Cоnner Bros. Construction Company, Inc., a construction contractor doing work for the Army Corps of Engineers, sought delay damages after it was denied access to its construction site on a military base for 41 days following the terrorist attacks of September 11, 2001. The Armed Services Board of Contract Appeals denied Conner’s claim on the ground that the sovereign acts doctrine shielded the Army from liability. We agree with the Board that the order excluding Conner from the base was a sovereign act that precludes recovery of damages for the delay that resulted from that act.
I
On April 21, 2000, Conner contracted with the Corps of Engineers to construct an Army Ranger regimental headquarters facility within the 75th Ranger regimental compound at Fort Benning, Georgia. The Ranger compound is a segregated area within Fort Benning that is under the operational control of the Ranger regimental commander. The contract, which was for the construction of four buildings at two sites within the compound, was administered by a Corps of Engineers project manager.
In response to the terrorist attacks against the United States on September 11, 2001, Fort Benning was placed at force protection condition Delta and shut down to everyone except essential personnel. General (then Colonel) Joseph Votel, the commander of the 75th Ranger regiment, also restricted access to the Ranger compound to mission-essentiаl personnel and ordered his staff to direct Conner to stop work and vacate the compound immediately. Conner’s workforce left the compound by 2:00 p.m. on September 11, 2001, at which point its contract work was roughly 70-75% complete. On September 17, 2001, Fort Benning lowered its force protection condition, allowing contractors and other personnel to return to the base. However, *1371 the Ranger compound continued to operate under condition Delta and remained subject to General Votel’s order restricting access to mission-essential personnel, and Conner continued to be excluded from its worksites within the compound.
In the immediate aftermath of the terrorist attacks, the Rangеrs prepared for deployment to Afghanistan. They executed a “protracted low-level deployment” whereby they departed in small groups so that their movements would not attract notice. During that period, the Rangers occupied one of the partially constructed buildings on Conner’s worksite. General Votel testified that he decided to shut down Conner’s construction activities in order to maintain operational security by preventing information leaks while the Rangers prepared to deploy. He explained that because Conner’s work was the “biggest thing happening on the installation,” Conner’s activities put its employees and subcontractors in a unique position to observe sensitive deployment activities.
Conner was excluded from the compound until September 27, 2001, when it was allowed to return to one of its work-sites. It was permitted access to its other site on October 15, 2001, and it resumed work there on October 21, 2001. Conner subsequently sought additional time to complete the project and $137,744 in delay damages attributable to 35 of the 41 days during which it was shut down^ — 'that is, for the period between September 17, 2001, when other contractors were permitted back on the compound, and October 21, 2001, when Conner returned to work. The contracting officer granted Conner the requested additional time to complete the project but denied the monetary claim. Conner appealed that decision to the Bоard.
After conducting a three-day hearing, the Board denied Conner’s appeal. As an affirmative defense, the Corps of Engineers asserted that the exclusion of Conner from the construction site constituted a sovereign act that precluded Conner from recovering damages for the delay. Conner argued that it was the sole target of the shutdown order, as it was the only contractor ordered to leave the compound. For that reason, Conner argued, the shutdown order was not a “public and general” act, and the government therefore could not invoke the “sovereign acts doctrine” as a defense to liability for breach of contract. The Board, however, found that the exclusion оrder was a sovereign act because it stemmed from the government’s war-making powers, was merely incidental to the accomplishment of a broader governmental objective relating to national security, and was not directed principally at Conner’s contract rights. The Board also rejected Conner’s arguments that it was entitled to relief under the contract’s “Changes” and “Suspension of Work” clauses. Conner now appeals to this court.

The sovereign acts doctrine provides that “the United States when sued as a contractor cannot be held liable for an obstruction to the performance of the particular contract resulting from its public and general acts as a sovereign.”
