The British Type A Depth Charge was an early, small antisubmarine weapon adapted from the "Vernon boom" described in the Annual Report of the Torpedo School, 1915.[2]
Particulars
The total weight of the weapon was 210 pounds, only about 1⁄7th of this weight being explosive: 32.5 pounds of gun cotton initiated by a G.C. primer of 2.25 pounds.
Explosion was triggered mechanically by a float and wire system at a depth of 40 feet. Vernon calculated that this gave the weapon a 10 foot danger radius. It was the first British depth charge to be used and was in general use by small craft in October 1915.
The Type B was a minor refinement of the design, offering an 80 foot detonation depth option and a lower overall weight, and the Type E greatly increased the proportion of explosive comprising the overall weight.
