German Type XXI U Boat "U-2511"
Legend has it that Type XXI boats were designed from a sketch by Admiral Doenitz himself, whatever the truth he approved their design in June 1943 and an initial order was placed for 200 boats. The were a double hulled boat of ocean-going type with high submerged speeds. Her high speed was achieved by plating over the pressure hulls with a thin streamlined casing. The two hulls sat over each other with plating connecting them, the upper hull contained the living quarters, engines etc, the much smaller lower hull contained batteries, provisions etc.
The boats were required to be built quickly so a very high degree of sub assembly of pre-fabricated parts and sections was designed into their construction, in fact the four main units would arrive at the slip to be completed very quickly. The conning tower was of an enclosed streamlined design to cut down underwater drag. This was also popular with watch keepers during cold winter nights in the North Atlantic.
The original order placed in late 1943 was for 200 units, this was later increased to over 1,200 units however only 118 boats were eventually built.
Range on the surface was 15,500 miles at 10 knots, she could maintain a submerged sprint speed of 17.5 knots for 1 hr. However running at 5 knots submerged she could stay down for 3 days or at 10 knots 11 hrs. Then using a snorkel she could clean air and recharge batteries in only a few hours. Great thought was given to accommodation and crew comfort, this was necessary as they were designed for a cruise lasting 150 days, mostly submerged. These boats were the first of a class that if introduced earlier could quite likely have changed the outcome of WWII.
