The F-16 Fighting Falcon is a multirole jet fighter aircraft originally developed by General Dynamics for the United States Air Force.
The F-16 is scheduled to remain in service with the U.S. Air Force until 2025. The planned replacement is the F-35 Lightning II, which is scheduled to enter service in 2011 and will gradually begin replacing a number of multirole aircraft among the air forces of the program's member nations.
The F-16E (single seat) and F-16F (two seat) are the latest version of the F-16. They do not exist in the USAF inventory and are currently an export variant only. Originally, the single-seat version of the F-16XL was to have been designated F-16E, with the twin-seat variant designated F-16F. This was sidelined by the Air Force's selection of the competing F-15E Strike Eagle in the Enhanced Tactical Fighter fly-off in 1984. The 'Block 60' designation had also previously been set aside in 1989 for the A-16, but this model was also dropped. The F-16E/F designation now belongs to a special version developed especially for the United Arab Emirates (UAE), and is sometimes unofficially called the 'Desert Falcon'.
