Since it became operational in 1955, the B-52 has been the main long-range heavy bomber of the Strategic Air Command. Â It first flew on 15 April 1952. Â Nearly 750 B-52s were built when production ended in October 1963, 170 of which were D models. Â The Ds were modified to carry conventional bombs externally and later series had provisions for Hound Dog air-to-surface missiles and Quail decoy missiles.
The B-52 has set many records in its 50-plus years of service.  On 18 January 1957, three B-52Bs completed the world’s first non-stop round-the-world flight by jet aircraft, lasting 45 hours and 19 minutes with only three aerial refuelings en route.  It was also a B-52 that made the first airborne hydrogen bomb drop over Bikini Atoll on 21 May 1956.  In June 1965, B-52s entered combat when they began flying missions with conventional bombs in support of operations in Southeast Asia (SEA).  By August 1973, they had flown 126,615 combat sorties with 17 B-52s lost to enemy action.
B-52s were stationed at Robins AFB from 1961-1983 with the 19th Bomb Wing. Â The aircraft on display served in Southeast Asia in 1968 and again 1972-1973, flying numerous combat sorties with the 99th Bomb Wing from Andersen AB, Guam. Â Its last flight was 25 August 1983 when it was delivered to Robins AFB for display by the 7th Bomb Wing, Carswell AFB, Texas.
