Project history: The first pair were ordered 1.4.1878, 58 and 59 on 16.8.1880 and the remainder on 15.2.1881. 56 and 57 were built to a modified design at La Seyne, and had a ram bow; they proved to be a full 2kts slower on trials than the straight-stemmed Thornycroft boats (14.6kts as opposed to 16.2-16.9kts). The French-built boats were fitted with two 'impulse-tubes' which fired the torpedo using an explosive charge whereas the others had the usual torpedo 'frame' dropping gear.
Modernizations: None.
Naval service: They spent most of their careers aboard the TB transport Japon and later aboard the cruiser-like La Foudre until replaced by the specially-built 'alphabetical' TBs. They were stricken or sold between 1897 and 1904, although 56 survived until 1910.
