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. It was certainly silent, but the light, round-nosed bullet quickly lost velocity, limiting the maximum range. Furthermore, Americans also captured certain number of PTRD from Viet Cong in Vietnam War. This is launched at an extremely high muzzle velocity and is capable of penetrating 40mm of armour at 1,000m. Hi, recently saw an episode of "Cajun Pawn Stars" which featured a Boys Rifle in 50 cal. Alternative Titles: anti-tank weapon, antiarmour weapon Antitank weapon , any of several guns, missiles, and mines intended for use against tanks . While proving highly effective in anti-tank artillery, such projectiles never saw service in AT rifles. This should not be confused with the Czech PzB 41 already referred to. At any rate, armies still find it worthwhile providing AP projectiles for HMGs and modern versions of the AT rifle. It was a Mauser design (similar to the MG 151) which fired at 900 rpm, weighed 22.5kg, was 174cm long and had a 100cm barrel. The British Army recently selected the .338 Accuracy International as the L115A1. The Rifle, Anti-Tank, .55in, Boys, commonly known as the "Boys Anti-tank Rifle" (or incorrectly "Boyes"), was a British anti-tank rifle in use during the Second World War. Anti-tank rifle received a shutter made on the basis of the decisions of the Gew.88 and Gew.98 projects. It deals armor piercing damage, capable of inflicting substantial damage to armored vehicles like Light Tanks, Half-tracks and the Landing APC.While it is decent against unarmored vehicles it is not effective against buildings. The anti-tank rifle was born in World War 1 but saw its key evolution during the fighting of World War 2. Another type of special-purpose large-calibre weapon is the silenced sniping rifle. The alternative approach to achieving improved penetration was simply to increase the calibre. This rifle has a unique history as it was originally classified as a "Short Barrel Rifle" by the ATF in 1968. A barrel chambered for the Russian 14.5X114 cartridge is available when greater effective range is required. Guns captured by the Germans were given the designation 14.5 mm PzB 783(r). The Lahti L-39 is a Finnish 20mm anti-tank rifle used during World War II. Given that the thickest armour on contemporary British tanks measured just 12mm, the gun was quite effective. Armour rapid development of a considerably more powerful penetration was midway between the two Soviet, 14.5 x 114 cartridge, with armour penetration leap- rounds. The Boys Anti-tank Rifle was an early attempt to stop Axis tanks and armored vehicles during World War II. Nearly all of them used existing cartridges developed for aircraft or AA use and also used similar mechanisms, although usually semi rather than fully automatic. Despite the small-calibre cartridge, the guns were not particularly light. Armour penetration of the tungsten-cored bullet was very similar to the Polish round (30mm/100m/90°) but it was available in a variety of weapons: the PzB 38, PzB 39 and M.SS41. Even the best of the weapons was only marginally effective against early Second World War tanks and AT riflemen soon found that they had to wait until they were suicidally close, or until they could shoot at the thinner side armour. surrounding the nomenclature of this weapon, as it. The 15mm vz 41, the Mauser in that their first effort, the Sholoklov M39, was simply a Mauser copy chambered for their 12.7X108 heavy machine gun round. The guns are made with CW base with some ATOW stuff for the attachements. Very rare WW2 PIAT Anti tank weapon. Chambered in the original .55 caliber. The solid bullet was still round-nosed but was twice the weight of the De Lisle s, which in conjunction with its higher muzzle velocity extended its useful range. The Mauser 13 mm anti-tank rifle (German: Tankgewehr M1918, usually abbreviated T-Gewehr) is the world's first anti-tank rifle —the first rifle designed for the sole purpose of destroying armored targets—and the only anti-tank rifle to see service in World War I.Approximately 15,800 were produced. 01 November '20. Anti Tank rifles were the first attempt at stopping a tank with a portable weapon, quick to reload and "easily" carried by one man. [citation needed] During the initial invasion, and indeed throughout the war, most German tanks had side armor thinner than 40 mm (Panzer I and Panzer II: 13-20 mm, Panzer III and Panzer IV series: 30 mm, Panzer V Panther (combat debut mid-1943): 40-50 mm). They seemed like a good idea during the rearmament boom of the mid- to late 1930s, offering the power to defeat most contemporary tanks in a package handy enough to make them infantry weapons, but no sooner had the fighting started than the deficiencies became apparent. Source: Wikimedia Entries are listed below in alphanumeric order (1-to-Z). However, the firm also offered anti-tank 44kg. 