant Daniel Edward Bynum brought this product liability action in district court seeking damages for injuries sustained when a M-548 cargo carrier in which he was riding fell off a bridge and crashed into the creek below. At the time of the accident, Bynum was a member of the Mississippi National Guard taking part in a seventeen-day training mission at Fort Stewart, Georgia. The district court,
I. FACTUAL AND PROCEDURAL BACKGROUND.
On July 13, 1978, Bynum, then a member of the Mississippi National Guard, was participating in a tactical road march at Fort Stewart, Georgia, as part of a training mission for the Mississippi National Guard. Bynum’s role in the march was to ride in the M-548 cargo carrier (“M-548”), a tracked United States Army vehicle, as an air gunner. While crossing a bridge, the M-548 swerved to the left and plunged into the creek bed below. As a result of the accident, Bynum sustained severe injuries, including two broken legs caused when the M-548’s turret gun rotated freely during the fall.
Thereafter, on May 4, 1982, Bynum filed the instant complaint in the District Court for the Northern District of Mississippi, alleging negligence, breach of express and implied warranties, and strict liability theories of recovery. Defendant FMC Corporation (“FMC”) 1 answered and initiated discovery, which continued for over a year until terminated by the district court on August 4, 1983. At that point, FMC moved for summary judgment on the ground that the government contractor defense barred the action. 2 In support of its motion, FMC relied primarily on the deposition testimony of Bynum’s expert witness, Dr. Malcolm Newman, and the affidavit of William H. Stites, who was the Engineering Manager of FMC’s Ordnance Division. Bynum filed no evidentiary response to the summary judgment motion.
At his deposition, 3 Newman testified that he knew of no evidence of negligence or negligent manufacture by FMC. Rather, Newman stated, the accident was most probably caused by design defects in the tracking system and the gun-locking mechanism and a failure to warn as to the proper manner in which to operate the vehicle under the conditions existing at the time of the accident. Deposition of Mal *559 colm Newman, at 66-74. In his affidavit, Stites described the function and capabilities of the M-548 as follows:
The M548 is a tracked vehicle that is used by the United States Army in a variety of ways. Its primary function is to carry ammunition both for tanks and for self-propelled artillery. The vehicle must be capable of carrying 6 tons of ammunition while traveling across all types of terrain in all types of weather. It follows behind the tanks or large cannon, such as the 155 Howitzer, mounted on tracks. The vehicle has to be air droppable, that is, capable of being dropped by parachute from airplanes; so it must have outside dimensions that allow it to fit inside the airplanes from which it would be dropped. The vehicle also must be amphibious. Not only must it be able to float when it enters the water while carrying its load of ammunition; but also it must be able to propel itself through the water.
Record at 316. Stites also explained that the specifications for the M-548 were the work product of the United States Army Tank-Automatic Command (“TACOM”), which was responsible for the designing and testing of wheeled and tracked vehicles procured by the government for military use. According to Stites, TACOM supplied FMC with a technical data package containing over 2500 sheets of detailed drawings that were to be used in the manufacture of the M-548. Under the contract, Stites stated, FMC was obligated to comply strictly with these design specifications in producing the M-548. If FMC desired to alter any particular portion of the design, the proposed modification had to be submitted to TACOM for review and testing. Any unapproved deviation from the government’s specifications would result in rejection of the vehicles by the government’s inspectors who, in accordance with the contract, worked full time at the FMC plant.
Finally, Stites stated in his affidavit that the particular vehicle that was involved in the accident had been manufactured in strict compliance with the government’s plans and specifications. The type of event that Newman described as being the most likely cause of the accident, Stites asserted, had never before occurred within the knowledge of FMC.
On February 1, 1984, Chief Judge L.T. Senter, Jr., denied FMC’s motion for summary judgment on the ground that the government contractor defense had not been recognized or adopted by any controlling precedent. The case was then transferred to Judge Biggers on April 11, 1984. At the beginning of trial, on October 1, 1984, Bynum moved in limine to prevent FMC from introducing any evidence concerning the government contractor defense. In response, FMC orally renewed its motion for summary judgment based on our intervening decision in
Hansen v. Johns-Manville Products Corp.,
(1) [The district court] has the authority to reconsider a previous ruling on a motion for summary judgment; and
(2) The vehicle in issue in the present case was manufactured in accordance with precise design specifications furnished by the United States Government, the vehicle conformed to the specifications, and the manufacturer FMC knew of no patent dangers in the vehicle that were not known to the United States Government.
