When developing Halo 2, Bungie faced numerous delays for various technical reasons. As such many aspects of the story such as vehicles, game play/design, and story elements did not make it into the final version of Halo 2. Many of the elements have been confirmed by such things as videos and commentary on the Limited Edition special DVD.

It may be that the early concept of the Strike Fighter was the SkyHawk mentioned in Halo: The Fall of Reach.
