"WASHINGTON — The Pentagon has reached an agreement with Pratt & Whitney for the ninth low rate initial production (LRIP) lot of F135 engines, which power the F-35 joint strike fighter.
The agreement, worth an estimated $1.4 billion over the life of the production lot, covers 66 engines, as well as spares, extra parts, and support from the Connecticut-based engine manufacturer. Specifically, the breakdown is 53 conventional takeoff and landing engines, used in the F-35A and F-35C models, and 13 short takeoff and vertical landing models used for the F-35B model.
The engine lot also includes engines for five international partners and customers: Italy, Norway, Israel, Japan and the United Kingdom. Engines under this contract should begin delivery before the end of the year, according to a Pratt statement."
