countries used theirs in active or reserve service until about the 1970s and ammunition for the weapon is currently being produced by Pakistan Ordnance Factories. Initial production was slow, but by 1945, over 12,000 had been manufactured. The 25-pounder was probably the most outstanding field artillery piece used by British and Commonwealth forces in the Second World War, being durable, easy to operate and versatile.


Design

The design was the result of extended studies looking to replace the 18-pounder ( bore) field gun and the 4.5-inch howitzer (114.3 mm bore), which had been the main field artillery equipments during the
First World War World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fightin ...
. The basic idea was to build one weapon with the high velocity of the 18-pounder and the variable propelling charges of the howitzer, firing a shell about halfway between the two in size, around of about . Development during the inter-war period was severely hampered by a lack of money and it was eventually decided to build a new design from existing 18-pounders by converting barrels but designing a new barrel and carriage for production when funds were available. The result was a weapon firing a shell weighing . It was mounted on late model 18-pounder carriages. One of these used a circular firing platform and this was adopted for the new guns. The firing platform was attached to the gun and when lowered the gun was pulled onto it. This platform transferred most of the recoil forces to the ground, instead of using the spade at the end of the trail, making the gun very stable when firing. It also provided a smooth flat surface for the carriage to rotate on using the road wheels, this enabled the gunners to traverse the carriage quickly in any direction. Unlike the 18-pounder, the 25-pounder used howitzer-type variable-charge ammunition. The 25-pounder was separate-loading; the shell was loaded and rammed, then the cartridge in its brass case was loaded and the breech closed. In British terminology, the 25-pounder was called "quick firing" (QF), originally because the cartridge case provided rapid loading compared with bag charges, and was automatically released when the breech was opened. The use of separate shell and cartridge allowed the charge to be changed for different ranges. For the Mk 1 Ordnance on an 18-pounder carriage there were three "charges", charges one, two and three, all of which could be used in the common cartridge design. The Mk 2 Ordnance on Mk 1 carriage added a "super" charge in a different cartridge. In 1943 a separately bagged "increment" charge was added; used with the Super it provided higher velocity for anti-tank use. The introduction of the increment to super was only possible following the addition of the

in the previous year. Subsequently, another type of increment was introduced to be added to charges one and two to provide additional combinations for use in high angle fire. However, this fire required a dial sight adaptor, removal of the platform and some excavation of the ground. In common with all British guns of the period the indirect fire sight was "calibrating". This meant that the range, not elevation angle, was set on the sight. The sight compensated for the difference in the gun's muzzle velocities from standard. The gun was also fitted with a direct-fire telescope for use with armour-piercing shot. It also used "one-man laying" in accordance with normal British practice. An important part of the gun was the ammunition trailer ("trailer, artillery, No 27"). The gun was hooked to it and the trailer hooked to the tractor for towing. The gun did not need a limber and could be hooked directly to a tractor. The trailer provided the brakes as only a hand-brake was fitted to the gun carriage. The trailer carried ammunition; thirty-two rounds in trays (two rounds per tray) in the trailer protected by two doors. Ammunition was also carried in the gun tractor with the detachment and various gun stores. Some stores, such as sights, were carried cased on the gun. Each section (two guns) had a third tractor that carried ammunition and towed two ammunition trailers. The gun detachment comprised the following: No 1 – detachment commander (a sergeant) No 2 – operated the breech and rammed the shell No 3 – layer No 4 – loader No 5 – ammunition No 6 – ammunition, normally the "coverer" – second in command and responsible for ammunition preparation and operating the fuze indicator The official "reduced detachment" was four men.

Many different companies manufactured the guns and component parts in the UK.

in Glasgow were some of the most significant. The various Royal Ordnance factories produced most of the ordnance components. In Canada, Sorel Industries built complete guns and provided the ordnance for fitting to the Sexton. Australia also built complete guns, choosing to weld the carriages rather than rivet, as was the practice in the UK and Canada. In all, over 13,000 were made worldwide.


