Pratt & Whitney remains confident that a TF33 upgrade package it is developing would keep the fuel-guzzling Boeing B-52 bomber, an eight-engine goliath, flying into 2040 and beyond.
The aircraft was introduced in 1952 and the later H-model that remains in service today is still powered by the original P&W TF33, which celebrated its 55th anniversary of first flight in March.
P&W military engines president Bennett Croswell told Flightglobal last year that some four-engine options had been considered by the US Air Force as part of a potential re-engining programme, but the effort was abandoned. Oil prices have also dropped considerably since then.

Other than for posturing, is the B-52 still even a viable aircraft in war time?
