Carrier aircraft used during World War II
From Wikipedia, the free encyclopedia
Over 700 different aircraft models were used during World War II.[1][better source needed] At least 135 of these models were developed for naval use,[2][better source needed] including about 50 fighters[3][better source needed] and 38 bombers.[4][better source needed]
Only about 25 carrier-launched aircraft models were used extensively for combat operations. Of these, nine were introduced during the war years after the Japanese attack on Pearl Harbor brought United States into the war, four by the United States Navy (USN) and three by the Royal Navy (RN) and two by the Imperial Japanese Navy (IJN).
The table below lists the principal carrier-launched fighters and bombers used during World War II. They are listed within each aircraft type in chronological order of their introduction to service. Allied reporting names such as "Val" and "Kate" are included for IJN aircraft. Neither Germany nor Italy put carriers or carrier-launched aircraft into service. Some Axis fighters are included in the table below for comparison with the Allied fighters that met them in combat.

Notes:
- Values were obtained from multiple sources. Some reported values may not be directly comparable to others in the same column.
- Combat ranges for some of the aircraft could be extended using drop tanks containing supplemental fuel.
- Japanese carrier aircraft designations for planes introduced after 1922 typically adhered to the following conventions. The first letter indicated the aircraft type, "A" for fighter, "B" for torpedo bomber, "C" for reconnaissance, and "D" for dive bomber. The last letter indicated the manufacturer, "A" for Aichi, "M" for Mitsubishi, "N" for Nakajima, and "Y" for Yokosuka. The "Type" indicated the last two digits for the Japanese year that the plane was adopted for service. For example, the "D3A (Type 99)" was a dive bomber manufactured by Aichi and adapted for service during the Japanese Year 2599 (1939). The plane was actually introduced for combat in 1940. The Allies referred to it as a "Val".
Relative aircraft capabilities were not the only factors that contributed to success or failure for carrier aircraft in combat. Attack coordination and tactics, along with pilot skill, determination, and willingness to self-sacrifice were at least as important and perhaps more so. For example, both the new, high-performing Grumman TBF Avenger and the obsolete Douglas TBD Devastator were slaughtered as they tried to deliver their torpedoes at Midway without fighter protection. But their pilots' dogged pressing of their attacks in the face of almost hopeless odds created opportunities for the dive bomber pilots that, by luck as well as by determination, arrived in a timely manner to sink four IJN carriers. The effectiveness of the special attacks ("kamikaze") late in the war using mostly outdated aircraft can also be attributed to pilot determination and self-sacrifice. Nonetheless, other things being equal, faster, more maneuverable aircraft with longer ranges and better armament contributed to successful combat outcomes.
Carrier aircraft types, functions, and features
Carrier aircraft types.
The types of aircraft usually launched from aircraft carriers were fighters, torpedo bombers, and dive-bombers. Floatplanes were also launched from some carriers but were typically catapulted from cruisers and battleships. Land-based aircraft types were frequently launched from carriers when delivering them to forward bases, such as when Curtiss P-40 Warhawk fighters flew from carriers to newly captured land-bases during the Allied invasion of North Africa. Sometimes land-based aircraft were launched from carriers for special operations, such as the USN Doolittle Raid, when B-25s were launched for a raid on Tokyo. Some carrier aircraft served in dual roles, such as fighter-bomber and bomber-reconnaissance aircraft.
Carrier aircraft functions.
- Torpedo and dive bombers attacked enemy warships, transports, merchant ships, and land installations.
- Fighters accompanied bombers on attack missions, protecting them during interceptions by enemy fighters. Fighters maintained overhead in Combat Air Patrols (CAP) protected their carriers and other warships in the fleet by intercepting enemy bombers and by attacking submarines.
- Fighters and bombers were also widely used for reconnaissance and sometimes used for mine laying or for spotting to assist bombardment by warships.
Carrier aircraft features.
