The SkyHawk is a supersonic VTOL-capable jumpjet that can execute quick turns at high speeds. The fighter bears a very strong resemblance to the AV-22 Sparrowhawk, though it lacks the Sparrowhawk's twin tail. It is armed with four 50mm cannons that flank the cockpit, as well as two fully-customisable weapons pylons capable of fitting - among other munitions - Scorpion anti-tank missiles. As such, the SkyHawk is capable of dealing inordinate damage relative to its small size.
Several SkyHawks were located at Fairchild Airfield on Reach during the Fall of Reach in summer 2552. On August 29, a SkyHawk was dispatched by Colonel James Ackerson to attack SPARTAN John-117 and the AI Cortana during a test of AI integration with the Mark V MJOLNIR armor. With Cortana's assistance, the SPARTAN was able to endure the SkyHawk's cannons' strafing run. He then avoided one of its guided anti-tank missile by deflecting it at the last moment. The test showed the Spartan-AI team to be far more successful than expected.
