## Highlights

The Advanced SEAL Delivery System (ASDS) is a hybrid combatant submersible providing clandestine delivery and extraction of Navy SEALs and equipment in high-threat environments. The first ASDS has had significant performance issues and has cost, to date, over $885 million. In May 2006, Congress requested that GAO review ASDS. This report examines (1) how the Navy managed ASDS risks through its contracts and (2) the status of major technical issues and program restructuring.
