    Navy Starting Work on New SSN(X) Nuclear Attack Submarine - USNI News

    The U.S. Navy is starting early preparation work to design a new nuclear attack submarine to replace the Virginia-class boats (SSN-774) in the 2030s. The new attack boat would become operational in 2044 after the last Block VII Virginias are built.

    “The long range shipbuilding plan is for a new SSN authorized in 2034 in lieu of the eighth block of Virginia-class,” Rear Adm. Dave Johnson, Naval Sea Systems Command’s program executive officer for submarines told the Naval Submarine League Symposium in Falls Church, Va., on Thursday
    “2034 may seem far off, but the design research community needs to take action now.”
    There will likely be an analysis of alternative for the new submarine—which has tentatively dubbed SSN(X) — in about 10 years or 2024.

    That, Johnson said, leaves nine years to identify, design and demonstrate the new technologies the new attack boat will need.

    Johnson said that he has formed a small team to work on a five-year plan to begin to do some of that work. The team will consult with industry and will identify the threat environment and technologies the submarine will need to operate against in the 2050 plus timeframe, Johnson said.

    One of the areas Johnson has already indentified as critical for SSN(X) is integration with off-board systems. Vice Adm. Mike Connor, Commander of Submarine Force, Atlantic (COMSUBLANT), said that future submarine weapons for both the Virginia and the future SSN(X) would be networked extremely long-ranged weapons.

    Some of the concepts include a new prototype torpedo propulsion system from Pennsylvania State University — a torpedo could hit targets that could hit targets more than 200 nautical miles away.

    “I’m not sure I’m mentally prepared to employ a 200-mile torpedo, but I’m going to put some thought into that,” Connor said.

    Connor said that while an attack boat like the Virginia or SSN(X) might launch a torpedo, the targeting data might come from another platform.

    Those other platforms could include an aircraft like an unmanned aerial vehicle launched from the submarine or something like a Boeing P-8 Poseidon. In fact, in the submarine might not even guide the weapon to its target in the terminal phase of the engagement, Connor said.

    There are few certainties in life, save for a few exceptions. Life is uncertain, but death is inevitable. Taxes are bound to happen. And the other certainty is that even when the US has yet to finish building something, like the remaining Virginia waiting to be built, they are already in the process of planning its successor. The new torpedo would be an interesting concept, but a data link or relay would have to be used at such long ranges to guide the torpedo effectively. With that much distance to cover, too many opportunities to defeat the torpedo exist and that ultimately lessens the rationality of the concept. Using air or sea assets as a relay on route to a target would be an optional guidance method to lessen a failed track. Expect drone launch and recovery (Both UAV and UUVs) capabilities to be added as well to the mandatory requirements in addition to lockout facilities for special forces, vertical launch tubes and reduced emissions.

    We live in the Modern era, everything worth inventing has been Invented. Give your brains a break Americans, allow us to catch up :P