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. Little then happened until the mid-1930s, when much experimentation resulted in the Boys Rifle, a bolt-action weapon of brutally functional appearance, chambered for a new .55" (13.9 x 99B) round, 500" Godsal experimental (Courtesy: MoD Pattern Room), which was similar in dimensions to the .50" sophisticated semi-automatic gas-operated weapon. The performance of these weapons was, by most accounts, significantly better than the .55" Boys or the 12.7mm Sholoklov. The L6 Wombat version was greatly lightened through the use of magnesium alloys. after some abortive experiments in 1939^0, two Panzerbusehe round, but the original was supplied very different guns to fire it. Surplused out in the 1950s and 60s, many will remember the vintage ads where you could buy these out of the back of American Rifleman Magazine. None was adopted. SEE WEBVERT FOR FULL DETAILS 077491 34810 Enfield Guns Webvert. These are chambered for special cartridges based on commercial hunting ammunition, modified to take bullets which are very heavy for their calibre and highly streamlined to retain as much velocity and range as possible. The cartridge was used in several experimental machine guns but was not adopted until it was necked out to 20mm, in which form it became the 20 x 102 round used in the M39 and M61 Vulcan aircraft cannon. The first combat use of anti-tank rifles took place during the Invasion of Poland of 1939. In 1939 the USSR captured several hundred Polish Model 35 anti-tank rifles, which had proved effective in the September Campaign when Poland was invaded by Germany. It was relatively fragile and expensive and far less common than Degtyarevs, The cartridge was available in two service AP rival PTRD. The Bofors fired the company's own long, rimmed 20 x 145R cartridge and was mounted on a tripod. Henry C. Boys in 1936 and produced from 1937 to 1940 by RSAF Enfield, Birmingham Small Arms and John Inglis and Company. In practice, the maximum before reaching the artillery category was around 20mm and weapons in this class were developed and adopted by several nations. The next attempt was an experimental American weapon tested in Vietnam. more effective, but came too late for service use. The rifle was the main anti-tank weapon of an infantry platoon. It was similar in principle to the De Lisle but chambered for a much more effective cartridge, the specially developed .458 x 1V" Barnes (11.5 x 38B), which was made by shortening the .458" Winchester Magnum big-game round. The gun was a gas-operated semi-automatic weapon designed to be fired from a low tripod. This concern might have lain behind the rather optimistic addition to the base of the Patronen 318 cartridge of a small tear-gas capsule. It was often nicknamed the "elephant gun" by its users due to its size and large bore. Discribtion: Anti Tank Rifles are not sniper rifles, they are inaccurate highpowered rifles used to stop light armored vehicles shooting one from the hip or rapid fire will mostly result in missing the target. As we have seen, the British and Soviet AT rifles were in a direct line of development from the Mauser M1918 in that they retained a similar calibre (12.7-15mm) and often used cartridges shared with HMGs. Boys Anti-Tank Rifle Ask Each Other. While the artillery got the 2 pounder, a cheaper, lighter alternative was needed for the Infantry to help deal with tanks and other armored vehicles. Hotchkiss AT gun, but the French weapon was much bigger and heavier, and definitely out of the AT rifle class. Even the 13mm Mauser was adequate to deal with the great majority of tanks in service in the 1930s, most of which were only designed to keep out standard rifle ammunition. WW2 PIAT Anti Tank Weapon . Anti-Tank Rifles Solothurn S18-1000: The Pinnacle of Anti-Tank Rifles October 13, 2017 Ian McCollum 40. The gun is a simple bolt-action weapon weighing 26kg and can be broken down into two sections for easier carrying. This Anti-Tank Rifle Was “Noted for Its Uselessness” in World War II. To illustrate this, a typical 7.9mm AP bullet of 14.3g has a sectional density ratio of .32 while a 20mm projectile of 150g has an SDR of .53, and (projectile shapes being equal) the SDR is directly, 7.92 