Excalibur Onslaught I is a Special Raid mission in Ace Combat Infinity that has a chance to appear after completing a previous Online Co-Op Mission. It takes place in an unknown location, where the USEA Federation is operating a giant laser tower named Excalibur. Players must work together to destroy it.


We have discovered that the enemy has secretly procured and modified a chemical laser weapon called "Excalibur," previously developed by a hostile nation for national defense. Leaving such a weapon in play will have a serious impact on all other upcoming operations.
The Military Staff Committee has therefore officially issued an operation to destroy Excalibur.
The exact modifications made to the weapon by the enemy remain unknown. All units, remain alert at all times during the mission.


Players spawn at the southeast corner of the map. Excalibur is located roughly in the center of the map, and will immediately commence firing on the players. The tower will fire its laser at the players directly. So, players are to avoid flying in a sector of the map indicated to be the tower's effective line of fire.

Radar jamming facilities consisting of radar bunkers with AA guns, XSAMs, and tanks as their defenses are set up in four locations and all of them are located between the players' spawn point and the Excalibur. Players' first objective is to destroy all of the jamming facilities to clear the jamming.

Next, players must fly to the tower and destroy its power generators and targeting towers. At this point, the enemy will launch MQ-90 drones. Also, the tower will now defend itself by firing at a series of reflective mirrors equipped on trucks and airships to build a network of laser beams.

After the generators and the towers are destroyed, players must destroy Excalibur's topmost laser port.

Finally, players must destroy the tower itself by aiming at its center in order to complete the mission.
