Operation Chrome Dome was a United States Air Force Cold War-era mission from 1960 to 1968 in which B-52 strategic bomber aircraft armed with thermonuclear weapons remained on continuous airborne alert and flew routes to points on the Soviet Union's border.[1]


During the Cold War, General Thomas S. Power initiated a program whereby B-52s performed airborne-alert duty under code names such as Head Start, Chrome Dome, Hard Head, Round Robin,[2] and Operation Giant Lance. Bombers loitered near points outside the Soviet Union to provide rapid first-strike or retaliation capability in case of nuclear war.[3][4]

Primary mission[edit]

The missions in 1964 involved a B-52D that left Sheppard Air Force Base, Texas, and flew across the United States to New England and headed out to the Atlantic Ocean. The aircraft refueled over the Atlantic heading north to and around Newfoundland. The bomber changed course and flew northwesterly over Baffin Bay towards Thule Air Base, Greenland. It then flew west across Queen Elizabeth Islands of Canada. Continuing to Alaska, it refueled over the Pacific Ocean, again heading southeast, and returned to Sheppard AFB.[5]

By 1966, three separate missions were being flown: one east over the Atlantic and the Mediterranean, another north to Baffin Bay, and a third over Alaska.
