From the Document: "The Navy wants to begin procuring a new class of nuclear-powered attack submarine (SSN), called the Next-Generation Attack Submarine or SSN(X), in FY2031. The SSN(X) would be the successor to the Virginia-class SSN design, which the Navy has been procuring since FY1998. The Navy's proposed FY2022 budget requested $98.0 million in research and development funding for the SSN(X) program. [...] The Navy's proposed FY2022 budget requested $98.0 million in research and development funding for the SSN(X) program, including $29.8 million in Project 2368 (SSN[X] Class Submarine Development) within Program Element (PE) 0604850N (SSN[X]), which is line 154 in the Navy's FY2022 research and development account, and $68.1 million in Project 2370 (Next Generation Fast Attack Nuclear Propulsion Development) within PE 0603570N (Advanced Nuclear Power Systems), which is line 48. The joint explanatory statement for the HASC-SASC-negotiated proposal for the FY2022 National Defense Authorization Act (S. 1605) that was released on December 7, 2021, recommends approving the Navy's research and development funding requests for the SSN(X) program. The joint explanatory statement states: 'We believe that efforts to develop any form of alternative naval nuclear fuel system should ensure that such a system can be produced in a manner that will not reduce vessel capability, increase expense, or reduce operational availability as a result of refueling requirements,' and directs the Administrator for Nuclear Security to submit a report on activities conducted using FY2021 funding for development of an advanced naval nuclear fuel system based on LEU."
