USS Cachalot (SS-170)
USS ''Cachalot'' (SC-4/SS-170), the lead ship of her class and one of the "V-boats", was the only ship of the United States Navy to be named for the sperm whale. Her keel was laid down by the Portsmouth Navy Yard. She was launched on 19 October 1933 as ''V-8'' (SC-4) sponsored by Miss K. D. Kempff, and commissioned on 1 December 1933 with Lieutenant Commander Merril Comstock〔He would later replace Stuart S. Murray as Admiral Lockwood's Chief of Staff. Blair, Clay, Jr. ''Silent Victory'' (Philadelphia: Lippincott, 1975), p.549.〕 in command. ''Cachalot'' was the first submarine to have the Torpedo Data Computer, Arma Corporation's Mark 1,〔Blair, p.986.〕 installed.
==Design==
''Cachalot'' was built by the Portsmouth Navy Yard, as were most of the previous V-boats. She differed from her sister ''Cuttlefish'' (the first submarine built entirely by Electric Boat) mainly in retaining the riveted (vice welded) construction of most previous submarines. Both were medium-sized submarines built under the tonnage limits of the London Naval Treaty of 1930. An extensive study was conducted to determine the optimum submarine size under the treaty restrictions, factoring in total force, endurance, and percentage of the force that could be maintained on station far from a base, as in a Pacific war scenario.〔Friedman, pp. 189-193〕 Despite the calculation process, size reduction had gone too far with the ''Cachalot''s, limiting their patrol endurance.〔 After three Pacific war patrols, ''Cachalot'' was relegated to training duties in September 1942, once numerous ''Gato''-class boats became available.〔Alden, p.39.〕
The as-built engine specifications were two BuEng-built, MAN-designed M9Vu 40/46 nine-cylinder〔Alden, p.211.〕 two-cycle direct drive main diesel engines, each,〔〔 with one BuEng MAN〔Alden, p.210.〕 two-cycle auxiliary diesel engine,〔 driving a electrical generator.〔 The auxiliary engine was for charging batteries or for increased surface speed via a diesel-electric system providing power to the main electric motors. As with most V-boats, the main engines proved troublesome, and were replaced in 1937-38 by two Winton GM 16-278 16-cylinder four-cycle diesels, each.〔
