USS Guitarro (SSN-665), a Sturgeon-class submarine, was the second ship of the United States Navy to be named for the guitarro, a ray of the guitarfish family.

Construction and commissioning[edit]

Keel-laying and launching[edit]

The contract to build Guitarro was awarded to Mare Island Naval Shipyard at Vallejo, California, on 18 December 1964 and her keel was laid down there on 9 December 1965. She was launched on 27 July 1968, sponsored by Mrs. John M. Taylor.

Sinking[edit]

Guitarro on the bottom of the Napa River after her accidental sinking at Mare Island Naval Shipyard at Vallejo, California, on 15 May 1969.

On 15 May 1969, Guitarro was moored in the Napa River at Mare Island Naval Shipyard while construction was still underway. At about 16:00, a civilian nuclear construction group began an instrument calibration assignment which required the filling of certain tanks, located aft of the ship's pivot point, with approximately five tons of water. Within 30 minutes, a different, non-nuclear civilian construction group began an assignment to bring Guitarro within a half-degree of trim; this entailed the adding of water to tanks forward of the ship's pivot point to overcome a reported two-degree up-bow attitude. Until shortly before 20:00, both groups continued to add water, unaware of each other's activities.

Twice between 16:30 and 20:00, a security watch advised the non-nuclear group that Guitarro was riding so low forward that the 1.5-foot-high (0.46 m) wakes of boats operating in the Napa River were sloshing into an uncovered manhole in the most forward and lowest portion of the ship's deck; these warnings went unheeded. At 19:45, the non-nuclear group stopped adding water to the ballast tanks and began to halt work for their meal break, leaving at 20:00. At 19:50, the nuclear group completed their calibrations and began to empty the tanks aft.

At 20:30, both the nuclear group, still aboard, and the non-nuclear group, returning from their break, noticed Guitarro taking a sudden down angle which put the forward hatches underwater. Massive flooding took place through several large open hatches. Efforts between 20:30 and 20:45 to close watertight doors and hatches were largely unsuccessful because lines and cables ran through the doors and hatches, preventing them from closing. At 20:55, Guitarro sank [1] earning her the nickname "Mare Island Mud Puppy".

Guitarro was refloated three days later, on 18 May 1969. Damages to her were estimated at between 15.2 million USD and 21.85 million USD.

Commissioning[edit]

Guitarro had been scheduled to be commissioned in January 1970, but repairs necessitated by her sinking dictated a 32-month delay. She finally was commissioned on 9 September 1972 with Commander Gordon Lange in command.

Service history[edit]

In the mid-to-late 1970s, Guitarro was stationed at Point Loma in San Diego, California, commanded by Alvin H. Pauole, followed by Scott Van Hoften. She was active at the time in the pre-operational testing of the new Tomahawk cruise missile, launching several of the missiles on a test range off the coast of Southern California.

Decommissioning and disposal[edit]

Guitarro was decommissioned on 29 May 1992 and stricken from the Naval Vessel Register the same day. Her scrapping via the Nuclear-Powered Ship and Submarine Recycling Program at Puget Sound Naval Shipyard in Bremerton, Washington, was completed on 18 October 1994.
