USNS Neptune (ARC-2)

USNS Neptune (ARC-2) was a cable repair ship operated by the United States Navy, commissioned in 1953. Built on a C1-B cargo hull, Neptune's primary mission was the installation, maintenance, and repair of undersea cables crucial for naval communications and surveillance. Throughout the Cold War, Neptune played a vital role in laying and servicing submarine cables, including those associated with the Sound Surveillance System (SOSUS) used for anti-submarine warfare. The ship remained active until 2005, after which it was decommissioned and subsequently stricken from the Naval Vessel Register.
