National Steel and Shipbuilding Company

[3] NASSCO performs ship repairs and conversions for the United States Navy in all four shipyard locations: San Diego, Norfolk, Bremerton, and Mayport.

The origin of NASSCO traces to 1905 and a small machine shop and foundry known as California Iron Works.

National Iron Works came with a shipyard, which expanded significantly during World War II.

[8] National Iron Works built some important San Diego structures, such as some of the plants in which Convair manufactured aircraft for World War II.

[9][10][11] However, in 1959 Smith sold National Steel and Shipbuilding to four other corporations, including Kaiser Industries and Morrison-Knudsen.

[18] On October 31, 2011, General Dynamics-NASSCO acquired Metro Machine Corp, a surface-ship repair company in Norfolk, Virginia, and renamed it NASSCO-Norfolk.

[21] In December 2012 the company signed a contract to build two 764-foot (233 m) container ships powered by liquefied natural gas (LNG).

In 2001 the Navy awarded NASSCO its largest order in company history, to build the Lewis and Clark-class dry cargo ships (T-AKE), a 14-ship program with a contract value of $3.7 billion.
