Which country used small and fast naval ships designated to carry torpedoes into battle during the First World War?
Grillo-class tracked torpedo motorboat The "Grillo"-class was a class of torpedo armed motorboats in service with the "Regia Marina" (the Royal Navy of Italy) during the First World War. The notable feature of these vessels was that each was equipped with a pair of spiked continuous tracks, intended to allow them to climb over harbour booms and attack enemy shipping at anchor. In 1918, two attempts to use them to penetrate Austro-Hungarian harbour defences both ended in failure.
Pre-dreadnought battleship Pre-dreadnought battleships were sea-going battleships built between the mid- to late 1880s and 1905, before the launch of HMS "Dreadnought" . Pre-dreadnoughts replaced the ironclad battleships of the 1870s and 1880s. Built from steel, and protected by hardened steel armour, pre-dreadnought battleships carried a main battery of very heavy guns in barbettes (open or with armoured gunhouses) supported by one or more secondary batteries of lighter weapons. They were powered by coal-fuelled triple-expansion steam engines.
