The USS Ingersoll (DD-990), a destroyer belonging to the Spruance class, marked the second U.S. Navy vessel to carry the name USS Ingersoll, this time in tribute to Admiral Royal E. Ingersoll (1883–1976), who served as CINC, Atlantic Fleet for a significant part of World War II.

Construction of Ingersoll commenced on 5 December 1977 at Ingalls Shipbuilding in Pascagoula, Miss. It was launched on 10 March 1979 and officially commissioned on 12 April 1980.

Initially stationed in San Diego, CA, Ingersoll later underwent an overhaul in Long Beach, CA, before finally being homeported in Pearl Harbor.

In 1985, Ingersoll became one of the pioneering US Navy vessels to receive the Armored Box Launcher iteration of the Tomahawk cruise missile system. This earlier version accommodated up to four missiles in each of two canisters positioned directly ahead of the pilothouse on the fore deck. However, the system's substantial weight significantly affected the ship's stability, leading to the much more efficient Vertical Launch missile system replacing the obsolete Armored Box Launcher.

On 20 June 1992, while navigating the Straits of Malacca, Ingersoll collided with M/V Matsumi Maru No. 7, a Pakistani oil tanker. Despite minimal flooding, Ingersoll managed to reach the port in Singapore. Temporary repairs were undertaken before the ship returned to Pearl Harbor for comprehensive repairs and overhaul.

Despite being among the newer ships in the Spruance class, Ingersoll was one of the first to be decommissioned. The expenses involved in removing the Armored Box Launcher system and retrofitting the Vertical Launching System likely contributed to the ship's premature decommissioning. Ingersoll was decommissioned and removed from the Navy Directory on 24 July 1998. It was ultimately sunk as a target on 29 July 2003, situated north-northwest of Kauai, Hawaii, at coordinates 023°02′N 160°04′W.