Bynum v. General Motors Corp.,
Based on these stipulations, as well as on the pleadings, affidavits, memoranda, and other submissions of the parties, Judge Biggers granted summary judgment. In the published opinion accompanying the or *560 der, Judge Biggers explained that the basis of his decision was an Erie guess that Mississippi courts would apply the government contractor defense, as set forth in Hansen, if and when such a situation was presented to them. Judge Biggers found that by their stipulations the parties established that the following three prerequisites for the application of the defense were met: (1) establishment of product specifications by the government, (2) manufacture in accordance with those specifications, and (3) government knowledge equal to that of the manufacturer of the hazards. Id. at 158.
From the order granting summary judgment, Bynum appeals.
II. LEGAL BACKGROUND.
Before we examine the legal basis of the modern government contractor defense and its applicability to the ease at hand, a brief overview is in order of the defense’s historic analogues and the reasons provided by federal and state courts for the adoption of the modern defense. Toward this end, we discuss first the Feres-Stencel doctrine, which prompted the formulation of the defense. Then we examine the defenses traditionally available to manufacturers complying with design specifications supplied by the government and the deficiencies of those defenses in the current context. Finally, we review the justifications upon which recently adopted versions of the modern government contractor defense have been based.
A. The Feres-Stencel Doctrine.
In
Feres v. United States,
*561
An additional reason for the holding in
Feres
was suggested in
United States v. Brown,
The peculiar and special relationship of the soldier to his superiors, the effects of the maintenance of such suits on discipline, and the extreme results that might obtain if suits under the [Federal] Tort Claims Act were allowed for negligent orders given or negligent acts committed in the course of military duty, led the [Feres ] Court to read that Act as excluding claims of that character.
Id.
at 112,
The Supreme Court carried its
Feres
decision one step further in
Stencel Aero Engineering Corp. v. United States,
The Supreme Court began its consideration of this question by reviewing its holding in
Feres.
The Court found that its
Feres
decision was based on essentially three factors: (1) the distinctive federal character of the relationship between the government and members of the armed services, (2) the availability of “generous pensions to injured servicemen” through the Veterans’ Benefits Act, and (3) the effect that a suit by a member of the armed services against the government would have on discipline.
Id.
at 671,
*562
Since
Stencel,
it has become clear that the third factor described above is the principal justification for the
Feres-Stencel
doctrine. Most recently, for example, in
United States v. Shearer,
— U.S. -,
“It would be difficult to think of a clearer example of the type of governmental action that was intended by the Constitution to be left to the political branches directly responsible — as the Judicial Branch is not — to the electoral process. Moreover, it is difficult to conceive of an area of governmental activity in which the courts have less competence. The complex, subtle, and professional decisions as to the composition, training, equipping, and control of a military force are essentially military judgments, subject always to civilian control of the Legislative and Executive Branches. The ultimate responsibility for these decisions is appropriately vested in branches of the government which are periodically subject to electoral accountability.”
Chappell v. Wallace,
In sum, under the
Feres-Stencel
doctrine, the government is immune from both a primary suit by a member of the armed services for service-connected injuries and a third-party indemnity action arising from the same injuries. In either case, to allow such a suit would require a civilian court to second-guess military judgments or otherwise to intervene in military matters at the possible expense of military discipline and effectiveness.
See Shearer,
— U.S. at-,
B. Traditional Defenses.
Historically, the contractor who strictly complied with design specifications provided by the government had two rather effective defenses to liability for any damage arising from such specifications. Neither defense, however, has retained its vitality in the context of a modern product liability action against a manufacturer of military equipment. The defenses, as well as their deficiencies, are well documented in the literature on the subject 8 and therefore are only briefly reviewed below.
The first traditional “defense” was not actually a defense at all but a standard of conduct applicable to contractors working pursuant to either government or private contracts. Based on negligence principles, this standard provided that a contractor would not be liable for damages resulting from specifications provided by another unless those specifications were so obviously defective and dangerous that a contractor of reasonable prudence would be put on notice that the work was dangerous and likely to cause injury. Restatement (Second) of Torts § 404 comment a (1965);
see also Davis v. Henderlong Lumber Co.,
Courts are divided over whether this common law standard of liability provides protection to the contractor against a product liability action brought under strict liability principles. While some courts have extended the defense to cover strict liability claims on various public policy grounds,
9
others have held that the negligence standard of liability simply has no relevance in a strict liability action, especially one in which a design defect is alleged. In
Challoner v. Day & Zimmermann, Inc.,
The second traditional defense fares no better. In
Yearsley v. W.A. Ross Construction Co.,
Dolphin Gardens, Inc. v. United States,
The problem with applying the
Yearsley
defense in the context of the military contractor is the apparent requirement that the contractor possess an actual agency relationship with the government. While federal courts certainly have not always required such a relationship,
see, e.g., Pratt v. Hercules, Inc.,
C. Modern Government Contractor Defense.
From the foregoing, it is evident that in the last few decades, while the govern-
*565
ments immunity from suits having some connection with service-related injuries of members of the armed services has been growing more expansive and defined, the traditional defenses of military contractors have been becoming less effective in shielding them from liability for the design defects of their military products. Consequently, especially in recent years, military contractors have been threatened more frequently with liability that could not be passed on to the party ultimately responsible for the plaintiffs’ injuries — the government.
