NNSA is extending the life of the W80-1 warhead through the W80-4 Life Extension Program (LEP) for use in the U.S. Air Force’s (USAF) Long Range Standoff (LRSO) weapon. Together, the W80-4 and LRSO will help ensure the long-term effectiveness of the bomber leg of the Nation’s nuclear triad against more sophisticated defenses.

2020年7月24日 · The National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy (DOE), has identified a range of risks facing the W80-4 nuclear warhead life extension program (LEP)—including risks related to developing new technologies and manufacturing processes as well as reestablishing dormant production ...

2015年10月15日 · The goal of the W80-4 Life Extension Program (LEP) is refurbishing the W80 warhead with replacement components for aging technology and components that have limited lifespans. Sandia’s California site is responsible for development of non-nuclear components and subsystems and for systems integration.

As with the W80-4 LEP, the planned replacement program for the W78 represents an important opportunity to extend the warhead’s service life and incorporate modern safety and security features. The W80-4 is the first U.S. warhead designed for use with a new carrier since nuclear testing ended in 1992.
