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.”

Valerie Insinna Months after the Air Force gave Raytheon the axe on the Three-Dimensional Expeditionary Long-Range Radar (3DELRR) program, the service has tapped three new companies to work on next-generation ground-based radars. Lockheed Martin, Northrop Grumman and Australian firm CEA Technologies were each awarded $500,000 on May 8 for a 3DELRR rapid prototyping effort known as “SpeedDealer,” the Air Force announced Monday. 3DELRR will replace the legacy AN/TPS-75 radar used to detect and track aerial targets flying at long distances. Raytheon had beaten Northrop and Lockheed for the contract in 2017 after a protracted competition that included multiple protests over the award. After schedule delays and technical challenges mounted, the Air Force announced in January that it was concluding its work with Raytheon on the program. Instead, the service would seek out off-the-shelf options from industry that could be fielded faster. “Each award provides $500,000 for the companies to demonstrate their radar system's capabilities, maintenance concepts and radar performance against operationally-relevant targets and conditions, no later than the end of September,” the Air Force said in a statement. The service would then determine whether a prototype is ready for integration or production, with additional contracts potentially awarded by the end of 2020. Initial operational capability of a production-ready radar could occur as early as fiscal year 2024, the service said. Despite a global pandemic, the program is already moving at a fast pace. After holding an industry day in February, the Air Force released a solicitation for the 3DELRR program on March 2, said Lt. Col. Matthew Judge, materiel leader. The three companies were selected less than a month from when industry proposals were due on April 15. “We are not starting over; this is not a new development contract,” said Col. Michael Harm, 3DELRR's senior materiel leader. “Through the information presented during our industry day and received in the companies' response to the solicitation, we were able to confirm that production-ready systems can be demonstrated this year.” Judge added: “We are excited to see what these three systems can do.” Lockheed and Northrop's work will be funded under a contracting mechanism known as an “other transaction authority,” which is typically used for prototype projects. As a foreign company, CEA has been granted a Foreign Comparative Test project award, the service said in a statement. Northrop Grumman will demonstrate its solution this summer, said Mike Meaney, the company's vice president for land and maritime sensors. “We are confident that our solution meets the Air Force's needs and is the most affordable, low-risk, and validated system available,” he said. “With successful completion of test demonstrations, a hot full-rate production line and opportunities for capability growth, we are confident that the Northrop Grumman solution is uniquely positioned to fulfill the Air Force 3DELRR mission need." https://www.c4isrnet.com/industry/2020/05/11/these-three-companies-got-money-to-prototype-new-ground-based-radars-for-the-us-air-force/