12
Military contractors, in response, have sought both judicial and legislative relief from their plight.
See generally
Souk,
Government Contracts and Tort Liability: Time for Reform,
30 Fed.B. News & J. 70 (1983). One limited form of relief that has been made available, referred to herein as the “government contractor defense,” is essentially a judicial amalgamation of the two traditional defenses,
see Johnston,
anca v. Casabianca,
Courts have relied upon numerous reasons of policy in recognizing the defense. In our view, the most important of these is that a trial between a serviceman and a military contractor in which government specifications are at issue would inevitably implicate the same concerns that underlie the Supreme Court’s
Feres
and
Stencel
decisions. Litigation involving defective designs in military products would take the identical form regardless of whether the named defendant happens to be the government or the military contractor. In either case, members of the armed services would be allowed to question military decisions and obtain relief from actions of military officials. Moreover, civilian courts would be compelled to second-guess professional military judgment concerning, at least, the proper equipping of the armed services. As noted in Part 1(A), there are few areas of government activity in which courts have less competence or that raise such significant separation of powers concerns.
In re Air Crash Disaster,
Other policy reasons suggested by the courts also give strong support to the fashioning of a government contractor defense. First, as many courts have recognized, holding military contractors liable for defective designs supplied by the government would circumvent the government’s immunity under
Feres
and
Stencel.
“[Djespite the government’s immunity, [military sup
*566
pliers] would pass the cost of accidents off to the United States through cost overrun provisions in equipment contracts, through reflecting the price of liability insurance in the contracts, or through higher prices in later equipment sales.”
McKay,
Second, military contractors are often unable through negotiation to alter the design specifications of their military products because of military efforts in certain contexts to push technology to the limits even if to do so would incur risks beyond those that would ordinarily be acceptable for consumer goods. Without the government contractor defense, military contractors would be discouraged from bidding on essential military projects. Note,
Liability of a Manufacturer, supra
note 8, at 1067-68. And, if a contractor were compelled by federal law
13
to manufacture the product, the contractor would “face the untenable position of choosing between severe penalties for failing to supply products necessary to conduct a war, and producing what the government requires but at a contract price that makes no provision for the need to insure against potential liability for design flaws in the government’s plans.”
In re “Agent Orange”Product Liability Litigation,
Third, by conditioning the application of the government contractor defense on full disclosure to the government of all known risks, military contractors would have an incentive to work closely with military authorities in the development and testing of equipment.
Tillett,
Finally, principles of fairness dictate that an innocent contractor should not be ultimately liable for a dangerous design when the responsibility properly lies elsewhere.
Brown v. Caterpillar Tractor Co.,
These policies underlying the government contractor defense, although broad in nature, have nonetheless limited its application. One version of the defense that is particularly well tailored to the policies that it serves was formulated by the Ninth Circuit in McKay v. Rockwell International Corporation, a case arising under the Death on the High Seas Act, 46 U.S.C. §§ 761-767. To invoke the government contractor defense under the McKay test, the military contractor must demonstrate:
(1) [that] the United States is immune from liability under Feres and Stencel,
(2) ... that the United States established, or approved, reasonably precise specifications for the allegedly defective military equipment,
(3) [that] the equipment conformed to those specifications, and
(4) [that] the supplier warned the United States about the patent errors in the government’s specifications or about dangers involved in the use of the equipment that were known to the supplier but not to the United States.
McKay,
Although the
McKay
test has been widely adopted,
see, e.g., In re Air Crash Disas
*567

III. ANALYSIS.
Bynum on appeal challenges in two general respects the district court’s opinion and order granting summary judgment to FMC. First, Bynum argues that there is nothing in Mississippi caselaw to suggest that Mississippi courts would adopt the government contractor defense. Thus, Bynum asserts, the district court erred in applying it as a matter of Mississippi law. Second, Bynum contends that, even if the government contractor defense were recognized, the particular version adopted by the district court would provide more protection to the military contractor than is required by the legitimate policies of the defense. Because we find that the interests that justify the creation of the government contractor defense also compel its application as a matter of federal common law, we do not reach the state law question. 15 Further, for the reasons outlined above and discussed more fully below, we adopt the McKay test, at least insofar as it applies to the circumstances of the instant case, and affirm the summary judgment.
