Type 5 Cannon
The 30 mm Type 5 cannon was a Japanese Navy autocannon used near the end of World War II. It was an indigenous 30 mm design with better performance than the Navy's earlier Oerlikon-derived Type 2 or the Imperial Army's Browning-derived Ho-155, although it was considerably heavier. The Type 5 was to have become the standard fighter cannon of the Japanese Navy – four would have been mounted on the J7W Shinden – but by the end of the war had seen use on only a few aircraft, including variants of the Mitsubishi J2M and Yokosuka P1Y. Specifications *Caliber: 30 mm (1.2 in) *Ammunition: 30 × 122 (345 g) *Weight: 70 kg (155 lb) *Rate of fire: 350 rounds/min Cannon was constructed by engineer Masaya Kawamura, in Nihon Tokushu-Ko KK, and produced in Navy factories in Toyokawa and also in small numbers KK Nihon Seikojo and Nihon Tokushu-Ko KK.

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoil Operation
Recoil operation is an operating mechanism used to implement locked breech, autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas. The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lay dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs viable.

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. The most common ammo capacity typically carried on a man-portable weapon system vary from 50 to 300 rounds. Variants Feed strip 8mm Lebel feed strip on an M191 ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...

Type 2 Cannon
The 30mm Type 2 cannon was a Japanese Navy autocannon used during World War II. It was a scaled-up version of the 20mm Oerlikon FF The FF were a series of 20mm autocannon introduced by Oerlikon in the late 1920s. The name comes from the German term ''Flügel Fest'', meaning ''wing mounted, fixed'', being one of the first 20mm guns to be small and light enough to fit into a fi ... cannon.

Ho-155 Cannon
The 30 mm Ho-155 cannon was a Japanese aircraft autocannon used during World War II, often mistakenly called with the Ho-105 or Ho-151. A lighter and more compact Ho-155-II was designed towards the end of the war. Development The Ho-155-I was first began development in 1942 as a scaled-up and modified version of the 20mm Ho-5 cannon, itself a scaled-up Model 1921 aircraft .50-inch Browning machine gun. In 1943-44 began development of the Ho-155-I and in late 1944 began the development and production of the Ho-155-II for fit into tighter wing bays of fighter planes such as the Ki-84-Ic, Ki-102 and on the project design of the jet-powered Ki-201.

Kyushu J7W
The Kyūshū J7W ''Shinden'' (震電, "Magnificent Lightning") was a World War II Japanese propeller-driven prototype fighter with wings at the rear of the fuselage, a nose-mounted canard, and pusher engine. Developed by the Imperial Japanese Navy (IJN) as a short-range, land-based interceptor, the J7W was a response to Boeing B-29 Superfortress raids on the Japanese home islands. For interception missions, the J7W was to be armed with four forward-firing 30 mm type 5 cannons in the nose. The ''Shinden'' was expected to be a highly maneuverable interceptor, but only two prototypes were finished before the end of war. A jet engine–powered version was considered, but never even reached the drawing board. Design and development In the IJN designation system, "J" referred to land-based fighters and "W" to Watanabe Tekkōjo, the company that oversaw the initial design. The idea of a canard-based design originated with Lieutenant Commander Masayoshi Tsuruno, of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi J2M
The Mitsubishi J2M ''Raiden'' (雷電, "Lightning Bolt") is a single-engined land-based fighter aircraft used by the Imperial Japanese Navy Air Service in World War II. The Allied reporting name was "Jack". Design and development The J2M was designed by Jiro Horikoshi, creator of the A6M Zero, to meet the 14-Shi (14th year of the Showa reign, or 1939) official specification. It was to be a strictly local-defense interceptor, intended to counter the threat of high-altitude bomber raids, and thus relied on speed, climb performance, and armament at the expense of manoeuvrability. The J2M was a sleek, but stubby craft with its oversized Mitsubishi Kasei engine buried behind a long cowling, cooled by an intake fan and connected to the propeller with an extension shaft. Teething development problems stemming from the Kasei engine cooling system, and the main undercarriage members led to a slowdown in production. A continual set of modifications resulted in new variants being introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yokosuka P1Y
The Yokosuka P1Y ''Ginga'' (銀河, "Galaxy") was a twin-engine, land-based bomber developed for the Japanese Imperial Navy in World War II. It was the successor to the Mitsubishi G4M and given the Allied reporting name "Frances". Design and development The P1Y was designed by the Yokosuka Naval Air Technical Arsenal to Navy specification 15-''Shi'', calling for a fast bomber with speed matching the Zero, range matching the G4M, a 907 kg (2,000 lb) bombload, and the ability to dive-bomb as well as carry torpedoes. As the result, the construction suffered from excess complexity, difficulty of manufacture, and poor serviceability. Problems with the availability of enough reliable Nakajima ''Homare'' engines led to their replacement by the Mitsubishi ''Kasei'' in the P1Y2-S night-fighter version. The streamlined design of the ''Ginga'' is attributed to Miki Tadanao, an engineer who after World War II went on to create a similar aerodynamic design for Japan's earliest ...

Type 99 Cannon
The Type 99 Mark 1 machine gun and Type 99 Mark 2 machine gun were Japanese versions of the Oerlikon FF and Oerlikon FFL autocannons respectively. They were adopted by the Imperial Japanese Navy (IJN) in 1939 and served as their standard aircraft autocannon during World War II. Adoption In 1935, officers in the Imperial Japanese Navy began to investigate 20 mm automatic cannon as armament for future fighter aircraft.Robert C. Mikesh, ''Zero'', Motorbooks USA, 1994. Their attention was drawn to the family of aircraft autocannon manufactured by Oerlikon, the FF, FFL and FFS. These all shared the same operating principle, the advanced primer ignition blowback mechanism pioneered by the Becker cannon, but fired different ammunition: 20×72RB, 20×101RB, and 20×110RB, respectively. Following the import and evaluation of sample guns, the Imperial Japanese Navy decided in 1937 to adopt these weapons. To produce the Oerlikon guns, a group of retired Navy admirals created a new ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
