  US Navy officially inducts Triton UAV into service

  Gareth Jennings, London - Jane's Navy International The US Navy (USN) has officially commenced operations of its Northrop Grumman MQ-4C Triton Broad Area Maritime System (BAMS) unmanned aerial vehicle (UAV), it was announced on 1 June. A ceremony to formally induct the high-altitude long-endurance (HALE) UAV into service with Unmanned Patrol Squadron (VUP)-19 – the navy's first unmanned patrol squadron – was held the previous day at Naval Base Ventura County in Point Mugu, California. VP-19 now has two Triton UAVs, which are housed in specially constructed to facilities designed to accommodate their nearly 40 m wingspans. With this milestone, VP-19 will undertake training and trials ahead of the platform's inaugural overseas deployment, which will be to the Pacific island of Guam later this year. For this and later deployments, the Triton will operate in concert with the manned Boeing P-8A Poseidon maritime multimission aircraft. The MQ-4C Triton has been developed from the Block 30 RQ-4N naval variant of the RQ-4 Global Hawk HALE UAV to provide the USN with a persistent maritime intelligence, surveillance, and reconnaissance (ISR) capability in support of a full range of military operations. Designed for high-altitude, long-endurance ISR tasks, the Triton has a range of about 2,000 n miles and, with an endurance of 24 hours, will be able to cover more than 2.7 million sq miles in a single mission. Its payload primarily comprises the AN/ZPY-3 multifunction active-sensor radar. The USN has established the infrastructure to train its Triton operators at Naval Air Station (NAS) Jacksonville in Florida. Operators undergo training under the supervision of Patrol Squadron (VP) 30 at the 11,600 m2 Integrated Test Center (ITC), which is also used for the training of P-8A Poseidon and P-3 Orion crews. http://www.janes.com/article/80602/us-navy-officially-inducts-triton-uav-into-service

  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
