ASDS is an 65 foot mini-submarine, which rides attached to the top of a much larger Los Angeles class submarine. It has increased range, speed, and capacity over the current SEAL Delivery Vehicle which is an open, wet submersible, that transports SEALs in scuba gear, exposing them longer to the elements. The ASDS mini-submarine is operated by a crew of two and can carry eight SEAL team members. The vessel is connected to the host ship via a watertight hatch, and has a sophisticated sonar and a hyperbaric recompression chamber. USN photo # N-0000X-005, courtesy of news.navy.mil.
