The SSN(X) or Next-Generation Attack Submarine program of the United States Navy aims to develop a new class of nuclear-powered attack submarines to succeed the Virginia and Seawolf classes. The SSN(X) program remains in the early stages of development and no official details have been released about its design or capabilities.

An SSN is a nuclear-powered general-purpose attack submarine. SSN is the US Navy hull classification symbol for such vessels; the SS (as 'Ship Submersible') denotes a submarine [1] and the N denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, [2] though navies use other terms.
