Redesigned Brakes and Wheels Are on the Way for B-52 Bomber B-52H Stratofortresses from the 2nd Bomb Wing line up on the runway as part of a readiness exercise at Barksdale Air Force Base, La., Oct. 14, 2020. (U.S. Air Force/Senior Airman Tessa B. Corrick) 8 Apr 2021 Military.com | By Oriana Pawlyk With the U.S. Air Force's plan to keep the long-range B-52 Stratofortress flying into the 2050s, the venerable, Cold War-era bomber is going to need new brakes and wheels. The service selected Collins Aerospace, part of Raytheon Technologies, to design and develop a new wheel and brake for the bomber, and to retrofit 77 new brake and wheel combinations, including spares provisioning, the company said Wednesday. To increase the brakes' wear life, the company will use its carbon heat sink material known as DURACARB, which provides "increased thermal absorption" as the aircraft slows and brakes on the runway during a landing, explained Matthew Maurer, vice president and general manager of military programs, landing and mechanical systems.

The new brake-wheel combination "is going to allow for longer intervals between brake overhauls or longer intervals between inspections on the wheels," he added. "We anticipate being through the design and development phase and supporting flight testing by 2023, and then [retrofitting] the fleet by 2026." Air Force maintainers will work alongside engineers to learn how to change or update the system; Maurer said the service will run the schedule, choosing which bombers will receive the first upgrades. Collins did not publicize the cost of the contract award. The Air Force already uses the DURACARB system on the C-130 Hercules, F-16 Fighting Falcon and F-15 Eagle. The new wheel is rated for 12,500 miles, a major upgrade from just 1,500 miles for the B-52's current brake system, Maurer said. The Air Force is also nearing a decision on procuring new B-52 engines. The service has been pushing for a major engine overhaul for the bomber fleet for years. In 2017, an engine fell off a B-52 while the aircraft was flying over North Dakota. Each aircraft currently has eight Pratt & Whitney TF33-P-3/103 turbofan engines. Three companies are in the running to replace the engines: Pratt & Whitney, which is a Raytheon Technologies' company; General Electric; and Rolls-Royce. But while the Air Force issued a request for proposal, or RFP, last May, it has delayed issuing a contract award. In 2019, lawmakers insisted that service officials nail down contract specifics before they would provide funding. That year, the Air Force estimated it would spend around $1.3 billion through 2024 on work related to the re-engining. The RFP stipulated a total of 608 engines for its 76-aircraft fleet. While officials have said there has been no delay, the service has still not committed to an official award date. Gen. Tim Ray, head of Air Force Global Strike Command, said in February that it's "too early" to determine whether the award will be announced in June -- the original projected contract announcement time frame. "We should have this summer the answers back from the competitors to be considered," Ray said during the Air Force Association's virtual Aerospace Warfare Symposium. "And so then, from that process, we'll go from there. "This is not being [dragged] out," he said, as reported by Defense News. "It is on time. In fact, it is several years early." He said that digital prototyping, or simulating parts via computer models, has begun on the companies' side, which could shorten the engine production time. The planes are among the oldest in the Air Force. Three generations of airmen have flown the B-52 in combat, from Vietnam to Afghanistan; the final bomber rolled off the production line in 1962. The B-52 has been prominent in missions such as Operations Desert Storm and Iraqi Freedom, as well as the fight against the Islamic State in Iraq and Syria. Affectionately known as Big Ugly Fat Fellow, or BUFF, B-52s have been on rotation for the service's Bomber Task Force, or BTF, missions over the past year, part of the Pentagon's larger "dynamic force employment" strategy. As part of the BTFs, the service sends out two to four bombers for units to test how nimbly they can move from place to place. -- Oriana Pawlyk can be reached at oriana.pawlyk@military.com.

About time they upgrade the brakes. Hopefully they'll be able to eliminate the drag chute along with this upgrade.
I loaded nukes on the Buff in 1969 at Griffiss AFB hard to believe they are still flying must all be H models now.
They really need to add Thrust Reversers to these Old Girls, brakes and "Chute" ain't enough for some of the shorter runways we are using, and it would sure cut costs in tire replacements, something that has ALWAYS been an issue with the BUFF's!
They reengined the KC-135 with big turbofans and didn't add reversers, but did upgrade the brakes. The original brakes were shit. Had to call the fire department on many occasions with hot brakes.
I'd swag that as not going to happen, the wings are not designed to be loaded that way. Another scheme that might work would be a jato type thing on the fuselage. Same sort of problem with structural loading, but might be easier to solve.
Ah, yes. The BUFF. 1940's tech at its best. The USAF was pushing for a re-engine when I was still active, and I retired in 1994.... They just don't build 'en like they used to....
You'd think, with the current missile and drone technology, that B-52s would be retired. Guess there's still a role for them. Cool bombers nonetheless.
We sure enjoyed the carpet bombing in Iraq the two times I was there! Seeing Old Smokey come screaming over the desert at just a couple hundred feet and unload a mile long string of nastyness on the enemy, it was epic! Almost as cool was looking up and just barely seeing a grey shape with a bunch of contrails coming off it and a few seconds later a #2000 pound JADAM detonates out in front of you just a mile or so away! That gets your heart rate up a bit!
pulled all the bomb racks when the launchers came on >>> your count is about right - last iron bomb B52 run was in Northern Iraq against Saddam's Guard - later the US found their tanks buried under feet of sand - everybody thought the massacre of the Kwait retreat was something ....
Tracking buff at near supersonic speeds is one thing, really pretty simple. BUT once the missiles escape the dump, the problem for the defense becomes, um, larger.
