The Kestrel is an UNSC aircraft seen in the Halo 2 Collector's Edition disc that was cut from the game.
Trivia
- Since the Kestrel is an aircraft, it may have had weapons similar to the Hornet's defense systems, such as the machine gun and missiles. It may also have been used to transport troops quickly if it were to have a troop bay, much like modern helicopters.
- The name Kestrel was also that of a cargo ship in Halo: The Cole Protocol.
- It was placed by modders into custom maps available only to Halo: Custom Edition.
- The Kestrel may have been an early version of the Hornet or Hawk, as both are quite similar looking.
- The name Kestrel was found in the Halo Combat Evolved game code.
