Design ĭetails about the design have not been publicly released and are likely to change because the project is still in development.

Of that total, $361.6 million was requested for general class development (a 151% increase) and a further $183.1 million for nuclear propulsion (a 97% increase). įor FY2024, the Navy requested substantially more money totaling $544.7 million, a 130% increase over FY2023. As in 2021, the requested budget lines were included unchanged in the FY 2023 NDAA signed into law by President Biden in December 2022.

The Navy's FY2023 budget requests included $237.0 million, including $143.9 million for general class development and $93.1 million for its nuclear propulsion. The related budget lines (0603570N and 0604850N) were included unchanged in the FY 2022 National Defense Authorization Act signed into law by President Joe Biden in December 2021. The Navy's budget request for Fiscal Year 2022 included $98.0 million to continue research and development, including $29.8 million for general class development and $68.1 million for developing its nuclear propulsion. Over the next several years, the Navy conducted studies and analyses to determine the capabilities and requirements for the new submarines.

The United States Navy first publicly discussed the SSN(X) program in 2014, describing plans to complete analysis of the new design's needs by 2024 and to begin construction by 2034, with initial deployment in 2043 after the last of the planned Virginia-class submarines are put into service. Despite projected schedules, it is not yet clear when the SSN(X) program will be fully developed and deployed, but it is likely to be a major focus of the Navy's research and development efforts in the coming years. It is believed that the SSN(X) program will focus on improving stealth, sensor capabilities, and firepower to enable the new submarines to operate effectively in a variety of missions, including intelligence gathering, special operations, and anti-submarine warfare.Īlong with the Columbia-class ballistic missile submarine, the SSN(X) program is seen as a critical component of the Navy's future submarine force and is expected to play a key role in maintaining the United States' naval superiority in the coming decades. The SSN(X) program is expected to incorporate advanced technologies and capabilities to ensure that the new submarines will be able to meet the evolving challenges of the modern maritime environment. The SSN(X) program is still in the early stages of development and no official details have been released about its design or capabilities. The SSN(X) program, also known as the Next-Generation Attack Submarine program, is a United States Navy program to develop a class of nuclear attack submarines to succeed its Virginia-class and Seawolf-class attack submarines.
