German torpedo boat T34

The German torpedo boat T34 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine (German Navy) during World War II. Completed in mid-1944, the boat was still working up in the Baltic when she struck a mine in November and sank.

Design and description

The Type 39 torpedo boat was conceived as a general-purpose design, much larger than preceding German torpedo boats.[1] The boats had an overall length of 102.5 meters (336 ft 3 in) and were 97 meters (318 ft 3 in) long at the waterline. They had a beam of 10 meters (32 ft 10 in), a draft of 3.22 meters (10 ft 7 in) at deep load and displaced 1,294 metric tons (1,274 long tons) at standard load and 1,754 metric tons (1,726 long tons) at deep load.[2] Their crew numbered 206 officers and sailors.[3] The Type 39s were fitted with a pair of geared steam turbine sets, each driving one propeller, using steam from four high-pressure water-tube boilers. The turbines were designed to produce 32,000 shaft horsepower (24,000 kW) which was intended give the ships a maximum speed of 33.5 knots (62.0 km/h; 38.6 mph). They carried enough fuel oil to give them a range of 2,400 nautical miles (4,400 km; 2,800 mi) at 19 knots (35 km/h; 22 mph).[4]

As built, the Type 39 ships mounted four 10.5 cm (4.1 in) SK C/32 guns in single mounts protected by gun shields; one forward of the superstructure, one between the funnels, and two aft, one superfiring over the other. Anti-aircraft defense was provided by four 3.7 cm (1.5 in) SK C/30 AA guns in two twin-gun mounts on platforms abaft the rear funnel and a dozen 2 cm (0.8 in) C/38 guns. One quadruple mount was positioned on the aft superstructure and two more were fitted on the bridge wings. They carried six above-water 533 mm (21 in) torpedo tubes in two triple mounts amidships and could also carry 30 mines; the full complement of 60 mines made the ships top-heavy which could be dangerous in bad weather. For anti-submarine work the boats were fitted with a S-Gerät sonar and four depth charge launchers. The Type 39s were equipped with a FuMO 21 radar[Note 1] and various FumB[Note 2] radar detectors were installed late in the war.[5]

Construction and career

T34 was ordered on 20 January 1941 from Schichau, laid down at their Elbing, East Prussia, shipyard on 5 March 1943 as yard number 1516, launched on 23 October 1943 and commissioned on 12 August 1944. Kapitänleutnant Freiherr von Lüttitz was appointed in command. As part of her lengthy working up, she conducted gunnery practice with the radio-controlled target ship Hessen in the Baltic on 20 November, the boat struck a mine and sank off Cape Arkona at 54°40′N 13°29′E with the loss of 62 crewmen.[6]
