17-pounder in Batey ha-Osef museum, Israel.

The Ordnance QF 17-pounder (or just 17-pdr) was a 76.2 mm 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 equiping a number of British tanks. It was the best Allied anti-tank gun of the war. Used with the APDS shot it was capable of defeating all German armour and the equal of all their guns up to the massive 88/L71. It was used to 'up-gun' some foreign-built vehicles in British service, notably the Sherman Firefly that gave British tank units the ability to hold their own with their German counterparts. In the anti-tank role it was replaced by the 120 mm BAT recoilless gun after the war. As a tank gun it was succeeded by the 20 pounder.

17-pounder, side view.

Although it had not yet entered service, the British predicted that the 6-pounder would soon be inadequate given the increasing armour of German tanks. In late 1940 a design effort was started to create a replacement, and the effort was largely complete by the end of 1941. A prototype production line was set up that spring, and with the appearance of Tiger tanks in North Africa, the first 100 prototype 17-pdrs anti-tank guns were quickly sent off to help counter this new threat in September 1942. So great was the rush that they were sent before proper carriages had been developed, and the guns had to be mounted in the carriages of 25-pounder howitzers. These early weapons were known as 17/25-pounders and given the codename Pheasant. They first saw action in February 1943.

Fully developed 17-pdrs were placed into production in 1943 and were first used during the Italian Campaign. In 1944, the British started to use APDS shot, which travelling at nearly 4000 feet per second (1200 m/s) increased the power of the 17-pdr greatly with a penetration of 213 mm armour (at 1000 m). The Italian Campaign of World War II was the name of Allied operations in and around Italy, from 1943 to the end of the war. ... A shell is a projectile, which, as opposed to a bullet, is not solid but contains an explosive or other filling, though modern usage includes large projectiles without a filling. ...


Initially the HE shell that was developed for the 17 pdr lacked power. This was due to the high powered cartridge - the shell walls had to be thicker to stand the stresses of firing leaving less room for explosive. Reducing the size of the propelling charge for the HE shell allowed the use of a thinner walled and more explosive shell.


The 17-pdr was a much larger weapon then its predecessor. As a result it had to be towed as it could not effectively be moved by its crew alone and needed vehicles such as the Crusader gun tractor) on poor ground and was issued strictly to armour and anti-tank artillery units, and not infantry. General characteristics Length 5. ...


The gun was also quickly adapted for use on various tank chassis, outperforming everything the US or British had. Early attempts to mount it on existing chassis were not terribly successful, but the gun proved so successful on the M4 Sherman that it was quickly rushed into service in time for D-Day as the Firefly. The British also converted some of their M10 Wolverines removing the 3-inch (76 mm) cannon and replaced it with the 17-pdr as well; the resulting vehicles were called Achilles or just 17 pdr M10. The M4 Medium Tank was the main tank designed and built by the US for use in World War II. In the UK lend-lease M4s were dubbed M4 General Sherman after Union General William Tecumseh Sherman, continuing a practice of naming American tanks after famous Generals. ...

The 17 pounder anti-tank guns saw action in Korea, not only against tanks but in general support use against bunker positions.


US Use

The United States Army did not use the 17-pounder in action, although the gun was offered to US forces. US pre-war doctrine was based on using tanks in the infantry-support and exploitation roles, avoiding combat with enemy tanks whenever possible. The role of fighting enemy tanks was tasked to the tank destroyers. Thus the US Sherman mounted much smaller 75 mm weapons, leaving the 3in-armed M10 Wolverine to deal with German armour. In practice this doctrine proved flawed. US tanks ran into their German counterparts all the time, and their smaller guns and lighter armour proved to be a serious disadvantage when facing heavier tanks such as the Panther.

The British success with the 17 pounder did not go unnoticed. In the spring of 1944, Shermans with the new 76 mm gun entered production, with a few hundred available in the UK prior to D-Day. The first 76-mm-armed tanks saw combat during Operation Cobra and became common by the winter. Although the US 76mm was considerably less powerful than the British 17-pounder when firing the most common APC ammunition, when firing HVAP ammunition its performance was adequate against most German armor. The 17-pounder, however, remained the best Allied AT gun. Land on Normandy In military parlance, D-Day is a term often used to denote the day on which a combat attack or operation is to be initiated. ... Operation Cobra was the codename for the World War II operation planned by United States Army General Omar Bradley to break out from the Normandy area after the previous months D-Day landings. ...

Mark V

  • A version of the Mk IV with different mounts to allow it to replace the US 3-inch guns in the M10 Wolverine, creating the Achilles.

Mark VI

  • Another Mk.IV adaptation with a shortened breech.

Mark VII

  • Similar to the Mk.VI, yet another change to the breech.

77 mm HV

  • As the breech-length of the 17-pdr was too long to fit in many tanks a new version was designed with a shorter breech, firing the same projectile as the 17-pdr from a 3-inch 20 cwt AA gun cartridge, along a shortened 17-pdr barrel. This new gun's ammunition wasn't interchangeable with the 17-pounder, so to prevent confusion over ammuntion supplies, it was renamed the '77 mm HV', even though it was the same 76.2 mm caliber as the 17-pdr. This gun was used in the Comet tank.

The A34 Cruiser Comet was a British tank that first saw use near the end of World War II. It is often considered the best overall British tank of the war. ...

The Ordnance QF 6-pounder 7 cwt, or just "6 pdr", was a British 57 mm gun, their primary anti-tank gun during the middle of World War II, as well as the main armament for a number of tanks.
Limitations of the existing 2 pounders were apparent even as the gun was first entering service, and an effort was started to replace it with a much more capable QF weapon starting as early as 1938.
Instead the 6 pounder was followed into service by the next generation British anti-tank gun, the 17 pounder which came into use from February 1943.
