As with many early US nuclear weapon designs, the fissile material or pit could be kept separately from the bomb and assembled into it during flight. This technology is known as In Flight
Insertion (IFI). The Mark 5 had an automatic IFI mechanism which could insert the pit into the center of the

The Mark 5 core and W5 warhead were 39 in (990 mm) in diameter and 76 in (1,930 mm) long; the total Mark 5 bomb had a diameter of 44 in (1,120 mm) and was 129–132 in (3,280–3,350 mm) long. The different versions of Mark 5 weighed 3,025–3,175 lb

The Mark 5 design was the first production
American nuclear weapon which, with a diameter of 39 in (990 mm), was significantly smaller than the 60 in (1,520 mm) diameter implosion system of the 1945

The Mark 5 and W5 were pure fission weapons. There were at least four basic models of core design used, and sub-variants with yields of 6, 16, 55, 60, 100, and 120

The Mark 5 was in service from 1952 to 1963. The W5 saw service from 1954 to 1963. Approximately 72 Mark 5 weapons were supplied for delivery by
