Phoenix

"A fully autonomous vehicle, the Phoenix serves as a remote-bombing device, capable of delivering staggering ordnance to a specified target."

- UT2004 website

The Phoenix was originally planned to be a driveable bomber air vehicle, but was cut from the game in that form and instead is summoned by use of the Target Painter to perform an air strike. The Phoenix travels in a straight line towards its target, and begins releasing bombs as it nears the target. These bombs explode in sequence like small Redeemers, killing anyone and anything in a wide area. When a player successfully paints a target for an air strike, all players are warned of an incoming airstrike.

The Phoenix can be shot down to prevent it from completing its bombing sweep. The Shock Rifle works pretty well for this purpose. When destroyed, the bomber will crash down, detonating in a full-size Redeemer explosion on impact.
