Standoff in the Skies II is mission 07B in Ace Combat X: Skies of Deception. It is the second scenario in which Gryphus One fights an unharmed Gleipnir with functional optical camouflage.


"Allied ground forces have finished preparations for an assault on Santa Elva. They're the same troops we rescued from Stand Canyon. The mission will be to retake Santa Elva, a vital transportation route. If we succeed in retaking this city, our capitol Griswall will be within reach. Analysis of the SWBM attack on Cape Aubrey has shown that the shock wave of the missile dissipates before reaching ground level. Therefrore, an assault by our ground forces has a much higher probability of succeeding. The mission can commence any time. The Gleipnir has troubled Aurelia long enough, the time has come to drive it out."


Gryphus 1 is tasked with destroying the airborne fortress Gleipnir once and for all. The optical camouflage must be disabled before the ground forces are wiped out by the Gleipnir's Shock Cannon. After this, the player must destroy the SWBM ports; when an SWBM is launched, dive below the Gleipnir's altitude before it hits.

After all launch ports are destroyed, the Gleipnir will attempt to fire the Shock Cannon at the city. Gryphus 1 must then destroy it before the time runs out.

"We've succeeded in destroying the Gleipnir, as well as taking back Santa Elva. The Santa Elva victory is fantastic news. But even more so, the defeat of the Gleipnir is sure to boost morale and give us a strategic advantage in this war. Luck was certainly on our side though with all that raining debris, it's amazing the city sustained so little damage."


  • If the player does not destroy the Shock Cannon after the mission update, a short cutscene will show the Gleipnir firing the Shock Cannon at Santa Elva before the mission failed screen appears.
  • When the cutscene of Gleipnir crashing plays after the player destroys the Shock Cannon, Eugene Solano erroneously refers Santa Elva as "the capital", which the actual capital of Aurelia is Griswall.
