Ryūjō was a light aircraft carrier of the Imperial Japanese Navy. She was laid down by Mitsubishi at Yokohama in 1929, launched in 1931 and commissioned on 9 May 1933. Her final design resulted in a top-heavy unstable vessel and within a year she was back at Kure Naval Yard for modification. With her stability sufficiently improved, Ryūjō was returned to service and employed in operations during the Second Sino-Japanese War. Early on in the Second World War, she participated in subsidiary operations in the Philippines, Java Sea, Bay of Bengal and the Aleutian Islands before being sunk by American carrier aircraft at the Battle of the Eastern Solomons on 24 August 1942. Design: Ryūjō was originally planned as a seaplane tender to replace the aging Wakamiya, but this was later changed to a conventional aircraft carrier of around 9,800-ton standard displacement. Her light displacement was intended to exploit a loophole in the Washington Naval Treaty of 1922. Under the Treaty, Japan's total tonnage of aircraft carriers was limited to 81,000-tons, but aircraft carriers under 10,000-ton standard displacement were not regarded as "aircraft carriers". While Ryūjō was under construction in 1930, the London Naval Treaty finally closed the above mentioned loophole in the Washington Naval Treaty; consequently, Ryūjō was the only light aircraft carrier of her type to be completed by Japan. Hull: Because of the need to keep Ryūjō's weight under 10,000 tons, no armor could be included, though some protective plating was added to the outer hull where the machinery and magazine spaces were located, thereby providing a modest degree of defense against horizontal fire. She was also designed with only a single hangar, which would have left her with an extremely low profile (there being just 4.6 m (15 ft) of freeboard amidships and 3 m (9.8 ft) aft).Between the time the carrier was laid down in 1929 and launched in 1931, however, the Navy doubled her aircraft stowage requirement to 48 in order to give her a more useful air group. This necessitated the addition of a second hangar atop the first, raising freeboard to 15 m (49 ft). Coupled with the vessel's light displacement and narrow beam, the end result produced an unacceptable degree of instability in rough seas, a common flaw amongst many treaty-circumventing Japanese warships of her generation. Even the addition of Sperry active stabilizers failed to compensate for the inherent instability of the new design and in 1934 Ryūjō was taken in hand for extensive modification. Changes included strengthening of the keel, the addition of enlarged bulges to either side of the hull and the removal of two twin 127mm AA gun mountings to reduce her top weight. In 1940 the ship's general seakeeping was improved by raising her forecastle 3.1 m (10 ft) (one deck higher) which reduced the tendency of her bows to dig water in heavier seas. Machinery: Ryūjō's machinery consisted of two sets of geared turbines (similar to those of the Takao-class heavy cruisers) connected to two shafts. Six oil-fired boilers provided steam power. Total horsepower generated was 65,000 shp (48,000 kW) giving the carrier a top speed of 29 knots (54 km/h; 33 mph) during trials. She carried approximately 2900 tons of oil fuel enabling her to cruise 10,000 nautical miles (19,000 km; 12,000 mi) at 14 knots (26 km/h; 16 mph). The boiler uptakes were trunked to the ship's starboard side, approximately amidships, and exhausted horizontally just below flight deck level through two small downward-curving funnels, the ends of which were supported by heavy bracing. This arrangement served to keep the flight deck clear of smoke and fumes. Flight Deck & Hangars: Ryūjō was a flush-deck carrier. In place of an island structure, her navigating and control bridge was located just under the forward lip of the flight deck in a long glassed-in "greenhouse". The hangar box was set back 23 m (75 ft) from the ship's stem, giving Ryūjō a distinctive open bow. Her 156 m (512 ft) flight deck extended well beyond the aft end of the hangars and was supported by twin steel pillars. Six transverse arrester wires were installed on the flight deck and later modernized in 1936 to stop a 6,000 kg (13,000 lb) aircraft. Two elevators serviced the upper and lower hangars and connected