A. Federal Common Law.
There is no question that jurisdiction in this product liability suit is based solely on diversity of citizenship and therefore state law generally governs the resolution of the controversy.
See Jackson v. Johns-Manville Sales Corp.,
Under the applicable caselaw, we must apply a two-tier analysis in determining whether federal common law provides a government contractor defense under the circumstances of this case. First, as ' a threshold matter, we must consider whether the question at bar substantially bears upon “uniquely federal” interests.
Texas Industries, Inc. v. Radcliff Materials, Inc.,
1. Uniquely Federal Interests.
In Texas Industries, Inc. v. Radcliff Materials, suyra, the Supreme Court described the kinds of cases that raise issues of uniquely federal concern:
[AJbsent some congressional authorization to formulate substantive rules of decision, federal common law exists only in such narrow areas as those concerned with the rights and obligations of the United States, interstate and international disputes implicating the conflicting rights of States or our relations with foreign nations, and admiralty cases. In these instances, our federal system does not permit the controversy to be resolved under state law, either because the authority and duties of the United States as sovereign are intimately involved or because the interstate or international nature of the controversy makes it inappropriate for state law to control.
Id.
The most obvious example in which the authority and duties of the United States as sovereign would be intimately involved is a controversy whose outcome will have an immediate effect on the federal treasury.
Clearfield Trust Co. v. United States,
We have already seen that the primary justification for the government contractor defense is the same as that for the
Feres-Stencel
doctrine: members of the armed services should not be able to challenge the decisions and actions of military authorities by thrusting the judiciary into the role of adjudicating what are essentially military matters. The plenary control of military judgments by the legislative and executive branches of the federal government, however, is more than a separation of powers concern. The composition, training, equipping, and management of our military forces is a matter exclusively within the rights and duties of the federal government and, as a result, any interference with the federal authority over national defense and military affairs implicates uniquely federal interests of the most basic sort. This was one of the lessons of
In re Tarble,
80 U.S. (13 Wall) 397,
Now, among the powers assigned to the National government, is the power “to raise and support armies,” and the power “to provide for the government and regulation of the land and naval forces.” The execution of these powers falls within the line of its duties; and its control over the subject is plenary and exclusive. It can determine, without question from any State authority, how the armies shall be raised, whether by voluntary enlistment or forced draft, the age at which the solider shall be received, and the period for which he shall be taken, the compensation he shall be allowed, and the service to which he shall be assigned. And it can provide the rules for the government and regulation of the forces after they are raised, define what shall constitute military offenses, and prescribe their punishment. No interference with the execution of this power of the National government in the formation, organization, and government of its armies by any State officials could be permitted without greatly impairing the efficiency, if it did not utterly destroy, this branch of the public service.
Id.
at 408,
The application of these principles to a soldier’s product liability litigation involving the merits of military design specifications supplied by the government is clear. There can be no question that the design of military equipment is, at bottom, a military decision. Often dangerous designs must be used in the military context to meet the exigencies of our national defense, and even military equipment that is relatively safe for every day use may have to be operated on occasion under dangerous conditions or in a manner creating a high risk of harm. In this respect, we think that the District Court for the Eastern District of New York was correct in observing:
The purpose of a government contract defense ... is to permit the government to wage war in whatever manner the government deems advisable, and to do so with the support of suppliers of military weapons. Considerations of cost, time of production, risks to participants, risks to third parties, and any other factors that might weigh on the decisions of whether, when, and how to use a particular weapon are uniquely questions for the military and should be exempt from review by civilian courts.
In re “Agent Orange” Product Liability Litigation,
We find the present situation to be not unlike that of
Banco Nacional v. Sabbatino, supra.
At issue in
Banco Nacional
was the legal basis and scope of the “act of state” doctrine, which precludes judicial inquiry into the public acts of a recognized foreign sovereign power committed within its own territory. The Supreme Court held that, because of the essential political nature of foreign expropriation and its significance in international affairs, the basic relations between the judicial and political branches of government required that the judiciary not pass on the validity of the expropriations.
Id.
Whatever considerations are thought to predominate, it is plain that the problems involved are uniquely federal in nature. If federal authority, in this instance this Court, orders the field of judicial competence in this area for the federal courts, and the state courts are left free to formulate their own rules, the purposes behind the doctrine could be as effectively undermined as if there had been no federal pronouncement on the subject.
Id.
at 424,
Similarly, the government contractor defense is rooted in separation of powers concerns that would be frustrated by the application of state law and policies. Like the act of state doctrine, the government contractor defense embodies “a basic choice regarding the competence and function of the Judiciary and the National Executive” and “should not be left to divergent and parochial state interpretations.”
