Mark 28 Thermonuclear Bomb The Mk-28 hydrogen bomb was first produced in 1958 and remained in service until the early 1990s. Aircraft carried a streamlined variant externally or non-streamlined version internally. Used by various fighter and bomber aircraft (F-100, F-104, F-105, B-47, B-52, B-66 and others), these weapons also armed Hound Dog and Mace missiles. The artifacts on exhibit are BDU-16/E training variants of the Mk-28 and are displayed on an MHU-7/M Bomb Lift Trailer. Click here to return to the Cold War Gallery.