Horowitz v. United States,
The doctrine is rooted in three early Court of Claims cases. In
Deming v. United States,
In
Jones v. United States,
Finally, in
Wilson v. United States,
The Supreme Court addressed the sovereign acts doctrine for the first time in
Horowitz v. United States,
The two characters which the government possesses as a contractor and as a sovereign cannot be thus fused; nor can the United States while sued in the one character be made liable in damages for their acts done in the other. Whatever acts the government may do, be they legislative or executive, so long as they *1373 be public and general, cannot be deemed specially to alter, modify, obstruct or violate the particular contracts into which it enters with private persons.
Id.,
quoting
Jones,
In addition to requiring that the governmental act be “public and general,” the Court in Horowitz explained that private contractors who deal with the United States should not be treated any more favorably than if they had contracted with a private party. Thus, just as private contractors would not recover in the event of an intervening sovereign act that disrupted contract expectations, the Court stated that the same principle would apply to those contracting with the government. The Court wrote:
In this court the United States appear simply as contractors; and they are to be held liable only within the same limits that any other defendant would be in any other court. Though their sovereign acts performed for the general good may work injury to some private contractors, such parties gain nothing by having the United States as their defendants.
Id.; see also Jones,
In
United States v. Winstar Corp.,
The Court in
Winstar
rejected the government’s argument that the legislation constituted a sovereign act that provided a defense against claims of contract breach. The principal opinion, authored by Justice Souter, explained that in order to place the government on an equal footing with other contractors, “some line has to be drawn” between situations in which the government’s act is “relatively free of Government self-interest,” and those in which the action is “tainted by a governmental object of self-relief.”
Winstar,
Although thе portion of the principal opinion addressed to the sovereign acts doctrine had the support of only four (and as to some portions, only three) justices, this court has treated that opinion as setting forth the core principles underlying the sovereign acts doctrine.
See Carabetta Enters., Inc. v. United States,
In cases following
Winstar,
we have reiterated that the sovereign acts defense is unavailable where the governmental action is specifically directed at nullifying contract rights.
See, e.g., City Line Joint Venture v. United States,
In addition, when considering whether the alleged sovereign act is exclusively directed to aborting performance of government contracts, courts addressing the sovereign acts doctrine have looked to the extent to which the governmental action was directed to relieving the government of its contractual obligations. As Justice Souter stated in
Winstar,
“The greater the Government’s self-interest, ... the more suspect becomes the claim that its private contracting partners ought to bear the financial burden of the Government’s own improvidence....”
Winstar,
Another factor relevant to the “public and general” inquiry is whether the governmental action applies exclusively to the contractor or more broadly to include other parties not in a contractual relationship with the government. In the
Yankee Atomic
case, an electric utility that purchased uranium enrichment services from the government brought suit to recover costs it incurred pursuant to the Energy Policy Act of 1992, which required domestic utilities to pay a pro rata share of costs associated with decontaminating and decommissioning former enrichment facilities. In concluding that the legislation constituted a sovereign act, we emphasized that “the special assessment does not reach only those utility compаnies that previously contracted with the Government; it also reaches those utilities that purchased the services through the secondary market but had
no
contracts with the Government.”
In light of these principles, we sustain the Board’s decision that the exclusion order that temporarily shut down Conner’s performance was a sovereign act and that the government is therefore not liable for delay damages under its contract with Conner. As we explain in detail below, the exclusion order was not directed at relieving the government of its contractual obligations; to the contrary, any effect on Conner was incidental to a broader governmental objective relating to national security.
Ill
Conner’s primary contention on appeal is that General Votel’s exclusion order cannot be a public and general act, because the order was specifically directed at Conner’s performance of its contract. This argument is predicated on Conner’s assertion that General Votel issued two separate directives: one restricting the Ranger compound to mission-essential personnel, and the other specifically excluding Conner from the comрound. In fact, however, the two orders are not as segregable as Conner suggests. Instead, the decision to exclude Conner was simply an extension of the broader access restrictions implemented to respond to the emergency created by the terrorist attacks.