Id.
at 425,
Thus, we find that a suit by a serviceman against a military contractor in which at issue are government design specifications for military equipment does give rise to uniquely federal interests sufficient to warrant the imposition of federal law. Such a suit involves the second-guessing of military decisions by civilian courts and threatens to impair essential military discipline. The states, as well as the judiciary,
*571
are “ill-equipped to determine the impact upon military effectiveness that any particular intrusion upon military authority may have,”
see Chappell v. Wallace,
2. Conflict with State Policy.
The overriding federal interest at stake here concerns the preservation of exclusive control over military matters in the legislative and executive branches of the federal government. Thus, if state laws permitting or requiring judicial intervention into such matters were applied, the federal interest would be entirely frustrated. This conflict, by itself, suffices to preclude adoption of state law as the federal rule.
Sanders,
We nonetheless also examine the effect of a federal government contractor defense on important and legitimate state interests. In this regard, we find most telling the fact that a clear majority of courts that have considered the availability of the government contractor defense under applicable state law have decided to adopt the defense.
See, e.g., Tillett v. J.I. Case Co.,
Nor would the traditional policies that support strict liability be substantially advanced by application of the doctrine in a case where the military contractor merely followed the design specifications of the government. The parties draw our attention to four principal reasons for imposing strict liability: enterprise liability, market deterrence, compensation, and implied representation of safety.
See also McKay,
According to enterprise liability principles, strict liability should be imposed on producers in order to force them to incorporate accident costs into the price of their products. The theory is that the increased prices will then discourage consumers from purchasing risky products and thereby lower total accident costs to society. Further, imposing the costs of accidents generally on manufacturers and consumers allows the costs of product-caused injuries to be spread over a class of users. In the context of the government contractor defense, however, neither of these goals would be met. First, as the
McKay
court noted, the demand for military equipment, unlike consumer goods, is relatively inelastic. Decisions to purchase military equipment are usually made far in advance and are often based on considerations of military and political strategy as well as the government’s assessment of the risks and the benefits involved in the use of the equipment. “Meeting adequately the needs of national defense, not accident costs, is the ultimate standard by which purchases of military equipment must be measured.”
McKay,
Strict liability also often functions to deter manufacturers from marketing unreasonably dangerous products. When military equipment is at issue, though, there is a strong government interest in encouraging the military contractor to agree to manufacture potentially dangerous products for the government and to comply strictly with government design specifications. Nor do these policies deprive the user of all protection from unintended design defects. As is illustrated by the record in this case,
20
the government “has both the ability to recognize safety problems in military equipment and to negotiate with the suppliers to remedy those problems.”
McKay,
The third justification, compensation, also does not compel the imposition of strict liability for defective designs supplied by the government. As the Supreme Court noted in
Stencel,
“the Veterans’ Benefits Act establishes, as a substitute for tort liability, a statutory no fault compens'ation scheme which provides generous pension to injured servicemen.”
Stencel,
Finally, strict liability usually serves to vindicate the reasonable expectations of the consumer that a product purchased by a seller will not be unreasonably dangerous. As the
McKay
court observed, however, “[members of the armed services] recognize when they join the armed forces that they may be exposed to grave risks of danger.”
McKay,
3. Fifth Circuit Precedent.
Our holding today, adopting the government contractor defense as a matter of federal common law, is not inconsistent with either
Challoner v. Day & Zimmermann, Inc., supra,
or
Hansen v. Johns
*573
Manville Products Corp., supra.
In
Challoner,
a serviceman sustained injuries when a howitzer round prematurely exploded during combat with North Vietnamese. He subsequently brought a strict liability tort action against the manufacturer in federal district court. The manufacturer responded that it was immune from liability because the design of the shell was within the exclusive control of the government.
Challoner
is distinguishable on several points. First, we considered in that case only the application of federal common law to the entire action, not the creation of merely a federal defense.
Cf. Jackson v. Johns-Manville Sales Corp.,
Hansen v. Johns-Manville Products Corp.
involved a diversity suit brought by an employee of a shipyard against the manufacturer of asbestos for injuries received allegedly as a result of his work with asbestos products. The manufacturer in defense claimed that it produced the asbestos in conformity with government specifications and thus under Texas law should be immune from liability. We refused to recognize the government contractor defense in that case in part because Texas courts had not indicated that they would adopt the defense under similar circumstances.
Hansen,
like
Challoner,
is distinguishable on the ground that we also were not presented with the federal common law question. Both parties concerned themselves solely with the application of Texas law and policies. Furthermore, the plaintiff in
Hansen
was not a member of the armed services. Thus, the federal interest in military discipline was not implicated. That this factor is a vital component in the analysis cannot be questioned in view of the Supreme Court’s recent refusal to apply the
Feres-Stencel
doctrine to cases involving military-related injuries of civilians.
