An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

The W87 design includes all modern safety features, including insensitive high explosives LX-17 and PBX-9502 (primary component TATB), a fire resistant pit, and advanced arming and fuzing safety features. The original yield of the W87 was 300 kilotons of TNT, but has the announced ability to be upgraded to a yield of 475 kilotons, presumably by using more HEU in the fusion secondary stage tamper. It is not known if that upgrade was completely tested or merely designed and ready to implement.

  • The W87 design includes all modern safety features, including insensitive high explosives LX-17 and PBX-9502 (primary component TATB), a fire resistant pit, and advanced arming and fuzing safety features. The original yield of the W87 was 300 kilotons of TNT, but has the announced ability to be upgraded to a yield of 475 kilotons, presumably by using more HEU in the fusion secondary stage tamper. It is not known if that upgrade was completely tested or merely designed and ready to implement. The exact dimensions of the W87 are classified, but it fits inside the Mk. 21 reentry vehicle, which is a cone with base diameter of 22 inches (55 cm) and a length of 69 inches (175 cm). The weight is believed to be between 440 and 600 pounds (200 and 270 kilograms).
