Sized to accommodate from one to six SEALs traveling inside, most SDV’s are free-flooding meaning the soldiers are submerged in water, often for hours at a time, using their SCUBA tank, or onboard oxygen to breathe.
Now, the Navy has also developed a dry version of the SDV.
These vehicles are made out of fiberglass and non-ferrous materials, so that their magnetic and acoustic footprints are kept to a minimum to avoid detection.
They are equipped with Doppler navigation, docking systems, and sonar to guide the SDV back to the host submarine after the SEALs have been delivered to the location of the mission.
Due to their clandestine design the vehicles are reportedly capable of carrying out attack missions, and underwater charges housed in large cargo holds can be deployed to attach to a ship’s hull for timed or remote detonation.
