  L3Harris to deliver Iver4 underwater drone to Navy

  By: Chiara Vercellone WASHINGTON — The Pentagon's Defense Innovation Unit has selected L3Harris Technologies to provide the Navy with an underwater drone for use in expeditionary undersea missions, according to a Jan. 14 news release from the company. As part of the contract, L3Harris will deliver for testing an Iver4-900 PW unmanned undersea vehicle, as well as two field swappable modular payload sections, which, along with additional sensors, will allow the vehicle to detect, classify, localize and identify targets on the ocean floor, the release said. An earlier version of the drone was already sent to the Navy, but under this contract, the company will deliver a version modified to fit the Navy's requirements, a company spokeswoman told Defense News. She would not share the value of the contract. “The Iver4 is leading the next generation of small class UUVs,” said Daryl Slocum, vice president of unmanned maritime systems at L3Harris Technologies. “This platform has been custom-built to address the needs of the Expeditionary Mine Countermeasures and Explosive Ordnance Disposal communities.” The contract award comes as the Navy seeks to bolster its unmanned inventory. Congress recently approved the purchase of two large unmanned surface vessels for the service. In 2019, L3Harris received a contract from the University of Southern Mississippi for an older version of the underwater drone to be used by the university's school of ocean science and engineering. https://www.c4isrnet.com/unmanned/2020/01/15/l3harris-to-deliver-iver4-underwater-drone-to-us-navy

  US Air Force launches contest to replace the B-52 bomber’s engine

  By: Valerie Insinna   15 hours ago WASHINGTON — General Electric, Rolls-Royce, and Pratt & Whitney will compete for the chance to outfit the U.S. Air Force's B-52 bomber fleet with new engines, with a contract award projected for June 2021. The Air Force released a request for proposals for the B-52 Commercial Engine Replacement Program to the three companies on May 19. The engine makers are already under contract to create digital prototypes, and they have until July 22 to submit final proposals, the solicitation stated. The Air Force operates 76 B-52s, each outfitted with eight TF33 engines. The service plans to order 608 new engines, plus spares and support, from the winner of the competition. The public version of the RFP obscures the estimated value of the program, which is projected to extend from 2021 to 2035. Pratt & Whitney, which manufactured the TF33 currently onboard the B-52, has stated it will propose the PW800. “Its industry-leading reliability, robust sustainment infrastructure, and significant fuel efficiency savings will greatly improve the legendary bomber and keep it flying for decades to come,” said Chris Johnson, Pratt & Whitney's executive director for mobility and diverse engine programs. "Our unique experience with the B-52, coupled with our expertise integrating commercial engines onto military applications, will deliver a low-risk, high-performance engine to power the Stratofortress fleet through 2050.” GE Aviation will put forward the CF34-10 and Passport engines, spokesman David Wilson said. “GE is the only company to have been involved in re-engining U.S. Air Force aircraft three times over,” he said. “Add in our deep experience powering six strategic bombers, entrenched support of air combat and the reverence we have for the role we play in protecting this country, and GE is the clear partner to ensure the B-52 is ready at all times for mission critical.” Rolls-Royce intends to offer its F130 engine, the company confirmed. “Rolls-Royce is excited to move to the proposal stage of the campaign and ready to demonstrate that the Rolls-Royce F130 engine is the perfect fit for the B-52,” Craig McVay, senior vice president for Rolls-Royce Defense, said in a statement. “The F130 is a highly reliable and proven engine which is already in commercial production. Our team is focused and energized, and eager to compete for the B-52 Commercial Engine Replacement Program and provide the best possible solution for the U.S. Air Force and the key missions of the B-52 weapon system.” The Air Force plans to operate the B-52 into the 2050s and sees new commercial engines as a way to reduce fuel burn and the time it takes to maintain the bomber. Last year, B-52 maintainers at Barksdale Air Force Base, Louisiana, told Defense News that modern engines would make it easier for crews to diagnose problems and make needed repairs. “I would like to know if I need to take that aircraft down out of the schedule and give it a new engine ahead of time,” said Lt. Col. Tiffany Arnold, 2nd Maintenance Squadron commander. “We could prioritize, we could understand the patterns of the engines in a way that we could maintain them better. And hopefully the new motor, whoever designs it, will have a shorter mean time between failure, and we can fly them longer.” https://www.defensenews.com/air/2020/05/20/the-air-force-launches-a-contest-to-replace-the-b-52s-engine/

