The FX-550 Skygrasper is an aerial support fighter introduced in the anime Mobile Suit Gundam SEED.

The Skygrasper was a fighter aircraft originally designed to support the GAT-X105 Strike Gundam. To fulfill this role, it was given the ability to mount the Strike Gundam's Striker Packs so as to deliver them to the mobile suit during combat, and this removes the need for the mobile suit to return to the hangar of its mothership for re-equipping. In addition, the Skygrasper can utilize many of the Packs' weapons and equipment, 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, allowing it to provide fire support for the Strike Gundam.

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, bombs, etc from the two weapons bays, making it a very capable air superiority fighter in its own right. In fact, the combination of these weapons and the Skygrasper's maneuverability grant it combat capabilities on par with most mobile suits. Like its predecessor, the F-7D Spearhead, the Skygrasper is capable of VTOL. The Skygrasper was eventually put into mass production by the Earth Alliance to support the Dagger series mobile suits that could utilize Striker Packs. These mass production units are mostly identical to the original two units assigned to support the Strike Gundam, except in their color schemes, where they are painted in gray and yellow instead of the original's brighter colors.
