95-516: A first step towards re-armament, intended to provide Germany with experience in submarine construction and operation and lay the foundation for larger boats to build upon. Only one of these submarines survive; the prototype CV-707 , renamed Vesikko by the Finnish Navy which later bought it. On 3 February 2008, The Telegraph reported that U-20 had been discovered by Selçuk Kolay (a Turkish marine engineer ) in 80 feet (24 m) of water off

152-789: The British in number of submarines. This agreement was signed on 18 June 1935, and U-1 was commissioned 11 days later. The defining characteristic of the Type II was the small size, its surfaced displacement being between half and one third that of the Type VII , and one third to one fourth of the Type IX 's (depending on the variants used for comparison). Known as the Einbaum ("dugout canoe"), it had some advantages over larger boats, chiefly its ability to work in shallow water, dive quickly, and increased stealth due to

Six were stripped down to their hulls, transported by river and truck to Linz (on the Danube), and reassembled for use in the Black Sea against the Soviet Union . In contrast to other German submarine types, few Type IIs were lost. This reflects their use as training boats, although accidents accounted for several vessels. These boats were

323-435: The sides of the external hull. These saddle tanks were used to accommodate additional diesel storage tanks. The diesel oil would float atop the saddle tanks. As oil was consumed, water would gradually fill the tanks to compensate for the positive buoyancy. The range was nearly doubled to 3,450 nmi (6,390 km; 3,970 mi) at 12 knots (22 km/h; 14 mph) and enabled the Type II to conduct longer operations around
