Type VIID
The type VIID boats, designed in 1939 and 1940, were a lengthened - by 10 m (32 ft 10 in) - version of the VIIC for use as a minelayer. The mines were carried in, and released from, three banks of five vertical tubes just aft of the conning tower. The extended hull also improved fuel and food storage.
On the surface the boat used two supercharged Germaniawerft, 6 cylinder, 4-stroke F46 diesels delivering 3,200 bhp (2,400 kW) at between 470 to 490 rpm. When submerged the boat used two AEG GU 460/8-276 electric motors giving a total of 750 shp (560 kW) at 285 rpm.
Only one (U-218) managed to survive the war; the other five were sunk, killing all crew members.

Famous quotes containing the word type:
“The ideal American type is perfectly expressed by the Protestant, individualist, anti-conformist, and this is the type that is in the process of disappearing. In reality there are few left.”
