The USA’s Ohio/ Henry M. Jackson Class and Britain’s Vanguard Class SSBNs (i.e. nuclear missile submarines) will begin experiencing age-related risks by the late 2010s, and military programs of this type can easily take 15-20 years from concept to fielding. The Common Missile Compartment (CMC) sub-program will help to define one of the next-generation SSBN’s most important constraints.

CMC aims to define the missile tubes and accompanying systems that would be used to launch new ballistic missiles, successors to the current Trident II/ D5 missile fleet used by the USA and Britain. The new CMCs will reportedly carry just 12 launch tubes each, as opposed to the current Ohio SSBNs’ 24, or the Vanguard SSBNs’ 16. Key options under consideration include a widened diameter for each tube from 2.21m – 3.04m, and the potential for flexibility beyond nuclear missiles.

The USA needs new SSBN submarines. Their existing Ohio Class boats will begin to retire at a rate of 1 hull per year, beginning in 2027, as they reach the end of their 42-year operational lifetimes. Britain, meanwhile, relies on its Vanguard fleet for the entirety of its nuclear deterrent. Their alternative to replacement involves becoming a non-nuclear power. The first step in that replacement involves the new Common Missile Compartment and Advanced Launcher.

While CMC will define key constraints for America and Britain, it may also create opportunities. One is built-in: commonality with the USA’s SSBN (X) program, which is beginning to look at options for replacement of the Ohio class. The other is a flexibility opportunity. There is no question that the future Common Missile Compartment will be built around the nuclear deterrence mission, as its primary focus. That is unlikely to be its sole use, however, and it would not be surprising if some of those other potential uses ended up influencing the CMC’s design.

Converted Ohio class SSGNs, for instance, have already replaced nuclear missiles with American special forces, land attack missiles, and UAVs. In a similar and related vein, the Virginia Class Block III fast attack submarine replaces 12 vertical-launch cruise missile tubes with 2 Common Weapon Launcher (CWL) “six-shooters” that are derived from the SSGNs’ converted missile tubes. The size of those CWLs will allow these submarines to launch cruise missiles, UAVs, UUVs, and more from these same tubes.

Note that the USA and Britain aren’t alone in their pursuits. At present, both France and Russia are already working on successor sub-launched ballistic missile systems and submarines.

Nuclear missile submarines are a nation’s most strategic assets, because they are its most secure and certain deterrence option. One does not commit them casually, to any purpose. As key trends like cheaper sensors and the Robotic Revolution grind onward, however, the next 40 years will see the SSBNs’ environment change. SSBNs will need the flexibility to adapt. For the USA and Britain, the CMC needs to be part of that adaptation.

Jan 26/13: Electrical. TG Daily reports that the next American SSBNs will be doing away with their mechanical drivetrain, which connects the reactor turbines directly to the boat’s propellers. In order to make the boat quieter, and free up electricity for other functions, power from the reactor would flow into an all-ship electrical grid. Some of that power would be harnessed by electric motors connected to the shortened propeller shafts, and it would probably be more than the 20-25% available in more conventional nuclear designs.

This kind of “all-electric” system is becoming more and more common on naval surface ships, so its adaptation to next-generation submarines is unsurprising. Even so, the cramped, no-failure world of submarine design always adds new engineering challenges. The USN also plans to field its new SSBN submarines with reactors that don’t require mid-life refueling, something they’ve already accomplished on the Virginia Class fast attack boats.

Jan 17/13: Electric Boat Corp. in Groton, CT receives a $12.8 million cost-plus fixed-fee modification for continued CMC work, including materials and testing of the equipment that will manufacture CMCs for the USA’s Ohio Replacement Program.

