The Japanese Navy similarly used their copy of the FF, designated the Type 99 Mark One cannon on a number of types including the Mitsubishi A6M Zero. 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). The M829A3 uses a more efficient propellant, RPD-380, boosting its muzzle velocity. [2] From patents submitted by Orbital ATK, the penetrator is composed of two sections, an approximately 100-millimeter-long (3.9 in) steel tip and the rest composed of depleted uranium. In 1927 the Oerlikon Swas added to the existing product line. No locking is required, as with such low-power cartridges the static inertia of the bolt or bolt and slide - the physical tendency of heavy components to resist rapid acceleration - is adequate to ensure that the projectile has left the muzzle and the gas pressure in the barrel is down to a safe level before the breech opens (while the bolt spring also resists the opening of the breech, in practical terms its contribution is too small to be relevant). I placed a Pepsi can beside the mag in the last picture so you can see the size of the magazine. During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the Advanced Primer Ignition blowback (API blowback) method of operation. * The 20mm was made famous by Bofors-Oerlikon like platforms. But they and the PIAT were legal to own in those days, ... but a friend's dad was PMST at the USU ROTC unit and he had a Boys .55" anti tank rifle that was a riot to shoot. iMac vs 20mm Anti-Tank Lahti slow motion Richard Ryan Any donations to the channel to help me hire help and make more videos! Allied navies during World War II. [3] The original M829 is no longer in production and has been succeeded by the M829A1, M829A2, and M829A3. The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War.It had a semi-automatic action in a bullpup configuration. Ammunition feed is typically by a 60-round drum magazine on the top of the gun. Just a few weeks before the Fall of France, the Oerlikon factory approved manufacture of their gun in the United Kingdom, under licence. [5] On 20 July 2015, Orbital ATK announced that the M829E4 had passed First Article Acceptance Testing and was entering production. When Germany invaded Poland in 1939 the Polsten design team managed to escape to England. Today the rifles, especially those in working condition, are quite rare and highly sought after. 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. By the time of the Winter War - the Soviet invasion of Finland - anti-tank weaponry for the Finns was in desperately short supply with only a few 20mm and some 13.2mm weapons in circulation. 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. Despite its weight and size, it was appreciated by the troops that used it. Some deactivated (a steel bar welded into the … This powerful round was also credited with some anti-tank capability and so came with AP as well as HE projectiles. The contract includes M829A1 and M829A2 rounds. Oerlikon realized further improvements in rate of fire on the 1SS of 1942, and the 2SS of 1945 which achieved 650 rpm. Buyer responsible for paying for all shipping and transfer costs. The Canadian weapons manufacture… Rated 0 out of 5 $ 3,920.00 Add to cart. The round is specifically modeled for the 120 mm M256 main gun on the Abrams M1A1 and M1A2 main battle tanks. The corresponding training round is the M865 costing $1,121. An improved version known as the 1S followed in 1930. Evaluation would soon enough reveal the 20mm cartridge to be the way of things. A "piece chief" designates targets and the feeder changes exhausted magazines. [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. A trigger in the right-hand grip controls fire. This suggests the steel tip is used to defeat the ERA, with the depleted uranium using to complete the penetration through the vehicle's passive armour. The Oerlikon FF was installed as armament on some fighters of the 1930s, such as the Polish PZL P.24G. 20x145R. The straight sides allows the case to slide back and forward in the cylindrical chamber. The penetrator is carried by a sabot during its acceleration in the gun barrel. 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. Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG),[1] which was incorporated into the Army Research Laboratory (ARL) in 1992. Romania purchased 45 pieces from Germany during the first half of World War II.