What is another word for torpedo-boat?
Pronunciation: [tɔːpˈiːdə͡ʊbˈə͡ʊt] (IPA) 
A torpedo-boat is a small, fast-moving naval vessel designed for launching torpedoes at enemy targets. Synonyms for torpedo-boat include: motor torpedo boat, PT boat, fast attack craft, and torpedo-armed boat. These vessels have played an important role in naval warfare since their invention in the late 19th century. PT boats were famously used by the US Navy in World War II to harass and disrupt enemy shipping. Fast attack craft are a modern variant of torpedo-boats used by many navies today. Despite being small and relatively fragile, these vessels are often very effective at their intended mission of attacking larger, more heavily armed ships.
