  USAF Opens Bidding Phase Of B-52 Re-Engine Competition

  Steve Trimble May 20, 2020 The U.S. Air Force has kicked off a three-way competition to re-engine the entire 76-aircraft B-52 fleet from 2021 to 2035. The request for proposals (RFP) released on May 19 invites bids from GE Aviation, Pratt & Whitney and Rolls-Royce to supply 608 engines to replace each of the eight, 60-year-old, 16,000 lb.-thrust P&W TF33 turbofans on the heavy bomber. GE can choose between the CF34 or Passport engine or offer both. P&W has proposed the PW800. Rolls-Royce will offer a military version of the BR.725. The Air Force RFP lays out a two-step selection process. In step one, companies must submit “virtual” prototypes of their engine, meaning a digital design with integrated models for manufacturing, performance and sustainment. Step 2 calls for the traditional engine source selection process, which will be informed by the data from the virtual prototypes and an integration risk analysis completed in the first step. The Air Force has said the TF33 engines that now power the B-52 cannot be sustained practically beyond 2030. The Cold War jet, meanwhile, is expected to continue operating beyond 2050, outliving the B-2 and B-1B fleets scheduled for retirement in the 2030s. Armed with a new class of hypersonic and long-range missiles, including the nuclear Long-Range Stand-Off Weapon, the B-52 will perform the standoff mission, while the B-21 penetrates into contested airspace. https://aviationweek.com/defense-space/aircraft-propulsion/usaf-opens-bidding-phase-b-52-re-engine-competition

  Marines, Navy Wrestle With How To Upgun Amphibs

  By SYDNEY J. FREEDBERG JR. The Marines want Vertical Launch System missile tubes on their new amphibious ships -- but the Navy isn't planning to leave room for them. ARLINGTON: The Marines want better-armed amphibious warships for high-end combat, but there's no money in the budget and little room on the ships for their preferred solution, the Vertical Launch System. That leaves them looking at less capable but more affordable upgrades. Those range from bolting small Naval Strike Missile pods onto the deck – as on the Littoral Combat Ship – to parking a HIMARS missile-launcher truck on the back of the ship – as they tested during last year's Dawn Blitz wargames. Why does this matter? In a major war against Russia or China, or even Iran, amphibious warships — as currently equipped — would have to rely on escorting destroyers both defensively, to shoot down attacking missiles and airplanes, and offensively, sinking enemy ships and bombarding targets ashore. But those destroyers might not always be available and, even if they are, they might overwhelmed by the sheer volume of incoming fire. So the Marines want better-armed amphibs that can, ideally, operate unescorted or, at minimum, take on some of the burden of their own defense. To do that, “the naval force must upgrade the C2 (command and control) suites and introduce Vertical Launch Systems,” Lt. Gen. Brian Beaudreault, the Marines' three-star deputy commandant for plans, policies, & operations, told the Surface Navy Association conference on Wednesday. But, I asked him during Q&A, is there actually any money in the budget to add VLS to amphibs? “I'm not aware that there's funding in the program for VLS,” said Beaudreault, who oversees Marine budgeting. “We can't afford as a Marine Corps to put it in there.” Full article: https://breakingdefense.com/2019/01/marines-navy-wrestle-with-how-to-upgun-amphibs
