In October 1956, the Squadron was scheduled to convert to the Boeing B-52D Stratofortress retaining its designation. Events in the fall of 1956 would delay the conversion to B-52. The Suez Crisis and Eastern Europe conflicts required the wing and squadrons to remain operational, and were on "cocked ground alert" into the second week of December. The 327th was not operational from 5 February 1957 to 1 June 1957. 327th B-52 operations continued through February 1963, with training missions to improve and maintain proficiency, served on Ground Alert, and participated in a seven-month test of Airborne Alert missions during 3 March, to 6 October 1959. The airborne alert test would earn the second AFOUA.
