Type 1934A destroyers

The Type 1934A destroyers, also known as the Z5-class, were a group of twelve destroyers built in the mid-1930s for the Kriegsmarine (German Navy). They were slightly modified versions of the preceding Type 1934 class and perpetuated their predecessors' limited endurance and magazine capacity - factors which contributed to the heavy German losses at the Second Battle of Narvik. Five survived the war.

General characteristics
The Type 1934A destroyers had an overall length of 119 m and were 114 m long at the waterline. They had a beam of 11.3 m, and a maximum draft of 4.23 m. They displaced 2171 - 2270 LT at standard load and 3110 - 3190 LT at deep load. The Wagner geared steam turbines were designed to produce 70000 PS which would propel the ship at 36 kn. Steam was provided to the turbines by six Wagner or Benson boilers with superheaters. The Wagner boilers had a pressure of 70 kg/cm2 and a working temperature of 460 °C while the Benson boilers used 110 kg/cm2 at 510 °C. The Type 1934A carried a maximum of 752 t of fuel oil which was intended to give a range of 4400 nmi at 19 kn, but the ships proved top-heavy in service and 30% of the fuel had to be retained as ballast low in the ship. The effective range proved to be only 1825 nmi at 19 kn.

The Type 1934A ships carried five 12.7 cm SK C/34 guns in single mounts, protected by large gun shields, two each superimposed, fore and aft. The fifth gun was carried on top of the rear deckhouse. Their anti-aircraft armament consisted of four 3.7 cm SK C/30 guns in two twin mounts abreast the rear funnel and six 2 cm C/30 guns in single mounts. The ships carried eight above-water 53.3 cm torpedo tubes in two power-operated mounts. Four depth charge throwers were mounted on the sides of the rear deckhouse and they were supplemented by six racks for individual depth charges on the sides of the stern. Enough depth charges were carried for either two or four patterns of 16 charges each. Mine rails were fitted on the rear deck that had a maximum capacity of 60 mines.
