In the Army, each Anti-Aircraft Artillery (AAA) auto-weapons battalion was authorized a total of thirty-two 40 mm guns in its four firing batteries. In practice firing rates were closer to 80–100 rpm (1.3–1.7 rounds per second), as the rounds were fed into the breech from four round clips which had to be replaced by hand. The overall performance of the 40MM CANNON round is fantastic. machine gun vs. autocannon).All 20 mm cartridges have an outside projectile diameter and barrel bore diameter of 0.787 inches (20.0 mm). Power for the sights was supplied from a 6V battery. Called small arms grenade munitions (SAGMs), they double the lethality of the standard M433 grenade round by adding a small "smart" fuze sensor that detonates in the air to hit targets in cover or behind obstacles. Such guns were used in support of Army divisions to provide swift protection against air attack without the need to unlimber. 40MM Tri-Barrel Cannon Round. Label.

[32], The L/70 is also used by the Indian Abhay IFV which carries 210 APFSDS and high explosive rounds.[33]. A final wartime change to the elevation mechanism resulted in the "QF 40 mm Mark XII". This proved to leave heavy zinc deposits in the barrel, and had to be abandoned. The resulting Mark 1 and Mark 2 weapons were intended for the left and right side of a twin mount, respectively, and were adapted by Chrysler for water cooling. During the Titan Wars, a resourceful Pilot and his support unit tore a 40mm cannon from a stranded mobile infantry carrier, and attached it to his Atlas, replacing his defunct primary weapon. Chrysler engineers also tried to simplify the gun, unsuccessfully, and to take high speed movies to find possible improvements, but this was not possible until near the end of the war. In order to effectively engage these threats, the gun would have to have longer range and a higher rate of fire, thereby increasing the number of rounds fired over the period of an engagement. Two retired L/60s can be seen adjacent the square in Sarsfield Barracks, Limerick. [2] It has a maximum range of 800 meters, exceeding conventional extended range low-velocity variants by up to 375 meters. Bofors has been part of BAE Systems AB since March 2005. Its low weight and compact dimensions combine with a long range and a high rate of fire. The importance of being able to destroy tanks from the air became obvious. Currently these projectile types can be found in Swedish service manuals.[4]. Bofors signed a contract in late 1928. 40MM XD Pro High Performance Shell. This page was last edited on 13 February 2021, at 11:29. Sweden currently operates the Mk 19 grenade launcher (designated 40 mm granatspruta 92 in Sweden) and thus uses the 40 mm high velocity cartridge. Додатне слике. Continued development was needed to turn it into a weapon suitable for production, which was completed in October 1933. [26] It features a casing with a high-low system. 1. [51] The system lacked moving parts and the propellant was electronically primed,[51] allowing for rates of fire up to one million rounds per minute. Never use the 20 grain loading with lead shot! The water-cooled version was used almost exclusively by the U.S. Navy and Coast Guard. Nope", "AC-130W Stinger II - U.S. Air Force > Fact Sheet Display", "AC-130J Ghostrider - U.S. Air Force > Fact Sheet Display", "AMMUNITION 40mm x 365 FOR ANTI-AIRCRAFT GUN 40mm L/70 BOFORS - SDPR - Yugoimport", "L/70 L70 L-70 Bofors 40mm automatic anti-aircraft gun air defence system technical data sheet", "Abhay (Fearless) Infantry Fighting Vehicle (IFV)", Bofors L/70 40mm automatic anti-aircraft gun, "The military situation in the Baltic States", "Finnish "Lighthouse Battleships" at Dieselpunk.org", International Institute for Strategic Studies. If an unprogrammed round is fired, it will detonate on impact. In British army service the Bofors found a highly specialised role: during the North Africa Campaign at the Second Battle of El Alamein, they were used to fire tracer horizontally to mark safe paths for units through the German minefields. Stream ad-free or purchase CD's and MP3s now on Amazon.co.uk. Japan captured a number of Bofors guns in Singapore and put them into production as the Type 5. 40mm grenade launcher ammunition. During this period Krupp purchased a one-third share of Bofors. Above you can see all the parts of the 40mm CANNON round, how it is put together. In 1989 the Royal Netherlands Army acquired 30 Flycatcher systems. This was a simplified, unstabilised mounting based on the American twin mounting Mark I, and was designed for remote fire control. [48] Instead of a casing, the VOG-25 is a caseless ammunition, featuring its propellant in an expansion chamber at the base of the projectile, functioning more like a mortar round than conventional cased ammunition. 