- Size of aircrew. With few exceptions, fighters had a single crewmember, the pilot, while dive-bombers had two and torpedo bombers had three crewmembers. The RN valued a second crewmember in fighters for observation and navigation, and the Fairey Fulmar and the Fairey Firefly. The Blackburn Roc was a "turret fighter" and the second crewmember operated the turret
- Armament. Fighters and bombers typically had two to four machine guns, sometimes six. These were mostly 7.7mm or 7.62mm (.303in), but the heavier 12.7mm (.50in) were on some RN and USN aircraft. The IJN Zero fighter had the more destructive 20mm (.79in) cannon[5] in addition to machine guns. Later in the war, RN and USN fighters also had 20mm cannon in addition to or instead of machine guns. After 1943, some fighters and bombers were also capable of firing 12.7 cm (127mm) (5 in) rockets. Bombers also carried bombs or a torpedo, the maximum possible weight for which generally increased with new introductions during the war. Most fighters could carry a small bomb load.
- Self-sealing fuel tank. Self-sealing fuel tanks retarded or eliminated the flow of fuel from a tank that has been holed during combat. This was typically accomplished by incorporating a material that swelled when it came into contact with fuel. Many RN and USN carrier aircraft used this technology, but it involved adding weight, and the IJN was reluctant to sacrifice range and maneuverability for improved survivability.
- Protective armor. Like self-sealing fuel tanks, protective armor for the aircrew improved survivability at the cost of performance. The RN and USN armored their carrier aircraft, protecting the aircrew, but the IJN typically did not.[6]
- Number of wings. Carrier aircraft introduced after 1937 were all monoplanes except for the biplane RN Fairey Albacore which was an improved version of the Swordfish. The biplane Fairey Swordfish, introduced in 1936, was removed from front line combat but put onto anti-submarine convoy escort served through the entire war.
- Folding wings. Monoplane carrier aircraft introduced after 1936 almost all had folding wings to reduce the space taken up in hangars. . Exceptions included the Mitsubishi A5M "Claude" fighter and the Douglas SBD Dauntless and Yokosuka D4Y "Judy" dive bombers.
- Cockpit. Some early aircraft had open cockpits, but newer introductions typically had enclosed cockpits.
- Undercarriage. Most of the carrier aircraft introduced after 1937 had retractable landing gear to reduce drag. The two exceptions, introduced in 1940, were the RN Fairy Albacore torpedo bomber and the IJN Aichi D3A2 "Val" dive bomber.
Pre- and early-war aircraft (1936-1941)
Chinese land-based aircraft vs. Japanese carrier aircraft
During the short “Shanghai Incident” in 1932, Japanese carrier-launched fighters and bombers and water-launched floatplanes attacked areas in and around the city. In one engagement, a group of three Mitsubishi B1M torpedo bombers and three Nakajima A1N fighters were attacked by a lone Boeing 218 fighter flown by Robert McCawley Short, an American pilot training Chinese flyers. He was shot down and the following month, Japanese fighters were unsuccessfully opposed by Chinese Curtiss Hawk fighters, some of which were also shot down.[7]
Over the next five years, IJN introduced improved fighters including the Nakajima A2N in 1932, the first purely Japanese-designed fighter. In 1936, the Nakajima A4N entered service. The year after that, the Mitsubishi A5M "Claude" became the world's first low-wing, carrier-launched monoplane. It was highly maneuverable and the direct predecessor of the famed Mitsubishi A6M Zero introduced three years later.
At the time the Second Sino-Japanese War began in July 1937, IJN had about 200 fighters and bombers and 62 floatplanes available to attack. The Imperial Japanese Army (IJA0 had force concentrations in China's north and agreed that IJN would be responsible for aerial operations over central China. Three aircraft carriers with a total of 136 up-to-date fighters and bombers were sent to the coast off Shanghai.[j][8] The Republic of China Air Force (ROCAF) was just emerging from a loose confederation of aircraft and airmen controlled by individual Chinese warlords. It was a hodgepodge of about 300 land-based fighters, mostly supplied by the US, UK, and Italy, with which to intercept Japanese fighters and bombers. The USSR also began supplying China aircraft after the Sino-Soviet Non-Aggression Pact was agreed in August.
The Curtiss Model 68 Hawk III biplane, built both in the US and China, was used by the ROCAF as a bomber as well as the primary fighter during the early part of the war. It took the brunt of the Japanese attack during the defense of Shanghai and battle of Nanking, helping to make flying aces of several Chinese pilots. Shortly after the conflict began, Gao Zhihang intercepted a land-based Japanese bomber group from Taiwan and shot down a Mitsubishi G3M medium bomber. This was the first aerial combat victory for the Chinese.[9] In addition to Curtiss Hawk IIIs, the ROCAF opposed Japanese attacks with some older Curtis Hawk II, Boeing P-26 Peashooter, Gloster Gladiator, and Fiat CR.32 fighters. After attrition had taken its toll of these aircraft, they were replaced by Soviet Polikarpov I-15 biplane fighters and later by Polikarpov I-16 aircraft, the world's first low-wing monoplane fighter with retractable landing gear used in combat. The latter also had 20mm cannons, making it one of the most heavily armed fighters for the period.
