A-class torpedo boat

Summary

The A-class torpedo boats were a class of German single-funnelled torpedo boat/light destroyer designed by the Reichsmarineamt for operations off the coast of occupied Flanders in the First World War. The "A" designation was to avoid confusion with older classes and designs. They were classed officially as "coastal torpedo boats" (German: Küstentorpedoboote) to differentiate from larger, ocean-going torpedo boats.

Six groups of vessels were built under the class between 1914 and 1918, increasing in displacement from 109 tons to 335 tons. All had a raised forecastle, shallow draught, and carried one (for most) or two (for A1-A25) 17.7 in (45 cm) torpedo tubes amidships.

These 42 vessels were ordered in three batches - A56 to A67 in 1916, A80 to A91 in 1917, and A96 – A113 in 1918. Designed by A. G. Vulcan, who built all of them except for A83, A84 and A85, which were built by Howaldtswerke at Kiel, while the hulls of A64 to A67 were subcontracted to Seebeckwerft. None of the 1918 batch of 18 vessels were ever completed, and they were all stricken on 3 November 1918, some being up to 35% complete (these were broken up on the stocks) but none being launched.
