3-inch gun M5

The 3-inch gun M5 was an anti-tank gun developed in the United States during World War II.

It saw combat in the Italian Campaign and on the Western Front in Northwest Europe.

3-inch anti-aircraft gun M3W
3-inch anti-aircraft gun M3

The 3-inch anti-aircraft gun M3 was an anti-aircraft gun which served throughout the 1930s and possibly into early World War II. Developed from the earlier 3-inch M1917 and 3-inch M1918 guns, it was in the process of being replaced by the time of the US entry into World War II, but was subsequently adapted into an anti-tank gun role, both free-standing and in a self-propelled tank destroyer.

3-inch gun M1903W
3-inch gun M1903

The 3-inch gun M1903 and its predecessors the M1898 and M1902 were rapid fire breech-loading artillery guns with a 360-degree traverse. In some references they are called "15-pounders" due to their projectile weight. They were originally emplaced from 1899 to 1917 and served until shortly after World War II. These 3-inch guns were placed to provide fire to protect underwater mines and nets against minesweepers, and also to protect against motor torpedo boats. In some documentation they are called "mine defense guns". The 3-inch guns were mounted on pedestal mounts that bolted into a concrete emplacement that provided cover and safety for the gun's crew.

3-inch gun M1918W
3-inch gun M1918

The 3-inch gun M1918 was a United States 3-inch anti-aircraft gun that entered service in 1918 and served until it was largely superseded by the 3-inch anti-aircraft gun M3 in 1930, though the M1918 remained with some National Guard units until early in World War II. The M3 was subsequently replaced by the M1 90mm AA gun early in World War II, primarily during 1942. The M3 3" gun was later adapted for the anti-tank role, serving as the main armament of the M10 tank destroyer during World War II.

8 cm FK M. 5W
8 cm FK M. 5

The 8 cm Feldkanone M.5 was a field gun used by Austria-Hungary during World War I. It was a conventional design, with its most notable feature being its obsolescent autofrettaged bronze barrel, necessary because Austria-Hungary still had trouble making steel of the proper quality. Its development was quite prolonged as the Austrians took years to decide on the proper recoil system and type of breech. Even then production difficulties prevented its introduction into service until 1907.

A total of 18,116 pieces were built. On June 22, 1941, the Red Army had 4,708 of these guns. In 1943 the gun was replaced in production by the 76 mm regimental gun M1943, but remained in service until the end of the war.

The gun used a modernized barrel from the 76 mm regimental gun M1927 and the carriage from the 45 mm anti-tank gun M1942 (M-42). The gun was intended for destruction of light field fortifications and openly placed personnel by direct fire. HEAT shells gave it limited anti-armor capabilities. 76.2-mm regimental guns M1943 completely replaced M1927 guns in production that year and were built until the end of the German-Soviet War. Soon after the end of the war the production ceased due to insufficient range and muzzle velocity.

The Ordnance BL 15-pounder, otherwise known as the 15-pounder 7 cwt, was the British Army's field gun in the Second Boer War and some remained in limited use in minor theatres of World War I. It fired a shell of 3-inch diameter with a maximum weight of 15 pounds (6.8 kg), hence its name which differentiated it from its predecessor '12-pounder' 3-inch gun which fired shells weighing only 12.5 pounds (5.7 kg).

BLC 15-pounder gunW
BLC 15-pounder gun

The Ordnance BLC 15-pounder gun was a modernised version of the obsolete BL 15-pounder 7 cwt gun, incorporating a recoil and recuperator mechanism above the barrel and a modified quicker-opening breech. It was developed to provide Territorial Force artillery brigades with a reasonably modern field gun without incurring the expense of equipping them with the newer 18-pounder. It is the gun that writers usually mean by "15-pounder gun" in World War I, but can be confused with the earlier Ordnance QF 15-pounder Ehrhardt or Ordnance BL 15-pounder, both of which fired the same shell.

DavidkaW
Davidka

The Davidka was a homemade Israeli mortar used in Safed and Jerusalem during 1947–1949 Palestine war. Its bombs were reported to be extremely loud, but very inaccurate and otherwise of little value beyond terrifying opponents; they proved particularly useful in scaring away both Arab soldiers and civilians. It is nominally classified as a 3-inch (76.2 mm) mortar, although the bomb was considerably larger.

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 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 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".

Ordnance QF 3-inch howitzerW
Ordnance QF 3-inch howitzer

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. Earlier British tanks were fitted with a 3.7 in howitzer.

It was produced by Armstrong Whitworth, Elswick and used on Royal Navy warships, exported to allied countries, and used for land service. In British service "12-pounder" was the rounded value of the projectile weight, and "12 cwt (hundredweight)" was the weight of the barrel and breech, to differentiate it from other "12-pounder" guns.

QF 12-pounder 18 cwt naval gunW

QF 15-pounder gunW
QF 15-pounder gun

The Ordnance QF 15-pounder gun, commonly referred to as the Ehrhardt, was a modern German field gun purchased by Britain in 1900 as a stopgap measure to upgrade its field artillery to modern QF standards, while it developed its own alternative. This was precipitated by the experience of the British Army in South Africa during the Boer War, where its standard field gun, the BL 15-pounder, was out-performed by modern French and German field guns deployed by the Boers. It bore no relation to the BL 15-pounder or BLC 15-pounder, two other guns in British service at the time, other than a common shell.
