Large or Otherwise Significant Shipbuilders

U.S. builders of large ships

Since WWI, 80 U.S. shipbuilders have built the larger types of oceangoing vessels, including naval ships and submarines, cargo ships, passenger ships, other special-purpose commercial or governmental ships, and offshore drilling rigs. All have (or had) a significant record of performance, involving more than a few years and more than a few ships. The table below is structured in three groups:
(A) 5 yards - the "big five" - which are actively building most of the U.S. Navy's large commissioned ships and submarines;
(B) 15 yards - the "second tier" - which are actively building commercial ships, rigs and/or oceangoing government ships that are smaller and less expensive than those built by the "big five";
(C) 60 yards which have built significant numbers of large vessels since WWI but which are no longer active.