See Lockheed Aircraft Corp. v. United States,
*574 4. Conclusion.
In sum, we hold that uniquely federal interests are implicated in actions brought by members of the armed services against military contractors where at issue are design specifications supplied by the government for the manufacture of military equipment. The federal interests, rooted in notions of the limits of the judicial function and in separation of powers concerns, require the creation of a federal common law government contractor defense. We now turn to address some of the specifics of that defense and its applicability in the case at hand.
B. Government Contractor Defense Applied.
At least with respect to the circumstances of this case, we think that the
McKay
formulation of the government contractor defense, set forth in Part II, substantially reflects the pertinent federal interests. To establish the government contractor defense, a military contractor must first demonstrate that the government is immune from liability under the
Feres-Stencel
doctrine. This requirement ensures that the federal interests in avoiding judicial and state intrusion upon military authority are present and warrant the imposition of federal common law. Second, the military contractor must prove that the government established reasonably precise specifications for the allegedly defective military equipment and that the equipment conformed to those specifications. This element makes clear that federal law provides no defense to the military contractor that mismanufactures military equipment or that is itself ultimately responsible for the design defect.
23
Finally, it must be shown that the military contractor warned the government about errors in the government specifications or dangers involved in the use of the equipment that were known to the contractor but not to the government. The primary purpose of this requirement is to enable the government to make determinations as to the design and use of military equipment based on all readily available information.
See McKay,
Bynum asserts three objections to our adoption of the
McKay
test. First, Bynum contends that the government contractor defense should be limited to those circumstances in which a military contractor was required by law to manufacture the product and had no ability to refuse to enter into the contract.
Cf.
Note,
Strict Liability Suits, supra
note 10, at 1048-51 (advocating adoption of similar type of compulsion prerequisite). Such a requirement, however, would bear no connection with the uniquely federal interests that the government contractor defense is designed to protect. Moreover, a requirement of compulsion of this sort would discourage military contractors from bidding on government projects or, alternatively, give the contractors incentive to pressure the military to purchase safer equipment. Either result would be contrary to sound public policy, which, as we have seen, requires that contractors be encouraged to
*575
enter into contracts with the government for the production of military hardware and to adhere fully to specifications furnished by the government. While it is reasonable to expect a military contractor to apprise the government of any risks relating to the equipment of which it has knowledge, the contractor, like the judiciary, should not be thrust into the position of second-guessing military decisions. As noted above, it is the needs of national defense, not accident costs, that must be the ultimate standard by which the purchase of military equipment is measured.
McKay,
Second, Bynum argues that the government contractor defense should only be available when the product at issue incorporates the newest technology or when the formulation of the designs requires “special military expertise.”
26
Again, we decline to limit the scope of the defense in the manner that Bynum suggests. That a decision requires consideration of no specialized knowledge does not preclude it from being, in the final analysis, a military judgment. Military authorities in deciding whether, when, and how to use military equipment must balance considerations of cost, time of production, risks of harm, the needs of our national defense, and other factors that touch upon such decisions. It is the balancing of these factors, not merely the nature of the information upon which that balance is predicated, that the government contractor defense seeks to exempt from challenge by servicemen in civilian courts.
See In re “Agent Orange” Product Liability Litigation,
Lastly, Bynum argues that, in order to assert the government contractor defense, the military contractor should have to demonstrate that it warned the government about all defects or dangers of which the contractor knew or should have known. It is suggested that such a duty would increase the information flow between the military contractor and the government and allow the government to make better informed military determinations.
28
While
*576
we do not wish to understate the importance of this goal, we think that the “known or should have known” standard is not warranted here. Such a duty would compel the military contractor to reevaluate the design specifications furnished by the government and to engage in testing not required under the government contract. Such reevaluations and additional testing would mean delay and an increase in defense costs not contemplated by the military authorities. Furthermore, as we noted in our discussion of market deterrence, the military has the ability to recognize safety problems or at least negotiate with the contractors for further testing, especially with respect to those design specifications that it generates itself.
See McKay,
It therefore remains for us to determine whether the district court erred in granting FMC’s motion for summary judgment. Under rule 56(c) of the Federal Rules of Civil Procedure, summary judgment is proper when, viewed in the light most favorable to the non-moving party, “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact.” Fed.R.Civ.P. 56(c);
see also Galindo v. Precision American Corp.,
The first element of the McKay test, that the Feres-Stencel doctrine ap *577 plies, is not here in dispute. Both parties agree that Bynum was a member of the armed services at the time of the accident 30 and that the accident itself was service-related. Record at 350-51. Similarly, the second and third elements of the test have been established through the express stipulations of the parties. According to these stipulations, the M-548 was manufactured in accordance with precise design specifications furnished by the government and conformed to those specifications.
