On 28 July 1947, the 93d Bombardment Wing, (Very Heavy) was established and maintained combat readiness for global strategic bombardment, flying the Boeing B-29 Superfortress. The wing was later redesignated as the 93d Bombardment Wing (Medium) as it was not chosen to be reequipped with the Convair B-36 Peacemaker, but remained with the B-29. In 1949, the wing received its first B-50 Superfortress aircraft, an improved version of the B-29. It began operations overseas with the deployment of its tactical force to RAF Mildenhall, England (July 1950 – January 1951) in response to communist aggression on the Korean peninsula. Meanwhile, the 93d Air Refueling Squadron was activated on 1 March 1949, equipped with the KB-29P (a B-29 bomber modified with a refueling boom).