Sept 24/12: Defending the program. US Navy Director, Undersea Warfare Rear Adm. Barry Bruner pens a blog post about the Ohio Class Replacement Program. He defends the Navy’s vision of 12 sub marines instead of 14, with 16 tubes each instead of 24, at a target cost of $FY10 4.9 billion per hull for boats 2-12. At the same time, he acknowledges that the existing SSBN force will have a problematic period, which will become very problematic if the replacement program suffers any significant delays:

“Because ship construction of the Ohio Replacement shifted from the year 2019 to 2021, there will be fewer than 12 SSBNs from 2029 to 2042 as the Ohio-class retires and Ohio replacement ships join the fleet. During this time frame no major SSBN overhauls are planned, and a force of 10 SSBNs will support current at-sea presence requirements. However, this provides a low margin to compensate for unforeseen issues that may result in reduced SSBN availability. The reduced SSBN availability during this timeframe reinforces the importance of remaining on schedule with the Ohio Replacement program to meet future strategic commitments. As the Ohio Replacement ships begin their mid-life overhauls in 2049, 12 SSBNs will be required to offset ships conducting planned maintenance.”

If the Ohio Class Replacement Program manages to come in on time, and anywhere close to its budget, it will be a very unusual example within recent US Navy shipbuilding programs. The higher-odds bet, unfortunately, is that the USA is headed for serious problems with the readiness of its SSBN deterrent.

Oct 18/11: No Virginia. The US Navy has reportedly shelved the idea of a Virginia Class SSBN variant (vid. July 20/11), in favor of a new and quieter SSBN design that will carry the CMC. The question is whether that stance can last, given the new design’s current estimated cost of $7 billion per boat. If those costs rise, or budgets shrink, that Navy may find itself with fewer submarine platform choices than it would like. AOL Defence

The US Navy’s Supervisor of Shipbuilding Conversion and Repair in Groton, CT manages the contract (N00024-09-C-2100).

July 20/11: Virginias? To date, the assumption in America has been that CMC would equip a newly designed SSBN submarine, and GD Electric Boat has been hiring with the idea in mind. Connecticut’s The Day now quotes vice-Adm. Cartwright, Vice-Chair of the Joint Chiefs of Staff, as saying that budget cuts may force the Navy to lengthen its Virginia Class attack submarine, in order to fit ballistic missile compartments and act as an SSBN.

By nature fast attack submarines tend to be less optimized for stealth than SSBNs, though the Virginia Class is said to be remarkable in that respect. A more challenging difference is the weight/ size gap. Ohio Class SSBNs are about 18,750 tons submerged. Britain’s Vanguard Class SSBNs are 17,800 tons, and France’s Triomphant Class SSBNs are 15,800 tons. In contrast, the basic Virginia Class is about 7,800 tons. Even with fewer missile tubes on board, finding a solution that offers an affordable extension, instead of a full submarine redesign that defeats the point of starting with the Virginia Class, will be challenging. The Day.

July 6/11: General Dynamics Electric Boat Corp. in Groton, CT receives a $15.8 million modification to previously awarded contract (N00024-09-C-2100) for continued engineering, technical services, concept studies, and design of a common missile compartment for the United Kingdom Successor SSBN and the Ohio replacement SSBN submarine.

Work will be performed in Groton, CT (93%); Quonset Point, RI (3%); Newport News, VA (2%); and Newport, RI (2%). Work is expected to be complete by December 2011. US Naval Sea Systems Command in Washington, DC manages the contract.

May 18/11: British go-ahead. Defence Secretary Dr Liam Fox announces government approval for the early phase of design to replace the existing Vanguard Class. The new submarines will be powered by a new nuclear propulsion system known as the Pressurised Water Reactor 3, which is more expensive but safer. The design phase as a whole could be worth up to GBP 3 billion.

The Initial Gate approval ensures that more detailed design work will be undertaken and long-lead items ordered, even though the main build decision for the submarines will not be taken until 2016. Under current plans, the first replacement submarine is expected in 2028. For all further coverage of Britain’s new submarines, see “New Nukes: Britain’s Next-Gen Missile Submarines“.
