Large Shipbuilders


The shipbuilders listed in this section of ShipbuildingHistory.com operate (or used to operate) mid-sized to large shipyards building oceangoing vessels, including naval ships and submarines, cargo ships, passenger ships, other special-purpose commercial or governmental ships, and offshore drilling rigs and structures.  In addition, they all have (or had) a significant record of performance, i.e., they were in business for more than a few years and built more than a few ships.  The first of the two groups in this table includes the two companies whose five shipyards collectively build all the Navy's big ships and submarines, plus the eight "second tier" companies whose 15 shipyards build ships that are somewhat smaller and a lot less expensive than those built by the "big two".  The second group in this table consists of the 38 companies whose 60 shipyards are no longer active in the shipbuilding market but which, in my judgment, would be included in the first group if they were still around.
