AV-19 SkyHawk

SkyHawk The Skyhawk is a United Nations Space Command Strike Fighter.

Background
The SkyHawk is equipped with four 50mm cannons, which are so much more powerful than standard infantry chain-guns that they are said to have "made the chain-guns look like peashooters." They also carry Scorpion Anti-Tank missiles. Several of these craft were located at Fairchild Field on Reach, and one was dispatched by Colonel James Ackerson to attack SPARTAN-117 and Cortana during their test of the MJOLNIR Mark V Battle Armor and its new shield technology in 2552. Despite all expectations, the Spartan and Cortana managed to avoid it's guided anti-tank missiles by simply deflecting it at the last moment, proving the Spartan AI team far more successful than ever expected. These aircraft are capable of supersonic flight and can execute quick turns at maximum speed.
