CMC Program Defining Future SSBN Launchers for UK, USA

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. Key options under consideration include a widened diameter for each tube from 2.21m – 3.04m, and the potential for flexibility beyond nuclear missiles.

Imperatives and Opportunities

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. In both cases, the first step involves a new Common Missile Compartment and Advanced Launcher for current and future nuclear missiles. Both countries have also taken the next step, and begun designing the submarines that will carry CMC.

The USA and Britain aren’t alone in their pursuits. At present, France, India, Russia, and China are all working on successor sub-launched ballistic missile systems and/or SSBN submarines.

CMC: Present and Future

The new CMC/AL assemblies are slated for production in blocks of 4 tubes, allowing each partner to tailor the total number of missile tubes to its final submarine design. Current American Ohio Class SSBNs have 24 tubes, but SSBN-X currently plans to reduce that to 16 tubes. Britain’s current Vanguard Class has 16 tubes, but the number of tubes in its Successor Class hasn’t been set yet.

While CMC will define key constraints for America and Britain, it may also create opportunities.

One is built-in: commonality between their respective launch systems makes it easier to share changes and advances.

The other opportunity is about flexibility. 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 replaced their 12 vertical-launch cruise missile tubes with 2 Common Weapon Launcher (CWL) “six-shooters” derived from the SSGNs’ converted missile tubes. The size of those CWLs allows Virginia Class Block III 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 big changes in the underwater environment. SSBNs will need the flexibility to adapt and leverage these changes if they intend to survive. For the USA and Britain, the CMC needs to be part of that adaptation.

Contracts and Key Events

Unless otherwise indicated, the The US Strategic Systems Programs in Washington, DC manages the contract.

April 7/14: Specifications. The US Navy has reportedly finalized the specifications for their new SSBNs. They’ll be about as long as the current Ohio Class, but with 8 fewer missile tubes (16 total). The submarines will have a new electric propulsion system, and the same kind of no-refuel reactor enjoyed by recent US boats.

The latest Navy figures reportedly estimate $110 million per boat per year in operating costs. Sources: USNI, “Navy Has Finalized Specifications for New Ohio-Replacement Boomer”.

March 31/14: GAO Report. The US GAO tables its “Assessments of Selected Weapon Programs“. Which is actually a review for 2013, plus time to compile and publish. With respect to SSBN-X, the numbers are very large: $95.103 billion total for 12 boats, split $11.718 billion RDT&E and $85.385 billion in procurement costs.

“The Navy has set initial configurations for areas including the torpedo room, bow, and stern. In 2014, the program expects to complete initial specifications, set ship length – a major milestone – and start detailed system descriptions and arrangements.”

Navy officials are trying to reduce costs for boats 2-12 from an estimated FY10$ 5.6 billion to FY10$ 4.9 billion, and one approach is to seek commonalities with the Virginia Class and the UK’s Successor SSBN. The CMC itself is already doing some of that.

Feb 28/14: Long-lead. GD Electric Boat Corp. in Groton, CT receives a $16 million cost-plus-fixed-fee modification to previously awarded contract for CMC missile tube long-lead-time materials. This contract combines purchases for the government of the United Kingdom (67%) and the US Navy (37%) under the Foreign Military Sales (FMS) Program.

All funds are committed immediately, using British FMS and USN FY 2014 RDT&E funds. Work will be performed in Groton, CT, and is scheduled to be complete by February 2016. The Supervisor of Shipbuilding Conversion and Repair in Groton, CT manages the contract (N00024-13-C-2128).

Jan 30/14: UUV launcher. A joint effort between the US Navy and General Dynamics Electric Boat is now testing a prototype Universal Launch and Recovery Module (ULRM) system that would launch and capture underwater drones from SSBN/SSGN vertical launch tubes, and from the Virginia Payload Module on forthcoming Virginia Class submarines. Diagrams show payloads up to a pair of Bluefin-21 (future SMCM mine countermeasures) UUVs, but the extend and launch method itself is adaptable to any new UUV that fits within the space.

This isn’t a development that touches the CMC directly, nor is it new. Indeed, engineer Steve Klinikowski’s idea was tabled in 2005, and a model was exhibited at DSEi 2011 in Britain. This article is particularly helpful in showing pictures of the mechanisms, and in confirming that ULRM has progressed to testing. If there was any doubt that the CMC’s tubes are likely to include payload options beyond nuclear missiles, those doubts are effectively removed. The time to contemplate those needs is right now, during the CMC’s design phase. Engineering.com Designer Edge, “Navy Begins Test of UUV Launch System” | Fox News, “Navy, Electric Boat test tube-launched underwater vehicle”.

Jan 28/14: DOT&E Testing Report. The Pentagon releases the FY 2013 Annual Report from its Office of the Director, Operational Test & Evaluation (DOT&E). CMC is included indirectly, as part of the “SSBN Ohio Class Replacement Program”.

SSBN-X is currently slated to include a new propulsor, a new electric drive system, and a degaussing system, all of which should make the new submarines harder to detect. The new nuclear reactor won’t require mid-life refueling, a long refit whose operational impact would have forced the USA to build 14 submarines instead of the planned 12. CMC provides the main weapons interface, and there’s currently a debate about whether to even give the SSBNs torpedo tubes. The Strategic Weapon System includes the Trident II D5 Life Extension missile, launcher, fire control, navigation systems, and associated support systems. Most of the SWS will be carried over from existing submarine classes, as will items like communications, sonar, and internal computer networks.

From September 2012 – July 2013, the Navy conducted an Early Operational Assessment (EOA) – an extensive review of Ohio and Ohio Replacement documentation to identify program risks, and a modeling and simulation study to compare the survivability of the existing and future submarine classes. The EOA did come up with some program risks, which are classified. The modeling and simulation was informative, but the acoustic and threat models need updating.

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 27/12: Integration. Lockheed Martin Space Systems Co. in Sunnyvale, CA receives a sole-source $51.6 million cost-plus-fixed-fee contract for engineering efforts to support next-generation SSBN programs. The firm was deemed to be the only company that could integrate the TRIDENT II Missile and Reentry Strategic Weapon System subsystems into the CMC, and design an updated missile service unit that will be compatible with both current and new submarine fleets. With options, this contract could rise to $52.2 million.

Work will be performed in Cape Canaveral, FL (50%); Sunnyvale, CA (34%); Syracuse, NY (10%); Magna, UT (2%); Washington, DC (1%); yet to be determined locations (2%); and other locations of less than 1% (1% TL); and will run until Dec 31/17 (N00030-12-C-0058).

Sept 24/12: Program Risk. 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

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.
