The Mitsubishi 1MF was a Japanese carrier fighter aircraft of the 1920s. Designed for the Mitsubishi Aircraft Company by the British aircraft designer Herbert Smith, the 1MF, also known as the Navy Type 10 Carrier Fighter was operated by the Imperial Japanese Navy from 1923 to 1930.
The Japanese shipbuilding company Mitsubishi Shipbuilding and Engineering Co Ltd set up a subsidiary company, the Mitsubishi Internal Combustion Engine Manufacturing Co Ltd (Mitsubishi Nainenki Seizo KK) in 1920 to produce aircraft and automobiles at Nagoya. It quickly gained a contract from the Imperial Japanese Navy to produce three types of aircraft for operation from aircraft carriers: a fighter, a torpedo bomber and a reconnaissance aircraft. To produce these aircraft, it hired Herbert Smith, formerly of the Sopwith Aviation Company to assist the design of these aircraft, Smith bringing to Japan Jack Hyland and a team of six other British engineers . [1]
The fighter designed by Smith and his team, designated the 1MF by Mitsubishi, and known as the Navy Type 10 Carrier Fighter by the Japanese Navy (referring to the year of design of 1921, the 10th year of the Taishō period), first flew in October 1921. [1]
The 1MF was a single-seat, single-bay biplane with unequal-span wings and all-wooden construction, powered by a 224 kW (300 hp) Hispano-Suiza 8 engine (license produced as the Mitsubishi Hi engine). It was fitted with claw-type arrestor gear for use with British-style fore and aft arrestor cables. [2]
After successful flight testing, the aircraft was accepted by the Japanese Navy as a standard fighter, with 138 of various versions being built, production continuing until 1928. [3]
The 1MF entered service with the Imperial Japanese Navy in 1923, replacing the Gloster Sparrowhawk. [4] A 1MF aircraft became the first aircraft to take-off from and land on Japan's new aircraft carrier Hōshō on 28 February 1923. [2] The 1MF series proved a tough and reliable aircraft, [3] operating from the carriers Akagi and Kaga - as well as from Hōshō - when they entered service in 1927 and 1928 respectively. [2] It continued in service until 1930, being replaced by the Nakajima A1N.

The Aichi B7A Ryusei was a large and powerful carrier-borne torpedo-dive bomber produced by Aichi Kokuki for the Imperial Japanese Navy Air Service during the Second World War. Built in only small numbers and deprived of the aircraft carriers it was intended to operate from, the type had little chance to distinguish itself in combat before the war ended in August 1945.
The Mitsubishi A5M, formal Japanese Navy designation Mitsubishi Navy Type 96 Carrier-based Fighter (九六式艦上戦闘機), experimental Navy designation Mitsubishi Navy Experimental 9-Shi Carrier Fighter, company designation Mitsubishi Ka-14, was a WWII-era Japanese carrier-based fighter aircraft. The Type number is from the last two digits of the Japanese imperial year 2596 (1936) when it entered service with the Imperial Navy.
The Mitsubishi A7MReppū was designed as the successor to the Imperial Japanese Navy's A6M Zero, with development beginning in 1942. Performance objectives were to achieve superior speed, climb, diving, and armament over the Zero, as well as better maneuverability – all parameters that were ultimately achieved towards the end of its development in 1945. However, limitations on Japanese industry towards the end of the war prevented the A7M from ever entering mass production or being deployed for active duty, and it never saw active service. Its allied reporting name was "Sam".
The Mitsubishi F1M was a Japanese reconnaissance floatplane of World War II. It was the last biplane type of the Imperial Japanese Navy, with 944 built between 1936 and 1944. The Navy designation was "Type Zero Observation Seaplane" (零式水上観測機).
The Nakajima A4N was a carrier-based fighter used by the Imperial Japanese Navy, and the last biplane designed by Nakajima. The first prototype was completed in 1934, but due to engine trouble the aircraft did not see service until 1936. Given the Nakajima internal designation Nakajima YM, the Japanese Navy designation was Navy Type 95 Carrier Fighter. A total of 221 were built. It saw combat in the Second Sino-Japanese War in the late 1930s.
The Mitsubishi B5M was an Imperial Japanese Navy Air Service (IJNAS) land-based attack aircraft, originally intended for carrier use. The B5M was also given the long formal designation Navy Type 97 No.2 Carrier Attack Bomber and Allied reporting name of Mabel.
The Nakajima A1N, or Navy Type 3 Carrier Fighter, was a Japanese carrier-based fighter of the late-1920s and early-1930s. It was a licensed copy of the British Gloster Gambet fighter, built by the Nakajima Aircraft Company for the Imperial Japanese Navy. Approximately 150 were built in two versions, the A1N1 and A1N2.
The Mitsubishi B1M was a Japanese torpedo bomber of the 1920s, also known as the Navy Type 13 Carrier-Borne Attack Aircraft. It was designed and built by Mitsubishi and used in combat against China. The aircraft was used by the air services of the Imperial Japanese Navy and Imperial Japanese Army.
The Yokosuka B4Y was a carrier-borne torpedo bomber used by the Imperial Japanese Navy Air Service from 1936 to 1943. The B4Y replaced the Mitsubishi B2M2 and the Yokosuka B3Y, and was the last biplane bomber used operationally by the Imperial Japanese Navy. The Allied reporting name was "Jean".
The Mitsubishi B2M was a Japanese carrier-based torpedo bomber of the 1920s and 1930s. It was built by Mitsubishi to a design by Blackburn Aircraft of Britain and was operated by the Imperial Japanese Navy.
The Mitsubishi Ki-15Army Type 97 Command Reconnaissance aircraft was a Japanese reconnaissance aircraft and a light attack bomber of the Second Sino-Japanese War and Pacific War. It began as a fast civilian mail-plane. It was a single-engine, low-wing, cantilever monoplane with a fixed tailwheel undercarriage; it carried a crew of two. It served with both the Imperial Japanese Army and Navy. During World War II it was code-named "Babs" by the Allies.
The Gloster Sparrowhawk was a single-seat fighter aircraft designed and produced during the early 1920s by the British aircraft manufacturer Gloster.
The Mitsubishi 2MR was a Japanese carrier-based reconnaissance aircraft of the 1920s, also known as the Navy Type 10 Carrier Reconnaissance Aircraft or the C1M in the Navy's short designation scheme. Designed for Mitsubishi by the British aircraft designer Herbert Smith, the 2MR was used by the Imperial Japanese Navy through the 1920s and 1930s.
The Mitsubishi K3M was a trainer built by Mitsubishi which was used by the Imperial Japanese Navy in an extremely wide variety of roles, including light transport, liaison aircraft, utility aircraft and occasionally light bomber. Its Allied reporting name was Pine.
The Mitsubishi Ki-18 was an unsuccessful and unsolicited attempt by Mitsubishi to meet a 1934 requirement issued by the Japanese Army for a modern single-seat monoplane fighter suitable to the needs of the Imperial Japanese Army Air Force. During this competition, Nakajima entered the Nakajima Ki-11, and Kawasaki entered the more maneuverable Kawasaki Ki-10 biplane. The competition was won by Kawasaki, but the new fighter was not accepted by the IJAAF with much enthusiasm.
The Mitsubishi 1MT was a Japanese single-seat triplane torpedo bomber built by Mitsubishi for the Imperial Japanese Navy Air Service. Designed by the former Sopwith designer Herbert Smith it was intended for use aboard the Japanese aircraft carrier Hōshō.
