Behind the main chamber was the rear section of the torpedo. The pure oxygen torpedo was first deployed by the IJN in 1935. The main shaft had an inner and outer drive shaft and drove coaxial double four-bladed screws, contra-rotating so as not to rotate the torpedo. Some had only one 8.8cm/30 gun while others had a single 10.5cm/45 gun - but some had both originally. As with all Oerlikon variants, the Type 99 action was blowback with advanced primer ignition. A pressure regulator reduced the decreasing pressure of compressed gas in the air chamber to the constant lower pressure needed to keep the torpedo running at constant speed. This artillery piece was used during the Second Sino-Japanese War and World War II.. [Source]. The Type 99 was not an outstanding weapon. The engine used second type air gas, a code name for 98% pure, high-pressure oxygen—the word "oxygen" was not used for secrecy. Výrobca: FineMolds. The Type 93 torpedo suffered from problems with this gyro speed when launched from a warship steaming at its top speed of around 65 kilometres per hour (35 kn). The Type 93 torpedo had a main chamber filled with pure compressed oxygen, a joint regulator valve preventing reverse flow, and a small (approximately 13-liter) high-pressure air tank. 30 rounds With a total weight of about 42 kilograms and total length of 1.4 meters, the Type 93 was a very big weapon that was quite immobile. A depth meter controlled the running depth. (1.410 m) [one source says 1.597 m] Barrel Length: 39.5 in (1.003 m) Rifling Length: N/A: Grooves (8) 0.006 in deep (0.15 mm) Lands: N/A: Twist: Uniform RH 1 in 32 1: Chamber Volume: N/A The second type air gas (oxygen) was stored at 225 atm (3,310 psi) in a 980 l (260 US gal) main chamber made by machining a block of nickel chromium-molybdenum steel, an alloy first developed for battleship armour. The water pressure board of the torpedo was manually set to five metres, to set the running depth at five metres below the surface, and controlled the side stabilizer to run at that depth. It is the equivalent of the USA's M2 HMG , the British Vickers and the German Stationary MG 34 . Ammunition: 1,000 x 0.30 caliber ammunition 2,000 x 6.5mm ammunition.

The Type 93 was originally made for use by the Japanese Navy marine units of the Special Naval Landing Forces. (42 kg) Gun Length oa: 55.5 in. Besides the US Army wartime publication, there is no evidence this "light tank" or tankette existed. The practical use of the oxygen engine was top secret in the Imperial Japanese Navy. Japan The first prototype was constructed in 1932, and was accepted into service two years later. Range was developed for aerial use for the Imperial Japanese Navy before World War II.It was the standard hand-held machine gun in multi-place IJN aircraft during the most part of the Pacific War.It proved to be seriously inadequate. Quickly realizing the superiority of this design in terms of range and firepow… As with the type 81 and 87, some had only one 8.8 cm/30 gun while others had a single 10.5 cm/45 gun and some had both originally. Rear Admiral Jungo Rai explained this weapon in the chapter "Torpedo", in collective work The Full Particulars of Secret Weapons（秘密兵器の全貌, first published by Koyo-sha, Japan, in 1952. First type air gas, a code name for air compressed to 230 atm (3,400 psi),[b] from a 13.5 l (3.6 US gal) tank, was used to start the engine. Type 93 saw extremely wide use in Imperial Japanese Navy but was also used by the Imperial Army as a stand-alone heavy machine gun (primarily in anti-aircraft emplacements) or equipped on vehicles, such as Type 92 Tankettes. During the Battle of Nanjing in the Second Sino-Japanese War, Japanese forces captured a number of German-made SK c/30 anti-aircraft guns from the National Revolutionary Army of the Republic of China. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the Nelson-class battleships. The Allied warships expected that, if torpedoes were used, they would be fired from not more than 10 km (11,000 yd), their own typical torpedo range. The gyro was started when the torpedo was launched. It was based on the Oerlikon, for which the Japanese had negotiated a manufacturing license in 1936, but it was continually improved and refined. As American air strikes against IJN ships became more common, captains of destroyers and cruisers under air attack had to decide whether or not to jettison torpedoes to prevent them from being detonated during the attack. As such, it was typically mounted on ships and other stationary anti-aircraft positions. It was intended to supersede the Type 14 105 mm cannon in front line combat service. The Type 94 was developed in order to replace the antiquated type 41 Mountain Gun. In-box reviews. Anti-Aircraft Gun Type 93 was a class of U-boats built during World War I by the Kaiserliche Marine.. 13.2 mm There were two more controlling air tanks of total capacity 40.5 l (10.7 US gal) containing air compressed to 230 atm (3,400 psi), to operate the rudders and stabilizers of the torpedo. The Japanese Navy invested heavily in developing a large, heavy, and long-range torpedo, the Type 93. A 45 cm (17.7 in) version, the Type 97, was later developed for midget submarines, but was not a success, and was replaced operationally by Japan's standard aerial torpedo, the Type 91. The Imperial Japanese Navy initially tested the torpedoes at Dainyu, Aga-Minami of Kure city, Hiroshima prefecture, Japan, but the long-range Type 93 torpedo called for a relatively large area for launching tests. The Type 93 was a 610 mm -diameter torpedo of the Imperial Japanese Navy, launched from surface ships. It is commonly referred to as the Long Lance by most modern … "Long Lance" redirects here. History and development. Type 93 torpedo, recovered from Point Cruz. Type 93 U-boats carried 16 torpedoes and had various arrangements of deck guns. , The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. Škála: 1:350. The gyrocompass guided the torpedo to the target, allowing even rear-launched torpedoes to turn around and hit a target in front. The Type 94 Mountain Gun was a mountain artillery piece used by Japan during World War II. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet. 1935 Torpedoes were the only weapon that gave small warships, such as destroyers, the potential to cripple or sink battleships. It could fire a 13.2 mm round at a vertical range of up to 4,000 meters. Its long range, high speed, and heavy warheads provided a formidable punch in surface battles. A disadvantage of the Type 93 was that it was far more likely to detonate due to shock than a compressed-air torpedo. Šiuo metu turimas kiekis yra sandėlyje! Japanese Navy Type 93 or Japanese Army Type Ho twin 13mm heavy machine gun, seen in US Technical Manual TM-E 30-480: Handbook on Japanese Military . 450 rpm Total length The Type 93 had a maximum range of 40 km (44,000 yd) at 70 km/h (38 kn) with a 490 kg (1,080 lb) high explosive warhead. These torpedoes used an otherwise normal wet-heater engine burning a fuel such as methanol or ethanol. After the number of American warships was sufficiently reduced, the IJN would commit its own presumably fresh and undamaged battleships to finish off the U.S. remnants in one huge climactic battle. The Type 93 debuted in 1933 and was quickly put to use against Chinese forces during the Second Sino-Japanese War (1931-1945). This sometimes occurred when USN cruisers chased IJN destroyers breaking away from the scene of the battle at high speed during the night, or when American fleet carriers, engaged in flight operations, were targeted by IJN submarines in the South Pacific in 1942–43. The Type 93 weighed about 2,700 kg (6,000 lb), with a high explosive warhead of about 490 kg (1,080 lb). The same Samar engagement saw the heavy cruiser Suzuya sunk by the detonation of her own Type 93 torpedoes: a bomb near miss starboard amidships set off the torpedoes in the starboard tube mounts; the resultant fires propagated to other torpedoes nearby and beyond; the subsequent explosions damaged one of the boilers and the starboard engine rooms and eventually reached the main magazines. We don't know about any in-box reviews for this IJN Type 93 13mm Twin Machine Gun Set (#IMP-35009R1) from INFINI Model. Type 93 rev.1 torpedo was equipped with an oil-fueled twin-cylinder reciprocating engine. Subsequently, the test range at Otsu shima Island, Tokuyama city, Yamaguchi prefecture, next to Hiroshima prefecture was used. Some specification examples of ranges by speed: However, the IJN announced officially the maximum performance of the Type 93 was 11 km (12,000 yd) at 78 km/h (42 kn). The front of the torpedo contained the warhead, behind which was the shell of the 12 mm (0.47 in) thick main chamber. The capabilities of the Type 93 went mostly unrecognized by the Allies until examples were captured intact in 1943. There were bevel gears on the shaft. The Type 92 is a light machine gun and not to be confused with the similarly named Type 92 Heavy Machine Gun. The Type 93 HMG is a stationary weapon featured in Battlefield V. Added with the War in the Pacific Tides of War chapter, the weapon is the standard emplaced machine gun of the Japanese faction. The torpedo needed careful maintenance. As the compressed air was consumed and lost pressure, high-pressure oxygen was supplied from the main chamber through the joint valve into the compressed air tank. Check out my video sponsor Omaha Bricks' awesome designs! The IJN armed nearly all of its cruisers with Type 93 torpedoes. Predpokladaný dátum odoslania: utorok, 15.9.2020 Viac informácií na tému dostupnosti a dáta doručenia. The Type 92 7.7mm machine gun (九二式七粍七機銃, Kyūni-shiki nana-miri-nana kijū?) The boats had various arrangements of deck guns. While the Type 93 was approximately 9 m (30 ft) long and 61 cm (24 in) in diameter, the second type air main chamber was 348 cm (137 in) long, occupying more than a third of the total length of the torpedo. TM-E 30-480, Handbook on Japanese Military Forces. Eventually, the IJN's weapons development engineers found that by starting the torpedo's engine with compressed air, and then gradually switching to pure oxygen, they were able to overcome the problem of explosions that had hampered it before. Caliber Type 93 Machine Gun Mastelis: 1:350. It has also been incorrectly referred to as a Type 92, when the "right designation is Type 93". The outer shell of the torpedo was made of steel panels 3.2 mm (0.13 in) thick, but 1.8 mm (0.071 in) thick at the rear, welded and water-tight. 13 mm/76 (0.52") Type 93 (Model 1933) Ship Class Used On: Almost all warships of World War II: Date Of Design: 1933: Date In Service: about 1936: Gun Weight: 92.6 lbs. Compressed oxygen is dangerous to handle and required lengthy research and development, not to mention additional training for the warship's torpedomen, for safe operational use. The Kaiten had a range of 23,000 m (25,000 yd) at 56 km/h (30 kn), and 70,000 m (77,000 yd) at 22 km/h (12 kn). The U.S. Navy's doctrine, presuming an invasion by Japan of the Philippines (an American commonwealth at that time), called for the battle line to fight its way across the Pacific Ocean, relieve or recapture the Philippines, and destroy the Japanese fleet. The Type 93 overall looked and functioned very similarly to its counterpart, larger caliber anti-aircraft weapons such as the Type 96 Autocannon. Early marks were known simply as E-shiki ("Oerlikon Type") guns, and it was not until 1941 and 1942 that the Mark 1 and Mark 2 were so designated. Produkto kodas: fin-WZ04.
