The W69 was a United States nuclear warhead used in AGM-69 SRAM Short-Range Attack Missiles. It was designed in the early 1970s and entered the U.S. stockpile in 1972. It remained in service until 1992, with the last units being retired in 1996. About 1,500 were produced. By 1999, all the warhead's various parts had been dismantled. The high explosives were removed from around the plutonium pits at the Pantex Plant and the pits were put into secure storage. Non-nuclear components were taken to the Savannah River Site and the National Security Campus. The canned subassemblies were moved to Y-12 National Security Complex, where recovery of the uranium began in 2012 and was completed in 2016.[1] The W69 design was one of many derived from the B61 nuclear bomb design.
