Project history

The second group of the 1911 fiscal year destroyers was built by Germaniawerft, their boats being more stable than the Blohm & Voss design (the old torpedo-boats S7-57 of the 1885-90 series were in consequence renumbered T7-57, most of them then being used as fast minesweepers).

1920 - 1921, all survived: - 2 x 1 - 88/42, 2 x 1 - 500 TT; + 2 x 1 - 105/42 SK C/06; boilers were replaced by 3 new ones, fuel stowage was 156 t of coal and 80 t of oil. Displacement was 660 / 775 t, maximal speed felt to 31.5 kts, endurance 1800(17)nm.

1928 - 1931, all survived: were reconstructed, displacement was 772 / 884 t, dimensions 75.7 wl 76.1 oa x 7.58 x 3.11 m, maximal speed was 30 kts, boilers were converted to oil firing, fuel stowage was 220 t oil, endurance 1900(17)nm.

1937, all survived: - 1 x 1 - 105/42, 1 x 1 - 500 TT; + 2 x 1 - 20/65 C/30, 1 x 2 - 500 TT