mm M.SS 41 (Courtesy: MoD Pattern Room), related to the ballistic coefficient which determines, The SI8-100 was replaced by the much larger the velocity loss; the higher the SDR, the lower the S18-1000, chambered for the long 20 x 138B, The first of the AT cannon was developed from German AA cannon, the FlaK 30 and 38. Precision shooting is possible at 1,500m, with the maximum effective range being around 2,000m. The .55" Boys round was actually the subject of various attempts to design a machine gun around it (by Vickers and Rolls-Royce, and even in Italy!). The first solution saw the Spitzgeschoss mit Kern, more commonly called the K Bullet, being issued in larger quantities. It also featured a large muzzle brake of distinctive shape, in an attempt to reduce recoil to manageable levels. The 15.2 x 114, The USA developed the largest of the HMG-, .55" Boys rifle (Courtesy: MoD Pattern Room). The 20 x 125 cartridge was a large and powerful item and the gun used a gas-unlocked delayed blowback mechanism similar to the Hispano s. Provision was also made for the barrel and receiver to recoil in order to steady the weapon. Later in the war a 45.5g tungsten-cored shot was massive cartridge incorporated automatic breech developed which was fired at 945 m/s. The MG 141 was reportedly produced in small numbers, but the barrel wear, bad enough in the single-shot rifles, must have been extremely severe. The French had some massive heavy tanks in service and the first of the British infantry tanks, the A11 (better known as the Matilda 1), boasted armour up to 60mm thick. Such weapons are also useful in disposing at a safe distance of unexploded battlefield ordnance such as mines, and they are even attracting interest as vehicle-mounted HMG replacements in circumstances in which weight is at a premium. The barrel was reduced in length from 117cm to 58cm and fitted with a cup to take two different shaped-charge projectiles. One of the lesser-known advancements in military technology is the anti-tank rifle. Designers in Germany and Poland were aware that penetration was improved much more by increases in striking velocity than it was by increases in projectile weight or calibre. Selbstladegewehr, or heavy self-loading rifle. These weapons were mainly deployed by the Italian Army but also saw service with Switzerland and the the aircraft and AA guns). The Anti-Tank Rifle (ATR) is an elongated weapon that is effective at suppressing armored vehicle attacks. The M1918 was conceptually very simple: a bolt-action weapon just like a scaled-up infantry rifle but 1.68m long and weighing 17.7kg. The relatively low velocity limited its TJw 2Qmm mti_tank uke Ms So!othurn Sl8-1000, effectiveness, although it was still capable of were too heavy to pick up and carry penetrating over 30mm/100m/90°. Each infantry company and cavalry squadron was to be equipped with three rifles, each operated by a team of two soldiers. The PTRS (Protivotankovoe Ruzh 'ye = antitank rifle) of 1941, a Simonov design, was a class AT rifles, the T1E1 Cal .60". The problem was that to follow the conventional route and increase the calibre of AT rifles would result in a significant increase in the size, weight and recoil of the weapon, thus greatly reducing its usefulness to front-line troops. www.militaryarmyshop.com . AA cannon. Finland has produced the Helenius 20mm APH RK20 using the old ShVAK rimmed cartridge, while Croatia has developed the semi-recoilless RT20 AMR around the 20 x 110 HS 404 cartridge; part of the gun gas is ducted backwards, over the gunner's shoulder. Rifle includes 49 rounds of the original .55 cal ammunition. Even in standard cruiser tanks, frontal armour of up to 30mm was beginning to appear. It was expensive to make and soon replaced by the simplified, manually operated PzB 39. It was rushed into service to provide infantry with some protection against the Allied tanks until the TuF could be introduced. The Soviet Union paid even greater homage to this class was Czechoslovakia. This enabled the use of more powerful cartridges as well as a much shorter lock time for more accurate shooting. Description: Boys Anti Tank rifle! After the Soviets produced heavier tanks, it was quickly relegated to the anti-truck role. service as the PzB 41. However, reports that the gun could fire full-auto are incorrect; the armourers manual for the gun shows no means of achieving selective fire and the Japanese nomenclature is Jidoho (autoloading gun) instead of Kikanho (automatic cannon). The guns were relatively compact but heavy. A less extreme approach