  Turkey’s ‘chronic engine problem’ is harming defense projects, warn officials

  By: Burak Ege Bekdil ANKARA, Turkey — Turkey's inability to produce a fully indigenous engine is harming some of the country's otherwise successful domestic defense programs, according to industry and government officials. “We had it 15 years ago, we had it 10 years ago and we are still having it,” said a former defense industry chief. “It's our chronic engine problem.” A government procurement official agreed, telling Defense News that “at best the problem causes major delays, and at worst it can be an existential threat [to programs].” The Altay, a multibillion-dollar program for the production of Turkey's first indigenous tank, has long been delayed due to difficulties surrounding the engine and transmission used to power the new-generation tank. BMC, a Turkish-Qatari joint venture that in 2018 won the serial production contract for the Altay, said in October 2020 that the tank would be fielded within 24 months. The original target was to have the Altay in the field this year 2020. Today, procurement officials and industry sources say even 2022 is an optimistic deadline. Western countries with power pack technology, particularly Germany, have been reluctant to share technology or sell to Turkey for political reasons. “Lack of a feasible power pack [engine and transmission] is depriving the program of any sensible progress,” noted an industry source. Turkey also needs an engine for the new-generation TF-X fighter jet as well as indigenous helicopter models in the making. At the center of these engine efforts is Tusas Engine Industries, a state-controlled engine maker. TEI announced June 19 that it successfully tested its locally made TJ300 miniature turbojet engine, which the company produced for medium-range anti-ship missiles. The engine features a thrust rating of 1.3 kilonewtons. Company officials say the TJ300 engine's more advanced, future versions could power larger anti-ship cruise missiles and land-attack cruise missiles. Turkey hopes to power its anti-ship and land-attack cruise missiles with locally developed engines. “The effort is about ending dependency on imported designs,” a TEI official said. Turkey currently imports miniature air-breathing engines from Microturbo — a unit of French company Safran — to power its domestically developed cruise missiles. Separately, Turkey's Kale Group is developing a larger, albeit miniature turbojet engine called the KTJ-3200. It has a 3.2-kilonewton thrust rating, and will power the Atmaca and SOM missile systems. On a much bigger scale, Kale Group has ambitions to develop an engine to power the TF-X. In 2017, Kale Group and British company Rolls-Royce launched a joint venture to develop aircraft engines for Turkey, initially targeting the TF-X. But the £100 million (U.S. $124 million) deal was effectively put on hold due to uncertainties over technology transfer. In December, Turkish Foreign Minister Mevlüt Çavusoğlu said the government is keen to revive talks with Rolls-Royce. When asked for an update on negotiations, a Rolls-Royce spokesperson told Defense News: “We submitted an engine co-development proposal to Turkey, but the customer has not elected to pursue this to date.” A year before the Kale Group-Rolls-Royce partnership, Turkish Aerospace Industries — a sister company of TEI — signed a $125 million heads of agreement with U.K.-based firm BAE Systems to collaborate on the first development phase of the TF-X. Turkey originally planned to fly the TF-X in 2023, but aerospace officials are now eyeing 2025 at the earliest. TEI is also developing the TS1400, a turboshaft engine it intends to power the T625 Gökbey, a utility and transport helicopter developed and built by TAI. The Gökbey currently flies with the CTS-800A turboshaft engine supplied by Light Helicopter Turbine Engine Company, a joint venture between American firm Honeywell and Rolls-Royce. The Gökbey made its maiden flight in September. TEI says it successfully tested the “core” of its TS1400 turboshaft engine and plans to deliver the prototype to TAI in late 2020. But analysts remain cautious. “These efforts may eventually fail to materialize without meaningful foreign know-how,” said a London-based Turkey specialist. “Or they may come at costs not viable for mass production.” Andrew Chuter in London contributed to this report. https://www.defensenews.com/industry/techwatch/2020/06/26/turkeys-chronic-engine-problem-is-harming-defense-projects-warn-officials/
