The first post-World War I battleship of the French Navy, Dunkerque, was ordered in 1932. Initially two ships were ordered in 1935 in response to Italian orders for the Littorio-class battleships the previous year. These were dual-purpose guns, but were outfitted primarily with time-fused shells for anti-aircraft defense, as the 152 mm guns were expected to fulfill the close-range anti-ship role. The designers eventually settled on the solution that American battleship designers had adopted, using an internal hangar in the hull with a crane to lift aircraft onto a single catapult. France and It… The first, The weight problem was solved by adopting a new type of boiler, designated "Sural" (short for Despite the fact that both vessels remained within the displacement limits, when construction of Their crew numbered 1,569 officers and men, though this changed considerably over the course of their careers, particularly as their anti-aircraft batteries were revised. The The ships' underwater protection system was based on the system used in the By 1937, tensions in Europe had increased significantly as Germany and Italy took increasingly aggressive positions, raising the likelihood of war in the near future. The Richelieus were based on the preceding Dunkerque class, but scaled up to accommodate more powerful 380 mm (15 in) guns and armor to protect them from guns of the same caliber. The 130 mm dual-purpose guns used on the The Project C variants all displaced close to 40,000 long tons (41,000 t) and thus were not seriously considered, as they exceeded the displacement limits by a wide margin.
The belt was The main battery turrets were protected by 430 mm (17 in) of armor plate on the faces, 300 mm (12 in) on the sides, 170 to 195 mm (6.7 to 7.7 in) on the roofs, and 270 mm (11 in) on the rears of the forward turret and 260 mm (10 in) on the superfiring one. The facilities there were not capable of completing the second main battery turret, nor were the Germans interested in allowing the needed armor plates and guns to be shipped there. The Free French forces attempted vainly to land near In October, repair of the hull resumed, but the mattress failed to be effective, and the cofferdam, fitted with a kind of ballast tank, was not put in place before mid-December. They carried a number of small boats, including eight The propulsion system was rated for a total of 155,000 Electrical power was provided by four 1,500 kW (2,000 hp) Their secondary armament was to have consisted of fifteen As designed, the light anti-aircraft battery was to have consisted of 37 mm (1.5 in) automatic guns in twin Mle 1935 mounts, but these were not ready by 1939, and so the two amidships 152 mm turrets were replaced with a group of twelve 100 mm (3.9 in) /45 Mle 1930 anti-aircraft guns in twin turrets. The midship 152 mm (6.0 in) turrets had to be canceled, and twelve 100 mm (3.9 in)/45 Model 1930 guns in six twin 100 mm (3.9 in) mountings, CAD Model 1931, would instead be fitted, as they had been on the last 10,000 tons heavy cruiser, the The defence against aircraft would have been complemented by six or eight 13.2 mm (0.52 in) Hotchkiss quadruple MG mountings (CAQ Model 1929) on the upper platforms of the forward and after towers.This figure of 7 meters (23 ft) width was impressive, compared with the 4.10 meters (13.5 ft) on the The maximum fuel load for peace-time cruising was 5,866 tonnes (5,773 long tons), but in wartime this figure was reduced to 4,700 tonnes (4,600 long tons) to maximize the underwater protection system's effectiveness, since filling the liquid loading compartments to the brim created additional pressure on bulkheads instead of absorbing the pressure of explosion. On 13 June, during the full power speed trials, 32 knots were maintained during three and half hours developing 155,000 shp, and 32.6 knots reached developing 175,000 shp.
The ship was equipped with 380 mm guns, had a high speed, strong armor and very good torpedo protection. 1 turret, one new-built 380 mm gun and three guns, constructed before 1940, intended for After having fired her last 380 mm rounds, during trials after refit, in 1952, the Fire control systems, rangefinders, aviation facilitiesWith the British Eastern Fleet, in the Indian OceanThe world's heaviest turrets will have been: the three 460 mm (18.1 in) gun turrets on the Less than the 181 tonnes (178 long tons) barrel on the The port catapult was on frame 9, and the starboard catapult on frame 24Giorgerini, Giorgio; Nani, Antonio (1973) (in it). Richelieu has pale skin, very long, light blonde wavy hair and swept bangs along with a small lock of hair hanging between her eyes. Since the automatic 37 mm guns were not available, eight Control for the ships' armament relied on five main The ships' belt armor was 327 mm (12.9 in) thick amidships where it covered the machinery spaces and ammunition magazines; it was capped on either end by transverse bulkheads that were 355 mm (14.0 in) thick forward and 233 mm (9.2 in) aft. The radius of possible travel was 9,850 nautical miles (18,240 km; 11,340 mi) at 16 knots (30 km/h; 18 mph), 8,250 nautical miles (15,280 km; 9,490 mi) at 20 knots (37 km/h; 23 mph), and 3,450 nautical miles (6,390 km; 3,970 mi) at 30 knots (56 km/h; 35 mph).During speed trials, in April 1940 developing 123,000 hp 30 knots (56 km/h; 35 mph) were maintained with near 42,000 tonnes (41,000 long tons) displacement, and in June 32 knots (59 km/h; 37 mph) were maintained for 3 hours and 30 minutes, with 43,800 tonnes (43,100 long tons) displacement and 155,000 hp, and 32.68 knots (60.52 km/h; 37.61 mph) were reached with 179,000 hp forcingOne year later, in January 1940, the last 380 mm barrel had been installed, as, in April 1940, the first three 100 mm turrets, and the starboard catapult.