With respect to the fourth element of the test, however, the stipulations of the parties fall short. Although the parties have established through their stipulations that FMC knew of no patent dangers in the vehicle that were not known to the government, FMC can successfully assert the defense only if it knew of no dangers in the vehicle, either patent or latent, about which the government did not know. 31 Nonetheless, we think that the affidavit of William Stites, the Engineering Manager of FMC’s Ordnance Division, taken together with the stipulations, meets FMC’s burden of demonstrating the absence of any genuine issue of material fact. In his affidavit, Stites stated that he had been employed by FMC since it agreed to manufacture the M-548 cargo carrier for the Army and that the M-548 was part of his responsibility. Stites further stated that he had read the deposition of Dr. Malcolm Newman, Bynum’s expert witness, which contained Newman’s description of how the accident probably occurred. In Stites’ opinion, that type of event “has never occurred within the knowledge of FMC.” Moreover, according to Stites, “FMC has never received from TACOM or any other source reports that the type of event has occurred with any M-548 or M113 family member manufactured by FMC.” Record at 321.
Bynum did not introduce affidavits or any other evidence to counter FMC’s prima facie proof that it had no knowledge of dangers involved respecting the M-548 that were not known to the government. Indeed, Bynum even on appeal does not allege that FMC possessed such knowledge. 32 We, therefore, conclude that Bynum did not discharge his summary judgment burden and that FMC is entitled to judgment as a matter of law.
IV. CONCLUSION.
For the aforementioned reasons, we hold that, under the circumstances of this case, federal common law provides a basis for the fashioning of a government contractor *578 defense. Because FMC has established all four elements of this defense, with no genuine issue of material fact remaining, the summary judgment in favor of FMC is affirmed.
AFFIRMED.
Notes
. General Motors Corporation ("GM”) was also an original defendant in this action. GM was granted summary judgment on June 27, 1983, and that order has not been appealed.
. FMC also sought summary judgment on a variety of other grounds, none of which are relevant here. The district court granted summary judgment to FMC with respect to Bynum’s warranty claims. Bynum does not challenge that order on appeal.
. Newman's deposition has been made a part of the record on appeal by stipulation of the parties.
. See infra Part III(A)(3).
. See 28 U.S.C. § 1346(b) (providing that the law of the place where the actionable act or omission occurred applies in actions brought under the FTCA).
. Bynum argues that in
Stencel
the Supreme Court also suggested that a member of the armed services could sue the manufacturer for defects in government designs of military equip-770 F.2d — 15 ment. In making this argument, Bynum refers specifically to footnote 8 of that opinion, which reads: "Since the first Circuit case to hold [indemnity] actions barred by
Feres
was decided in
*562
1964 ... petitioner no doubt had sufficient notice so as to take this risk into account in negotiating its contract for the emergency eject system at issue here."

Whitaker,
the manufacturer of grenades, Day & Zimmermann, Inc., operated a government-owned plant and used material supplied by the government. Assembly of the grenades rigidly followed government specifications. Further, the contract itself called for indemnification by the government for losses arising from performance under the contract. Nonetheless, the panel, citing
Powell v. United States Cartridge Co.,
. This dilemma of the military contractor is made all the more severe by (1) the contractor’s frequent inability to deviate from the specifications supplied by the government in the manufacture of a product and (2) the excessive risks that are frequently inherent in the use of essential military equipment. See generally Polinsky, Products Liability and the United States Government Contractor, 14 Pub.Cont.LJ. 313 (1984); Tobak, A Case of Mistaken Liability: The Government Contractor’s Liability for Injuries Incurred by Members of the Armed Forces, 13 Pub.Cont.L.J. 74 (1982).

In re “Agent Orange” Product Liability Litigation,
In 1984, the
Agent Orange
court modified its version of the government contractor defense.
See In re “Agent Orange"Product Liability Litigation,
. The application of the government contractor defense as a matter of federal common law was urged by FMC and was fully briefed by both parties.
.
But see Brown v. Caterpillar Tractor Co.,
. We note, however, that the Third Circuit has apparently adopted an opposite view. In
Brown v. Caterpillar Tractor Co., supra,
the court held that federal interests do not justify the creation of a government contractor defense as a matter of federal law. In so holding, the court, applying the factors outlined by the Supreme Court in
Feres
and
Stencel,
stated that “such suits generally do not necessitate the second-guessing of military decisions."