[6]. Developed as a tank buster, it first saw combat during the Winter War of 1940. It is ironic that forward thinking anti-tank rifle development produced a variety of finely engineered weapons optimized for an outmoded form of warfare. The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War.It had excellent accuracy, penetration and range, but its size made transportation difficult. [2] Although the M829A3 fired from the 44-caliber M256 gun has a lower muzzle velocity than 120 mm shells fired from the Rheinmetall 55-caliber gun barrel or Russian 2A46 125 mm gun ammunition, it uses a larger penetrator with increased mass to increase imparted kinetic energy. However, it had some problems with jamming in the ammunition feed. This variant is unofficially referred to by Abrams tank crews as the "super sabot". In spring 1941 the Solothurn was tested against the .90-cal. The gunner is attached to the weapon by a waist-belt and shoulder supports. It provided a useful increase in firepower over the .50 cal machine gun when adapted and fitted to some aircraft. It uses 8.1 kg (18 lb) of RPD-380 stick propellant, accelerating a 10 kg (22 lb) depleted-uranium rod penetrator, which can be estimated from cutaway mock-ups to be 800 mm (31 in) long, to a muzzle velocity of 1,555 m/s (5,100 ft/s). Projectile length: 780 mm; weight: 9 kg. The 15-round box magazine used by earlier versions of the gun was replaced by drum magazine holding 15 or 30 rounds. During World War II, twin and quadruple Oerlikon mounts were developed, both for army and for navy use. [9], The M829A4 is a fifth-generation APFSDS-T cartridge consisting of depleted-uranium penetrator with a three-petal composite sabot; the penetrator includes a low-drag fin with a tracer, and a windshield and tip assembly. 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. Out of stock. Initially the Oerlikon was not looked upon favorably by the Royal Navy as a short-range anti-aircraft gun. Lahti M39 WW2 20mm Anti Tank Rifle 10 Round Magazine Description: SALE PENDING A World War 2 Finnish Lahti M39 20mm Anti Tank Rifle Magazine that held 10 rounds. In a typical single-barrel naval version, it is free-swinging on a fixed pedestal mounting with a flat armored shield affording some protection for the crew. The propulsion system uses an obturating case base with a semi-combustible cartridge wall. Squadrons in the Far East were equipped exclusively with Oerlikons. Price per 28 round can. 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].

In 1935 it made an important step by introducing a series of guns designed to be mounted in or on the wings of fighter aircraft. It is a technology improvement over the M829A1. Locally produced derivatives of the Oerlikon cannon were used much more extensively, on aircraft, on ships and on land. It has a total weight of 41.1 lb (18.6 kg) and utilizes a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter,[2] which will reach a muzzle velocity of 1,670 meters per second (5,500 ft/s) using of 8.1 kg (18 lb) of JA-2 propellant. Very little is publicly known about the round, perhaps due to export restrictions (see International Traffic in Arms Regulations (ITAR)). Of course that was a lot more money in 1964 than it is now. Today’s article comes to us from, Christopher Bailey, who is particularly interested in finding information and photos of these kinds of antitank weapons. The RAF Regiment made extensive use of Oerlikon guns in the anti-aircraft role. Designated with FF for Flügelfest meaning "wing-mounted", these weapons were again available in the three sizes, with designations FF, FFL and FFS. Developed by the famous Finnish designer Aimo Lahti in 1939, this over-sized rifle soon earned the nickname the “Elephant Gun”. The Oerlikon gun was installed aboard United States Navy ships from 1942, replacing the M2 Browning machine gun, which lacked range and firepower, and largely superseding the 1.1"/75 caliber gun, which was heavier and had less mechanical reliability. 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. The Oerlikon version of the gun was made out of 250 parts: the Polsten was only constructed out of 119 parts. This is a very high quality magazine that has some serious steel in it. The M829A3 is a further improvement, designed to defeat any future armor protection methods like 'Kaktus' ERA, which was seen on the now cancelled prototype tank, the T-80UM2 "Chiorny Oriol" (Black Eagle) tank. It can also be used against enemy troops and weapon emplacements in trenches, field shelters or in brick-wall […] An alternative developed during World War II was the so-called fluted chamber, which had grooves that allowed propellant gas to seep between the chamber wall and the case, taking over the role of the grease.[4]. [6][1] It completed type classification standard in March 2003. Included with sell are 12 unfired brass casings for reloading , Two 10 rd mags with carrier. The M829 is an American armor-piercing, fin-stabilized, discarding sabot tank round.Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG), which was incorporated into the Army Research Laboratory (ARL) in 1992. On 6 May 2014, the U.S. Army announced that it awarded a US$12 million contract to defense contractor General Dynamics for the demilitarization and disposal of 78,000 aging depleted-uranium (DU) tank rounds as newer rounds are added to the U.S. war reserves. 25mm Hotchkiss penetration performance at 30degrees elevation, 100m - 30mm, 500mm - 29mm, 1000m - 20mm The rimmed 25mm Hotchkiss case was used in the light anti-tank Mle 1934 and AFV gun in French service in the late 1930s, (the anti aircraft 25mm Hotchkiss gun had a shorter case 163mm and is rimless, the AA version does not have the same VSB). Used cartridges are ejected from below the breech. The new ammunition's performance gains, while classified, result from several new features. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. In 1927 the Oerlikon S was added to the existing product line. 7191 RARE WW2 GERMAN 28/20mm SQUEEZEBORE ANTI-TANK CARTIRDGE - 28 x 188mm Rimmed with headstamp 2h, avu (maker- Silva Metallwerke GmbH, Werk Genthin), 43 (date), [waffenamt], 2.8 cm Patrh PzB” These were fired in the innovative 2.8 cm schwere Panzerbüchse 41 (sPzB 41) or "Panzerbüchse 41" was a German anti-tank weapon working on the squeeze bore “Gerlich” principle. Introduced in 1939 and rushed into service for the Winter War, the Lahti L-39 fires a 20mm anti-tank round from a top-loaded magazine, and was capable of successfully engaging the Soviet armor of the era. All Oerlikon guns imported from Switzerland, in 1940, were mounted on various gun carriages to serve as light AA-guns on land. This system permits blowback to be used in far more powerful weapons than normal. However, due to delays and then later the Fall of France in June 1940, only 109 guns reached the United Kingdom. This was a Bofors development for their m/40 AA and anti-tank gun. [5], The M829A2 was the immediate response, developed in part to take on this new ERA type. 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. In 1924 SEMAG failed. 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. These features will limit the rate of fire of such guns, unless other steps are taken—as in the final model of the Japanese 99 Mark 2. The neck is not supported while this happens and therefore expands when the case is fired, and the rebated rim allows the face of the bolt, with its extractor claw hooked over the rim, to fit within the chamber. Lahti 20MM [kygunco.com] Have you been searching for the perfect first anti-tank?Look no further than the Lahti L-39. In Germany, Ikaria further developed the FF gun as the MG FF, firing 20x80RB ammunition. [8][9] It was also placed experimentally on the battleships Arkansas, Colorado, Maryland, West Virginia, Washington, Massachusetts, and training ship Wyoming. Left to Right: Boys .55cal w/5-round stripper clip & ammo pouch Solothurn 20mm x 105B, AP-HE-T (Hungarian) Browning .50cal w/ metal link belt The Oerlikon became best known in its naval applications. The weapon was standardized for limited procurement as 20mm automatic gun T3. 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. The M829A3 round has a total mass of 22.3 kg (49 lb) and length of 892 mm (35.1 in). 20MM 20mm Vulcan Electric Primed, brass case AP ammo, linked in original 28 round can. 20mm with suppressor at 2007 Shot Show: 20mm Mag-fed shown in take-down configuration: From left to right:.223, .338 lapua, 50BMG, 20MM Vulcan This ... and ammo was $2.50 per round. The FFL of 30 kg fired a projectile at a muzzle velocity of 675 m/s with a rate of fire of 500 rpm. And the Imperial Japanese Navy, after evaluating all three guns, ordered developments of the FF and FFL as the Type 99-1 and Type 99-2. [4] It costs around $8,500. The new Advanced Combustible Cartridge Case is similar to previous models but has a relocated skive joint placement for better crew-member safety during handling. The 20mm is probably the most versatile round ever used while generally being the smallest/entry level diameter of any weapon deemed “cannon” for past century. The first guns were delivered to the Royal Navy in March or April, 1941. 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]. The initial order for 2,501 M829A4 rounds in 2014 had a unit cost of $10,100 each. The next generation ammunition, called 120 mm APFSDS-T M829A2, entered service in 1994, and is the current armor penetrator ammunition being produced by the General Dynamics Ordnance and Tactical Systems for the 120 mm M256 gun of tanks M1A1 and M1A2. A modern Oerlikon cannon (Oerlikon 20mm/85 KAA) on a Royal Navy warship, "The Machine Gun", Volume4, George M.Chinn., page 12. 