them with the flight deck. The forward platform was the largest at 11 m (36 ft) long by 15.7 m (52 ft) wide. The aft platform was much narrower, just 7 m (23 ft) and, by 1940, as larger and more modern carrier aircraft entered service, was only capable of fitting a Nakajima Kate torpedo plane if spotted at an angle with wings folded. This effectively made Ryūjō a single-elevator carrier and considerably hindered her ability to rapidly transfer aircraft in and out of the hangars for rearming and refueling during combat operations. As a result, though she had stowage for 48 aircraft, her normal operating capacity was closer to 37. Armament: As completed, Ryūjō's primary AA armament comprised six twin 127 mm (5.0 in) dual-purpose guns mounted on projecting sponsons, three on either side of the carrier's hull. In 1934, two of these mountings were removed, resulting in a savings of approximately 60 t (60,000 kg) top-weight and improving the ship's overall stability. Two twin 25 mm (0.98 in) AA guns were added at a later date as well as twelve 13.2 mm (0.52 in) Hotchkiss machine-guns. The light machine-guns were replaced in 1942 with six triple-mount 25 mm (0.98 in) AA guns. 127 mm dual-purpose gun 25 mm anti-aircraft guns 13 mm machine guns

Operational history: In August to December 1937, Ryūjō supported land operations of the Japanese Army in China as flagship of Carrier Division 1. Her aircraft complement consisted of 12 Nakajima A4N fighters and 15 Aichi D1A dive bombers. After her less than satisfactory performance there, Ryūjō received extensive reconstruction.In World War II, Ryūjō was commanded by Captain Kato Tadao and was the flagship of Carrier Division 4. The presence of large fleet carriers meant that she was initially assigned to secondary tasks. Her reconstruction proved successful and the performance of her air group, as well as the ship herself in high seas, was satisfactory. In December 1941 Ryūjō supported the invasion of the Philippines, providing air cover for the landings at Davao on 20 December at Jolo on 25 December. Her aircraft complement consisted of 22 Mitsubishi A6M Zero fighters and 16 Aichi D3A "Val" dive bombers. In January 1942 she supported the conquest of Malaya and in February 1942 she attacked American-British-Dutch-Australian forces around Java. On 1 March 1942 she took part in the Battle of the Java Sea, assisting in the sinking of USS Pope (DD-225). In the same month, she operated against the Andaman Islands and along the coast of Burma. In early April, as part of the Indian Ocean raid, Ryūjō attacked shipping in the Bay of Bengal. Together with the cruisers Chōkai, Kumano, Suzuya, Mogami, Mikuma, Yura, and four destroyers, she sank 23 merchant ships. On 6 April she launched air strikes against Cocanada and Vizagapatam in India. In June 1942 Ryūjō was part of the Northern Force that attacked the Aleutian Islands. Ryūjō's planes struck Dutch Harbor on Unalaska Island on 3 June and 4 June 1942. During this operation, one of the Zero fighters from the Ryūjō, flown by Petty Officer Tadahito Koga, crash landed on the island of Akutan. Koga was killed in the crash due to a broken neck, but the aircraft remained largely intact. The aircraft, later dubbed the Akutan Zero, was the first intact Zero fighter to fall into the hands of U.S. military intelligence. Sinking: The sinking of four of Japan's six fleet carriers in the Battle of Midway made Ryūjō much more important to the Japanese Navy. In August 1942 she was reassigned to Carrier Division 2, and with Shōkaku and Zuikaku she was dispatched to the Solomon Islands. Ryūjō's role in the operation was to support a convoy of transports that were to reinforce and resupply Japanese troops on Guadalcanal, and to attack the Allied air base at Henderson Field. This force was commanded by Rear Admiral Chuichi Hara in the cruiser Tone. Meanwhile, the fleet carriers operated against the U.S. Navy's aircraft carriers. This operation resulted in the Battle of the Eastern Solomons.On 24 August 1942, Ryūjō, escorted by the cruiser Tone and the destroyers Amatsukaze and Tokitsukaze, launched a strike against Henderson Field on Guadalcanal from a position 161 km (100.0 mi) north of Tulagi. The first wave, launched at 12:20, consisted of six Nakajima Kate attack planes armed