USS Preserver (ARS-8) - Final Operations

Final Operations

Further Atlantic Ocean operations were followed by a Mediterranean deployment February–June 1964. In March 1968 Preserver pumped out of the bow of Liberian tanker SS Ocean Eagle a cargo of oil that threatened major pollution of San Juan, Puerto Rico, harbor. She also extinguished a fire aboard British merchant vessel SS Pizarro 11 April 1968 in San Juan Harbor. She then deployed to the Mediterranean 20 May 1968, returning to Little Creek, Virginia, 2 September. Into 1970 she continued to serve the Fleet as a salvage ship of Service Squadron 8 out of Little Creek, Virginia. In January 1986 she was tasked with leading the salvage and recovery efforts of the Space Shuttle Challenger disaster. During the transit to Port Canaveral the ship recovered the nose piece of the external fuel tank. The Preserver was on station through April 1986. On 7 March 1986, divers from the USS Preserver using sonar located what they believed to be the crew compartment (confirming it during a dive the next day) and commenced recovery operations for the fallen astronauts. John Devlin made the confirmation dive to verify that the wreckage was in fact the crew compartment. On 9 March, NASA announced the finding to the press. The ship received a Navy Unit Commendation for the operation. She was decommissioned on 30 September 1986, and recommisioned the following year.

After Hurricane Hugo, the USS Preserver was sent to Puerto Rico to aid in recovery of a sunken ship. The ship drove through Hugo en route to Guantanomo bay, Cuba where it picked up two barges loaded with telephone poles to take to Puerto Rico. It performed the first tandem tow in 40 years of US Naval history. The Preserver arrived safely at Puerto Rico and stayed there for nearly two months recovering a sunken vessel from the harbour.
