Shipbuilding in the USA
The US shipbuilding industry includes 8 major shipbuilding companies that manufacture six main product lines: submarines, surface warships, large amphibious ships, aircraft carriers, auxiliary and research vessels.
These shipbuilding companies are not equivalent and are divided into two levels:
Level 1 - The Big Six: Newport News Shipbuilding, Avondale, Ingalls owned by Huntington Ingalls Industries (HHI, a subsidiary of Northrop Grumman) and General Dynamics Electric Boat Division, Bath Iron Works, NASSCO, which are owned by General Dynamics Corporation.
Level 2 - Austal USA (a subsidiary of the Australian shipbuilding company Austal) and Marinette Marine Corporation (was bought by the Italian Fincantieri)
US shipbuilding is almost entirely focused on military products. Moreover, shipbuilding is based on monopsony - i.e. monopoly of one buyer, namely the US Navy (Navy). The share of civil shipbuilding is minimal, only 1% of world shipbuilding (of the Big Six, only NASSCO has recently been successfully operating in the civil shipbuilding market).
