All 25 were ordered in 1914, and were designed and built by A.G. 'Vulcan', at their Hamburg yard.
All 30 were ordered in two batches - 24 vessels in 1915, and 6 added later. All were designed and built by F. Schichau Werke, at their Elbing yard. The second batch were 2 tonnes heavier, and had a breadth of 5.82 metres (18ft 5.25in).
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.
These twelve vessels were ordered in 1916, and were designed and built by F. Schichau at Elbing.
These last four vessels were designed and built by F. Schichau Werke, at their Elbing yard, with a slight variation in their dimensions from the 1916 design. The first two served in a minesweeper flotilla and the last two in an escort flotilla prior to the surrender.
