AV-19 SkyHawk

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

Background
The SkyHawk is equipped with four 50 calibre cannons, which are 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.