105mm C76A1 KE; 105mm M456A2 HEAT-T; 105mm M490 TP-T ; 105mm M724A2 TPDS-T; 120mm IM HE-T™ 120mm KE-W A1® 120mm M1002 TPMP-T; 120mm M1028 Canister; 120mm M865 TPCSDS-T; Close; Artillery. Leave your comments and thoughts below. This would be a normal configuration for lead shot or flechette darts. The 40mm Bofors Anti-Aircraft Gun is a flak cannon used for anti-aircraft purposes. : Présentation; Pays France et le Royaume-Uni: Type Canon automatique: Munitions: obus de 40 mm - cartouche de 65 × 255 mm Fabricant BAE Systems et Nexter: Poids et dimensions; Masse (non chargé) 340 kg Longueur(s) No 2875 Squadron RAF Regiment, employing the L60, became the first unit to shoot down a jet aircraft, a Me 262, with ground-based anti-aircraft fire, at Helmond in the Netherlands on 28 November 1944. [29], 40×51mm MV (medium velocity),[2] also known as 40×51mm Extended Range Low Pressure (ERLP),[30] is a NATO-standard[31][32] high-low grenade launcher cartridge meant for hand-held grenade launchers. The build quality is better. Bofors considered either updating the 40 mm, or alternately making a much more powerful 57 mm design. By the end of World War II, jet aircraft had so increased the speed of attack that the Bofors simply could not get enough rounds into the air to counter the aircraft before it had already flown out of range. Mark IV: a tri-axially stabilized twin mounting copied from, and usually known as, the "Hazemeyer". A licence was acquired and the gun was converted from metric to imperial measurements. Although the L/60 was later replaced in production by the L/70, it remained in front-line service well into the 1980s. Their first examples were air-cooled versions quickly adapted to ships during the withdrawal from Norway. TL;DR: It depends. The new cannon fires 40mm Cased Telescoped ammunition, manufactured for the British Army by BAE Systems’ munitions factories in Washington, Tyne and Wear and Glascoed in Wales. In 1979 the Royal Netherlands Air Force acquired 25 KL/MSS-6720 Flycatcher radar system and upgraded 75 of their 40L70s to create 25 firing units for static air base defence. Until the early 80s L/70 guns guided by D7B radars were in widespread use in the anti-aircraft role in the German Navy and German Air Force until replaced by Roland SAMs. Probably somewhere between "I bet that didn't hurt for long" and "You have some... Arzt... on you." The new cannon fires 40mm Cased Telescoped Ammunition – the first of its kind in the world – offering a number of benefits to users: Fire power The new cannon delivers up to four times the power of the 30mm round it replaces. Two additional legs folded out to the sides, and the platform was then leveled with hand cranks. Check out 40mm Cannon Round Version 2 by Digiffects Sound Effects Library on Amazon Music. The L/60 continued in use in the Irish Army until recent years, when it was retired in favour of the radar-controlled L/70. [11] After the war, the 3"/50 caliber gun Mark 27 twin mount began to replace the Bofors, because the "VT" proximity fuse would not fit a 40mm projectile, and the 40 mm weapon was considered inadequate against the emerging anti-ship missile threat. II high-explosive shell as well as the M81A1 armor-piercing round, which was capable of penetrating some 50 mm of homogeneous armor plate at a range of 500 yards. The guns fire at 200 rounds per minute and are fed by a 400-round magazine through 200-round dual feeds. Especially designed for our NEW and UPDATED 40MM Cannon Round! 40MM Tri-Barrel Cannon Round. The propellant has high pressure and gives the projectile an average velocity of 241 m/s (791 ft/s) depending on the ammunition type.[4]. Essentially all US naval mountings were twin or quadruple. [51] Unlike common caseless ammunition and their weapon systems the Metal Storm design lacked a feeding magazine and instead stacked the projectiles in front of each other in the barrel with the propellant in between the projectiles. Each Flycatcher was fielded with two modified Bofors 40L70G guns. Brazilian Marine Corps shooting a Bofors L/70. This practice was further developed during operations in North-West Europe, where bursts of colour-coded tracer were used to define the axis of advance of the different formations in large-scale night attacks. The Vickers Class "S" 40 mm (1.57 in) gun was developed in the late 1930s as an aircraft weapon. The SAGM was to undergo evaluation in July 2015 and, if successful, transition into an official Army program of record by the end of the year. In early World War II, six British Bofors were imported for testing, along with Kerrison Predictor directors, and they proved to be superior in all areas. [13], The Navy's satisfaction with the weapons was demonstrated by their practice of telegraphing Chrysler Corporation with the serial numbers of guns when they shot down an aircraft.[9]. British production started slowly: by September 1939 only 233 equipments had been produced; but by the end of the war total production from British, Canadian and Australian factories was over 19,000. The crew of Royalist appeared to find the STAAG a reasonably effective and impressive anti-aircraft weapon during Operation Musketeer in 1956, off Egypt. The 40mm Cannon. 40 mm grenade (alternative spelling: 40mm grenade) is a common design for grenade launcher ammunition. The Swedish Navy purchased a number of 2 pounder Pom-Poms from Vickers as anti-aircraft guns in 1922.
