CODE E10 - MARITIME MISSION SYSTEMS DIVISION SEAL Delivery Vehicle (SDV) NSWC PCD provides the design technical capability and serves as In-Service Engineering Agent and Sustainment Activity for the SDV MK8 MOD1. The NSWC PCD Team completed two SDV MK8 MOD1 restricted overhauls and two SDV MK8 MOD1D customized vehicle “grooms” supporting cold-water testing and Propulsion Power Interface installations for the Naval Special Warfare customer. The team also completed one SDV MK8 MOD1 restricted overhaul for the Foreign Military Sales customer. Several major Engineering Change Proposals were initiated resulting in fielding of Power Port Optimization, Underwater Doppler Velocity Log obsolescence resolutions, and Control Display Unit software using an open architecture convention called “NEO,” which supports plugand-play network systems capabilities. Because the SDV MK8 MOD1 is expected to be fielded through 2022 or beyond, the NSWC PCD SDV team continues to address SDV obsolescence issues and provide options for technology insertions. Noteworthy efforts included SDV Obsolescence Mitigation and Architecture Cleanup, and completion of a feasibility study funded by the Foreign Military Sales customer for a 1-meter vehicle extension to the SDV MK8 MOD1 as a sustainable future capability.
Dry Combat Submersible (DCS) NSWC PCD provides engineering services and required planning for United States Special Operations Command and Naval Special Warfare Dry Combat Submersible acquisition and testing initiatives. NSWC PCD provided on-site systems engineering support at MacDill Air Force Base, Tampa, FL, and engineering test planning activities at NSWC PCD to host engineering characterization of two DCS technology demonstration vehicles. NSWC PCD completed testing documentation for the DCS Button 5.60, whose testing was deferred from 2015 into 2016, and completed draft testing documentation for the DCS S351 in anticipation of tests commencing in February 2016. NSWC PCD also provided engineering coordination of successful technology demonstrations using the DCS S301 submersible vehicle with MK89 Silver-Zinc battery modules, a Valence Technology lithium battery system, and an electro-optic sensor labeled “Gumball.”
MK18 MOD2 Unmanned Undersea Vehicle Family of Systems The MK18 MOD2 completed Office of the Secretary of Defense FastLane fielding of unmanned undersea vehicle system capabilities to Commander Fifth Fleet (COMFIFTHFLEET); Autonomous Topographic Large Area Survey modules completed delivery in January 2015 and Small Synthetic Aperture Minehunting modules completed delivery in March 2015. Custody of four MK18 MOD2 systems, including all mission support equipment and spares, were transferred from contractors to COMFIFTHFLEET, effectively transferring all operations and capabilities to the U.S. Navy. The MK18 MOD2 was designated an Acquisition Category ACAT IV-M in August 2015. The NSWC PCD Team established new hardware and software sustainment activities in addition to existing technology development, project and systems engineering activities to support the NAVSEA Program Manager. An Engineering Change Proposal for Precision Underwater Mapping Array, Build One, was approved and delivered to COMFIFTHFLEET in June 2015, and Build Two was beta-delivered in August 2015. MK18 future capability initiatives also participated in the ONR-sponsored demonstration of unmanned undersea vehicle technologies at NAS Patuxent River in August and September 2015.