The Board found, and Conner does not dispute, that the restriction of the Ranger compound to mission-essential personnel and the refusal to admit Conner both served the same governmental objective: maintaining operational security as the Rangers prepared to deploy after the attacks of September 11, 2001. General Vo- *1376 tel and his deputy commander testified to their concern that Conner’s operation wаs a large-scale project, that Conner’s workers were constantly moving about the compound, and that the workers were well positioned to observe Ranger staging activities. The Rangers also needed one of the partially completed facilities to prepare for their post-September 11 mission. Based on the evidence before it, the Board found that Conner was barred from returning to the compound because of General Votel’s determination that Conner’s activities on the compound presented risks and impediments to the accomplishment of an important policy objective that was unrelated to the parties’ obligations under the contract. The Board therefore concluded that Conner’s exclusion from the compound was not directed at the contract, but was just a specific application of the general exclusion order.
Conner contends that General Votel’s order was targeted at Conner’s contract rights precisely because his order was predicated on concerns about Conner’s presence in the compound. In so arguing, Conner seemingly takes issue with the Board’s finding that in attempting to secure the Ranger compound and provide a facility for the Rangers to prepare for deployment, General Votel had to make particularized judgments as to which activities potentially interfered with that objective. Contrary tо Conner’s suggestion, the fact that the government made case-specific determinations as to who was nonessential and whose presence interfered with the Rangers’ operations in the compound does not convert an otherwise public and general act into a nongeneral one. Nor does the fact that General Votel specifically instructed his subordinates to order Conner to vacate the compound on September 11, 2001, bolster Conner’s assertion that its exclusion constituted an action distinct from the general exclusion order.
Conner next makes the related claim that because it was the only contractor barred from returning to work on the compound, while certain оther contractors were granted access, the exclusion order must necessarily be regarded as directed at Conner’s contract rights. That argument suffers from several flaws. To begin with, the exclusion order was not limited to Conner’s activities. The Board found that under the access restrictions, “ordinary civilians, journalists, Department of the Army civilians, and contractors not concerned with the Rangers would have been denied access to the compound.” Thus, by analogy to
Yankee Atomic,
the access restrictions reached not only parties having contracts with the government, but also parties with no government contracts at all, including the public at large.
See Yankee Atomic,
More generally, the public and general nature of an aсtion does not turn on the number of contracts it actually obstructed. While the legislation at issue in
Winstar
affected financial institutions generally, that did not prevent the Supreme Court from rejecting the sovereign acts defense, because the legislation specifically discharged the government’s contractual obligations to the institutions that had agreed to acquire failing thrifts. Conversely, governmental actions affecting a single contractor can be shielded by the sovereign acts doctrine as long as the effect on the contractor’s contract rights is incidental to a broader governmental objective. For example, in
Casitas Municipal Water District v. United States,
The Board correctly concluded that this case is a far cry from the “change of heart” cases in whiсh the government unilaterally terminated a single contract after deciding that performance would be unwise.
See Everett Plywood Corp. v. United States,
The fact that other contractors were permitted back onto the Ranger compound after September 17, 2001, also does not support Conner’s contention that its exclusion resulted from a governmental act aimed at its contract rights. The Board noted that dining facility and custodial services contractors, a Coca-Cola vendor, and cable television personnel were all allowed on the compound while Conner was denied access. The Board found, however, that although Conner was “treated differently from non-construction contractors,” those other contractors were not situated similarly to Conner.
See Gothwaite v. United States,
The government acknowledges that the Coca-Cola vendor and the cable personnel who were admitted to the compound were not mission-essential. General Votel admitted that their presence in the compound during the restricted access period was inappropriate; in fact, he explained, their presence contravened his orders. But the Board found that the Coca-Cola and cable personnel, like the dining and custodial contractors, were “qualitatively different” from Conner. Conner and its subcontractors constituted a massive pres *1378 ence on the compound, moved around extensively, could view the areas of the compound where the Rangers were preparing to deploy, and could not feasibly be escorted. In that regard, the Coca-Cola and cable television personnel were not situated similarly to Conner. Moreover, and more importantly, the admission of the Cоca-Cola and cable television personnel was a mistake, in that it violated General Votel’s exclusion order. The fact that his order was disobeyed in those instances does not affect the general nature of the exclusion order or show that the government’s action targeted Conner’s contract rights. Based on the Board’s factual findings we sustain the Board’s legal conclusion that the admission of non-construction contractors in the period following September 17, 2001, did not bar the application of the sovereign acts defense.
