From Halopedia, the Halo wiki
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 Scorpion anti-tank missiles.
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.
