Ingalls has built a wide variety of commercial ships and other structures over the years, including- seagoing hopper dredges, oil tankers, tow-boats, offshore cargo vessels and oil supply boats, and roll on/roll off container ships. In the early 1950s the company redirected segments of its shipbuilding capabilities from producing commercial vessels to producing ships for the US Navy's combatant fleet. In 1957, Ingalls received its first submarine construction contract, and the Company produced a total of 12 nuclear-powered attack submarines for the Navy. By the time the shipyard's nuclear facility was decommissioned in 1980, 11 U.S. Navy attack submarines had been overhauled and/or refueled at Ingalls.California-based Litton Industries acquired Ingalls in December 1961. In January 1968 Ingalls Shipbuilding began construction of a new shipyard on a 611-acre tract of land across the Pascagoula River from the Company's existing facilities, developed around the newly-developed modular ship production concept. Since 1975, Ingalls has delivered 76 new major surface warships to the US Navy, including amphibious assault ships, submarine tenders, destroyers, ammunition ships, as well as nuclear submarines. Ingalls has built SPRUANCE (DD 963) Class multimission destroyers, TARAWA (LHA 1) Class general purpose amphibious assault ships, KIDD (DDG 993) Class guided missile destroyers and TICONDEROGA (CG 47) Class Aegis guided missile cruisers.
Ingalls is currently building ARLEIGH BURKE (DDG 51) Class Aegis guided missile destroyers and WASP (LHD 1) Class multipurpose amphibious assault ships.
In June 1998, teaming arrangements under which two competing total ship concepts and designs will be produced for DD 21, the Navy’s 21st Century destroyer, were established. Ingalls and Raytheon Systems Company form one team; with Bath Iron Works partnering with Lockheed Martin Corporation to form the second team.
Ingalls reached all time high employment levels of 25,000 in 1977, and currently employs 10,900. Ingalls maintains Collective Bargaining Agreements with the Pascagoula Metal Trades Council (comprised of unions representing boilermakers, operating engineers, sheetmetal workers, pipefitters, carpenters, painters, laborers, machinists and teamsters), as well as separate unions representing electrical workers (IBEW), office employees and security guards.
