The B-52 Stratofortress bomber came into service in 1952 and is still flying. President Trump stated “your grandfather’ may have flown the plane. This was factually true as there is at least one family with three generations of B-52 crew members. The Air Force currently flies the B-52H model and the planes are older than the aircrews. The possible re-engine of the planes is being evaluated and with over a 50 year combat experience to draw from, the design needs are well vetted for a re-engine modernization program.
