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 1910, these were returned to Whitehead for alterations to engines, and were passing their range tests nicely. It seems that a delayed delivery was to commence.Template:ARTS191p. v
