SEAL DELIVERY VEHICLE (SDV)
BRIEFING: The Mk 8 Mod 1 SDV is a manned wet-submersible
vehicle used to deliver Navy SEALs and their equipment to mission areas. The crew operates and navigates the submerged SDV
while using underwater breathing apparatus for life support.
The SDV, developed by the Naval Surface Warfare Center,
Panama City, Fla., is battery-powered and equipped with
propulsion, navigation, communication and life-support equipment. It is capable of delivering several fully equipped SEALs to
a mission area, loitering, retrieving the SEALs and returning
while remaining submerged.
The Mk 8 Mod 1 SDV, delivered to Naval Special Warfare forces
in 1996, has increased range, speed, capacity and maintainability
over previously operational SDVs. A fleet modernization for all
SDVs was completed in September 2006, including increased diver
air capacity, improved diver communications, satellite communications capability, reduction of signal acquisition time for the Global
Positioning System and installation of a Windows-based computer.
The SDV eventually will be replaced by the Shallow-Water
Combat Submersible, a 10,000-pound vehicle that will carry six
or more SEALs.
