Ingalls Shipbuilding is a shipyard located in Pascagoula, Mississippi, United States, originally established in 1938, and now part of HII. It is a leading producer of ships for the United States Navy, and, as of 2023, is the largest private employer in Mississippi.^[1]

In 1938, Ingalls Shipbuilding Corporation was founded by Robert Ingersoll Ingalls Sr. (1882–1951) of Birmingham, Alabama, on the east bank of the Pascagoula River in Mississippi.^[2] Ingalls was located where the Pascagoula River runs into the Gulf of Mexico. It started out building commercial ships, including USS George Clymer, which took part in Liberty Fleet Day on 27 September 1941. In the 1950s, Ingalls started bidding on Navy work, winning a contract in 1957 to build 12 nuclear-powered attack submarines.

Litton Industries acquired Ingalls in 1961, and in 1968, expanded its facilities to the other side of the river. Ingalls reached a high point of employment in 1977, with 27,280 workers. In April 2001, Litton was acquired by the Northrop Grumman Corporation.^[3]

On 29 August 2005, Ingalls facilities were damaged by Hurricane Katrina; most of the ships in dock and construction escaped serious harm. While shipbuilding was halted for a while due to the destruction of many buildings, most vehicles and the large overhead cranes are the same that the facility continues to operate today.

On 31 March 2011, Northrop Grumman spun off its shipbuilding sector (including Ingalls Shipbuilding) into a new corporation, Huntington Ingalls Industries.

In 2015, Ingalls Shipbuilding Company signed a contract with US Navy for new destroyers, littoral combat ships, and new landing craft. USS John Finn was one of the first new destroyers and was launched on 28 March. The company is also building the USS Ralph Johnson, USS Paul Ignatius, and USS Delbert D. Black.

On 21 March 2015, the new San Antonio-class amphibious transport dock ship USS John P. Murtha was ceremonially christened. The vessel was launched on 30 October and was commissioned in 2017.

On 27 March 2015, the shipyard received construction contracts for their next destroyers. Ingalls Shipbuilding Company was awarded a $604.3 million contract modification for building USS Frank E. Petersen Jr..

On 31 March 2015, the shipyard also received another contract with a $500 million fixed price to build the eighth National Security Cutter for the US Coast Guard. Most of them will be under construction until 2019. The cutters are the most advanced ships ever built for the Coast Guard.^[4]

On 30 June 2016, Ingalls Shipbuilding signed a contract with US Navy to build the U.S. Navy's next large-deck amphibious-assault warship. The contract included planning, advanced engineering, and procurement of long-lead material, is just over $272 million. If options are exercised, the cumulative value of the contract would be $3.1 billion.^[5]

Ingalls' primary product has been naval ships and naval projects for Egypt, Israel, and Venezuela. In the 1940s, Ingalls attempted to enter the diesel-electric locomotive market. They cataloged an extensive product line, but only one example, known as the model 4-S, was produced. It was sold to the Gulf, Mobile & Ohio Railroad. Ingalls also manufactured covered hopper railroad cars in the early 1980s, producing around 4,000 units, primarily for the lease market via North American Car.^[6]

In Decatur, Alabama, Ingalls Shipbuilding built barges and type B ship barges from 1930 to 1980. In 1980 the shipyard was sold to Trinity Industries that closed in 1981. This site is now called Ingalls Harbor.^[8]
