Invincible Fleet is the sixth campaign mission of Ace Combat 04: Shattered Skies. This is mainly an air-to-ground mission as the player is tasked with destroying the large force of warships and vessels known as the Aegir Fleet.


We will launch a surprise attack on the Aegir Fleet while it lies immobilized at Comberth Harbor. This large-scale air strike [sic] will be the largest and the most strategic operation since the transfer of HQ to North Point. You may need to resupply along the way because this operation will be long in duration. Remember, it is imperative that you complete the mission objective and return to base safely.


The player needs to attack the enemy fleet and dock facilities, which are concentrated in four areas at the harbor. The mission's score requirement depends on the player's selected difficulty:

  • Easy or lower: 2,400
  • Normal or higher: 3,000

The player must surpass the point threshold within fifteen minutes to complete the mission.

S Rank

An S rank for this mission requires 5,000 points on Normal difficulty or above (4,000 points on Easy difficulty or below).[1][2]


The Erusians' [sic] so-called "invincible fleet" has been destroyed. Their plans for invading North Point have been delayed indefinitely. Although we are still far from triumphant, this victory gave our troops a much-needed boost in morale.
