Latest updates[?]: Raytheon and Pratt and Whitney Military Engines won a $642 million
deal, which provides for the procurement of performance-based logistics activities including maintenance of support equipment, common program activities, unique and common base recurring sustainment, repair of repairables, field service representatives, common replenishment spares, conventional take-off and landing/carrier variant F135 unique maintenance services and short take-off and landing F135 unique services in support of the
F-35 Lightning II F135 propulsion system for the Air Force, Marine Corps, Navy, non-Department of Defense participants and Foreign Military Sales customers. Pratt & Whitney's F135 propulsion system powers all the three variants of F-35, the combat-proven fighter jet developed by defense major Lockheed Martin LMT, with BAE Systems BAESY and Northrop Grumman NOC being the co-manufacturers. Notably,
F135 delivers more than 40,000 lbs. of thrust and unmatched advances in safety, design, performance, and reliability. An initial contract obligation amounting to $215.5 million will come from the US military's fiscal 2021 operation and maintenance funds. Work will run at Eglin Air Force Base in Florida; Hill AFB in Utah; Edwards AFB in California; Luke AFB in Arizona; Beaufort Marine Corps Air Station in South Carolina; Oklahoma City; East Hartford, Connecticut; and Camari, Italy, through November 2021.
Lockheed Martin and Pratt & Whitney have successfully performed the first start of an F-35 Joint Strike Fighter aircraft test engine, using an integrated power package (IPP) that the functions traditionally performed by the auxiliary power system, emergency power system, and environmental control into a single system. The system was used to start a Pratt & Whitney F135 short-takeoff/vertical-landing (STOVL) engine at the company’s advanced test facility in West Palm Beach, FL. The IPP is a subsystem of the F-35 Power and Thermal Management System (PTMS).
The JSF program has targeted the successful IPP engine start as a major milestone since the beginning of the System Development and Demonstration phase of the program in 2001. The achievement paves the way for additional development testing in preparation for the F-35’s first flight in 2006, and comes about a month after the Pratt & Whitney F135 System Development and Demonstration (SDD) program successfully completed the post test Critical Design Review (CDR) by the Joint Strike Fighter (JSF) Joint Program Office (JPO). The JPO review found that the F135 propulsion system has met all review objectives and is on track to deliver the first flight test engine later this year.
