The Polsten was used as a substitute for the Oerlikon in the same roles, one of which was as an airborne unit anti-aircraft gun, used in Operation Market Garden . Bofors signed a contract in late 1928. Designated with FF for Flügelfest meaning "wing-mounted", these weapons were again available in the three sizes, with designations FF, FFL and FFS. The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the most powerful 20 mm rounds in existence. This gun used a 400-grain (26-gram) charge of IMR 4831 smokeless powder to propel a 2,000-grain (130-gram) projectile at 2,800 feet (850 meters) per second.[5]. Close. For close-range defense Archons are equipped with a 20mm remotely operated chaingun. This system permits blowback to be used in far more powerful weapons than normal. The water-cooled version was used almost exclusively by the U.S. Navy and Coast Guard. Prototypes were built and tested in late 1942 and operationally deployed on several Elco PT Boats in the Mediterranean. level 1. This fired a still larger cartridge (20x110RB) to achieve a muzzle velocity of 830 m/s (versus 490 m/s for the original Becker 20x70RB gun), at the cost of increased weight and a reduced rate of fire (280 rpm). To facilitate this, the Oerlikon's chamber is longer than needed to contain the cartridge, and the front-end of the bolt, which is the same diameter as the case, actually enters this extended chamber behind the cartridge before firing. [8][9] It was also placed experimentally on the battleships Arkansas, Colorado, Maryland, West Virginia, Washington, Massachusetts, and training ship Wyoming. The Germans fielded the unrelated early 2 cm Flak 28 just after World War I, but the Treaty of Versailles outlawed these weapons and they were sold to Switzerland. I have to do serious research to obtain accurate information. 25mm Single Autocannon Mount ; Improvement Cost: 10 10 10 â

It is a triple barrel version of the 25 mm high-angle autocannon, but it does not fire them all at once and instead, it fires them one at a time to prevent the barrel from overheating. share. Each of the four mounted guns had a separate magazine that held only 20 rounds. The Oerlikon FF was installed as armament on some fighters of the 1930s, such as the Polish PZL P.24G. The quad 1.1-inch gun (nicknamed the âChicago Pianoâ) proved to be equally disappointing and frequently jammed. The gun was eventually abandoned as a major anti-air weapon due to its lack of stopping power against heavy aircraft and against Japanese kamikaze attacks during the Pacific War. This is a simple Opel Blitz truck with the flatbed modified to carry a quad 20mm autocannon for use against aircraft and soft targets. And the FFS, which weighed 39 kg, delivered a high muzzle velocity of 830 m/s at a rate of fire of 470 rpm.[4]. Generally similar to the C/30, the main areas of development were the mount, which was fairly compact. We don't know about any in-box reviews for this US Navy 20mm Single Autocannon & Quad 1.1-inch AA Gun (#WA19) from FineMolds. The gunner is attached to the weapon by a waist-belt and shoulder supports. [4], This unique chamber and bolt design necessitates the use of a characteristically shaped cartridge: the case has straight sides, very little neck, and a rebated rim. An improved version known as the 1S followed in 1930. A handful of corvettes were fitted with the weapon toward the end of the war, but it appeared more commonly on frigates and destroyers at the time. [3] Other kinds then in existence included numerous practice rounds (marked Übung or Üb. In the air, the Ikaria MG FF was used as armament on a number of German aircraft, of which the most famous is the Messerschmitt Bf 109. This is a compilation of my firing the Oerlikon over a two day shoot. Their first test gun was a re-⦠The gun went into service in 1944, and was used well into the 1950s, among other uses, on Cromwell tanks[citation needed] and early model Centurion tanks. manually aimed by a gunner. Even as the Flak 30 was entering service, the Luftwaffe and Heer (army) branches of the Wehrmacht had doubts about its effectiveness, given the ever-increasing speeds of low-altitude fighter-bombers and attack aircraft. For the FF series drum sizes of 45, 60, 75 and 100 rounds were available, but most users chose the 60-round drum. All Oerlikon guns imported from Switzerland, in 1940, were mounted on various gun carriages to serve as light AA-guns on land. GOOD FILM - Flug(zeug)abwehrkanone air defense gun; anti-aircraft artillery (AAA) of the German army used in an anti -tank role Note: Prices and availability are indications only. In 1924 SEMAG failed. The 1930s were a period of global re-armament, and a number of foreign firms took licenses for the Oerlikon family of aircraft cannon. Production started in 1941 and entered service in 1942. These were the principal armament for its Light Anti-Aircraft squadrons in North Africa, the Middle East, Italy, and North Western Europe, until the introduction of the Bofors 40/L60 40mm gun from 1943, although many squadrons retained a mix of guns until the end of World War 2. [7] In contrast, 20mm cartridges are far too powerful, and efficient autocannon barrels too long, for this basic system to be practical; so the Oerlikon uses Advanced Primer Ignition (API) to augment the resistance of the bolt. The cannon is aimed and fired by a gunner using, in its simplest form, a ring-and-bead sight. The Half-track s⦠A modern Oerlikon cannon (Oerlikon 20mm/85 KAA) on a Royal Navy warship, "The Machine Gun", Volume4, George M.Chinn., page 12. A 20mm cannon-firing North American M61 Vulcan in real-life. Squadrons in the Far East were equipped exclusively with Oerlikons. The Flakvierling weapon consisted of quad-mounted 2 cm Flak 38 AA guns with collapsing seats, folding handles, and ammunition racks. SEMAG continued development of the