Project history

Ordered 12.11.1877. The original bow TT was converted to compressed air in 1880 after it was found that steam obscured the helmsman's view on launching the torpedo. This was replaced during 1887-9 by a spar torpedo and a twin trainable TT mounting aft, but stability was adversely affected and the spar was removed and the superstructure cut down. This vessel was particularly successful and served as a prototype for the '33-metre' type.
