French submarine Foucault (Q70) was a Laubeuf type submarine [1] of the Brumaire class, built for the French Navy prior to World War I. [2]
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. [2] Foucault was named for Léon Foucault, the 19th century French physicist. [3]
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 Lohner L seaplanes. These were L132, flown by Lts. Konjovics and Sewera, and L135 (Lts. Zelezny and Klimburg). The two planes bombed Foucault, scoring hits which forced her to 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.
