After two decades, work was completed in December on a program to extend the life of the W76 nuclear warhead, the Y-12 National Security Complex said on Monday.

That ended a decade of work to extend the service life of the original warhead design by 40 years, Y-12 said.

“This warhead plays a vital role in maintaining the nation’s credible nuclear deterrent,” said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

The Life Extension Program, or LEP, is for the W76-1 warhead. The W76-1 is a refurbished W76-0 warhead. The W76-0 warhead is a submarine-launched ballistic missile system that was first introduced into the stockpile for the U.S. Navy in 1978. The warhead is deployed with Trident II D5 missiles on Ohio-class nuclear ballistic missile submarines. [Read more…]

WASHINGTON, D.C.—The National Nuclear Security Administration said last week that it had reached the halfway point in the production phase of the W76-1 warhead Life Extension Program, or LEP. An event held at the Pantex Plant in Amarillo, Texas, underscored NNSA’s commitment to meeting the U.S. Navy’s requirements for the W76-1.

Gen. Frank G. Klotz, U.S. Department of Energy under secretary for nuclear security and NNSA administrator, was on hand to personally thank the men and women of Pantex who helped achieve the production milestone.

“The W76-1 Life Extension Program is one of several steps we must take as a nation to ensure that America’s smaller nuclear arsenal remains safe, secure, and effective,” Klotz said. “The highly skilled Pantex team will continue to play an indispensable role in protecting the security of the United States, as well as our allies and partners, for many years to come. For that reason, it’s imperative that we continue to invest in the people and in the infrastructure needed to carry out that important, enduring task.” [Read more…]
