Teledyne Brown Engineering Inc. is awarded a contract, worth around $41.4 million, to produce MK11 Shallow Water Combat Submersibles (SWCS) for the U.S. Navy.
The company will also provide related engineering services under the firm-fixed price, cost and cost-plus-fixed-fee contract awarded by the U.S. Navy’s Naval Sea Systems Command (NAVSEA).
The contract work will be performed in Huntsville, Alabama, and is expected to be completed by December 2022. This contract includes options which, if exercised, would bring the cumulative value of this contract to around $178.2 million and be complete by December 2023.
Shallow Water Combat Submersible (SWCS)
The Shallow Water Combat Submersible (SWCS) is a manned submersible and a type of swimmer delivery vehicle (SDV) which will deliver U.S. Navy SEALs and their equipment for special operations missions.
SWCS, designated as Mark 11 SDV, will replace the current Mark 8 SEAL Delivery Vehicle (SDV). It is also requested by the Royal Navy’s Special Boat Service (SBS), which currently operates 3 SDV’s.
SWCS will be deployable from surface ships, land, and Dry Deck Shelters (DDS) on submarines. The SWCS is 12 inches (30 cm) longer and 6 inches (15 cm) taller than its predecessor, the Mark 8 SDV. This will require modifying the DDS to accommodate it. The U.S. Navy plans to lengthen the DDS by 50 inches (1.3 m) and triple its weight capacity.
The SWCS will also be about 4,000 pounds (1.8 t) heavier than its predecessor and will have more advanced computer systems and better navigation, with new systems including an electro-optical periscope, sonar detectors, and automatic docking.
Teledyne Brown Engineering was awarded the contract to develop the SWCS in 2011. The $383 million contract provides for the construction of 10 submersibles, the first of which is expected to enter service is 2018. The Columbia Group, which builds and provides support for the existing Mark 8 SEAL Delivery Vehicle, also works on the program.
