USS Greenville The Los Angeles-class sub USS Greenville (SSN 772) is shown off Pearl Harbor on July 1, 2003, after finishing tests for the Advanced SEAL Delivery System (ASDS). ASDS is a 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. The SDV is an open wet submersible that requires the SEALs to wear scuba gear, exposing them to the elements for long periods. The ASDS mini-submarine is operated by a crew of two and can carry eight SEAL team members. It is connected to the host ship via a watertight hatch, and has a sophisticated sonar and a hyperbaric recompression chamber.
