Escort carriers and similar aviation vessels operated by the Japanese Imperial Army:
Date ranges are commissioning dates, ship counts includes United States Navy and lend-leased Royal Navy vessels (i.e. production totals), count in parentheses is the number of ships in US service. The degree to which hulls were completed before conversion varies from not at all to already launched.
The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slow type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, slower, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
HMS Fencer (D64/R308) was an American-built Attacker-class escort carrier that served with the Royal Navy during the Second World War.
USS Charger (CVE-30) was an escort carrier of the United States Navy during World War II converted from a commercial C3-P&C cargo/passenger liner hull built as Rio de la Plata intended for the Moore-McCormack company's American Republics Line serving the east coast of South America. The ship was requisitioned for conversion to an escort carrier type intended for Royal Navy use and initially commissioned as HMS Charger (D27). Days later the transfer was rescinded with the ship returning to U.S. Navy control to become USS Charger which operated throughout the war as a training ship on the Chesapeake Bay with two ferry missions to Bermuda and Guantánamo Bay, Cuba.
HMS Nabob (D77) was a Ruler-class escort aircraft carrier which served in the Royal Navy during 1943 and 1944. The ship was built in the United States as the Bogue-classUSS Edisto (CVE-41) but did not serve with the United States Navy. In August 1944 the ship was torpedoed by the German submarine U-354 while participating in an attack on the German battleship Tirpitz. Nabob survived the attack, but upon returning to port, was considered too damaged to repair. The escort carrier remained in port for the rest of the war and was returned to the United States following it. Nabob is one of two Royal Navy escort carriers built in the United States which is listed as lost in action during World War II. The ship was sold for scrap by the United States but found a second life when purchased and converted for mercantile use under her British name, Nabob. Later renamed Glory, the ship was sold for scrapping in 1977.
HMS Ruler was a Ruler-class escort carrier of the British Royal Navy during World War II. She was built in the United States as the Bogue-class carrier St. Joseph (AVG/CVE/ACV-50) for Lend-Lease to the United Kingdom.
The Bogue class were a class of 45 escort carriers built in the United States for service with the US Navy and the Royal Navy, through the Lend-Lease program, during World War II. Following the war, ten Bogue-class ships were kept in service by the US Navy and were reclassified for helicopter and aircraft transport operations.
The Avenger-class escort carrier was a class of escort carriers comprising three ships in service with the Royal Navy during the Second World War and one ship of the class in the United States Navy called the Charger Type of 1942-class escort carrier. All three were originally American type C3 merchant ships in the process of being built at the Sun Shipbuilding and Drydock Company Chester, Pennsylvania. The ships laid down in 1939 and 1940 were launched and delivered to the Royal Navy by 1942 under the Lend-Lease agreement.
Type C3-class ships were the third type of cargo ship designed by the United States Maritime Commission (MARCOM) in the late 1930s. As it had done with the Type C1 ships and Type C2 ships, MARCOM circulated preliminary plans for comment. The design presented was not specific to any service or trade route, but was a general purpose ship that could be modified for specific uses. A total of 162 C3 ships were built from 1939 to 1946.
The Taiyō-class escort carrier was a group of three escort carriers used by the Imperial Japanese Navy (IJN) during World War II. Two of the ships were built as cargo liners in the late 1930s and subsequently taken over by the IJN and converted into escort carriers, while the third ship was converted while still under construction. The first ship converted, Taiyō, ferried aircraft and supplies to Japanese possessions before the start of the Pacific War in December 1941 and also served as a training ship between transport missions. Once the war began she did much the same for the newly conquered areas. Her sister ship, Un'yō did much the same in 1942. Chuyō, the last of the three to be converted, only ferried aircraft between Japan and the naval base at Truk before she was sunk by an American submarine in December 1943. Her sisters sometimes had other destinations other than Truk in 1943, but it was also their primary destination until they were damaged by American submarines in late 1943 or early 1944. After finishing their repairs in 1944, the sisters combined convoy escort duties with their transport missions and often ventured as far south as Singapore. Taiyō was the first of the pair to be sunk, torpedoed by an American submarine in August, with Un'yō following her sister a month later.
The Japanese aircraft carrier Taiyō was the lead ship of her class of three escort carriers. She was originally built as Kasuga Maru (春日丸), the last of three Nitta Maru class of passenger-cargo liners built in Japan during the late 1930s for NYK Line. The ship was requisitioned by the Imperial Japanese Navy (IJN) in early 1941 and was converted into an escort carrier. Taiyō was initially used to transport aircraft to distant air bases and for training, but was later used to escort convoys of merchant ships between Japan and Singapore. The ship was torpedoed twice by American submarines with negligible to moderate damage before she was sunk in mid-1944 with heavy loss of life.
Chūyō was a Taiyō-class escort carrier originally built as Nitta Maru, the first of her class of three passenger-cargo liners built in Japan during the late 1930s. She was requisitioned by the Imperial Japanese Navy (IJN) in late 1941 and was converted into an escort carrier in 1942. She spent most of her service ferrying aircraft, cargo and passengers to Truk until she was torpedoed and sunk by an American submarine in late 1943 with heavy loss of life.
Un'yō was a Taiyō-class escort carrier originally built as Yawata Maru (八幡丸), one of three Nitta Maru-class cargo liners built in Japan during the late 1930s. She was transferred to the Imperial Japanese Navy (IJN) during the Pacific War, renamed, and was converted into an escort carrier in 1942. The ship spent most of her service ferrying aircraft, cargo and passengers to various bases in the Pacific. Un'yō was badly damaged by an American submarine in early 1944. After repairs were completed in June, the ship resumed transporting aircraft and cargo. During a return voyage from Singapore in September, she was sunk by the submarine USS Barb.
The Sangamon class were a group of four escort aircraft carriers of the United States Navy that served during World War II.
HMS Nairana was the lead ship of the Royal Navy's Nairana-class escort carriers that saw service in the Second World War. She was built at John Brown & Company shipyards in Clydebank, Scotland. When construction started in 1941 she was intended as a merchant ship, but was completed and launched as an escort carrier, entering service at the end of 1943.
SS Mormacland may refer to one of several Type C3 ships built for the United States Maritime Commission on behalf of Moore-McCormack Lines:
756 Naval Air Squadron was a Naval Air Squadron of the Royal Navy's Fleet Air Arm. It was initially formed as a Telegraphist Air Gunner Training Squadron, operating from March 1941, out of RNAS Worthy Down, in Hampshire, England. TAG training was provided until the No. 2 School was ready in Canada, opening on the 1 January 1943, and 756 NAS disbanded in December 1942. The squadron reformed at RNAS Katukurunda, in Sri Lanka, in October 1943, as a Torpedo, Bomber, Reconnaissance pool. During 1944 and 1945, the squadron undertook a number of detachmemts on different types of Royal Navy aircraft carriers, with it disbanding in December 1945.
767 Naval Air Squadron was a Naval Air Squadron of the Royal Navy's Fleet Air Arm. It was initially formed as a Deck Landing Squadron in 1939, when 811 Naval Air Squadron was renumbered 767 NAS, at RNAS Donibristle. A detachment went to Hyeres de la Palyvestre in the south of France, enabling training in fairer conditions. While here, the squadron took on an operational mission, with a bombing attack on the Italian port of Genoa. With the fall of France the squadron evacuated to Algeria, where it split. Part went to Malta, forming 830 Naval Air Squadron, the other part to HMS Ark Royal, with personnel returning to the UK via Gibraltar. The squadron regrouped at RNAS Arbroath and moved to the Deck Landing School at RNAS East Haven in 1943.
