S艇
S艇（Schnellboot，英文fast boat之意），是第二次世界大战德国的一种鱼雷艇。盟军则称其E艇，一般被认为E是Enemy（敌人）的意思，但也有可能是指Eilboot（快艇）的意思。 S艇船体比美国的PT艇和英国的机动鱼雷艇（MTB）还要大的多，适合到外海进行长距离作战（约700海浬），使得英国皇家海军开发更新型的鱼雷快艇对应，如Fairmile-D鱼雷艇。

A fast attack craft (FAC) is a small, fast, agile and offensive warship armed with anti-ship missiles, gun and/or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. In size they are usually between 50–800 tonnes and can reach speeds of 25–50 knots.
