18-in Weymouth Mark I Torpedo
The 18-in Weymouth Mark I Torpedo was a heater torpedo built by Whitehead and ordered in small quantity in 1908-09.[3]
Development and History
In 1908-09, twenty S.L. units were ordered.[4]
In 1909, these twenty were returned to Whitehead for "radical alterations in the engines", as they had been found not to be strong enough.[5] By 1910, the re-engined weapons were passing their range tests nicely.[6]
Mark I
The warhead contained 161.75 pounds dry guncotton which weighed 198 pounds with 22.5 parts moisture.[7]
Its overall length including 4.5-in long pistol was 17 feet, 6 inches (see Plate).[8]
Mark I*
34 of these were ordered from Whitehead in 1913-14, and by November 1913, 9 had been delivered.[10] The details are contained in Torpedo Orders 48 and 66 of July and September, 1913.Template:ARTS19113
