The United States Air Force
(USAF) and four of its NATO partners are the primary operators of F-16 Fighting Falcon
. With the evolution of sales under Foreign Military Sales
(FMS) contracts, many other air forces have also acquired F-16s. Most nations that have been sold F-16s continue to use them as of 2010. Sometimes despite the fact, that delivered F-16s had many malfunctions and were often grounded, as in case of Poland//en.wikipedia.org/wiki/F-16_Fighting_Falcon_operators#Poland
The F-16 is still in demand today, and many air forces are looking to replace aging inventories with F-16s. Because the USAF has steadily upgraded its F-16 inventory, it will sometimes sell older aircraft it considers obsolete as surplus
Excess Defense Articles (EDAs) or as "knockdown"
aircraft to supplement spares inventories
United States operators
Several commands of the United States Air Force
(USAF) as well as the United States Navy
(USN) and National Aeronautics and Space Administration
