The B28, originally Mark 28, was a thermonuclear bomb carried by U.S. tactical fighter bombers, attack aircraft and bomber aircraft. From 1962 to 1972 under the NATO nuclear weapons sharing program, American B28s also equipped six Europe-based Canadian CF-104 squadrons known as the RCAF Nuclear Strike Force.

The Mk-28 hydrogen bomb, although first produced in 1958, remained an active item until 1991. It was designed to be carried by various fighter and bomber aircraft (F-100, F-104, F-105, B-47, B-52,...

The spotlight then shifted to the U.S. Navy to find and recover the B28. John P. Craven was head of the Navy's Deep Submersible Program in January 1966. After service during World War II on the battleship New Mexico (BB-40), he pursued a doctorate in ocean engineering before returning to the Navy as a civilian scientist working in submarine ...

The CR100 Receiver operated on the the frequency range 60-420 kHZ in two bands and 500kHZ-30MHz in four bands. The experimental model design was started in July, 1939 in order to provide the Royal Navy with a superior receiver. The experimental model was taken to Portsmouth for assessment in the spring of 1940.
