The Motobomba, more properly the Motobomba FFF (Freri Fiore Filpa), was an Italian pattern-running torpedo used by Italian and German air forces during World War II. The designation ''FFF'' was derived from the last names the three men involved with its original design: Lieutenant-Colonel Prospero Freri, Captain-Disegnatore Filpa, and Colonel Amedeo Fiore. The FFF was a diameter electric torpedo which was dropped on a parachute and was designed to steer concentric spirals of between until it found a target. It weighed , and contained a warhead. Its speed was and it had an endurance of 15–30 minutes. It was acknowledged by the Germans as superior to anything they had and US intelligence was eager to get its hands on it after the Armistice with Italy in September 1943. ==Development== The initial development work on the torpedo was carried out at Parioli, near Rome. It was demonstrated in 1935 to Benito Mussolini, Admiral Domenico Cavagnari, General Giuseppe Valle and other high officials. Freri later demonstrated it at the Germania works at Travemünde, the Luftwaffe experimental trials centre, and the Germans were sufficiently impressed to order 2,000 examples. Five-hundred were ordered for the Regia Aeronautica, the first planned uses for them in combat to be against the British naval bases at Gibraltar and Alexandria in 1940. The limiting factor was the fact that only the Savoia-Marchetti SM.82 bomber had the necessary power and range to deliver such a weapon over such a distance. The first version of the FFF were designed to enter the water vertically, but it was found that a tilt device allowing it to make a gentler angled entry was less likely to upset the delicate mechanisms, and this was implemented on the second series. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Motobomba」の詳細全文を読む スポンサード リンク