weapon, and in 1924 had produced the SEMAG L, a heavier weapon (43 kg) that fired more powerful 20×100mmRB ammunition at a slightly higher rate of fire, 350 rpm. Based off of a French designed 25 mm autocannon, this was a twin barrel version of the domestically produced 25 mm High-angle Autocannon. The Royal Navy managed to smuggle out the necessary drawings and documents from Zürich. Nose fuzed tracer round, self-destruct at 5.5 seconds (2000m range) due to tracer burn-through. Rheinmetall[N 1] responded with the 2 cm Flak 38, which was otherwise similar but increased the rate of fire to 220 RPM and slightly lowered overall weight to 420 kg. When raised, the weapon measured 307 cm (10 feet 1 inch) high. Set-up could be accomplished by dropping the gun to the ground off its two-wheeled carriage and levelling with hand cranks. It is still in use today on some naval units, theoretically as a last-recourse anti-air weapon, but mainly used for firing warning shots or incapacitating small vessels. During World War II and the Korean War, the Battleship New Jersey carried twenty Quadruple 40mm Bofors Gun Mounts (Quad 40s). In 1930 Oerlikon reconsidered the application of its gun in aircraft and introduced the AF and AL, designed to be used in flexible mounts, i.e. The Royal Canadian Navy popularized the use of the Oerlikon gun as an anti-ship and anti-submarine gun - while it was not effective against the armour of most larger ships, it was used extensively and effectively against U-Boats, and on the decks of larger ships. The gun fired through the hollow propeller hub, this being elevated above the crankcase by the design of the gearing. The first guns were delivered to the Royal Navy in March or April, 1941. In Kriegsmarine use, it was fitted to U-boats, Siebel ferries and ships to provide short-range anti-aircraft defence, and was also employed in fixed installations around ports, harbours and other strategic naval targets. Autocannon: Quad Colt Mk.12 (20mm) AAM: R.550 Magic (Infrared) The F-8E Crusader is a French fighter aircraft available to NATO forces. The production of the first British-made Oerlikon guns started in Ruislip, London, at the end of 1940. [1] It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons onto a single carriage. C1A5s are powered by twin hybrid engines, with one engine powering each tread. The Army in particular felt the proper solution was the introduction of the 37 mm caliber weapons they had been developing since the 1920s, which had a rate of fire about the same as the Flak 38, but fired a round with almost eight times the weight. History and Design. This meant that a maximum combined rate of fire of 1,400 rounds per minute was reduced practically to 800 rounds per minute for combat use – which would still require that an emptied magazine be replaced every six seconds, on each of the four guns. Apart from changes to the design of the guns for wing-mounting and remote control, larger drums were introduced as it would not be possible to exchange magazines in flight. It featured a dramatically simplified mount using a tripod that raised the entire gun off the ground, which had the side benefit of allowing it to be set up on an uneven surface. ... Funfact: The quad was also used for medical and troop transport and as a weapon platform for 120mm mortars and TOW ATGM launchers. Indeed, it came as a surprise when Rheinmetall introduced the 2 cm Flakvierling 38, which improved the weapon just enough to make it competitive once again. West German paratrooper Kraka "Quad" with 20mm autocannon. In January 1944, the 21st Army Group decided that only 20 mm Polsten guns would be used as a standard light gun to simplify supply. All through 1937-1938 Lord Louis Mountbatten, then a Captain in the Royal Navy, waged a lone campaign within the Royal Navy to set up an unprejudiced trial for the Oerlikon 20 mm gun, but it was all in vain. Such armament was installed on the Morane-Saulnier M.S.406 and some other types.

The Flakvierling four-autocannon anti-aircraft ordnance system, when not mounted into any self-propelled mount, was normally transported on a Sd. The MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II.Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft.Salvaged guns saw post-war use by other nations. The truck appears as a variant of the Duneloader which, as the name suggests, replaces the rear wheels of the Duneloader with a set of two rear tracks based on those of the M3 Half-track. The Flak 38 was accepted as the standard Army gun in 1939, and by the Kriegsmarine as the C/38. In Germany, Ikaria further developed the FF gun as the MG FF, firing 20x80RB ammunition. It became famous in the naval anti-aircraft role, providing an effective defense at short ranges (in practice up to 1.5 km) at which heavier guns had difficulty tracking a target. CIWS stands for Close-In Weapons System. A wide variety of 20x138B ammunition was manufactured to be used in 2 cm Flak weapons; some of the more commonly used types are listed on the following table. It was not until the Commander-in-Chief of the Home Fleet, Admiral Sir Roger Backhouse, was appointed First Sea Lord that Mountbatten's efforts bore fruit. If the bolt had stopped at the mouth of the chamber as in a simple blowback gun, this momentum would have been neutralized; instead thanks to the continuous movement the momentum acts to counter the propellant gases and slow the rearward travel of cartridge and bolt. Nevertheless, the C/30 became the primary shipborne light AA weapon and equipped a large variety of German ships. Very unusually for a high-powered autocannon, the Oerlikon and its derivatives feature blowback operation: the bolt is not locked to the breech of the gun at the moment of firing. However, due to delays and then later the Fall of France in June 1940, only 109 guns reached the United Kingdom.
