USAF selects F130 turbofan for B-52 re-engine program Citat:The U.S. Air Force announced on Sept. 24 that it has given Rolls-Royce a $500 million contract to buy 608 commercial engines for the B-52 re-engine program.
The work is expected to be completed by Sept. 23, 2038 and will be built in the company’s facility in Indianapolis.
The indefinite-delivery/indefinite-quantity contract is worth $2.6 billion if all options are exercised.
The F130 is the military variant of the BR725, which is currently used on the E-11 and C-37.

Citat:Because of the B-52's massive side surface area and low-slung wing, crosswind landings are especially challenging. With this issue in mind, Boeing engineers built the B-52's main tandem landing gear with a genius feature — they swivel. The details of this feature were kept secret for years after the Stratofortress's introduction into service.
The pilot simply dials in the runway's heading via a rotary dial in the cockpit and the gear will remain properly aligned with a selected compass heading throughout the jet's approach. This way the pilot can fly the approach crabbed into the wind, with its wings level, all the way down to touchdown and rollout. This capability is especially relevant as the B-52's wingtips and outrigger landing gear are far from the fuselage's centerline and hang nearly as low as the jet's lower fuselage edge. Just a couple of degrees of roll to the left or to the right could result in a wing dipping multiple feet. As a result, using ailerons to sideslip or even de-crab the jet before touchdown could end in a wing-strike catastrophe. Thus B-52 pilots fly intensely crabbed crosswind approaches, sometimes looking out the cockpit's side windows at the runway, all the way through touchdown and rollout.
