Lockheed Martin has received a massive $1.12 billion contract from the U.S. government to produce 16 advanced F-16 Block 70 Fighting Falcons for Bahrain.

The “undefinitized contract action award” means that the Royal Bahraini Air Force will become the first operator of the most advanced and capable version of F-16 ever designed.

Moreover, unlike previous versions of the F-16—which were built in Fort Worth, Texas—these new “Vipers” are to be manufactured in Greenville, South Carolina.
