Construction and design

Thach was laid down on 6 March 1981 by the Todd Pacific Shipyards, Los Angeles Division, San Pedro, California; launched on 18 December 1982; sponsored by Mrs. Madalyn J. Thach, widow of the namesake; and commissioned on 17 March 1984 at Long Beach, Cmdr. Dale H. Moses in command.

Thach's mission was to provide anti-air, anti-surface, and anti-submarine protection for carrier battle groups, naval expeditionary forces, replenishment groups, convoys, and other military and merchant shipping. The new direction for the naval service remained focused on the ability to project power from the sea in the critical littoral regions for the world.

Success in the warfare environment of the 1990s and beyond required thorough evaluation, rapid decision-making and almost instantaneous response to any postulated threat. The systems aboard Thach were designed to meet these demanding and dynamic prerequisites, and to do so with minimum human interface. The Sikorsky SH-60 Seahawk's video data link system brought state-of-the-art computer technology to the warfare arena, as well as integrating sensors and weapons to provide a total offensive and defensive weapons system.
In addition, computers controlled and monitored the gas turbine engines (the same engines installed on DC-10 aircraft) and electrical generators. Digital electronic logic circuits and remotely operated valves were monitored in Central Control Station which initiated engine start and resulted in a "ready to go" status in less than ten minutes.
Service history
In 1986, the ship, part of Destroyer Squadron 21, deployed to the Western Pacific as part of a battleship battle group led by New Jersey.
In late 2006 while deployed to the Southern Pacific, Thach caught fire as she attempted to put out a fire on a drug smuggling ship.
Cmdr. Steven R. Rasmussen, a 1988 graduate of the Naval Academy who took command of the ship 6 October 2006, was relieved of command on 28 February 2008 by the commander of Destroyer Squadron 7.
Fate
Thach was decommissioned at Naval Base San Diego on 1 November 2013, Cmdr. Hans E. Lynch in command. The ship was homeported in San Diego and was part of Destroyer Squadron 23. She was sunk on July, 14, 2016 during the major naval exercise RIMPAC 2016. The hulk was sunk fifty-five miles north off the coast of Kauai. Despite being hit by at least four antiship missiles, bombs, Hellfire missiles and a torpedo it took twelve hours to sink.
Crest
Like all heraldic Navy insignias, Thach's crest has special meaning. The blue and gold colors are traditionally associated with the Navy; blue for the sea and gold for excellence. The pair of wings in the upper crest refers to Admiral Thach’s contributions to naval aviation as a pilot and leader. One of the contributions to naval aviation as a pilot and leader was his invention of the "Thach Weave," symbolized by the interlaced silver chevrons. This two-plane fighter tactic, used to cover each other from enemy fighters, is still used by fighter aircraft today.
The three-pronged trident is shown pointing down from the sky, symbolizing naval aviation’s role of projecting power from the sky and the sea. The three tines of the trident also represent Fight Squadron Three, the unit Admiral Thach commanded during early Pacific carrier battles in World War II. The cross within its outlined border and the wreath refer to Admiral Thach’s first and second awards of the Navy Cross and the Navy Distinguished Service Medal.
The anchor in the center of the insignia focused attention on the nautical nature of both Admiral Thach’s service to his country. The ship’s motto, “Ready and Able,” was representative of Admiral Thach’s preparation and success.
