The Cachalot-class submarines were a pair of medium-sized submarines of the United States Navy built under the tonnage limits of the London Naval Treaty of 1930. They were originally given hull classification symbols V-8 and V-9 and so were known as "V-boats" even though they were unrelated to the other seven submarines (V-1 through V-7) constructed between World War I and World War II. Joseph W. Paige[4] of the Navy's Bureau of Construction and Repair (BuC&R) developed the basic design, but the builder, Electric Boat, was responsible for detailed arrangement; this was fairly bold, since EB had not built any new submarines since finishing four obsolescent boats for Peru.[4]
Although externally much like the later "fleet submarines," internally the Cachalots were quite different. Due to pressure from the Submarine Officers Conference,[4] they featured full double hulls adapted from the Kaiserliche Marine's U-135,[4] direct-drive diesel propulsion systems, a separate crew's mess (reinstated thanks to EB's rearrangement of the internal layout; Portsmouth would follow soon after),[4] and considerable space around the conning tower within the large bridge fairwaterdisambiguation needed (which was drastically cut down in World War II when the three-inch (76 mm) gun was relocated forward of the bridge). EB also relied on electric welding, while Portsmouth clung to riveting;[4] during the war, the riveted boats would leak fuel oil.[6]
The external tanks proved too narrow for easy maintenance,[7] and the MAN diesels were a constant headache, demanding re-engining[7] in 1936.[8] On the other hand, the class made a major contribution to habitability, when Cuttlefish was the first sub fitted with air conditioning,[7] and to effectiveness, being first fitted with the Mark I Torpedo Data Computer (TDC).[9]
Size reduction had gone too far with the Cachalots, limiting their patrol endurance,[4] and they were soon relegated to training.[7]
