The Chiyoda was a light aircraft carrier of the Imperial Japanese Navy during World War II, originally built as a seaplane tender in 1934, and later converted into a light aircraft carrier. Laid down on December 14, 1936, at Kure Naval Arsenal, she was launched on November 19, 1937, and commissioned on December 15, 1938. The vessel was designed from the outset with versatility in mind, featuring a hull and engine layout based on a high-speed oiler, capable of reaching speeds up to 20 knots, with additional diesel engines allowing her to achieve 28.5 knots. Initially, Chiyoda was equipped with four aircraft catapults and cranes for launching and recovering seaplanes, primarily Kawanishi E7K "Alf" and Nakajima E8N "Dave" floatplanes. Her armament included four 12.7 cm/40 Type 89 naval guns and twelve Type 96 25 mm AA guns. The ship's propulsion system comprised four boilers powering two geared steam turbines generating 56,800 horsepower, with two propellers. During her service, Chiyoda operated extensively in China during the Second Sino-Japanese War and later participated in various operations in the Pacific, including the Aleutians, Solomon Islands, and Mariana Islands. Notably, she was involved in the Battle of Midway as part of the main fleet, carrying submarines intended for Midway operations, but the attack was canceled after Japan's carrier losses. In 1943, Chiyoda was converted from a seaplane tender to a light aircraft carrier, with a wooden flight deck measuring 180 by 23 meters and capable of carrying approximately 30 aircraft. She played a significant role in the Battle of the Philippine Sea in June 1944, where she was bombed, resulting in casualties and aircraft losses. Ultimately, during the Battle of Leyte Gulf in October 1944, Chiyoda was part of the decoy force aimed at diverting Allied attention. She was heavily damaged by U.S. aircraft, cruiser shellfire, and destroyer torpedoes, and was ultimately sunk on October 25, 1944, by gunfire from U.S. cruisers and destroyers. Her loss marked a significant blow to Japan’s naval aviation capabilities, and she was officially removed from the navy list in December 1944.
