- W39 abstract "The Mark 39 nuclear bomb and W39 nuclear warhead were versions of an American thermonuclear weapon, which were in service from 1957 to 1966.The Mark 39 design was a thermonuclear bomb (see Teller-Ulam design) and had a yield of 3.8 megatons. The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the same design). The Mark 15 was the first lightweight US thermonuclear bomb.The W39 warhead is 35 inches in diameter and 106 inches long, with a weight of 6,230 to 6,400 pounds. It was used on the SM-62 Snark missile, Redstone IRBM missile, and in the B-58 Hustler weapons pod.Two Mark 39 nuclear bombs were carried by a B-52 Stratofortress that broke up in the air and crashed near Goldsboro, North Carolina on January 24, 1961. According to Parker F. Jones, a supervisor of nuclear safety at Sandia National Laboratories, in a 1969 report that was declassified in 2013, the Mark 39 bomb had four safety mechanisms, one of which was not effective in the air. On one of the bombs involved, two more safety mechanisms were "rendered ineffective by aircraft breakup." As a result, Jones noted that the bomb was preventing from detonating only by the fourth mechanism, a simple "ready-safe" electric switch.".
