The service said that was because of an \u201cextended gap\u201d between the design programs for its Columbia-class submarine and the future SSN(X). <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The plans for the SSN(X) are ambitious. According to the Navy, the next-generation submarine \u201cwill provide greater speed, increased horizontal [i.e., torpedo room] payload capacity, improved signatures, flexibility\u201d and \u201cconduct full spectrum undersea warfare.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Autonomous systems are expected to be integrated into the SSN(X), which will reportedly model <a href=\"https:\/\/www.militarytimes.com\/naval\/2025\/04\/08\/us-navy-unveils-newest-virginia-class-fast-attack-submarine-uss-iowa\/\" target=\"_self\" rel=\"\" title=\"https:\/\/www.militarytimes.com\/naval\/2025\/04\/08\/us-navy-unveils-newest-virginia-class-fast-attack-submarine-uss-iowa\/\">the stealth capabilities of the Virginia class<\/a> and the rapid attack functions of the Seawolf class. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plans also call for the submarine to incorporate the flexibility and operational hardiness of the Columbia class, which itself is facing <a href=\"https:\/\/www.defensenews.com\/congress\/2025\/06\/24\/senators-concerned-with-navy-shipbuilding-delays-budget\/\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.defensenews.com\/congress\/2025\/06\/24\/senators-concerned-with-navy-shipbuilding-delays-budget\/\">staggering delays in development<\/a> and is currently projected to be delivered two years late in 2029. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Like the Columbia and Virginia classes, the vessel will be nuclear-powered. It is projected to be larger than the original design for the Virginia-class submarine, which is about 7,800 tons submerged, and possibly go over 10,100 tons. <\/p>\n\n\n\n<p