For the next three years, IJN and ROCAF pilots fought above Beijing, Shanghai, Nanjing, Wuhan and elsewhere as Japan sought unsuccessfully to subdue China. Sometimes IJN carrier air groups were sent temporarily to land bases. Both air forces suffered defeats and enjoyed victories. Losing ground, the Chinese shifted their capital westward and inland until establishing it at Chongqing in central China. By 1941, Japan held large portions of northern and coastal China but had been weakened by the battles for inland central China. In mid-September 1941, as the IJN began to focus on the possibility of a wider war in the Pacific, it turned over responsibility for the air war over China to the Imperial Japanese Army.[10] Continued resistance by China's National Revolutionary Army led to a war of attrition that tied down large numbers of Japanese troops until the end of World War II in 1945.[11]
United States vs. Japanese carrier aircraft
The design of Japanese carrier aircraft was consistent with their overall strategy of emphasizing the offense in order to win a short war before America's overwhelmingly superior production capacity could be brought to bear. Expecting to face a numerically superior fleet, Japan's strategy envisioned using aircraft to help neutralize this advantage by gradual attrition as the enemy USN fleet approached Japan. This required aircraft with extended ranges and striking power, which in turn meant having them be lighter and faster but with less protection.[12] Accordingly, Japan's Mitsubishi A6M Zero fighter, Nakajima B5N "Kate" torpedo bomber, and Aichi D3A "Val" dive bomber were all lightly-built with weight minimized by not providing cockpit armor to protect pilots or self-sealing fuel tanks to enable them to continue fighting after taking some hits. As a result of having greater range for its aircraft, the IJN would, during 1942, attack from 250 to 300 miles away compared to the USN that would only do so from 200 miles away.[13]
Fighters
At the time of the 1941 attack on Pearl Harbor, Japan had both the world's best fighter and best torpedo bomber. In addition, their aircraft were flown by the world's most extensively trained and experienced airmen,[14] in part due to their engagement since 1937 in the war in China. The A6M Zero was fast, highly maneuverable, and could out-turn and out-climb the USN Grumman F4F Wildcat. Also, when enemy planes were approaching for an attack, it was important for fighters to get off their decks and reach an advantageous altitude quickly. The Zero could climb at 3,000 ft/minute and the Wildcat only 2,300 ft/minute. Experienced Zero pilots were initially very successful against the lower performing Allied aircraft. Over the course of 1942, however, pilots in Wildcats developed aerial combat tactics such as the high-side pass and the Thach Weave. Exploiting these tactics coupled with greater aircraft survivability due to armor and self-sealing tanks, American pilots neutralized the Zero's advantages. Although better USN fighters were introduced later, the Wildcat served throughout the war. Over the course of 1942, Japan's substantial losses of her experienced pilots contributed to the American's gaining an upper hand in fighter combat.[15]
Torpedo bombers
The Nakajima B5N "Kate" torpedo bomber was superior to the obsolete USN Douglas TBD Devastator in speed, rate of climb, and range. Kate torpedoes contributed to sinking USN fleet carriers Lexington (battle of the Coral Sea), Yorktown (Midway), and Hornet (Santa Cruz Islands), all during 1942. Devastator torpedoes contributed to sinking the IJN carrier Shōhō at the Coral Sea, but Zero fighters slaughtered the Devastators at Midway where they attacked without fighter protection. Only six of the 41 Devastators launched returned to their carriers.[16] Though some closed to targets and launched torpedoes (the Mark 13 torpedo), the torpedoes ran deep or failed to explode
Dive bombers
The US had a superior dive bomber in the Douglas SBD-5 Dauntless compared to Japan's Aichi D3A2 "Val".[17] Benefitting from fortunate timing, bombs from the Dauntless sank all four of the Japanese carriers lost at Midway.[k] Nonetheless, the "Vals" served throughout the war and sank more Allied warships than any other Axis aircraft. This included sinking HMS Hermes, the first carrier to be sunk by carrier aircraft.[18]
United Kingdom vs. German and Italian land-based aircraft
