Advanced SEAL Delivery System (ASDS) was a midget submarine operated by the United States Navy and United States Special Operations Command designed to provide stealthy submerged transportation for special operations forces (primarily United States Navy SEALs) from the decks of nuclear submarines for primary use as an insertion platform for covert and clandestine operations. The program was abandoned after the only prototype example of the class was damaged beyond economic repair in an accidental fire.
