WASHINGTON (Sputnik) — The contract also covers components, parts and materials associated with the procurement of 38 F135-PW conventional take-off and landing propulsion systems for the US Air Force, Marine Corps and for 25 of the systems for foreign countries, the Defense Department added.
"United Technologies, Pratt and Whitney Military Engines is being awarded a $1.038 million contract for the production of F-35 Lightning II Propulsion units for the US Air Force, Navy/Marine Corps, international partners and foreign military sales (FMS) customers," the announcement said on Monday.
The controversial fighter jet has undergone a number of setbacks throughout its development. It has been beset by technical problems and cost overruns, pushing its expected total project cost to some $1.5 trillion over its 55-year lifespan, making it the most expensive US weapons program.
