Project history

These 'division boats', or flotilla leaders, were basically larger versions of the torpedo boats they were intended to lead, with a similar armament and speed, but of a larger size in order to accommodate the extra staff needed. The most interesting design was the last, D9, which had the beginnings of the 'trawler bow', a raised forecastle which did not extend back as far as the bridge.

Modernizations

1893, both: - 6 x 5 - 37/17; + 3 x 1 - 50/37 SK L/40 C/92

1907, D7; 1910, D8: were reboilered with 2 Marine boilers
