Project history: Coastal torpedo-boat 1914 design, A I type, built by A G Vulcan, Hamburg (hulls of A8, A14, A19 and A24 subcontracted to Sachsenberg Werft (Rosslau) and A4, A10 and A15 to Stettiner Oderwerke). This was the first design for a small coastal torpedo-boat to be used on the Flanders coast. A 2, A 4-A 16, A 19 and A 20 were sent in sections by railway to Antwerp/Hoboken and finished there.
Modernizations: None.
Naval service: Despite being a poor design they saw action in the Channel and suffered heavy losses. A4, A5, A8, A9, A11, A12, A14, A16 and A20 were abandoned in the retreat from Flanders, taken over by Belgium and operated until about 1927 (A20 survived lo be recaptured in 1940 and was not BU until 1948). A2 and A6 were sunk by British destroyers 1.5.1915 in the North Sea. A3 was lost by unknown cause 7.11.1915 en route from Kiel to Danzig. A7 was sunk 21.3.1918 off Flanders coast by French destroyers Capitaine Mehl and Bouclier. A10 was mined 7.2.1918 off Flanders coast. A13 was sunk by British airplanes 16.8.1917 at Ostend, salvaged but 22.11.1917 destroyed by field artillery. A15 was sunk 23.8.1915 by French destroyers Branlebas and Oriflamme off Flanders coast. A17 and A21 were scuttled 13.1.1920 at Kiel by putschists, salvaged next year and BU. A19 was sunk by British destroyers off Flanders coast 21.3.1918.
