From Halopedia, the Halo wiki
There are similarly, less armed versions of the Falcon in Halo: Reach.
The Transport Hornet is identical in most aspects to the original AV-14 - its primary difference is the lack of the missile launchers found on the base Hornet variant. The Transport Hornet has been seen bearing a white paint scheme, in contrast with the olive traditionally associated with UNSC aircraft.
The Transport Hornet was introduced into Halo 3 with the release of the Legendary Map Pack map Avalanche. The Hornet in this map was adjusted for balance reasons to make it viable for multiplayer play.
