Pratt & Whitney has secured a $1.5bn contract from the US Department of Defense (DoD) for the production of the tenth low-rate initial production (LRIP) batch of F135 propulsion systems.
Under the contract, the company will supply 99 propulsion systems in total to power all three variants of the F-35 Lightning II joint strike fighter.
The F135 is the derivative of the F119-PW-100 engine advanced turbofan engine that powers the USAF's F-22 Raptor.
Designed to lower maintenance costs, the engine comes with advanced prognostics and health management systems.
Pratt & Whitney F135 Engine Programme vice-president Mark Buongiorno said: "Pratt & Whitney and our supply base remain focused on delivering the F135 propulsion system to the warfighter at or below the cost targets established in 2009 for our US and international customers.
"This agreement for the next lot of F135 engines continues to drive down costs, and we intend to keep up this momentum as we transition from the war on cost initiative and continue to pursue cost saving opportunities."
The contract also includes programme management, engineering support, production non-recurring efforts, spare modules and spare parts.
The F-35 Lightning II is a fifth generation fighter, combining advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations and advanced sustainment.
Three variants of the F-35 will replace the A-10 and F-16 for the USAF, the F/A-18 for the US Navy, the F/A-18 and AV-8B Harrier for the USMC.
