The 14-in R.L. Mark IV Torpedo was an early British torpedo manufactured by the Royal Laboratory.
A Royal Navy order of 50 of the new model was made in the 1883-84 fiscal year, with 30 the following year.[1]
In 1885, the British diversified their manufacture base by giving Messrs. Greenwood and Batley of Leeds a contract to build 100 units at a rate of 20 per year.[2]
Also in 1885, however, the Royal Laboratory at Woolwich was asked to move on to the Mark V model and received an order to make 200 of them.[3]
52 Mark IV torpedoes were found to average 23.69 knots (ranging from 22 to 25.5 knots) over 600 yards with a 70 pound charge of dry gun-cotton in water temperatures between 50 and 70 degrees.[4]
