Project history

The last of the 'thousand tonners', these six ships were authorized in June 1914. They incorporated both AA weapons (two 1pdr) and a new triple 533mm TT, which had been incorporated in the characteristics for Destroyer 1916, ie for the ships to be authorized in 1915, which became the Caldwell class.

DD 66-68 each had a single cruising turbine that could be geared to one shaft. The other ships all had paired cruising turbines.

Modernizations

1917 - 1918, all: - 1 x 1 - 37/43 (on most ships); + 1 DCT (Y-gun)

1930s, all survived: - (1 - 2) x 1 - 37/43; + 2 x 1 - 12.7/90

1942 - 1943, Allen: - 2 x 1 - 12.7/90, 2 x 3 - 533 TT, 1 DCT (Y-gun); + 6 x 1 - 20/70 Mk 4, 6 DCT, presumably SA, SE radars; displacement increased to 1152/1433t.

Naval service

About half of ships of this class served in the European waters in 1917-1918.