with general-purpose bombs and an escort of six Mitsubishi Zero fighters. A second wave of nine Zero fighters was launched at 1248. By 14:00, Rear Admiral Hara's airmen radioed they had successfully bombed the airfield, losing two fighters and three bombers to enemy fire (one other bomber crash-landed on Ndai Island). Early in the afternoon, the task force was approached by two B-17 bombers, although these aircraft were chased off by anti-aircraft fire and the launch of six Zero fighters. At approximately 15:50, while beginning launching operations, she was attacked by twenty-nine dive bombers and five torpedo bombers from the USS Saratoga (CV-3), and was hit by four bombs (sources differ as to how many) and one torpedo. The torpedo hit flooded the starboard engine room and jammed the ship's rudder, causing Ryūjō to turn in circles and begin listing to starboard. She was soon on fire along her entire length and her engines eventually stopped. As Amatsukaze went alongside to assist in damage control, two B-17 bombers emerged from the clouds and made an unsuccessful attack against Ryūjō. Though her fires had been brought under control, efforts to contain flooding caused by the torpedo hit proved fruitless and the order to abandon ship was given. By 20:00 the carrier capsized and sank along with approximately 120 of her crew and four aircraft (two Kates and two Zeros) still on board in the hangars. Her remaining survivors, including Captain Kato, had been taken off by her escorts. Displacement: Standard: 10,600 t (10,432.6 long tons; 11,684.5 short tons) Loaded: 13,650 t (13,434.4 long tons; 15,046.5 short tons) Length: 179.9 m (590 ft 2.7 in) Beam: 20.8 m (68 ft 2.9 in) Draught: 7.1 m (23 ft 3.5 in) Installed power: 65,000 hp (48,000 kW) Propulsion: 2 shafts, Steam turbines, 6 water-tube boilers Speed: 29 kn (53.7 km/h; 33.4 mph) Range: 10,000 nmi (18,520.0 km; 11,507.8 mi) at 14 kn (25.9 km/h; 16.1 mph) Complement: 924 Armament: 8 × 127 mm (5 in) guns, 4 × 25 mm anti-aircraft guns 24 × 13 mm machine guns Aircraft carried: 48 (operational maximum 37)

The Charles Martel was a pre-dreadnought battleship of the French Navy built in the 1890s. She was laid down in April 1891, launched in August 1893, and completed in June 1897. She was a member of a group of five broadly similar battleships, along with Carnot, Jauréguiberry, Bouvet, and Masséna, which were ordered in response to the British Royal Sovereign class. Like her half-sisters, she was armed with a main battery of two 305 mm (12.0 in) guns and two 274 mm (10.8 in) guns in individual turrets. She had a top speed of 18 kn (33 km/h; 21 mph). Charles Martel spent her active career in the Mediterranean Squadron of the French fleet, first in the active squadron, and later in the Reserve Squadron. She regularly participated in fleet maneuvers, and in the 1901 exercises, the submarine Gustave Zédé hit her with a dummy torpedo, which was widely hailed in the press. Charles Martel was out of service by the outbreak of World War I in 1914, and so she saw no action during the conflict. She was ultimately broken up for scrap in 1922. Design: Charles Martel was the first member of a group of five battleships built to a broadly similar design, but different enough to be considered unique vessels. Design specifications were identical for each of the ships, but different engineers designed each vessel. The ships were based on the previous battleship Brennus, but instead of mounting the main battery all on the centerline, the ships used the lozenge arrangement of the earlier vessel Magenta, which moved two of the main battery guns to single turrets on the wings. The five ships were built in response to the British Royal Sovereign-class battleships. An earlier vessel, also named Charles Martel, was laid down in 1884 and cancelled under the tenure of Admiral Théophile Aube. The vessel, along with a sister ship named Brennus, was a modified version of the Marceau-class ironclad battleships. After Aube's retirement, the plans for the ships were entirely redesigned, though the later pair of ships are sometimes conflated with the earlier, cancelled designs. This may be due to the fact that both of the ships named Brennus were built in the same shipyard, and material assembled for the first vessel was used in the