The 25-pounder cannon (Royal Ordnance QF 25-pounder, or 25-pdr for short) is a British howitzer developed after World War I, which was introduced to the British Army in the late 1930s. It was intended to replace 84mm (18-pounder) cannons and 114mm howitzers. (4.5 inches), used on the fronts of World War I It is considered one of the best guns ever built - it remained in British service until the end of the 1950s, and its small amounts were used for training purposes until 1967. The Haubicoarmata QF-25 was one of the first in the British Army to use a semi-combined missile. This type of ammunition combines the advantages of composite ammunition (high rate of fire) and collapsible ammunition (the possibility of changing the mass of the propelling charge). Additionally, a special charge was developed to increase the maximum range of the gun to more than 12 km, which, however, necessitated the addition of a muzzle brake. The QF-25 fired a wide range of ammunition: from high-explosive, smoke, anti-tank shells to illuminating and incendiary shells. The QF-25 was used on all fronts of the Second World War, and each British infantry division had 3 artillery regiments equipped with 72 guns of this type. The Morris C8 artillery tractor was used very often for transport. Several gun variants were created, the most important of which are: Mark I, Mark II and Mark III AND Short, Mark I, built under license in Australia, designed specifically for activities in the jungle. Technical data: range: 12,250m, caliber: 87.2mm, combat weight: 1288kg, rate of fire: 4 shots / min
