18-in Mark VIII Torpedo (UK)
From The Dreadnought Project
The 18-in R.N.T.F. Mark VIII Torpedo was a British torpedo developed at the Royal Navy Torpedo Factory in 1912, specifically designed for use in submarines.[1]
Development and History
To make a torpedo for submarines, the design called for a "very heavy explosive charge", obtained at the expense of range. Two were built for trial in 1913.[2]
The test torpedoes' warheads were 320 pounds of T.N.T., allowing operation at stamped speeds of 41 knots to 1,500 yards and 29 knots to 3,500 yards when charged to 1,600 psi. They had Service depth gear with double hydrostatic valves and an engine like the Mark VII's, but with lightened pistons and connecting rods.[3]
