Navy's Next Attack Submarine Will Be Wider And Based On The New Columbia Class Missile Boats
The SSN(X) design will be wider than the present Virginia class, offering improved capabilities and increased stealthiness underwater.
Does anyone have any thoughts on displacement, size and weapon load-out for the this prospective follow-on to the Virginia Class SSNs?
"Unlike the Virginia Class Submarine, which was designed for multi-mission dominance in the littoral, SSN(X) will be designed for greater transit speed under increased stealth conditions in all ocean environments, and carry a larger inventory of weapons and diverse payloads," the budget request continues. "While SSN(X) will be designed to retain multi-mission capability and sustained combat presence in denied waters, renewed priority of the anti-submarine warfare (ASW) mission against sophisticated threats in greater numbers will influence the design trade space."
"We do expect it will be a larger type of submarine, probably in the size class of the Columbia, but there’s not much more to tell than that. But we’re working with our Navy customer in what that would look like and how we could take that into production,” Rex Geveden said, according to USNI News. “It has the moniker SSN(X) until it gets a class name, and there’s some thought, discussion, and analysis. It would be the follow-on to the Virginia fast-attack submarine, and it would feather in sometime in the late 2030s."
