Boeing B-52D

 

The B-52D was an improved version of the B-52C with mostly minor changes incorporated into the aircraft systems. The ability to carry to bomb-bay mounted reconnaissance and observation pod was eliminated and the “D” model was used only as a bomber.

 

The B-52D was used in the Cold War operation known as “Chrome Dome” in which a number B-52s armed with nuclear bombs always airborne alert. The purpose of this was to deter a Russian nuclear attack by guaranteeing that a significant number of nuclear armed bombers would escape the attack and be readily available to deliver an immediate and devastating counter-attack.

 

B-52Ds were also used extensively in Southeast Asia beginning in the mid-1960s. Operating from Andersen Air Force Base, Guam, and later U-Tapao Royal Thai Air Base, the B-52 was a major component of many operations including Arc Light, Iron Hand, Rolling Thunder, Linebacker and Linebacker II.

 

Production of the B-52 series began in 1954 and continued until the last aircraft, a B-52H was delivered in October of 1962. The B-52D remained in service until 1983 when the last aircraft of the 7th Bomb Wing were retired.