The Board’s conclusion that General Vo-téis exclusion order was not directed at Conner’s contract rights is further supported by the fact that the government gained no economic advantage by refusing to admit Conner to the Ranger compound.
See Casitas,
Granting Conner delay damages would also undercut one of the principal rationales of the sovereign acts doctrine: that contractors dealing with the government should not receive more favorable treatment than they would if contracting with a private party. If Conner had contracted with a private company to construct a building immediately outside Fort Ben-ning, and the Army had temporarily excluded Conner from its worksite after the attacks of September 11 in order to set up a security perimeter around the base and to facilitate troop deployments, Conner would not have been able to shift the costs resulting from the work stoppage to its private contracting partner (absent a specific clause in the contract so providing). That being so, it would be anomalous to grant Conner monetary damages in a parallel situation in which the only difference is that the government, rather than a private party, was Conner’s contracting partner.
In short, General Votel’s order excluding Conner from its worksite fits comfortably within the category of actions that we have consistently upheld as sovereign acts. In fact, the circumstances of this case closely parallel those in
Wilson,
where the government contractor was refused entry intо Washington, D.C., during the Civil War pursuant to an exclusion order issued by the city’s military governor. Concluding that the contractor’s exclusion was a sovereign act, the court in
Wilson
emphasized that the order was, as here, issued by a military commander rather than a contracting agent and was “limited strictly to the public defense.”
Wilson,
Conner further contends that even if the exclusion order constituted a public and general act, the government cannot avoid liability because it failed to establish a common-law impossibility defense. As explained in
Winstar,
even where the sovereign acts doctrine applies, “the common-law doctrine of impossibility imposes additional requirements before a party may avoid liability for breach.”
Winstar,
Conner attempts to avoid the consequences of its waiver of the “impossibility” argument by noting that because the sovereign acts doctrine is an affirmative defense, the government had the burden of establishing each element of the defense, including the “impossibility” component. However, the sovereign acts doctrine was the government’s sole defense to Conner’s liability claim and the focus of the argument before the Board. In response to the government’s assertion of the defense, Conner challenged the public and general nature of the exclusion order, disputed its reasonableness, and questioned General Votel’s authority to shut down the construction project. Conner did not, however, suggest that the elements of impossibility were not satisfied. In particular, Conner did not suggest that the shutdown in response to a national emergency was foreseeable or that the government assumed the risk of any such occurrence. Having challenged the government’s assertion of the sovereign acts defense before the Board, Conner was obliged to put forth all of its arguments against the application of that defense. Because Conner failed to argue that the government did not satisfy the “impossibility” requirement of the sovereign acts defense, it has waived that argument for purposes of appeal.
*1380 IV
As an alternative ground for recovery, Conner contends that the Corps of Engineers breached its implied duty to cooperate by failing to issue a suspension of work order after General Votel issued the exclusion order. As the Board found, however, the contracting officer played no part in the decision to restrict access to the Ranger compound. That decision was a sovereign act involving national security, and it was unrelated to any interests of the government as contractor. The contracting officer was under no obligation to issue a suspension оf work order in response to an action taken by the government in its sovereign capacity.
Cf. Urban Plumbing & Heating Co. v. United States,
AFFIRMED.
Notes
. Conner is correct that the fact that the government may havе had lawful authority and
*1379
valid reasons for taking an action is not sufficient to satisfy the "public and general” requirement. Serving the public good is a necessary but insufficient condition for asserting the sovereign acts defense.
