B-29 "Very Heavy" bomber units were redesignated "Medium" with the introduction of the B-36 Peacemaker into the inventory in 1948, with some units transitioning to the B-36/RB-36 beginning in 1949. The B-50 Superfortress, an advanced version of the B-29 was also introduced in 1949. SAC deployed non nuclear-capable B-29 groups to Far East Air Forces in 1950 to conduct strategic bombardment missions over the skies of North Korea, however the aircraft was made obsolete by the development of Soviet jet-powered interceptors such as the MiG-15. The B-29 soldiered on for a more few years in the strategic bombardment role, but by 1955 was replaced by the B-47 Stratojet medium bomber. In 1950, conversions of B-29s to KB-29P aerial tankers began to reach SAC squadrons. KB-29s were in service with SAC until being replaced by the KC-97 Stratofreighter (which was itself based on the B-29) by 1955. 1st Fighter Wing, (B-29, 1949) March AFB, California Assigned to Headquarters 1st FW while attached to 22d Bombardment Wing 5th Strategic Reconnaissance Wing (B-29, 1949; RB-29, 1949–1951; KB-29 1949–1951) Activated in July 1949 Mountain Home AFB, Idaho Tail Code: Circle-X 23d Strategic Reconnaissance Squadron 31st Strategic Reconnaissance Squadron 72d Strategic Reconnaissance Squadron Replaced by RB-36D Peacemaker in 1951 6th Bombardment Wing (B-29, 1951–1952) Activated in January 1951 Walker