Ammunition

The 25-pounder fired "separate" or two-part ammunition – the projectile was loaded separately from the propelling charge in its (usually brass) cartridge case with its integral primer. Typically for a quick-firing gun, the cartridge case provided

. There were two types of cartridge. The normal cartridge contained three cloth charge bags (coloured red, white and blue). White or blue bags would be removed from the cartridge to give "charge one" or "charge two", leaving all three bags in the cartridge case gave "charge three". The cartridge case was closed at the top with a leatherboard cup. The second type of cartridge was "super", which provided one charge only. The cup could not be removed from the cartridge case. In 1943, an incremental charge of of cordite ("super-plus") was introduced to raise the muzzle velocity when firing

to be fitted. Adoption of "upper-register" (high-angle) fire needed more charges to improve the range overlap. This led to the development of the "intermediate increment" of 4oz cordite, which was introduced in 1944. The bags were striped red and white to indicate that they should only be used with charges one and two. When one bag was used with charge 1 it provided charge 1/2. When one was added to charge 2 it provided charge 2 1/3, and two bags, charge 2 2/3. This allowed a range of seven different charges instead of four. There were many marks of cartridge, mostly differentiated by propellant type. Double-base propellant (

and colonial infantry and armoured divisions of all types during the Second World War. It was also used by the RAF Regiment in North Africa. Throughout the war, each British-pattern infantry division was established with 72 25-pounders, in three field artillery regiments. Armoured divisions were eventually standardised with two field artillery regiments, one of which was self-propelled (see below). Before mid-1940, each regiment had two batteries of twelve guns; after that date, regiments changed to batteries of eight guns and added a third battery, a process that was not completed until early 1943. In the late 1950s, the British Army reverted to batteries of six guns. Field artillery regiments had two batteries of 25-pounders and one of 5.5 inch guns. The early 18- and 25-pounders had been towed in the field by the

These were manufactured by Morris, Guy and Karrier in England, and, in greater numbers, as the Canadian Military Pattern field artillery tractor by Ford and Chevrolet in Canada. In the 1950s, the British Army replaced the various "quads" with a new Bedford three-ton gun tower fitted with a specialist body. In 1941, the British Army improvised a self-propelled 25-pounder named the

tank chassis. By Second World War standards, the 25-pounder had a smaller calibre and lower shell-weight than many other field-artillery weapons, although it had longer range than most. (Most forces had entered the war with even smaller designs but had quickly moved to and larger weapons.) It was designed for the British practice of suppressive (neutralising) fire, not destructive fire that had proved illusory in the early years of the First World War. Nevertheless, the 25-pounder was considered by all to be one of the best artillery pieces in use.

Service with other nations

In addition to Commonwealth and colonial forces, other Second World War users included the free forces of France, Greece, Poland, Czechoslovakia, Netherlands, Belgium and Luxembourg. The first shot fired by US artillery against the German army in the war was from a 25-pounder of the 34th Infantry Division. After the Second World War, 25-pounders remained in service with many Commonwealth armies into the 1960s. They were used in Korea by British, Canadian and New Zealand regiments and in Malaya by British and Australian batteries. They also featured in wars on the Indian sub-continent and in the service of Israeli and other Middle Eastern armies.


Australia

Australia used the 25-pounder extensively, including in WW2, Korea and the Malayan Emergency. They were kept in use by reserve units up until 1970s. Individual guns are now often seen as fixed memorials in memorial parks and Returned Servicemen's clubs. Because of the rough terrain involved in the New Guinea campaign, the heavy nature of the weapon made it difficult to use. The gun was manufactured in Australia, which also made it available for use in Australian developed vehicles, including a light tank, the Chassis 160, the

New Zealand

During World War II New Zealand Gunners of 2nd New Zealand division made extensive use of the 25-pr in Greece, North Africa and Italy. The 16th Field Regiment of the Royal New Zealand Artillery, equipped with 25-pounders, was formed to join the United Nations force in the Korean War. The 25-pdr was replaced in first-line units by the OTO Melara L5 gun. The guns were withdrawn from operational service with Territorial Force Artillery by 1977. Today, 25-pounders remain in service as ceremonial gun.

