Pratt & Whitney Awarded Contract for F135 Engine Modernization Study

Seapower Staff

EAST HARTFORD, Conn. — Pratt & Whitney, a division of Raytheon Technologies Corp., has been awarded a $1.5M contract to conduct an F135 modernization study and operational assessment by the F-35 Joint Program Office to determine specific propulsion system growth requirements for Block 4.2 F-35 aircraft and beyond, the company said in an Oct. 20 release. The study is expected to conclude in March 2021.

“This award is a significant milestone for the program and the warfighter, as we look to ensure the F135 propulsion system continues to provide the foundation for all air vehicle capability requirements over the full lifecycle of the F-35,” said Matthew Bromberg, president, Pratt & Whitney Military Engines. “As we look to the future, growth in aircraft capability must be met with matched propulsion modernization. Fortunately, the F135 has ample design margin to support agile and affordable upgrades that will enable all F-35 operators to keep pace with evolving threat environments.”

Under this award, Pratt & Whitney will assess F135 engine enhancements required to support future F-35 weapon system capability requirements across all F-35 variants beginning with Block 4.2 aircraft. The scope of the assessment focuses on enhancements addressing improvements to up and away thrust, powered lift thrust, power and thermal management capacity, and fuel burn reduction.

Designed with the knowledge that operational environments will evolve and threats will advance, the F135 is postured to meet future F-35 capability requirements. Its modular design and advanced digital architecture allow for the agile development and spiral insertion of both hardware and software upgrades. As part of the study, Pratt & Whitney's GATORWORKS organization will complete the conceptual design and analysis of multiple F135 Engine Enhancement Package (EEP) growth options with phased insertion plans.

Leveraging significant U.S. Government and Pratt & Whitney investment in next generation adaptive propulsion technologies, Pratt & Whitney's EEP approach offers low risk, variant-common upgrade options for the F135 that provide increased performance aligned with the program's continuous capability development and delivery strategy and serve as a critical enabler for future capability growth of the F-35 weapon system.

The combat-proven F135 is the most advanced operational fighter engine in the world, delivering 26% more thrust, 116% more powered lift, and more than a 300% increase in power and thermal management over 4th generation fighter engines – all with a demonstrated mission capability rate of greater than 94%.

“Built upon decades of combat propulsion experience, the F135 provides the warfighter with a critical technological advantage over adversaries at an unparalleled value to the taxpayer,” said Bromberg. “With more than 40,000 pounds of thrust, unmatched low-observable signature, world-class thermal management, and innovative engine control system, the F135 is a critical enabler of the F-35 weapons system and of operations conducted in advanced threat environments – a core element of the National Defense Strategy.”

    Mattis says US-France in talks about loosening export limits on cruise missile

    By: Pierre Tran PARIS – U.S. defense officials are in detailed talks with French counterparts on a request for the sale of American components built into French cruise missiles, U.S. Defense Secretary Jim Mattis said. Asked by a French journalist about Washington blocking the sale of the Scalp long-range weapon to Egypt and Qatar, Mattis said American and French staff were meeting on that very issue even as a press conference was being held. “We discussed this,” he said. “We also have our staffs meeting. We have an invitation out to France to answer two final questions. The meetings are going on as we speak.” Mattis, on his first visit to Paris as defense secretary, was speaking at a joint press conference with his French counterpart, Armed Forces Minister Florence Parly, held at Brienne House. The two issues to be resolved target “certain technologies” that the United States only shares with its closest allies, including France, and whether that technology can be further transferred, and how France can protect that technology, he said. “Right now we don't have a final answer but it is all going in the right direction,” he said. “And it was a very fruitful discussion today. Our staffs are working this forward right now.” The conundrum stems from the French sale to Egypt and Qatar of Scalp cruise missiles to arm Dassault Rafale fighter jets. The weapons include U.S. parts, leading Washington to evoke the International Traffic in Arms Regulations regime. Parly, meanwhile, thanked Mattis, for help in gaining U.S. authorization for arming French Reaper drones, cleared for fitting by the end of the year. U.S. President Donald Trump plans to come to Paris to mark the Nov. 11 Armistice Day, she said. That date is highly significant for France, marking the end of World War I, in which millions of troops died in the trenches. Mattis said he was not concerned about a drive by France and Germany to build a stronger European defense, as there were some issues which were “of interest only to Europeans.” As long as the European drive would not duplicate NATO or compete for alliance forces, “we see this in a positive direction,” he said. Mattis earlier met French President Emmanuel Macron and would go on to Brussels for a NATO ministerial meeting. https://www.defensenews.com/global/europe/2018/10/02/mattis-offers-easing-of-us-export-limits-on-french-cruise-missile
