Another $191M for General Dynamics. (Dec 21/11)
SSBNs are nuclear missile submarines. The USA’s Ohio/ Henry M. Jackson Class and Britain’s Vanguard Class SSBNs 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 and Britain are not alone in their pursuit. At present, both France and Russia are already working on successor sub-launched ballistic missile systems and submarines.
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.
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, and the CMC needs to be part of that adaptation.

Oct 18/11: 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
Oct 12/11: Electric Boat Corp. in Groton, CT receives a $7.1 million contract modification for preliminary design of an integrated tube and hull robotic welding system, as part of continued CMC procurement. New designs require new manufacturing techniques.

July 29/11: GD Electric Boat Corp. in Groton, CT receives a $16.2 million contract modification for CMC manufacturing and testing equipment, under the Ohio [Class] Replacement Program. The majority of the work will be performed in Groton, CT, and is scheduled to be complete by August 2013. The US Navy’s Supervisor of Shipbuilding Conversion and Repair in Groton, CT manages the contract (N00024-09-C-2100).
July 20/11: 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.

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.

May 18/11: British go-ahead. Defence Secretary Dr Liam Fox announces government approval hfor 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 Initial Gat 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. UK MoD | Defense News.