construction of the second.The two pairs of ships were, nevertheless, distinct vessels. General characteristics and machinery: Charles Martel was 115.49 meters (378 ft 11 in) long between perpendiculars, and had a beam of 21.64 m (71 ft 0 in) and a draft of 8.38 m (27 ft 6 in). She had a displacement of 11,639 tonnes (11,455 long tons). Her forecastle gave her a high freeboard forward, but her deck was cut down to the main deck level aft. She was equipped with two heavy military masts. She had a crew of 644 officers and enlisted men. http://photo.starnet..._Martel-97d.jpg Charles Martel had two vertical triple expansion engines each driving a single screw, with steam supplied by twenty-four Lagrafel d'Allest water-tube boilers. Her propulsion system was rated at 14,900 indicated horsepower (11,100 kW), which allowed the ship to steam at a speed of 18 knots (33 km/h; 21 mph). As built, she could carry 650 t (640 long tons; 720 short tons) of coal, though additional space allowed for up to 980 t (960 long tons; 1,080 short tons) in total. Armament and armor: Charles Martel's main armament consisted of two Canon de 305 mm Modèle 1887 guns in two single-gun turrets, one each fore and aft. She also mounted two Canon de 274 mm Modèle 1887 guns in two single-gun turrets, one amidships on each side, sponsoned out over the tumblehome of the ship's sides. Her secondary armament consisted of eight Canon de 138.6 mm Modèle 1888 guns, which were mounted in single turrets at the corners of the superstructure. She also carried four 9-pounder quick-firing guns, twelve 3-pounders, and eight 1-pounder revolving cannons. Her armament suite was rounded out by two 450 mm (18 in) torpedo tubes, which were submerged in the ship's hull. The ship's armor was constructed with nickel steel. The main belt was 460 mm (18 in) thick amidships, and tapered down to 250 mm (9.8 in) at the lower edge. On either end of the central citadel, the belt was reduced to 305 mm (12.0 in) at the waterline and 250 mm on the lower edge; the belt extended for the entire length of the hull. Above the belt was 101 mm (4.0 in) thick side armor. The main battery guns were protected with 380 mm (15 in) of armor, and the secondary turrets had 101 mm thick sides. The main armored deck was 69 mm (2.7 in) thick. The conning tower had 230 mm (9.1 in) thick sides. Career: Charles Martel was laid down in January April 1891 and launched in August 1893. After completing fitting-out work, she was commissioned into the French Navy in June 1897. She was delayed in completing her sea trials, as her boiler tubes had to be replaced with a safer, weld-less design, following an accident aboard Jauréguiberry with her welded tubes. Following her commissioning for service, she was assigned to the Mediterranean Squadron. In 1900, she became the flagship of Rear Admiral Roustan, the commander of the Second Division of the Mediterranean Squadron.The Mediterranean Squadron, including Charles Martel, conducted an extensive cruise with the Northern Squadron in June–July 1900, which culminated in a Grand Review of the fleet in Cherbourg at the end of July.During the 1901 maneuvers, Charles Martel was hit by a training torpedo fired by the submarine Gustave Zédé, which created an uproar in the press. By 1903, Charles Martel was transferred to the Reserve Squadron, along with three other battleships and three armored cruisers. The ship did not participate in the annual fleet maneuvers in July–August of that year. She remained in the Reserve Squadron, which was renamed the Second Squadron in 1906; by that time, she was in the Second Division of the Squadron, under the command of Rear Admiral Germinet.The ship was maintained in a state of en disponibilité armeé, a state of reduced readiness with a minimal crew. Charles Martel was in full commission for three months of the year, and in reserve with a reduced crew for the remainder. She remained in this status for the duration of 1907. By the outbreak of World War I in August 1914, Charles Martel had been laid up in the port of Brest, along with Carnot. Both ships were retained on the effective list, however, pending the completion of the new Normandie-class battleships.Charles Martel was ultimately stricken from the naval register in 1922 and sold for scrapping that year.
