Japanese aircraft carrier Soryu

Japanese aircraft carrier Soryu was a fast fleet carrier built for the Imperial Japanese Navy during the 1930s. As the lead ship of her class, she was a pioneering design that emphasized speed and air power over armor protection. *Sōryū* played a prominent role in the opening months of the Pacific War, participating in the attack on Pearl Harbor and operations across the Pacific Ocean. She was ultimately sunk by United States Navy dive bombers during the pivotal Battle of Midway in June 1942.

Design and construction

The design of *Sōryū* was heavily influenced by the earlier carrier *Ryūjō* and the provisions of the Washington Naval Treaty. Naval architects at the Kure Naval Arsenal, led by Vice Admiral Fukuda Keiji, sought to create a fast carrier capable of operating a large air group, resulting in a long, narrow hull powered by advanced Kanpon boilers and geared turbines. Her construction, beginning in late 1934, incorporated lessons from the Great Kantō earthquake and prioritized a large, open hangar space served by three aircraft elevators. Although lightly armored to save weight for her impressive 34.5-knot speed, she featured a modern anti-aircraft suite of 127 mm dual-purpose guns and later, numerous 25 mm autocannons. She was launched in December 1935 and commissioned into the Combined Fleet in late 1937, immediately becoming a key asset.

Operational history

Upon commissioning, *Sōryū* was assigned to the Second Carrier Division and saw early service in the Second Sino-Japanese War, conducting air operations off the coast of China. At the start of the Pacific War, as part of the Kido Butai (First Air Fleet) under Vice Admiral Chūichi Nagumo, she launched aircraft for the attack on Pearl Harbor in December 1941. She subsequently supported the invasion of Wake Island and the Indian Ocean raid, where her aircraft helped sink the British carrier HMS *Hermes* near Ceylon. In early 1942, she participated in raids on Darwin and operations in the Dutch East Indies, establishing dominance across the Southwest Pacific. Her final operation was the planned invasion of Midway Atoll.

Aircraft complement

*Sōryū*'s air group typically consisted of 63 operational aircraft with space for several reserves. At the start of the war, this complement was organized into three squadrons (*kōkūtai*): 18 Mitsubishi A6M Zero fighters for air superiority and escort, 18 Aichi D3A "Val" dive bombers for anti-ship strikes, and 27 Nakajima B5N "Kate" torpedo bombers capable of level bombing. These aircraft were renowned for their range and effectiveness, as demonstrated at Pearl Harbor and against HMS *Prince of Wales*. The air group was commanded by experienced officers like Lieutenant Commander Takashige Egusa, a famed dive-bomber leader. Pilots and crew were among the most trained in the Imperial Japanese Navy Air Service.

Fate

During the Battle of Midway on 4 June 1942, *Sōryū* was part of the Kido Butai's main carrier force. While her aircraft were being re-armed for a second strike, the ship was caught vulnerable on her flight deck. She was attacked by SBD Dauntless dive bombers from the American carrier USS *Enterprise*, led by Lieutenant Commander Wade McClusky. Three or four bombs struck her, igniting catastrophic fires among armed and fueled aircraft in the hangars. The resulting explosions crippled the ship within minutes. After the order to abandon ship was given, she was scuttled by torpedoes from the destroyer *Isokaze*. *Sōryū* sank with the loss of 711 officers and crew, including her captain, Ryusaku Yanagimoto. Her sinking, along with that of *Kaga* and *Akagi*, marked a decisive turning point in the Pacific War.
