Project history

All the boats in the S7-S65 group were adhered to Schichau's standard torpedo boat form, with the maximum breadth of hull well aft, producing a plan that resembled a pear shape.

Modernizations

1893, all: - 1 x 5 - 37/27; + 1 x 1 - 50/37 SK L/40 C/92

1900, S7-14: were reboilered with new locomotive boiler

1908, S15, 16; 1909, S20-22: were reboilered with 1 Marine boiler

1913, T11, 16, 22: were converted to minesweepers; - 1 - 350 TT, 2 x 1 - 350 TT; + mechanical minesweeping gear

Naval service

Some of the earliest boats were discarded 1900-1910, becoming target boats or tenders, or just being broken up, but the majority were rebuilt and reboilered. In 1910 the survivors had their designations changed from S to T, to clear the S numbers for new destroyers. During the war they were used as minesweepers. Pre-war losses were S2, in a collision at the mouth of the Elbe on 13.3.1908; T21, in a collision with her sister T38 on 16.8.1911.
