W87 warhead design, nuclear deterrent. You asked us to examine plans for the W87-1 warhead. The W87 is an American thermonuclear missile warhead formerly deployed on the LGM-118A Peacekeeper ("MX") ICBM. It was designed for use on the Peacekeeper (MX) ICBM. It is hardened against nuclear effects, and has enhanced safety features. This meticulous understanding of weapons physics, engineering, materials science, and manufacturing processes gives the Laboratory’s W87-1 team the confidence to design and deliver a safe, secure, effective, and fully modernized nuclear warhead that meets requirements. nuclear weapons were distinguished by Mark (MK) numbers, derived from the British system for designating aircraft. 2 days ago · The publicly stated plan previously has been load each missile with a single W87-1 warhead. Each variation was The W87-1 Modification Program changes that. Sep 1, 2001 · The W87 warhead belongs to the newest missile warhead family, sharing a design similar to the W88. Relearning to design, engineer, and produce a warhead presents a tremendous challenge, but we are working side-by- side with our partners to deliver for the nation and transform the Nuclear Security Enterprise in multiple critical areas. S. The term “warhead-type” is used to denote a population of weapons with the same design. It combines a relatively high yield with increased accuracy to make it an effective hard target kill weapon. It is usually expressed as a TNT equivalent, the standardized equivalent mass of Throughout the history of nuclear weapons development, the United States has produced families of warheads based on a single-warhead design. For example, the B61 bomb has had 12 variations over time. The warhead is named the W87-1 to reflect that it has a similar primary design to the W87-0 and will fly in a similar reentry vehicle. ”. For the W87, Livermore and Sandia scientists and engineers developed and certified the engineering design and worked closely with NNSA production facilities to ensure a cost-effective design and ease of manufacture. Significant enough differences between a bomb or warhead variant, per direction from NNSA, result in further identification as a modification (Mod) to an existing design. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated. Figure 4. 1 is a comprehensive list of warhead types and their descriptions. Weapons in the current force structure include B61, W76, W78, W80, B83, W87, and W88. NNSA plans to newly manufacture the entire warhead, including the two major nuclear components, called the primary and secondary, using facilities it is modernizing or repurposing. arsenal. That effort enhanced the structural integrity of the warhead and extended its life by 30 years. The W87 design includes all modern safety features, including the insensitive high explosives LX-17 and PBX-9502 (primary component TATB), a fire-resistant pit, and advanced arming and fuzing safety features. With a yield of 300-475 kilotons, the W87 combines advanced thermonuclear design with enhanced safety and security features, making it one of the most sophisticated nuclear weapons in the U. 1 The earliest U. Mar 8, 2019 · By replacing the legacy W78, the W87-1 will maintain continuity for the ground-based leg of the U. 50 MX missiles were built, each carrying up to 10 W87 warheads in multiple independently targetable reentry vehicles (MIRV), and were deployed from 1986 to 2005. Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.
