SSN(X)

SSN(X) Navy is focused on the development of the SSN(X) Class Submarine to replace the VIRGINIA Class Submarine. The specific goals and objectives of this program element include conducting concept and technical studies, modeling and simulation efforts to support Analysis of Alternatives (AoA) and requirement decisions, technology research and development, and capabilities/requirement definition that supports program milestone deliverables. The program aims to evaluate a broad range of submarine designs, technologies, sensors, and combat system components required to produce an affordable platform which supports mission requirements. Additionally, the program seeks to increase testing efforts, improve stealth and payload capacity, and initiate research and development infrastructure studies and upgrades to ensure readiness for planned authorization in the mid-2030s.

The U.S. Navy's primary goal for the SSN(X) program element is to counter the growing threat posed by near-peer adversary competition for undersea supremacy. The program aims to provide greater speed, increased horizontal payload capacity, improved acoustic superiority and non-acoustic signatures, higher operational availability, and conduct full spectrum undersea warfare. To achieve these objectives, the program will continue trade studies, expand technical and concept development studies informed by the AoA, define submarine platform design trade space based on whole-ship concept risks, expand advanced technology initial development and assessments as informed by the AoA, initiate ship specification efforts, continue acquisition documentation in preparation for Gate 2 and Milestone A, conduct infrastructure and industrial base evaluation and planning to ensure activities are ready for SSN(X), and begin infrastructure evaluation and maintenance. The program also plans to utilize work requests for government warfare center initial concept and trade studies through FY 2025 to assist with requirements definition.
