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.”

7/29/2020 By Connie Lee The Air Force wants to shake up the industrial base and is looking to move away from relying on large, traditional prime contractors and instead bring in new talent, the service's top weapons buyer said. The service needs “a new industrial base model that's not a defense industrial base model,” said Will Roper, the Air Force's assistant secretary for acquisition, technology and logistics. “We have to have a new model that encourages companies to come in and work with [the] military, but not necessarily put them on a path to become a defense prime.” Such an approach would help the United States counter adversaries such as China, which has a larger industrial base, Roper said during a webinar hosted by the Mitchell Institute for Aerospace Studies. The 2018 National Defense Strategy listed China as a great power competitor. “Our defense primes are going to continue to be heavy movers and shakers for us, but we're not going to win against China long term” without bringing in additional industry players, he said. “If they've got a nationalized industrial base, they have access to their entire talent pool. They have access to every company that's within their border. And we are only working with a small subset” of industry. To encourage these changes, the service has been taking steps such as setting up AFVentures.The effort is a collaboration between the Air Force Small Business Innovation Research/Small Business Technology Transfer Program and AFWERX to invest in companies that may have technology useful to the military. Some of the funding is coming from private investors. Over the last year and a half, the service has added over 1,000 companies to its industrial roster, Roper said. Many of these firms are working on research-and-development prototypes, which may lead to contracts for steady work later down the road, he noted. Through AFWERX, the Air Force has been giving out awards and making different levels of “bets” on technology, with small bets totaling between $50,000 to $75,000; medium bets worth between $1 million to $3 million; and big bets from $5 million to $50 million, according to the service. “It begins with getting companies through that front door so that they can move on to steady-state contracts and programs of record supporting the warfighters,” Roper said. Until recently the push to move away from the standard defense industrial base model through AFWERX has only been experimental, he noted. The service must make it the standard practice for acquiring new weapons, he said. “This is the year that we have to make it codified, steady-state across the Air and Space Force,” he said. “It's imperative. It's the bread and butter of winning the competition long term.” https://www.nationaldefensemagazine.org/articles/2020/7/29/air-force-eyes-new-industrial-base-model