Fighters
When war broke out in 1939 in the Atlantic Theater, the RN had only recently reacquired responsibility for their carrier-launched aircraft. For the previous two decades, the Royal Air Force (RAF) had responsibility for all air operations, and development of improved carrier-launched aircraft had been neglected in favor of land-based fighters for the defence of UK and bombers for the offensive. As a result, the RN entered the war with mostly relatively slow, limited range biplane fighters and bombers that were that were inferior to USN and IJN carrier aircraft of the same age.[19] At the time of Britain's evacuation from Norway, her Gloster Sea Gladiator fighters, Fairey Swordfish torpedo bombers, and Blackburn Skua fighter-bombers were also inferior compared to the land-based German aircraft.[20] Nonetheless, the Sea Gladiators did succeed in shooting down a couple of Messerschmitt Bf 110 fighters during the Norwegian campaign in early 1940.[citation needed] Gladiators and Sea Gladiators did take part in the Battle of Britain that autumn, but it was the numerous land-based Supermarine Spitfires and Hawker Hurricanes and their pilots that provided the principal aerial defense for the UK. Sea Gladiators also assisted during the defense of Malta, where the few in operation shot down Italian aircraft. Gladiators were removed from front-line service around Britain by 1941. The more modern, monoplane Blackburn Roc was able to shoot down a Junkers Ju 88 fighter-bomber attacking a convoy in 1940. However, the Roc was no match for German Messerschmitt Bf 109 or Focke-Wulf Fw 190 fighters and could not even perform as well as Britain's own Blackburn Skua. Considered one of the worst fighters of the war, the Roc was, by late 1940, taken out of front line service and consigned to training, target towing, and rescue duties.[21] A more modern monoplane fighter, the Fairey Fulmar, was introduced in 1940 to replace the obsolete Sea Gladiator. It was a two-seat design and was large and less nimble than the Axis fighters it opposed. Nonetheless, while protecting convoys to Malta, Fulmars shot down ten Italian bombers and six Axis fighters. During the war, they provided air cover for the raids on Taranto and Petsamo, protected convoys to Russia, and supported invasions of French North Africa and Italy. Fulmars shadowed the German battleship Bismarck enabling Fairey Swordfish torpedo bombers to catch up with her.[22] The UK upgraded their naval fighter squadrons in 1941 by adapting the highly successful, land-based Hawker Hurricane to carrier use. The Hawker Sea Hurricane performed well while protecting the Malta convoys and, operating from escort carriers, many Atlantic convoys.
Dive bombers
The monoplane Blackburn Skua two-man fighter-dive bomber was introduced in late 1938. It sank the German cruiser Königsberg during the German invasion of Norway; the first major warship sunk by a dive bomber in combat. Skuas provided air cover during the Dunkirk evacuation and served in the Mediterranean. Like the Roc, however, they fared poorly against the higher performance land-based Messerschmitt Bf 109, and were withdrawn from front line service during 1941.
Torpedo bombers
The biplane Fairey Swordfish torpedo bomber, affectionately referred to as "Stringbag" by her aircrews, was introduced in 1936. It was an archaic-looking biplane with cloth-covered wings, open cockpit and fixed landing gear. It had been designed as a torpedo-spotter-reconnaissance aircraft[23] and emerged as the standard naval attack aircraft serving as both a dive-bomber and torpedo bomber.[24] In the first airborne torpedo attack of the war, Swordfish damaged a German destroyer at Trondheim. Later, Swordfish crippled the French battleship Dunkerque during the Attack on Mers-el-Kébir, disabled three Italian battleships during the Battle of Taranto and attacked the German battleship Bismarck through gale-force storms in the Atlantic, ultimately landing the torpedo that doomed her. Swordfish dropped depth charges and laid mines as well as well. The Fairey Albacore was introduced in 1940 to replace the Swordfish. Both were replaced in the front line by the Barracuda, but the Swordfish was retained to serve in anti-submarine and bombardment spotting assignments throughout the war. In the final accounting, the Swordfish destroyed more tonnage of Axis shipping than any other Allied aircraft.[25]
