The Ordnance QF 95-mm howitzer was a British howitzer built in two versions during the Second World War. The tank howitzer version was accepted for service use, but the infantry version was not.
The Ordnance QF 95-mm tank howitzer was designed to be fitted to some later British tanks so they could lay smoke screens or fire HE or HEAT/Hollow Charge shell against concrete targets like pillboxes in the "close support" of infantry. A HESH round may have been issued after World War II.[citation needed] The 95 mm howitzer used fixed ammunition with a 25lb (11kg) projectile, rather than separate charge and round common for artillery howitzers. The tank howitzer was used to arm the Churchill Mark V and VIII, the Cromwell VI & VIII and the Centaur IV tanks.[3]
The howitzer was built up from a section of a QF 3.7-inch anti-aircraft gun barrel, the breech mechanism of the Ordnance QF 25 pounder field gun/howitzer and the recoil mechanism of the Ordnance QF 6 pounder anti-tank gun.[4] The ammunition came from the QF 3.7-inch mountain howitzer; for tank use the rounds had to be modified so they were 'fixed' rather than separate projectile and propellant.[5] The tank howitzer version was also fitted with a large counterweight at the end of the barrel to help balance the gun. In most regiments, the 95 mm-armed tanks were issued to regimental or squadron HQ troops at the rate of two vehicles per HQ. The only variant of the Centaur tank (a Cromwell tank with a less powerful engine) to see action was the 95mm-armed Mark IV. For the Normandy landings, the Royal Marine Armoured Support Group was formed with an establishment of eighty Mark IVs.
Infantry howitzer
The Ordnance QF 95-mm infantry howitzer was a version built as a conventional towed artillery piece. Perhaps in response to the success of the German sIG 33, a proposal was circulated in the summer of 1942 by the British Army for an infantry howitzer for direct fire against concrete structures, like pillboxes.[6] The 95mm tank howitzer already under development was considered to be a logical starting point for the design of the new howitzer. The infantry howitzer version was similar to the tank howitzer, except that it lacked the barrel counterweight and was placed on a box-trail carriage and given a gun shield.[7]
Testing in 1943 showed that the recoil system and the carriage were over stressed and redesign was needed, which delayed testing and introduction of the infantry howitzer until 1944. The problems with the recoil mechanism and carriage were never fully corrected and the weapon was refused by the infantry and declared obsolete in April 1945 after several hundred examples were produced.[8] The decision to reject the infantry howitzer may not have been based entirely on the deficiencies of the gun but due to obsolescence and organisational difficulties. The introduction of the bazooka and recoilless rifles, such as the Burney 3.45-in, may have influenced the decision to refuse the gun since they were lighter, less expensive, portable and fulfilled the direct fire use of the infantry howitzer. There was also the question of who would operate the gun; the infantry already had to support and transport anti-tank guns, anti-aircraft guns, mortars and heavy machine guns. Gun crews would need to be trained and provided with services, such as transport, supply and communications.[9]
The French 75 mm field gun is a quick-firing field artillery piece adopted in March 1898. Its official French designation was: Matériel de 75 mm Mle 1897. It was commonly known as the French 75, simply the 75 and Soixante-Quinze. The French 75 was designed as an anti-personnel weapon system for delivering large volumes of time-fused shrapnel shells on enemy troops advancing in the open. After 1915 and the onset of trench warfare, impact-detonated high-explosive shells prevailed. By 1918 the 75s became the main agents of delivery for toxic gas shells. The 75s also became widely used as truck mounted anti-aircraft artillery. They were the main armament of the Saint-Chamond tank in 1918.
The Ordnance Quick-Firing 17-pounder was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to "up-gun" some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle. As a tank gun, it was succeeded by the 84 mm 20 pounder.
The Ordnance QF 25-pounder, or more simply 25-pounder or 25-pdr, with a calibre of 3.45 inches (87.6 mm), was a piece of field artillery used by British and Commonwealth forces in the Second World War. It was often described as being durable, easy to operate and versatile. It was the major British field gun and howitzer during the War.
The Ordnance QF 18-pounder, or simply 18-pounder gun, was the standard British Empire field gun of the First World War-era. It formed the backbone of the Royal Field Artillery during the war, and was produced in large numbers. It was used by British Forces in all the main theatres, and by British troops in Russia in 1919. Its calibre (84 mm) and shell weight were greater than those of the equivalent field guns in French (75 mm) and German (77 mm) service. It was generally horse drawn until mechanisation in the 1930s.
