U-boat Type VII C U-boat.

V-Ray materials, polygonal quads and tris.

The Type VIIC was the workhorse of the German U-boat force, with 568 commissioned from 1940 to 1945.[76] The first VIIC boat commissioned was the U-69 in 1940. The Type VIIC was an effective fighting machine and was seen almost everywhere U-boats operated, although its range of only 8,500 nautical miles was not as great as that of the larger Type IX (11,000 nautical miles), severely limiting the time it could spend in the far reaches of the western and southern Atlantic without refueling from a tender or U-boat tanker.[76] The VIIC came into service toward the end of the "First Happy Time"[Note 6] near the beginning of the war and was still the most numerous type in service when Allied anti-submarine efforts finally defeated the U-boat campaign in late 1943 and 1944.[76]
For submerged propulsion, several different electric motors were used. Early models used the VIIB configuration of two AEG GU 460/8-276 electric motors, totaling 750 PS (550 kiloWatt; 740 shp) with a max rpm of 296, while newer boats used two BBC GG UB 720/8, Garbe, Lahmeyer & Co. RP 137/c or Siemens-Schuckert-Werke (SSW) GU 343/38-8 electric motors with the same power output as the AEG motors.[76]
Perhaps the most famous VIIC boat was U-96, featured in thClass overview
