USS PIGION ASR-21

The USS Pigeon (ASR-21) was a Chanticleer-class submarine rescue ship commissioned by the United States Navy in 1968. Designed specifically to support deep-sea submarine rescue operations, she featured advanced diving and salvage equipment, including a twin-hull catamaran design that provided enhanced stability. USS Pigeon played a crucial role in supporting the Navy’s deep submergence rescue vehicles (DSRV), particularly during the Cold War era. She was decommissioned in 1992 after over two decades of service, having contributed significantly to submarine safety and rescue capabilities.