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. [2], The M829A1 (nicknamed the "Silver Bullet" by Operation Desert Storm tank crews) proved itself in 1991 against Iraqi T-55 and T-72 tanks during Operation Desert Storm. This, plus the use of new composites for the sabot, which, together with a new propellant, provide superior penetrator performance. The Polsten 20mm automatic loading cannon was a low cost development of the Swiss made 20mm Oerlikon auto-cannon, that was simpler and much cheaper to build than the original without reducing its effectiveness. A post WW2 round with a steel caseing. The purpose of this development was to improve the performance of the gun as an anti-tank and anti-aircraft weapon, which required a higher muzzle velocity. Prototypes were built and tested in late 1942 and operationally deployed on several Elco PT Boats in the Mediterranean. May 1, 2013 Ian McCollum Anti-Tank Rifles 44. The Solothurn S 18-1000 was a Swiss-built 20 mm Anti-Tank rifle which was an upgraded version of the earlier S 18-100. The US Navy operated a quad mount developed for PT boats by Elco Naval Division, Electric Boat Company, called the Elco "Thunderbolt" Mount. The Oerlikon firm, named after the Zürich suburb of Oerlikon where it was based, then acquired all rights to the weapon, plus the manufacturing equipment and the employees of SEMAG. The Solothurn firearms company was owned by the German firm Rheinmetall, who used the Swiss company to manufacture arms which were prohibited for manufacture by any German firm under arms limitations imposed at the end of the First World War. The round is specifically modeled for the 120 mm M256 main gun on the Abrams M1A1 and M1A2 main battle tanks. Similar German installations of the MG FF were not successful. Combined, these features increase the muzzle velocity of the M829A2 approximately 100 m/s greater than the M829A1 (up to approximately 1,675 m/s), while operating at slightly lower pressure. In France, Hispano-Suiza manufactured development of the FFS as the Hispano-Suiza HS.7 and The Royal Navy managed to smuggle out the necessary drawings and documents from Zürich. The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. This beautiful Finnish made, semi-automatic, war proven 20MM uses 10 round inverted box magazines and weighs a moderate 109 pounds. During sustained firing, the magazine must be frequently changed, reducing the effective rate of fire. During the first half of 1939 a contract for 1,500 guns was placed in Switzerland. [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. Several of the rifles remained in service after World War II serving as an anti-helicopter weapon, while many others were sold to collectors, mostly in the United States. This is an inert example of a 30 mm anti aircraft/ anti tank round. The 1930s were a period of global re-armament, and a number of foreign firms took licenses for the Oerlikon family of aircraft cannon. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (Seebach Maschinenbau Aktien Gesellschaft) based near Zürich. SKU: 00020-004. It cost 1/5th of the price to produce. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. T4 automatic gun. The FF weighed 24 kg and achieved a muzzle velocity of 550 to 600 m/s with a rate of fire of 520 rpm. 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. [11] On 12 October 2015, Orbital ATK announced the round had recently received type classification as the M829A4, and was awarded a full-rate production contract to begin in early 2016. 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. The Lahti L-39 is a Finnish 20mm anti-tank rifle used during World War II. 20MM 20mm Vulcan Electric primed, brass case API ammo, loose, Price Each. According to Jane's, the M829 is capable of penetrating 481 mm (18.9 in) of RHA steel armor at up to a 2,000 m (2,200 yd) range. Unfired, British, 1951 Dated Kynoch made Masden 20x120 Ball Round. Later in the war, they also equipped fighters including the Zero with the Type 99 Mark Two, a version of the more powerful and faster-firing Oerlikon FFL. Three sizes of gun with their different ammunition and barrel length, but very similar mechanisms, continued to be developed in parallel. The gun fired through the hollow propeller hub, this being elevated above the crankcase by the design of the gearing. Lahti set forth to design both a 13.2mm anti-tank machine gun and a 20mm anti-tank rifle. