High Quality Content by WIKIPEDIA articles! The Ordnance QF 3 pounder Vickers was a British artillery piece first tested in Britain in 1910. 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. Starting in 1914, the Royal Navy bought over 150 of these for use as anti-torpedo boat weapons on capital ships and to arm light craft. British production of these guns started in 1910 at Vickers and by the time production stopped in 1936 a total of 600 weapons had been made.
