The W76-1 warhead is placed on the re-entry vehicle for the submarine-launched Trident II D5 ballistic missile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Production on the W76-1 started in Sept. 2008; the modernization effort not only extends the service life of the weapons by about 20 years, but comes with added safety features, requiring what NNSA head <a href=\"https:\/\/www.defensenews.com\/outlook\/2018\/12\/10\/nnsa-administrator-strengthening-america-through-nuclear-security\/\" target=\"_blank\">Lisa Gordon-Hagerty<\/a> called \u201csignificant modifications\u201d to the design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cToday is a shining example of the crucial role NNSA plays in enhancing our nation\u2019s nuclear security,\u201d Gordon-Hagerty said at a ceremony Wednesday in Texas.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/defensenews\/smr\/2018\/11\/02\/heres-when-all-of-americas-new-nuclear-warhead-designs-will-be-active-and-how-much-theyll-cost\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"216\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/lawrence-livermore-nnsa-facility.jpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">Here\u2019s when all of America\u2019s new nuclear warhead designs will be active \u2014 and how much they\u2019ll cost<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">America will be spending a lot on nuclear weapons in the coming years.

Gordon-Hagerty acknowledged at much, saying the program\u2019s completion is a sign the agency can \u201cdevelop, execute and complete\u201d future life extensions and modifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, there may still be work to do for the W76 going forward, thanks to the Trump administration\u2019s decision to seek a low-yield variant of the weapon, <a href=\"https:\/\/www.defensenews.com\/space\/2018\/02\/02\/the-us-could-be-getting-2-new-nuclear-capabilities-here-are-the-details\/\" target=\"_blank\">dubbed the W76-2<\/a>. Production for that design could be done as soon as next year or go through FY24, depending on funding, but its future is unclear; democrats oppose the warhead design, and Rep. <a href=\"https:\/\/www.defensenews.com\/congress\/2018\/11\/14\/smith-aims-to-scrap-trumps-nuclear-weapons-policy\/\" target=\"_blank\">Adam Smith of Washington<\/a>, the new chairman of the House Armed Services Committee, has said he will <a href=\"https:\/\/www.defensenews.com\/smr\/defense-news-conference\/2018\/09\/05\/cuts-to-nuclear-spending-and-oversight-of-socom-what-to-expect-from-a-democratic-hasc\/\">look to kill the development<\/a> and use those funds elsewhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For now, Gordon-Hagerty said, the NNSA is \u201ctrack to meet DoD requirements\u201d on the W76-2.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The next nuclear warhead program to <a href=\"https:\/\/www.defensenews.com\/space\/2018\/10\/01\/americas-newest-nuclear-gravity-bomb-completes-design-review\/\" target=_blank>hit a major milestone<\/a> should be the B61-12, a new version of America\u2019s nuclear gravity bomb which will replace the B61-3, -4, -7 and -10 variants. That program is slated to deliver its first production unit in FY20 and complete production by FY24.