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II , and many versions are still in use today. To ease the motion of the case, the ammunition needed to be greased, which was a drawback of the Oerlikon cannon. [7], The A4 (formerly E4) variant was under development by General Dynamics Ordnance & Tactical Systems and Alliant Techsystems (ATK)[8] until ATK received a $77 million, three-year contract on 11 July 2011 to develop and qualify the M829A4 Advanced Kinetic Energy (AKE) round for the U.S. Army's M1A2 SEP (System Enhancement Package) Abrams MBT. 40/73 mm Round RHEAT-7MA with anti-tank Grenade GHEAT-7MA (Improved, modernized version of Anti-tank Rounds for RPG-7V) The 40/73 mm Round RHEAT-7MA with Anti-tank Grenade GHEAT-7MA is designed for destroying tanks and self-propelled guns and other armoured vehicles. This was on the high end of armor penetration for anti-tank rifles, and the m/42 was able to do this with a weapon weighing just 11.7kg (25 lb) – less than a quarter of a comparable 20mm conventional rifle. [10] Its propellant maintains consistent muzzle velocities across operational temperatures from −25 to 145 °F (−32 to 63 °C). The M829A1 round weighs 20.9 kg (46 lb) and has an overall length of 984 mm (38.7 in). It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II, and many versions are still in use today.[2][3]. The 7.9 kg (17 lb) of JA-19 propellant creates a chamber pressure of 5,600 bars (81,221 psi), which results in a muzzle velocity of 1,575 m/s (5,170 ft/s). It was used on a limited scale as an aircraft gun on Luftstreitkräfte warplanes, and an anti-aircraft gun towards the end of that war. There was an earlier Type 94 AA gun which used even larger (20x158) ammunition, but this saw very little use before being replaced by the Type 98. Finnish built Lahti Anti Tank Rifle. Japanese Type 97 20mm Anti-tank Rifle Japanese Type 97 20mm Anti-tank Rifle. Such armament was installed on the Morane-Saulnier M.S.406 and some other types. O 1163 - O 1163 DEACTIVATED INERT. This is a unfired British Kynoch made Masden 20x120 ball round for the Masden 20mm automatic cannon developed in Denmark in the 1920s for the 20mm Madsen automatic cannon, offered in various mountings for aircraft, AA and anti-tank use, although only successful in the … Nevertheless, compared to guns with a locking mechanism a fairly heavy bolt must be employed; while to give this heavy bolt sufficient forward speed, a large spring is required (and Oerlikons, distinctively, have this component wrapped around their barrels.) As a result when firing occurs, the forward force of the bolt and spring acts against the force of the propellant gases until the latter overcome the former and start pushing case, bolt and spring backwards. Different nations and services operated a number of mounting types for the same basic gun. This was capable of perforating 40mm of perpendicular armor plate at 100m (a high explosive projectile was also made). The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. The M829 is an American armor-piercing, fin-stabilized, discarding sabot (APFSDS) tank round. Maximum effective range is 3,000 m (3,300 yd). DEACTIVATED INERT. The cannon is aimed and fired by a gunner using, in its simplest form, a ring-and-bead sight. Belt-fed versions of the gun were developed to overcome this limitation. 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. The shell is designed as a conical cavity with a copper lining, behind which is placed an explosive charge. The production of the first British-made Oerlikon guns started in Ruislip, London, at the end of 1940. Although less powerf… Source: Sa Kuva Non-locking, simple blowback designs are commonplace in much lighter weapons, such as small-caliber semi-automatic pistols.

It was largely superseded by the Bofors 40 mm gun and the 3"/50 Mark 22 gun. The effective target range is 3,000 m (3,300 yd).[4]. 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. 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). 20mm semi auto , Model 39-44 , Comes with the original skies ,barrel shroud , muzzle brake with cover also shoulder rest. [citation needed] Resulting muzzle energy is 12.1 MJ (8.9 million ft⋅lbf). In API blowback weapons, the firing pin fires the cartridge while the bolt is still traveling forward so that the gas pressure has to overcome the forward momentum of the bolt as well, before it can push it to the rear. It is carried in the gun tube by a three-piece aluminum sabot, which separates into three "petals" soon after the round leaves the gun tube. Consulta los ejemplos de traducción de anti-tank round en las frases, escucha la pronunciación y aprende gramática. The French firm of Hispano-Suiza was a manufacturer of aircraft engines, and it marketed the moteur-canon combination of its 12X and 12Y engines with a H.S.7 or H.S.9 cannon installed between the cylinder banks.
