The AV-19 SkyHawk is a supersonic jet capable of vertical take-off and landing. The fighter is designed to be very maneuverable and is able to execute sharp turns, even at high speeds. Its chassis is somewhat similar to the AV-22 Sparrowhawk's, albeit the main body is wider and the tail lacks the twin fins. As far as armaments are concerned, the SkyHawk has four 50mm automatic cannons, a pair mounted on either side of the cockpit, and at least two missiles mounted under either wing.
The SkyHawk is most likely employed primarily by the UNSC Air Force.
Several of these craft were based at Fairchild Field on Reach in 30th of August 2552, and one was dispatched by Colonel James Ackerson to attack John-117 and Cortana, during their test of the Mjolnir Mark V armor, its new energy shield technology and the Mark V's AI integration ability. Defying all expectations, the Spartan-II and Cortana managed to endure its cannons' strafing run and avoid its guided anti-tank missiles by simply deflecting it at the last moment, proving the Spartan-AI team far more successful than ever expected.
- It has only been seen in the Halo: The Fall of Reach novel and its comic adaption, Halo: Fall of Reach, and does not appear in any other media.
- It shares its name with a real life fighter jet, named the A-4 Skyhawk, and may be its spiritual successor, since both have a similar role in their respective militaries.
- Like many other UNSC vehicles, its namesake is an animal.
