Aegis ships (sometimes referred to as Aegis-class cruisers or Aegis destroyers[1]) are a special type of warship exclusively named in Ace Combat games. These warships typically feature a number of powerful weapons already, but Aegis-equipped vessels combine these weapons into one sophisticated computer array known as the Aegis Combat System, allowing for advanced radar tracking for weapons fire.

More recently, ships possessing the Aegis Combat System also feature integrated CIWS systems for protection against incoming fire. Destroying these requires a volley of attacks from various sources to overwhelm the onboard computers. LASMs and LACMs, when employed from long range, can also bypass these defenses fairly easily.


The chief difference between an Aegis ship and other naval ships is that an Aegis Ship will have two SAM launchers that can either target the player or be targeted by the player. In Ace Combat 6 and Ace Combat Infinity, SAMs were replaced with two VLS which are similar to the enhanced XSAM.

In Ace Combat Infinity, a special variant of Aegis ships is featured in the Naval Team Deathmatch mode. These versions feature the aforementioned CIWS targets that will destroy missiles that are fired at a distance at either the Aegis ship or the ships around it, incensing the player to target them first. The CIWS will continue to respawn if destroyed until the Aegis itself is destroyed.



An Erusean Aegis-equipped cruiser was attempting to escape with several other ships during ISAF's Operation Rough Seas, it was sunk along with the rest of the Aegir Fleet.[2]

During the Circum-Pacific War, both Yuktobania and Osea operated ships utilizing the Aegis Combat System. The Osean Aegis ship OFS Excalibur was attacked by the Yuktobanian Air Force during the Bombing of St. Hewlett.[3] The Osean OFS Halcyon and Yuktobanian Kaniak were sunk along with their respective fleets by Razgriz Squadron during Operation Glory Horn.[4]

In 2016, amidst the Emmeria-Estovakia War, the Estovakian Navy deployed Aegis-equipped ships against the Republic of Emmeria Navy's 2nd Fleet during the San Loma Assault and Operation Free Gracemeria;[5] The Emmerian Aegis vessel Viola participated in the San Loma Assault, where it assisted the 2nd Fleet recapture Doypalm Bay.[1]

Several Aegis-equipped ships were deployed in battle during the Lighthouse War, including the first appearance of the Admiral Gorshkov-class frigate (in a fictional Aegis configuration) under the Erusean Navy. At least two of these vessels were assigned to the Njord Fleet to provide anti-aircraft defense.[6] Erusean Aegis vessels were sunk in Anchorhead during Operation Domino[7] and in Farbanti during Operation Giant's Step.[8] The Osean Federation also possessed Aegis-equipped destroyers and cruisers, using them to escort Osea's remaining aircraft carriers[citation needed] and later on to hunt down the Alicorn.[9]

Leasath fielded Aegis ships during the Aurelian War at Terminus Island[10] and the Danern Straits.[11]

Joint Assault universe[]

The Valahia deployed an Aegis warship to escort a supply ship carrying nuclear fuel across the Dardanelles after all escorting cruisers were sunk by the Antares Squadron.[12] The Golden Axe Plan Private Army also utilized several Aegis ships to attack San Francisco as part of the final phase of the titular plan.[13]

Assault Horizon universe[]

The USS Anzio supported the defense of Washington, D.C. from NRF remnants; however, the crew was forced to abandon ship after several NRF fighters turned kamikaze and crashed into the ship when they were shot down.[14]

Infinity universe[]

Aegis ships were used by both the United Nations Forces and acquired by the USEA Federation during its uprising. These ships were used by the latter all around the world, including Tokyo, Comona Base, and the Adriatic Sea.
