Construction was constantly interrupted by numerous problems, predominantly due to air raids, material supply delays and a shortage of copper.

[2][3] The Type 1936C destroyers were to be armed with six 12.8-centimetre (5.0 in) quick firing guns with 720 rounds of ammunition, with a speed of 20 rounds per minute, which had a range of 19 kilometres (12 mi), to be placed in three LC.41 twin turrets, one forward and two aft.

An advanced radar-controllable fire control system was placed upon the two aft turrets; six 3.7-centimetre (1.5 in) anti-aircraft guns with 12,000 rounds of ammunition, placed in three LM/42 twin mountings, one forward and two aft; eight to 14 2-centimetre (0.8 in) anti-aircraft guns with 16,000–28,000 rounds of ammunition, placed in LM/44 mountings; two quadruple 53.3-centimetre (21.0 in) torpedo tubes (8–12 rounds); and 60 mines with four depth charge launchers.

[2][4] Their propulsion systems were to consist of six Wagner boilers feeding high-pressure superheated steam (at 70 atm (1,029 psi; 7,093 kPa) and 450 °C (842 °F)) to two sets of Wagner geared steam turbines, which were 3.35 metres (11.0 ft) in diameter.

[2] They were to have 70,000 shaft horsepower (52,000 kW) at 390 revs per minute, giving them a top speed of 37.5 knots (69.5 km/h; 43.2 mph).
