The AB-11 Attack Bomber is descended from lessons learned from past US and EU close air support jets, with improvements made with modern technology.
The AB-11 appears exclusively in the multi-player map Hindsight for the Coalition to rival the RSA's MRB-131 which also only appears in that map.
Behind the Scenes
The AB-11 was designed by Nathan Campbell, and was modeled by Brian Burrell while they were employed at Kaos Studios.
The vehicle is referred to in the game's files as, "VHW_JET_Bomber", with 'VH' standing for vehicle, 'W' for Western Coalition, 'JET' as vehicle type, and 'Bomber' as the role it plays.
