SSN(X): The Submarine That Makes Russian and Chinese Admirals Sweat

In an answer to a rising threat from China and its movements toward Taiwan and Japan, plus belligerence toward its other neighbors, the U.S. Navy has a framework for increasing the number of ships and submarines over the coming decades. The Chief of Naval Operations has a “NAVPLAN” or navigation plan to add new vessels to the fleet by 2045. This is a roadmap released in late July for 373 manned ships and 150 unmanned ships for an estimated total of 523. What does this mean for the next-generation SSN(X) attack submarine? Will the Navy keep or lose interest in the program for its new “Apex Predator” boat?  

SSN(X) Is In the Navy’s Playbook

So far it’s steady as she goes for the “Next Generation Attack Submarine” SSN(X). The new sub is an integral part of the NAVPLAN, and the Navy sees it as a feature for “large diameter payload boats” that can launch hypersonic missiles – a mission that is expected to be right up SSN(X)’s alley. Large diameter refers to the future launch tubes that will be wider to accommodate hypersonic weapons. SSN(X) could replace the four Ohio-class guided-missile submarines that feature the older Tomahawk cruise missile that has been in service since 1983. 

Need to Maintain a Steady Rate of Funding

SSN(X) will need research and development funding each year until it is introduced and undergoes sea trials for full-fledged production by the mid-2030s. So far, naval advocacy on Capitol Hill has worked. The nuclear-powered SSN(X) will receive an R&D appropriation of $144 million in the FY23 National Defense Authorization Act.

Large Numbers Planned in Navy’s Roadmap 

According to the specific text of the NAVPLAN, “Nuclear-powered fast-attack and large payload submarines to hold adversaries at risk in both contested seas and open oceans. We will continue to build the Virginia-class at a sustainable rate while developing the SSN(X) with a capacity goal of 66.” This is interesting because the “66” number is not specified as to whether that means a combination of Virginia-class boats combined with the SSN(X) that will equal 66 vessels. If this is the case, it appears the Navy has plans to produce several SSN(X) subs.

Much to Like About Its Capabilities

All subs aim to be fast in order to run silent and deep. The SSN(X) is no exception and will have the speed and acoustic superiority to outclass any enemy submarine. The SSN(X) will be “smart” and able to communicate with a full spectrum of naval vessels including a large number of unmanned ships the Navy expects to deploy by 2045. The SSN(X) could even launch drones that have sonar and sensors to collect intelligence, surveillance, and reconnaissance information. These capabilities do not come cheap, and each SSN(X) is expected to cost $6 billion. Alternatively, Virginia-class subs cost $3.6 billion.

Best of the Best Submarine Programs

The Congressional Research Service says the Navy wants the SSN(X) to incorporate the speed and payload of the Navy’s fast and heavily armed Seawolf-class (SSN-21) SSN design, the acoustic quietness and sensors of the Virginia-class design, and the operational availability and service life of the Columbia-class design.

SSN(X) has a long way to go until its produced in numbers. Hopefully, the Navy will ultimately order two a year in the mid-2030s. Cost is always a factor, and the sub will need champions in the Pentagon and Congress, plus an enthused Chief of Naval Operations before the concept becomes a full Apex Predator. This boat is exciting and will be a way to counter the Chinese as Beijing orders more aircraft carriers, submarines, and surface ships as both countries race to see who can have the most powerful Navy.

    The US Navy is stupidly putting all its eggs in one basket with big expensive nuclear submarines. When what it needs is dozens of small utility subs for amphibious support, cargo, and drone support in contested waters where surface ships dare not sail. The oceans are large, ships and subs are slow, and more coverage is needed.

    Hypersonic missiles are expensive prestigious political boondoggles (slower than ballistic missiles), which don’t add any demonstrated combat power, and who’s only utility is lining defense contractor’s pockets and the procurement officers who will be going to work for them.

    The US Marines are the only force that is adapting to the “mature precision strike regime” while the Pentagon seems intent on getting thousands of American troops killed in obsolete weapon systems (surface ships, non-stealthy combat aircraft, Tanks, APC, AFV, armored vehicles, etc.).

    History has shown the transition to any higher evolution of weapons results in a massive loss of life (machinegun). Smart weapons are the biggest evolution in weapons ever. America must learn from the past and take action to avoid the loss of American lives, anything else is irresponsible.

    The relentless pursue of one upmanship, when it is obvious, the race can’t be won by any of the competing parties. The era of US military hegemon is already over as China and Russia are technologically capable of matching US in different aspects of military development. In fact, it would be in the interest of mankind to negotiate arms reduction based on that mutual respect, and peaceful co-existence of superpowers that can be bring economic development for their own people. Arm race only benefit the military cindutrial complex at a great expense to the ordinary citizens!

    They are great proposals from consecrated teachers.