Variants


Mark I

Known officially as the "Ordnance, Quick Firing 25-pounder Mark I on Carriage 18-pr Mark IV", or "Ordnance, Quick Firing 25-pounder Mark I on Carriage 18-pr Mark V" and commonly called the "18/25-pounder". The Mark I was a 25-pounder barrel and breech in the modified jacket of an 18-pounder gun, as a 'loose liner'. The jacket provided the interface to the 18-pounder carriage. The earliest versions retained 18-pounder type elevation sights but later ones had Probert pattern calibrating sights on the right side of the saddle. The Mark IV P, carriage was a box trail, Mark V P, was a

. These conversions of the 18-pounder first entered British service in 1937. A few were lost in the Norwegian campaign and 704 in France, leaving about the same number in UK's global stocks. They served in North Africa (until about late 1941) and India. This mark of 25-pounder was limited to charge 3 due to its 18-pounder carriage.


Mark II

The Mark II, fitted to the Mark I carriage was the standard gun during the war. They were built in Australia and Canada but mostly in UK. Deliveries (from UK production) started at the beginning of 1940 and first entered service with a Canadian regiment stationed in UK during May 1940. No Ordnance 25-pr Mk 2 on Carriage 25-pr Mark 1 were lost in France. This gun fired all charges, 1 – 3 and Super. In 1942, a muzzle brake was fitted to the gun to eliminate the instability caused when firing the 20 lb AP shell with Charge Super at direct fire low elevation angles. To preserve the gun's balance on the trunnions, a counterbalance weight was also fitted, just in front of the breech ring. The designation of the modified gun was not changed. Eventually, all guns serving in Europe were so converted. The Mark II ordnance had six main marks of the barrel: ;Mark I barrel :Original variant with a loose liner. ;Mark II barrel :The standard design, also made in Canada as C Mk II barrel. ;Mark II/I :In 1946, a programme was introduced to modify the gun's breech ring by morticing the rear corners. A corresponding modification was made to the rear corners of the breech block. This was to reduce the instances of cracking the ring. ;Mark III barrel :The Mark III barrel was a Mark II with a modified receiver to prevent the rounds from slipping back out when loading at high angles. It was introduced in January 1944. ;Mark III/I :This was a Mk III gun with the same modification to the ring and block as for the Mk II/I. ;Mark IV barrel :The Mark IV was identical to the Mark III/I, and featured the modified ring and a paired block from new. ;Mark VI barrel :The final alteration of the breech ring made in 1964.

Carriages

;Mark I :The Mark I carriage was the first real 25-pounder carriage. Later in the war, some guns had a double spacer-separated shield to improve protection. It had Probert-pattern calibrating sights, but with the range indicator wrapped into the distinctive cone that rotated against a fixed reader arm. ;Jury axle :In

transport aircraft. ;Mark II The Mark II carriage was basically the War Office-approved formalisation of the Jury Axle version of the 25-pounder. Changes included a narrower shield, a new narrower track platform (No 22), and modified Jeep wheels. ;Mark III The Mark III carriage, also narrow, was a further development of the Mark II carriage to provide joints that enabled the trail to be cranked for "upper register" (high-angle) fire to avoid the need to dig a trail pit, and used with the cranked "dial sight adaptor" previously adopted for high-angle fire. It entered service soon after the war. High-angle fire had been introduced in Italy and used increments to charges 2 and 3 to give the 25-pounder seven charges. ;Mark IV The British did further work on the Australian-designed short 25-pounder, enabling it to fire charge Super. One or two prototypes were produced and the carriage was officially designated the Mark IV, but never went into production.
