The FX-550 Skygrasper is an atmospheric support fighter in the Cosmic Era timeline, seen in the Mobile Suit Gundam SEED series. It was originally designed to support the GAT-X105 Strike Gundam by being compatible with Striker Packs for aided combat and/or a mid-battle armament delivery system.

Designed as a support craft, the main role of the Skygrasper was to deliver Striker Packs to the GAT-X105 Strike in battle, removing the need to return to the hanger for re-equipping. In addition, since the Skygrasper is compatible with the Striker Packs itself, it can utilize many of the Packs' weapons and equipment during combat, such as the Aile Striker's thrusters for additional speed and agility, the Sword Striker's anti-ship sword and rocket anchor for close range attacks, and the Launcher Striker's beam cannon for enhanced long-range firepower. On its own, the Skygrasper is armed with a turret-mounted beam cannon, two medium caliber cannons, four machine guns, and can launch anti-ship missiles from the two weapons bay, making it a very capable air superiority fighter in its own right. Like its predecessor, the Skygrasper is also capable of VTOL.
