USS Ingersoll (DD-990)

The USS Ingersoll (DD-990) was a Spruance-class destroyer in the United States Navy. Named for Vice Admiral Royal Rodney Ingersoll, Jr. and his father, Rear Admiral Royal Rodney Ingersoll, Sr., it was the second ship to bear that name.

Ingersoll was laid down by Ingalls Shipbuilding, Pascagoula, Mississippi on 30 June 1977, launched on 4 August 1979, and commissioned on 12 April 1980.

Throughout its service, Ingersoll conducted numerous deployments, participating in exercises and operations around the world. Some significant deployments included service in the Persian Gulf, and counter-narcotics operations in the Caribbean and Eastern Pacific. She earned several battle efficiency awards and commendations during her time in service.

Like other Spruance-class destroyers, Ingersoll was designed primarily for anti-submarine warfare (ASW). It was equipped with advanced sonar systems and torpedoes to detect and engage submarines. Later in its career, the ship received upgrades that improved its surface warfare and air defense capabilities.

Ingersoll was decommissioned on 24 July 1998, and stricken from the Naval Vessel Register on 5 November 1999. It was subsequently sunk as a target ship during a training exercise off the coast of California on 14 August 2003.