. In
In re "Agent Orange”Product Liability Litigation,
Speculative federal interests in the obligations of war contractors are numerous. War contractors might be expected to increase the price of war materials to correspond to any extension in their potential liability. Such adjustments might have a significant effect on the federal treasury. If potential liability increased dramatically, future war contractors might attach conditions to the use of their products, or balk at supplying the military with any products whatsoever. Thus, the government’s military capacities might be affected by this litigation.
Id. at 747 n. 5. See also Note, Tort Remedies for Servicemen Injured by Military Equipment: A Case for Federal Common Law, 55 N.Y.U.L.Rev. 601, 617-18 (1980).
. There is a significant federal interest in uniformity for its own sake here as well. If a contractor’s liability for the accident costs of its military equipment depends upon which state law is applied, the contractors that are less likely to be subject to such liability would have an unfair competitive advantage in the bidding process. Consequently, it may be more difficult to identify and award military contracts to the most efficient contractor.
. As recounted in Part I, the M-548 cargo carrier at issue in this case was designed by TACOM, a division of the Department of the Army. According to the uncontroverted affidavit of William H. Stites, submitted in conjunction with FMC’s motion for summary judgment, TACOM has a staff of over 5500 personnel, both civilian and military, who are engaged in the design and testing of wheeled and tracked vehicles procured for military use. TACOM personnel include power plant engineers, power train engineers, suspension engineers, material engineers (ballistics experts, etc.), welding engineers, quality engineers, packing engineers, and other specialists. It is TACOM’s reported function to make the military decisions and the engineering and design decisions necessary to insure that the M-548 as well as other military vehicles are able to perform the military missions for which they are conceived.

Challoner
can also be construed as a mismanufacture case since the most likely cause of the explosion was the existence of a cavitation in the explosive material poured into the artillery round.
. We pretermit the question whether asbestos can be considered "military equipment.”
. Courts and commentators disagree over the extent to which the government must participate in generating the design specifications of military equipment before the government contractor defense would be applicable.
See, e.g., In re Air Crash Disaster, 169
F.2d at 121;
McKay,
. Because the policies underlying the government contractor defense apply equally well regardless of whether the action is predicated on an allegedly dangerous defect in the design of the product or a failure to warn, the government contractor defense functions as an affirmative defense against both claims of tort liability. See McKay, supra (defense applies in cases brought under Restatement (Second) of Torts § 402A); Note, Liability of a Manufacturer, supra note 8, at 1063-64.
. Although we hold that complusion
to contract
with the government is not a prerequisite to raising the government contractor defense, we express no opinion as to whether a precondition of the defense should be that the contractor was compelled
under the contract
to follow the government’s design specifications. We note that this question is another one that has been the subject of considerable debate among courts and commentators.
See, e.g., Brown v. Caterpillar Tractor Co.,
. What Bynum means by the phrase “special military expertise” is not altogether clear. We assume that the term refers to expert knowledge of military affairs, strategy, or performance requirements.
. Again, we express no opinion on issues not directly raised by the instant case, such as whether military expertise might be needed to trigger the defense when the government merely approves a design furnished by the contractor.
Cf. Shaw v. Grumman Aerospace Corp.,
. At one point, Bynum also contends that the
McKay
court itself intended to adopt a "known or should have known” standard, at least with respect to open and obvious design defects. In support, Bynum refers to the Ninth Circuit’s statement establishing the fourth element of the defense: "the supplier [must have] warned the United States about patent errors in the government's specifications or about dangers involved in the use of the equipment that were known to the supplier but not to the United States."
McKay,
. We recognize that in
In re “Agent Orange" Product Liability Litigation,
. The National Guard, of course, is a component of the armed services of the United States,
see
10 U.S.C. §§ 331
et seq.-,
32 U.S.C. §§ 101
et seq.; Gilligan v. Morgan,
. We are perhaps being overly cautious on this point. Bynum conceded during oral argument that the parties intended to stipulate that the facts of the instant case satisfied all the elements of the test for the application of the government contractor defense set out in
In re “Agent Orange” Product Liability Litigation,
. At oral argument, Bynum stated that he was unprepared for the renewed summary judgment contest because of his reliance upon the initial ruling of the court denying FMC’s summary judgment motion on the ground that the government contractor defense was not available as a matter of law. Bynum, however, stipulated on the record that the district court had the power to reconsider the original summary judgment ruling. Further, Bynum failed to request additional time to obtain counter affidavits. Finally, the court reconsidered the summary judgment motion on the day of trial, some time after discovery had been ordered terminated and when all the evidence in the case should have been relatively accessible for use in demonstrating a genuine issue of material fact. Under these circumstances, Bynum is not entitled to relief from his summary judgment burden.
