The B61-11, which entered service in 1997, is significantly different in form and function from other variants with a substantially reinforced outer shell, possibly with a depleted uranium penetrating nose section, and a rocket booster at the rear to help it penetrate down to underground facilities. There are reportedly less than 100 of these bombs in the stockpile.<\/p>\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\">\n<div class=\"wp-block-embed__wrapper\">\n<div class=\"twitter-tweet-container\">\n<div class=\"twitter-tweet twitter-tweet-rendered\"><iframe id=\"twitter-widget-0\" class=\"\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=thewarzonewire&amp;dnt=false&amp;embedId=twitter-widget-0&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1033888737426644993&amp;lang=en&amp;origin=https%3A%2F%2Fwww.twz.com%2Fair%2Fhints-at-more-b61-nuclear-bomb-variants-in-the-u-s-militarys-future&amp;sessionId=e45241891a5220f0bd3c66cc7feb8bb461c4b3cc&amp;siteScreenName=thewarzonewire&amp;theme=light&amp;widgetsVersion=2615f7e52b7e0%3A1702314776716&amp;width=550px\" frameborder=\"0\" scrolling=\"no\" allowfullscreen=\"allowfullscreen\" data-tweet-id=\"1033888737426644993\" data-mce-fragment=\"1\"><\/iframe><\/div>\n<\/div>\n<\/div>\n<\/figure>\n<p class=\"article-paragraph skip\">It had been suggested in the past that the B61-12 might be able to supplant the B61-11, as well as the much more powerful\u00a0<a href=\"https:\/\/www.twz.com\/38454\/imagine-following-this-on-the-highway-a-truckload-of-nuclear-training-bombs\" target=\"_blank\" rel=\"noreferrer noopener\">megaton class B83-1<\/a>, since the new bomb could be employed much more precisely.

It is also worth noting that it\u2019s not entirely clear how the tail-mounted guidance package found on the B61-12 and -13 could be blended together with the rocket booster at the rear of the B61-11, and a true successor to the latter bomb might have a substantially different overall design.<\/p>\n<p class=\"article-paragraph skip\">The U.S. military could also have an interest in pursuing other future B61 variants offering different capabilities, including ones focused on employment with lower yield settings.