A tank gun is the main armament of a tank. Modern tank guns are high-velocity, large-caliber artilleries capable of firing kinetic energy penetrators, high-explosive anti-tank, and cannon-launched guided projectiles. Anti-aircraft guns can also be mounted to tanks.
The Ordnance Quick-Firing 6-pounder 7 cwt, or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army. It was also used as the main armament for a number of armoured fighting vehicles.
The Ordnance QF 2-pounder, or simply "2 pounder gun", was a 40 mm (1.575 in) British anti-tank gun and vehicle-mounted gun employed in the Second World War.
The 75 mm gun, models M2 to M6, was the standard American medium caliber gun fitted to mobile platforms during World War II. They were primarily mounted on tanks, such as the M3 Lee and M4 Sherman, but one variant was also used as an air-to-ground gun on the B-25 Mitchell medium bomber aircraft. There were five main variants used during the war: M2, M3, M4, M5 and M6.
This article explains terms used for the British Armed Forces' ordnance (weapons) and ammunition. The terms may have different meanings depending on its usage in another country's military.
The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank gun of the Second World War. It was obtained by boring out the Ordnance QF 6-pounder 57 mm anti-tank gun to 75 mm, to give better performance against infantry targets in a similar fashion to the 75 mm M3 gun fitted to the American Sherman tank. The QF came from "quick-firing", referring to the use of ammunition where the shell has a fixed cartridge. The gun was also sometimes known as ROQF from Royal Ordnance Quick-Firing.
The 3-inch gun M5 was an anti-tank gun developed in the United States during World War II. The gun combined a 3-inch (76.2 mm) barrel of the anti-aircraft gun T9 and elements of the 105 mm howitzer M2. The M5 was issued exclusively to the US Army tank destroyer battalions starting in 1943. It saw combat in the Italian Campaign and on the Western Front in Northwest Europe.
The 7.7 cm Feldkanone 96 neuer Art was a field gun used by Germany in World War I.
The Ordnance QF 4.5-inch howitzer was the standard British Empire field howitzer of the First World War era. It replaced the BL 5-inch howitzer and equipped some 25% of the field artillery. It entered service in 1910 and remained in service through the interwar period and was last used in the field by British forces in early 1942. It was generally horse drawn until mechanisation in the 1930s.
The 8-inch gun M1 was a 203 mm towed heavy gun developed in the United States. At 32,584 m (35,635 yd), it had the longest range of any US Army field artillery weapon in World War II. It was also used in small numbers by the British Army.
The QF 3-inch 20 cwt anti-aircraft gun became the standard anti-aircraft gun used in the home defence of the United Kingdom against German Zeppelins airships and bombers and on the Western Front in World War I. It was also common on British warships in World War I and submarines in World War II. 20 cwt referred to the weight of the barrel and breech, to differentiate it from other 3-inch guns. While other AA guns also had a bore of 3 inches (76 mm), the term 3-inch was only ever used to identify this gun in the World War I era, and hence this is what writers are usually referring to by 3-inch AA gun.
A quick-firing or rapid-firing gun is an artillery piece, typically a gun or howitzer, that has several characteristics which taken together mean the weapon can fire at a fast rate. Quick-firing was introduced worldwide in the 1880s and 1890s and had a marked impact on war both on land and at sea.
The 17pdr SP Achilles is a British variant of the American M10 tank destroyer armed with the British Ordnance QF 17-pounder high-velocity 76.2 mm (3-inch) anti-tank gun in place of the M10's considerably less powerful 3-inch Gun M7. A total of 1,100 M10s were converted to Achilles, making it the second most numerous armoured fighting vehicle to carry the 17-pounder gun, behind the Sherman Firefly tank.
Ordnance QF 3 inch howitzer was a howitzer fitted to British cruiser and infantry type tanks of the Second World War so they could fire a smoke shell in "close support" of other tanks or infantry. HE shells were also available.
The 37 mm Infantry Gun Model 1917 was a light artillery piece produced in the United States during World War I for the French Army. It was adopted by the US Army when it entered the war on the side of the Allies.
