U.S. Builders of Large Ships

The shipbuilders listed in this section 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.  In addition, they all have (or had) a significant record of performance, involving more than a few years and 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 commercial ships, rigs and/or oceangoing government ships that are smaller and 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  The second group in this table consists of the 38 companies whose 60 shipyards are no longer active in the shipbuilding market but which, in my judgment, would be included in the first group if they were still around.  Note that the recent downturn in the market means that some of the yards in this table that were active quite recently are now idle: I plan to keep them in the table, however, until it is clear that they are no longer operable.
