Grasshopper Cannon
Grasshopper was the nickname for a cannon used by the British in the late 18th century as a light battalion gun to support infantry. It was designed for service in rough terrain such as the frontiers of British North America. Its barrel was made of bronze instead of iron. Bronze is less brittle than cast iron, and so the barrel could be made thinner and lighter than that of an iron gun. If a bronze gun developed a defect it would rupture; an iron gun with a flaw would shatter, at great cost to its own crew. It fired a ball (or same weight of canister shot). Using the conventional bracket or split trail, the gun could be moved by its own crew using drag ropes and wooden shafts much like a handcart. Two straight shafts were placed on each side of the cheek pieces facing forward, and two angled ones at the trail. The appearance of the shafts when fixed in place led to the nickname of ''Grasshopper''. Famous battles with grasshopper cannon *Cowpens in the American Revolution *Guilf ...

QF 3-pounder Hotchkiss
The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts. Operational history French service The French Navy used two versions of the Hotchkiss 3-pounder: the short-barreled M1885 and the long-barreled M1902, which had a larger muzzle velocity than its predecessor. The French L/40 M1885 and the British QF 3-pounder were largely the same gun. Like the British who paired their 3-pounders with the larger QF 6-poun ...

QF 3 Pounder Nordenfelt
The QF 3-pounder Nordenfelt was a light 47 mm quick-firing naval gun and coast defence gun of the late 19th century used by many countries. United Kingdom The United Kingdom only deployed this gun for coast defence, and soon discarded it in favour of the similar QF 3-pounder Hotchkiss gun for both coast defence and naval use. Ammunition Ammunition was in "fixed rounds" : the projectile and brass cartridge case were loaded as a single unit. The gun used the same ammunition as the similar QF 3-pounder Hotchkiss, with either Nordenfelt or Hotchkiss fuzes. When introduced in the 1880s the propellant used was gunpowder, in British service Cordite Mark I was used as propellant from the mid-1890s onwards.

Ordnance QF 3-pounder Vickers
The Ordnance QF 3-pounder Vickers (47 mm / L50) was a British artillery piece first tested in Britain in 1903. It was used on Royal Navy warships. It was more powerful than and unrelated to the older QF 3-pounder Hotchkiss, with a propellant charge approximately twice as large, but it initially fired the same Lyddite and steel shells as the Hotchkiss.Treatise on ammunition 10th Edition 1915. War Office, UK. Page 404 Development Starting in 1904, the Royal Navy bought over 154 of these for use as anti-torpedo boat weapons on capital ships and to arm smaller ships. British production of these guns started in 1905 at Vickers and by the time production stopped in 1936 a total of 600 weapons had been made. Royal Navy use By 1911 about 193 guns of this type were in service, and they became standard equipment in the Royal Navy until 1915. In that year, service during the First World War proved these weapons to be ineffective and they were quickly removed from most of the la ...

OQF 3-pounder Gun
The Ordnance QF 3 pounder 2 cwt gun was a 47 mm British tank gun based on the Ordnance QF 3 pounder Vickers naval gun, mounted on Vickers-built tanks in the 1920s and 1930s. The gun was produced in 31 calibre (59 inch) and 40 calibre (74 inch) versions. The weapon only fired a solid shot, and was stated in the requirements of the A6 series of Vickers Medium tanks to have the ability to penetrate the armour of contemporary hostile tanks at a range of 1000 yards. The Vickers Medium Mark I was equipped with the Ordnance Quick Firing 2cwt Mark I version of the weapon, whilst from the Vickers Medium Mark II the Mark II version of the 3-pounder was utilized. Even though other European countries still fielded similar weapons (e. g., Cannone da 47/32) at the start of the Second World War (and quite a few years into it), due to its comparatively low muzzle velocity the 3-pounder was considered obsolete by the war start by the British, with the Ordnance QF 2-pounder replacing it as the ...
