  Pratt & Whitney is pitching a new version of the F-35 engine

  WASHINGTON — Pratt & Whitney is developing upgrades to the F-35's engine that will give it the power and cooling necessary to make the U.S. Defense Department's most sensor-heavy fighter jet even more of a powerhouse. The new Growth Option 2.0 upgrade for the F135 engine, launched on Tuesday, adds a more advanced power and thermal management system that could be used to help the F-35 incorporate new weapons and sensors, the company said. It also integrates a new compressor and turbine technologies that yield greater thrust and fuel savings, which were part of the Growth Option 1.0 concept unveiled in 2017. In a June 12 interview with Defense News, Matthew Bromberg, president of Pratt & Whitney's military engines unit, said the company decided to work on improvements to the F135's power and thermal management system, or PTMS, based on feedback from the F-35 Joint Program Office. Pratt in 2017 tested an early version of the Growth Option 1.0 motor called the fuel burn reduction demonstrator engine, which demonstrated that the upgrade could improve thrust by up to 10 percent and reduce fuel consumption by up to 6 percent. But while the community that flies the F-35B short-takeoff-and-vertical-landing variant was gung-ho on the thrust improvements, the JPO said that better power and cooling was what was really needed — especially as the program transitions from the development phase to modernization, also known as Block 4 or Continuous Capability Development and Delivery, Bromberg said. Pratt has already begun testing some technologies from the Growth Option 2.0 suite in various rigs and demonstrators. Bromberg called the upgrades “relatively low risk” and said it could probably be proven out in a four-year technology demonstration program. But he declined to talk about completed testing or to quantify the new power and cooling improvements, saying only that they were “significant.” Although the Defense Department hasn't signed onto an upgraded F135 engine as part of the Continuous Capability Development and Delivery effort, Pratt executives have been hopeful that it will do so as it finalizes that strategy. “As the F-35 program moves forward with the Continuous Capability Development and Delivery strategy, we strive to stay in front of propulsion advances needed to enable F-35 modernization,” Bromberg said in a statement. “We're continuously assessing customer needs and responding with technology options to keep them ahead of evolving threats.” https://www.defensenews.com/industry/2018/06/13/pratt-whitney-is-pitching-a-new-version-of-the-f-35-engine/

  ‘A Little Bit Disruptive’: Murray & McCarthy On Army Futures Command

  By SYDNEY J. FREEDBERG JR. "It's establishing buy-in over the next three, four, five years from the institution (of the Army)," Gen. Murray said. "It's about establishing buy-in on Capitol Hill, because if I don't have buy-in there, this won't survive.” DEFENSE NEWS CONFERENCE: The Army's new Futures Command won't tear down the most failure–prone procurement system in the entire US military. Instead, both its commander and the Army's No. 2 civilian emphasize they want to be just “a little bit disruptive” and “work with the institution.” That will disappoint critics of the service's chronically troubled acquisition programs who saw the Army's much-touted “biggest reorganization in 40 years” as an opportunity to tear the whole thing down and start again. The necessary change to Army culture “is going to take time,” brand-new four-star Gen. John “Mike” Murray said here yesterday, “and I think you do that by being a little bit disruptive, but not being so disruptive you upset the apple cart.” “It's hard, Sydney, because you know, you have to work with the institution,” Undersecretary Ryan McCarthy told me after he and Murray addressed the conference. “You don't want to go in there and just break things.” Work Through The Pain Reform's still plenty painful, acknowledged McCarthy, who's played a leading role in round after round of budget reviews, cutting some programs to free up funding for the Army's Big Six priorities. The choices were especially hard for 2024 and beyond, when top priorities like robotic armored vehicles and high-speed aircraft move from the laboratory to full-up prototypes. “You've got a lot of people out investing, and they're all doing good things, but they weren't the priorities of the leadership,” McCarthy told me yesterday. “You have to explain to folks why you're doing what you're doing. You need them focused on the priorities of the institution” – that is, of the Army as a whole, as set by leadership, rather than of bureaucratic fiefdoms with a long history of going their own way. But what about the pushback from constituencies who see their priorities being cut, particularly upgrades to keep current platforms combat-ready until their replacements finally arrive? “If you don't accept the risk that you talked about, (if you don't) slow down or stop the upgrade of legacy systems, you never get to next generation equipment,” brand-new four-star Gen. John “Mike” Murray said here yesterday, “and I think you do that by being a little bit disruptive, but not being so disruptive you upset the apple cart.” In other words, funding for incremental upgrades will crowd out funding for potential breakthroughs. That's largely because the incremental approach looks lower-risk – right up to the point where the enemy fields something revolutionary that your evolutionary approach can't counter.
