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.[2]
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.[3]
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.[4]
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.[5]
In 1893, the Mark IV (but not the Mark IV*) were to be replaced when newer units became available.[6]
An extensive report on torpedoes being adjusted at the test ranges shows the Mark IV is not in use in 1896.[7]
In 1919, it was approved to break up all 14-in torpedoes except for a reserve of fifty each of 14-in Mark X* torpedo and 14-in Mark XI torpedo.[8]
Mark IV
The particulars are detailed in the Annual Report of the Torpedo School, 1883.[9]
Mark IV*
An extensive report on torpedoes being adjusted at the test ranges shows the Mark IV* is still in use in 1896, as some were run at Horsea:[10]
- one R.L. torpedo averaged 22.33 knots at 600 yards in 52 degree water.
- two R.L. torpedoes brought in for repair averaged 20.78 knots at 600 yards in 56 degree water.
- one G&B torpedo averaged 20.69 knots at 600 yards in 68 degree water.
- four G&B torpedoes brought in for repair averaged 20.85 knots at 600 yards in 43.25 degree water.
