In the aftermath of arms control treaties, some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines are being converted to become long range conventional strike and special operations SSGN “Tactical Tridents.” Four ultra-stealthy Ohio-class SSBNs are having their 24 Trident II D-5 nuclear ballistic missiles removed and replaced with up to 154 Tomahawk cruise missiles. The USA is also adding accommodation for 66-102 special forces troops, special attachments for new Advanced SEAL Delivery System (ASDS) or older Seal Delivery Vehicle (SDV) “mini-subs,” and a mission control center. In future, the SSGNs may also carry UUV underwater robotic vehicles and even UAVs for aerial operations.

STS International in Berkeley Springs, WV won a $23.3 million cost-plus-fixed-fee contract for operational capabilities for the surface and subsurface surveillance system (Quad-S). Quad S is a multifunction surveillance system that can be used in both military expeditionary operations and homeland security missions.

STS will perform the work in Tampa, FL and expects to complete it by September 2014. This contract was competitively procured via Navy Electronic Commerce Online and FedBizOpps websites, with 3 proposals received by the Naval Surface Warfare Center (NAVSEA) Panama City Division in Florida (N61331-09-C-0020).

Alion Science and Technology in McLean, VA received a task order (N00178-04-D-4066) from the US Navy valued at $48.5 million to research, design, develop, prototype, integrate and test a new torpedo detection system in conjunction with the Navy’s anti-torpedo countermeasure technology effort.

The task order, awarded under the Naval Undersea Warfare Center Division Newport’s Seaport-Enhanced (Seaport-e) contract, supports the Naval Sea Systems (NAVSEA) Undersea Defensive Warfare Systems Program Office with anti-torpedo torpedo defensive system (ATTDS) torpedo detection, classification and localization (TDCL) technology.

Seaport-e is a $5.3 billion multiple-award umbrella contract that lets the US Navy use an integrated approach to contracting for support services.

The ATTDS TDCL is a project [PDF] within the Navy’s Surface Ship Torpedo Defense (SSTD) program…

The UK Ministry of Defence has signed a GBP 369.5 million (about $615 million), 10-year contract with BAE Systems Insyte to support and maintain the Royal Navy’s light Sting Ray and heavy Spearfish torpedoes. The availability-based Torpedoes Capability Contract consolidates 11 separate contracts into one, and will see BAE Systems and the MOD’s DE&S Weapons Operating Centre working together as “Team Torpedoes.” It covers all aspects of support and maintenance, as well as Spearfish development and upgrade work. BAE says that they expect this partnering approach to lead to savings of about GBP 65 million, or 20% over the traditional support approach.

The TCC agreement will directly secure around 120 posts at BAES Insyte in Portsmouth, as well as subcontractors who will receive about 33% of the contract’s total value. Sub-contractors and torpedo details follow:

Mk 48: Before and After
(click for full sequence)

The Mk-48 is the standard heavyweight torpedo used by the US military, and is mounted primarily on submarines. Surface ships use the smaller Mk46 or Mk50. The Mk-54, in contrast, stemmed from the need for a smaller, lighter, and cost effective advanced torpedo – one that could be dropped from helicopters, planes, and smaller ships. In recent years, the US has moved to modernize and maintain its Mk-48 inventory; the Mk-54 also requires servicing and spares.

These contracts are being issued under a total enterprise partnership between Raytheon and the US Navy called Team Torpedo, dedicated to meeting the needs of U.S. and allied naval fleets. Team Torpedo combines Raytheon’s manufacturing, design engineering, and support services expertise with the systems engineering and testing capabilities of Naval Undersea Warfare Center (NUWC) operations in Newport, RI, and Keyport, WA. Total announced awards under that consolidated torpedo contract since its announcement on June 22, 2004 have now risen to $261.9 million, issued on behalf of the US and Royal Australian navies.

DID has the complete set of contracts below… plus more details regarding the torpedos involved, and the answer to the question “what the heck is CBASS standard”? The latest development is contract involving the Mk54…

AP-3C over Darwin
(click to view full)

In November 2005, the Australian Government, Tenix Defence and Eurocopter subsidiary Australian Aerospace (AA) have signed the P3 Accord Master Agreement to provide capability upgrades and Through Life Support (TLS) for the Royal Australian Air Force (RAAF) AP-3C Orion maritime patrol and anti-submarine warfare aircraft. The three parties have established a Joint Management Office (JMO) to supervise all Accord activities under a unique risk-sharing contractual arrangement. The JMO will develop and implement all RAAF AP-3C capability upgrades and TLS solutions through to the aircraft’s planned withdrawal date – at which point it will likely be replaced by the 737-based AP-8A MMA.

The combined value of the TLS and block upgrades to the aircraft is expected to be more than A$ 1 billion, and the project is moving on to a new phase – even as some of the efforts that led to the most recent announcement win Australian awards…

Vietnam has reportedly agreed in principle to a deal with Russia for 6 of its diesel-electric Kilo/ Project 636 Class fast attack submarines. The deal’s value is reported to be around $1.8 billion, and the SSKs will be built at Admiralty Shipyards in St. Petersburg. In addition to submarines, reports indicate that the Vietnamese Navy will receive new heavyweight torpedoes and missiles.

Aside from Thyssen’s U209 family of submarines, the Kilo Class are the world’s most widely exported subs. They are known for a level of quietness that is significantly better than many other Russian submarines, and have been produced in the Project 636 and Project 877EKM “Improved Kilo” variants. Countries operating or ordering these submarines include Russia, Algeria, China, India, Indonesia, Iran, Poland, and Romania.

There have been rumors that Vietnam owns 2 ex-Yugoslav mini-submarines for use in commando operations, but the Vietnamese People’s Navy doesn’t own any full size submarines that can take on enemy subs and ships. China’s recent display of naval might is only part of the mosaic influencing Vietnam’s decisions in this matter…

Sting Ray concept
(click to view full)

BAE recently announced that the Norwegian Defence Logistics Organisation has selected BAE Systems Sting Ray MOD 1 lightweight torpedo for its Norwegian Antisubmarine Torpedo (NAT) program following an international competition, and issued a GBP 99 million (EUR 136.1M / $145M) contract. These pump-jet propelled, autonomous active-homing 324mm torpedoes will arm Norway’s new Fridtjof Nansen Class AEGIS frigates, NH90 NFH Anti Submarine Warfare helicopters, and its P-3C Orion maritime patrol planes.

“Lightweight” torpedoes are light only in comparison to their huge 533mm ship-killing counterparts, like the submarine-launched American Mk48 torpedo and BAE’s own Spearfish. Submarines are easier to sink than enemy destroyers, however, which allows warhead and torpedo size to be reduced for carriage and launch from smaller surface ship torpedo tubes, maritime patrol aircraft, and anti-submarine helicopters.

This is the first export success for the upgraded Stingray MOD 1…

MU90 Eurotorp

In December 2005, “Beyond Armaris: Thales “Buys” Minority Stake in DCN” covered the government-prodded merger of Thales naval business with state-owned DCN, to create DCNS. That agreement excluded some naval items like electronics, but it did include Thales’ 24% share in Eurotorp, the European lightweight torpedo consortium that was officially founded in 1993 as a joint venture between DCN International (26%), Thomson-CSF (now Thales, 24%) and Whitehead (now Finmeccanica, 50%).

The DCNS transaction was not concluded until March 2007, and now the Eurotorp consortium has taken the next step by creating a more wide-ranging set of joint ventures in underwater weapons systems. The longer-term goal remains European integration, and the 3 CEOs have said they would consider opening the alliance to other European players at some point….
