R-class
Design and Construction Notes
The 27 R-class submarines were built to two distinctly different designs at three shipyards. Both designs had similar operational and military characteristics, but had vastly different internal arrangements, equipment installations, and external appearances. The two designs were developed by the Electric Boat Company (EB) of New York City (later Groton, CT.) and the Lake Torpedo Boat Company of Bridgeport, CT. R-1 through R-14 were of the EB design and were built at Bethlehem Quincy near Boston (formerly Fore River Shipbuilding Company). R-15 through R-20 were of the EB design and built at Bethlehem San Francisco (formerly Union Iron Works). R-21 through R-27 were built by Lake at his Bridgeport yard.
