RTX Corporation’sPratt & Whitney F119 afterburning turbofan engines, so their maintenance and sustainment are key.

The improvements being made on the F119 can quickly transfer to other Pratt & Whitney jet engines—not just the F-35’s F135. So let’s take a look at the $1.5 Billion gross in F119 sustainment the United States Air Force (USAF) just bought.
