The Ordnance quick-firing 6-pounder 7 cwt, [note 1] or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army (as the 57 mm gun M1). It was also used as the main armament for a number of armoured fighting vehicles.
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light 57 mm naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. Many variants were produced, often under license, which ranged in length from 40 to 58 calibres, with 40 ...
6-pounder gun or 6-pdr, usually denotes a 57-millimetre (2.2 in) gun firing a projectile weighing approximately 6 pounds (2.7 kg). Guns of this type include: QF 6 pounder Hotchkiss , a 57 mm naval gun of the 1880s; a similar weapon was designed by Driggs-Schroeder for the US Navy
The BL 6-inch gun Marks II, III, IV and VI [note 1] were the second and subsequent generations of British 6-inch rifled breechloading naval guns, designed by the Royal Gun Factory in the 1880s following the first 6-inch breechloader, the relatively unsuccessful BL 6-inch 80-pounder gun designed by Elswick Ordnance.
In 1940 as part of the British anti-invasion preparations, a large number of pillboxes were built to a design, known as Type 28 or FW3/28, intended for the modern 2-pounder anti-tank gun. However, as these were in desperately short supply, 6-pounder Hotchkiss guns firing solid shot were used instead.
The spherical case shot weighed 5.7 lb (2.6 kg) and released 41 musket balls when it burst. The canister round weighed 7.32 lb (3.3 kg) and contained 27 iron balls. [ 17 ] At 5° elevation, the gun could hurl the round shot a distance of 1,523 yd (1,392.6 m) with the standard firing charge of 1.25 lb (0.6 kg).
The 14.9 lb (6.76 kg) HE shell fired at 2,050 ft/s (625 m/s) was found to be the best available and superior to that of the 6-pounder, M7 3 in and 17-pounder, all chiefly anti-tank guns. Against armour, its AP shell was the worst, penetrating only 68 mm of RHA at 500 yards (460 m) and a 30-degree angle of attack, whereas the AP shells of the ...
