F-16 Update

The F-16 Update, also known as the F-16UD, is an upgraded variant of the F-16 Fighting Falcon which is equipped with JHMCS (Joint Helmet-Mounted Cueing System). The exact method to unlock the F-16UD seems unclear, but suggestions indicate that it can be unlocked by getting a certain amount of score with the F-16, or destroying every Mig-29 in Mission 2.

Differences From The F-16
The exhaust nozzle is more rounded on the F-16UD, and the paint job is white and grey, with a white and blue camouflage-like appearance (though it doesn't have any effect in gameplay). The F-16UD is also slightly easier to land due to its landing gear configuration, which features wider-spaced rear gear.
