AV-22 Sparrowhawk

Sparrowhawk The Sparrowhawk is an aerial vehicle classification of the United Nations Space Command. It is planned to appear in Halo Wars.

Background
Known more readily as just “Hawk,” the Sparrowhawk is a formidable air-to-ground, armor-busting, support aerodyne. The Hawk is still being assessed by command before full production starts while engineers are still working on an experimental propulsion system that has led to failures in the field making the future of this vehicle uncertain. The Hawk first saw actual combat against the Covenant on the surface of Harvest in the final months of that campaign.

Trivia

 * It is a similar vehicle in design to that of Halo 2's deleted Kestrel.
 * Doesn't appear in Halo 3 but UNSC Hornet is similar to Sparrowhawk.
