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.[1]
