History: Surcouf was a French submarine ordered to be built in December 1927, launched on 18 October 1929, and commissioned in May 1934. Surcouf – named after the French privateer Robert Surcouf – was the largest submarine ever built until surpassed by the first Japanese I-400-class submarine in 1943. Her short wartime career was marked with controversy and conspiracy theories. She was classified as an "undersea cruiser" by sources of her time.

The Washington Naval Treaty had placed strict limits on naval construction by the major naval powers, but submarines had been omitted. The French Navy attempted to take advantage of this by building three "corsair submarines", of which Surcouf was the only one to have been completed.

Surcouf was designed as an "underwater cruiser", intended to seek and engage in surface combat. For reconnaissance, she carried a Besson MB.411 observation floatplane in a hangar built abaft of the conning tower; for combat, she was armed with six 550 mm (22 in) and four 400 mm (16 in) torpedo tubes and twin 203 mm (8 in) guns in a pressure-tight turret forward of the conning tower. The guns were fed from a magazine holding 60 rounds and controlled by a director with a 5 m (16 ft) rangefinder, mounted high enough to view a 11 km (5.9 nmi; 6.8 mi) horizon, and able to fire within three minutes after surfacing. Using her periscopes to direct the fire of her main guns, Surcouf could increase this range to 16 km (8.6 nmi; 9.9 mi); originally an elevating platform was supposed to lift lookouts 15 m (49 ft) high, but this design was abandoned quickly due to the effect of roll. In theory, the Besson observation plane could be used to direct fire out to the guns 24 mi (21 nmi; 39 km) maximum range. Anti-aircraft cannon and machine guns were mounted on the top of the hangar.

Although she had her impressive specification, Surcouf proved to be plagued by mechanical problems: her trim was difficult to adjust during a dive, on the surface she rolled badly in rough seas, and she took over two minutes to dive to a depth of 12 m (39 ft), making her vulnerable to aircraft.
Type: Submarine
Primary Country:
France is one of Europe’s largest countries. It is bordered by six countries other nations: Germany, Belgium and Luxembourg to the northeast, Switzerland and Italy to the southeast and Spain to the southwest. The United Kingdom borders France via the English Channel. The country is considered to be the gateway to Europe as there are several large international airports (two of these can be found in Paris), ferry terminals and the French rail service.

In 486, Frankish tribes unified under Merovingian kingship. In 843, Western Francia was established from the division of the Carolingian Empire. In 1789, the French monarchy was overthrown, and in 1792, the First French Republic was founded. In 1958, the Fifth French Republic was established.
