Defense: The Last of the Bombers

The U.S. has quit building manned bombers. In Fort Worth, Texas, the Air Force recently took delivery of the last of 100 Convair B58 Hustler supersonic bombers it had ordered. Two days before, the last of 744 B-52H strategic bombers was turned over to the U.S.A.F. in Wichita, Kans., by Boeing. North American’s 2,000-m.p.h. Valkyrie, once designated the B-70, is still under development, but its classification has been changed from bomber to ”reconnaissance-strike” plane.