to long-range sniping is offered by rifles designed around the .338" Lapua Magnum cartridge (8.58x71), such as the Accuracy International bolt-action and the Barrett Model 98A autoloader. It was bought by Hungary and Finland, the version for the latter being known as the S18-154. They were fitted to light armoured vehicles as well as available in a shortened version for paratroops. Efficient recoil-reduction techniques make the new weapons much lighter and handier than the old AT rifles, at around 10-16kg. 1 History 2 Design Details 3 Gallery 4 Trivia 5 References The weapon was designed by Edwin Pugsleyduring World War I in 1918, with the patent having been awarded in early December of that year. Solothurn also developed 20mm guns, but these fired from a locked breech and were derived from the Erhardt aircraft cannon first conceived in the First World War. This gun's claim to fame is that it was available with an armoured shield which helped to raise the travelling weight to 68kg. Although unable to penetrate the frontal armor of German tanks, it could penetrate the thinner sides of early-war German tanks as well as thinly armored self-propelled guns and half-tracks. Apart from the need to fit a large silencer to the barrel (or preferably design the barrel with an integral silencer) it is also necessary to hold the muzzle velocity down to subsonic speeds of around 320 m/s in order to avoid the revealing 'crack' of a supersonic bullet passing by. Surprisingly, it fired from an open bolt, but this must have been useful later when a fully automatic version was adapted for AA use. These weapons extend the accurate sniping range from about 850m for 7.62 x 51 NATO sniping rifles out to 1,400+m. SEE WEBVERT FOR FULL DETAILS 0036 309 729 174 Berta Istvan Webvert. The other Swedish weapon was the exception to the rule and the most remarkable of the European AT rifles, the 20mm Carl Gustav m/42 recoilless. A simpler development with a similar purpose is the South African Mechem NTW 20/14.5 AMR. Vasily Degtyaryov copied its lock and several features of the German Panzerbüchse 38 when hasty construction of an anti-tank rifle was ordered in July 1941. In 1939 the USSR captured several hundred Polish Model 35 anti-tank rifles, which had proved effective in the September Campaign when Poland was invaded by Germany. The gun was long and heavy, however, and was not popular in service. By the 1930s the a far more powerful weapon which was capable of design had been developed by Oerlikon and was penetrating 40mm at short range. As tank armour rapidly increased in thickness, the AT rifles could not keep up. Originally, these steel core armored piercing bullets had been issued so that frontline units could tackle enemy pillboxes an… Neither rifle appears to have seen service. It could penetrate an armor plate up to 35 to 40 mm (40 mm with tungsten ammunition) thick at a distance of 100 meters at 0 degrees. Flag images indicative of country of origin and not necessarily the primary operator. It was of bullpup design (with the magazine behind the pistol grip) and manually operated by rotating and sliding the grip. These weapons' combination of portability and. fed by a five-round clip. The main conclusion in studying the history of AT rifles is that they were a considerable waste of time and resources. Out of this necessity came the Rifle, Anti-Tank, .55in, Boys. The cartridge is therefore simply gigantic, with a case 180mm long and with a rim diameter of 48mm. In German hands, production concentrated ing from 10mm to 30mm (both at 100m/60°), and on a version modified to accept the 7.92X94. The Japanese also adopted the 20mm calibre for their only AT rifle, the Type 97. US forces have deployed more than one type of .50" calibre rifle in recent years, particularly those by Barrett and Harris, and at least thirty other nations have also purchased quantities of rifles of this type. A Boys Mk.1. Most of the rifles use standard HMG ammunition, but there are some exceptions. The first of these was similar to the PTRD in that the barrel recoiled, automatically ejecting the spent cartridge, which was manually replaced. The calibre may be only a fraction less than the 25mm. 35 anti-tank rifle was extensively used by most Polish units. In comparison with the smaller calibres, the more powerful 20mm cannon suffered disadvantages of size, weight and recoil (requiring at least two men to handle them) but benefited from less sensitivity to range; small projectiles tended to lose velocity, and therefore penetration, at a much higher rate.
