History
The Vickers P was a cannon designed due to the lacking ability of the 40 mm armed Hurricane IID in destroying Tiger 1 tanks in North Africa. The air staff put out an issue in 1942 for a 47 mm airborne anti-tank gun which would fire a 4 lb 9oz (2.07 kg) solid AP shot at 2,650 fps (808 m/s) with a rate of fire no less than 60 rounds a minute.
Vickers was contracted to make the rounds, case piece was 326 mm long, the rim diameter at 59.7 mm with the body diameter at 52.3 mm, the shot was typical of most other British rounds of the time, solid AP shot with no HE filler, overall with the shot fitted the round was 474 mm long.
The gun itself was in contest by three firms of the time, Vickers, Rolls-Royce and the war office design department, the project was known as the "class P gun" as such the competing designs were known as PV (Vickers) PR (Rolls-Royce) PC (for the Chief superintendent of armament design in the war office).
Complete information about the three projects does not appear to have survived. The PR gun was designed with two different barrel lengths, a 70-calibre barrel (with which the muzzle velocity was calculated to be 2,675 fps or 815 m/s) which was about 4.3 m long overall, and a 52-calibre version. The gun was belt-fed and used a long-recoil design; the weapon recoiled 66 cm on firing, generating a peak recoil of just over 2,000 kg. The PC gun weighed 250-270 kg and recoiled only 30 cm, thereby generating a stronger peak recoil of 3,560 kg. This was magazine fed with two alternative designs; a 30-round flat box lying across the gun's body, and a 34-36 round drum wrapped around the rear of the gun. Overall length was 4.5-4.7 m respectively. No information is recorded about the PV gun, but it is believed to be a development of the earlier 40 mm Vickers S.
The PV and PC guns were made but were not ready for firing until close to the end of the war. The PR gun was cancelled before completion during the war when Rolls-Royce was directed to cease work on guns. None of the Class P guns proceeded beyond the prototype stage. However a Tempest V was fitted with two of the Vickers guns in under-wing pods just after the war, but no records have been found concerning this installation.
