From news article:
November 4, 2011: The U.S. has agreed to supply Turkey with source code for F-16 fire control and flight system software, so that Turkey can modify F-16 software to use Turkish made weapons and equipment. This will be part of a Turkish refurbishment of 213 of their F-16s. This will cost about $5.2 million per aircraft, and include a lot of Turkish made equipment. Over the last decade, Turkey has been producing more military gear locally, and now produces over half its military equipment needs.
