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.

    Australian subs to get sonar boost

    Pierre Tran PARIS — Thales has sealed a deal worth AU $230 million (U.S. $169 million) to boost the sonar capability on the Australian Navy's six-strong fleet of Collins submarines, drawing on teams working in Britain, France and Australia. “Australia's strategic priority on enhancing its submarine capability will be supported by Thales through major upgrades of the sonar system on all six Collins class submarines,” the electronics company said in a June 14 statement. Thales' work is part of a total AU $542 million project to install a modular cylindrical array, based on sonar 2076 submarine technology developed by its British unit, the company said. That modular array replaces a cylindrical array installed in the 1980s. A new flank array from the Thales French unit will replace the existing system. Thales will work with the combat system integrator, Raytheon Australia, which will integrate products from other suppliers including Sonartech Atlas and L3 Oceania. The sonar work will support more than 140 local jobs, of which 50 will be Thales staff at its Rydalmere plant, western Sydney, the company said. That deal follows Thales winning in November 2016 a contract for design and pre-production to upgrade cylindrical and flank array sonars, including onboard processing, on the Collins boats. Separately, Thales hopes to win business worth more than AU $1.6 billion to supply sonars and other equipment on the Australian acquisition of 12 ocean-going attack submarines. Lockheed Martin is combat systems integrator and Naval Group the prime contractor on that program worth some AU $50 billion. https://www.defensenews.com/global/asia-pacific/2018/06/19/australian-subs-to-get-sonar-boost/

    Ratier-Figeac : nouvelle commande d'hélices pour les avions militaires américains

    Collins Aerospace, groupe américain dont fait partie Ratier-Figeac, annonce avoir reçu un contrat pluriannuel pour la fourniture de nouveaux systèmes d'hélices NP2000 pour les avions Hawkeye E-2D de Northrop Grumman. Ces systèmes hélices seront fabriqués par Ratier-Figeac (Lot), qui a récemment investi dans la construction d'un centre d'excellence des hélices d'avion, qui devrait être inauguré à l'automne, comme le précise Jean-François Chanut, président de Ratier Figeac et directeur général de la branche Propeller Systems de Collins Aerospace. L'assemblage final des pièces sera réalisé aux Etats-Unis, sur le site de Windsor Locks (Connecticut). « Avec sa nouvelle hélice NP2000 et son système numérique de commande d'hélice électronique, Collins Aerospace continue de fournir aux opérateurs d'E-2D Advanced Hawkeye un temps et un coût de maintenance réduits, ainsi qu'un confort et une sécurité améliorés pour l'équipage », souligne Collins Aerospace.

  • New partnerships formed in quest to snag US Army Stryker up-gunning deal

    New partnerships formed in quest to snag US Army Stryker up-gunning deal

    by Ashley Roque Industry is bracing for surprise entries and team changes in the US Army's up-gunning competition with at least one big switch up: Pratt Miller partnering up with Rafael Defence and Oshkosh Defence. After a two-and-a-half-month deadline extension, all Medium Calibre Weapons System (MCWS) programme proposals and bid samples are due to the army on 24 August. Although many vendors are remaining tight lipped over whether they are still competing, Janes has confirmed with multiple, wholly separate, sources that Pratt Miller is no longer teaming up with CMI Defence and is now saddled up with Rafael and Oshkosh for its bid. The service declined to comment on any team changes and said specific vendor information, including system performance and on-going participation, are considered “source selection sensitive”. “The US [government] does not and has not provided vendor direction on who to partner with or what systems to utilise to protect the integrity of the competition,” Ashley John, director for public and congressional affairs for the Program Executive Office for Ground Combat Systems, told Janes on 12 August. “Each vendor partnership is independent of government input and has been developed directly from party to party.” Under the competition, the army wants to select a team to outfit Stryker vehicles with 30 mm cannons. Service plans called for a two-phased, concurrent approach involving a design integration study phase to help inform requirements development and the acquisition strategy, and a separate Stryker MCWS request for proposal (RFP). https://www.janes.com/defence-news/news-detail/new-partnerships-formed-in-quest-to-snag-us-army-stryker-up-gunning-deal
