W62
From Wikipedia, the free encyclopedia
The W62 is an American thermonuclear warhead designed in the late 1960s and manufactured from 1970 to 1976, used on some Minuteman III ICBMs and still in service as of early 2006.
The exact dimensions of the W62 are unknown, but it fits within the Mark-12 reentry vehicle which is 22 inches in diameter and 72 inches long. The weight of a fully loaded Mark-12 is 800 pounds; the weight of the W62 is stated as 253 lb.
The yield of the W62 is 170 kilotons.
A total of 1,725 W62 warheads have been produced during its production run. Most of those are now retired, with 610 units still in service on board 200 Minuteman III ICBMs (3 per missile, plus some spares).
