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

By:   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.”

    British next-generation fighter program taps new suppliers

    By: Andrew Chuter LONDON – A raft of top systems suppliers have been recruited to join the team leading Britain's development of the Tempest next-generation fighter aircraft. Bombardier in Northern Ireland, GKN, Martin Baker and Qinetiq, alongside the UK arms of Collins Aerospace, GE Aviation and Thales, have signed up to collaborate with the BAE Systems-led team working on the future air combat system, it was announced July 20 on what should have been the opening day of the Farnborough air show before Covid-19 caused the event's cancellation. At the same time as the announcement, Sweden's Saab revealed it was setting up a UK hub to potentially participate in future combat air systems work between the two nations. It's been almost two years to the day when the wraps were taken off a plastic mock-up of a Tempest fighter at the Farnborough show. The British revealed a BAE-led partnership, also involving Leonardo, MBDA, Rolls-Royce, that would begin investigating the technologies required for a future combat air system. Some $2.5 billion has so far been committed to the program. Now, just months before an outline business case to develop the program further is due to be delivered to the UK government, Team Tempest, as the industrial team is known, has signed up its first seven systems suppliers. With the first phase of the new partnerships signed, the companies will seek opportunities to join forces on established projects and developments with the core Team Tempest partners. More than 60 technology demonstration activities are currently underway on future combat air systems in the UK employing 1800 people – a number expected to grow to 2500 by the end of the year. In a statement, Defence Secretary Ben Wallace said he was “delighted seven more companies have joined this mission to work in collaboration with the MoD, under the Team Tempest banner. They will bring the ambition, invention and expertise that will deliver the breakthroughs we will depend on for decades to come.” The rising employment levels and increasing industrial support comes at a crucial time for a program which will pretty much dictate Britain's future position in the defense industrial world, given the air sector's importance to jobs, skills and exports here. An integrated defense, security and foreign policy review is underway led by Prime Minister Boris Johnson and his advisors, who are said to be skeptical of local industry's ability to deliver major programs on time and on budget and would rather buy defense equipment off the shelf. With Covid-19 pretty much emptying government coffers, launching a multibillion-dollar program like Tempest is likely to be an issue unless the British can sign up some major international partners to share the cost. Last year Italy and Sweden both signed up to investigate partnering with the UK on a future combat air system, and those studies are ongoing with neither country yet committing to the program. Sweden may not have yet committed to a partnership with the British and others, but its biggest defense company, Saab, announced July 20 it was to invest an initial $63 million setting up a new future combat air center with other initiatives in the UK. Saab leads Sweden's future combat air system industrial participation in cooperation with the defense ministry. Details of where and when the company will invest in the UK are sparse, but Micael Johansson, the president and CEO of Saab, said the move demonstrated the company's commitment to combat air development and the UK. “Saab took the decision to create a new future combat air system center so that we can further develop the close working relationship with the other FCAS industrial partners and the UK MoD. This emphasizes the importance of both FCAS and the United Kingdom to Saab's future,” said Johansson. The British have cast their net beyond Europe in the search for partners, with India and Japan also having held discussions about a potential tie-up on a future combat air system. Across the English channel France and Germany are together developing a new combat jet to a similar time frame. Attempts to merge the two European programs have so far failed, but that's not to say that post Covid-19 financial reality may not cause a potential tie-up to be revisited. Howard Wheeldon, of consultants Wheeldon Strategic Advisory, said that the British government knew was at stake in the development of a future combat air system. “Team Tempest is a very significant program for the UK. ... A partnership between government, military, industry and international partners all of whom are determined to succeed,” he said. “Industry, along with the RAF Rapid Capabilities Office, have already achieved a vast amount in a very short period of time. I, for one, am in no doubt that the government fully understands the importance of what ‘Team Tempest' means to the UK, not only to jobs and maintaining necessary skills, but in the potential that the development has in terms of future prosperity,” said Wheeldon. https://www.defensenews.com/global/europe/2020/07/20/british-next-generation-fighter-program-taps-new-suppliers

    USAF to buy more BACN

    by Gareth Jennings The US Air Force (USAF) plans to strengthen its Battlefield Airborne Communications Node (BACN) fleet, with a further six aircraft to be procured over the coming five years. With the fleet currently comprising three Bombardier Global 6000 regional jet-based E-11A (one of the original four was lost on operations in Afghanistan in 2020) and four Northrop Grumman RQ-4 Global Hawk unmanned aircraft, the service disclosed on 5 February that it plans to acquire a further six E-11As through to 2026. “In an effort to boost the fleet, the BACN Program Office is working to procure six E-11A aircraft over the next five years. The team has secured additional funding for the first aircraft, and contract negotiations on a purchase agreement are currently in progress,” the USAF said, adding that it expects to have a contract in place by the end of March. While the announcement said that all six aircraft would be delivered by the end of June, it appears from the previously stated timeline that ‘2026' was inadvertently omitted. News of the proposed boost to numbers came days after the USAF awarded Northrop Grumman USD3.6 billion for continued BACN operations, sustainment, and support. https://www.janes.com/defence-news/news-detail/usaf-to-buy-more-bacn
