French submarine ''Foucault'' (Q70) was a Laubeuf type submarine〔Jane p199〕 of the ''Brumaire'' class, built for the French Navy prior to World War I.〔Conway p209〕 ==Design and construction== ''Foucault'' was ordered by the French Navy as part of its 1906 programme and was laid down at the Cherbourg Naval Yard in November of that year. Work progressed slowly, and she was not launched until 15 June 1912. She was commissioned on 20 June 1914. ''Foucault'' was equipped with licence-built M.A.N. diesel engines for surface propulsion, and electric motors for power while submerged. She carried eight torpedoes, two internally and six externally.〔 ''Foucault'' was named for Léon Foucault, the 19th century French physicist.〔Castel〕 ==Service history== At the outbreak of the First World War ''Foucault'' was part of the French Mediterranean Fleet, and sailed with that force to the Adriatic tasked with bringing the Austro-Hungarian Fleet to battle or blockading it in its home ports. On 15 September 1916, while on patrol off Cattaro under the command of Lt. L Devin, ''Foucault'' was spotted under the surface by two Austro-Hungarian seaplanes. These were L132, flown by Lts. Konjovics and Sewera, and L135 (Lts. Zelezny and.Klimburg). The two planes proceeded to bomb ''Foucault'', scoring hits and forcing her to the surface, Unable to dive and without power, Devin ordered her to be abandoned and scuttled. All her crew escaped without casualties. The seaplanes landed and took the crew prisoner, holding them until the arrival of an Austrian torpedo boat. This incident was the first instance of a submarine at sea being sunk by air attack.〔Price pxiii-xiv〕〔Sieche〕 ==Notes== ==References== * Gardiner R, Gray R: ''Conway’s All the World’s Fighting Ships 1906-1921'' (1985) ISBN 085177 245 5 * Moore, J: ''Jane’s Fighting Ships of World War I'' (1919, reprinted 2003) ISBN 1 85170 378 0 * Price, A: ''Aircraft versus Submarine'' (1973) ISBN 1 84415 091 7 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「French submarine Foucault (Q70)」の詳細全文を読む スポンサード リンク
