7 Military Shipbuilding Companies: Empowering Modern Warfare

The U.S. military heavily relies on advanced naval vessels and submarines to protect the seas and the nation. Military shipbuilders design, build, and deliver state-of-the-art technology that can effectively operate in the most challenging environments and fulfill various missions. See how these companies are shaping the future of U.S. naval dominance and submarine superiority.

What Are Shipbuilding Military Contractors?

Shipbuilding military contractors are specialized companies that focus on designing, constructing, modernizing, and maintaining military vessels for naval forces. These contractors collaborate with the government and military organizations, particularly the U.S. Navy, to manufacture a variety of ships, including nuclear submarines, aircraft carriers, amphibious ships, and surface combatants. In this process, the SUPSHIPs (Supervisors of Shipbuilding) evaluate the construction and business practices of Navy shipbuilders operating in the private sector.
