Type A, B and E Depth Charges[1]
The British Type E Depth Charge was a small antisubmarine weapon adapted from the "Vernon boom" described in the Annual Report of the Torpedo School, 1915.[2]
Particulars
The Type E was similar to the Type A and Type B depth charges, but employed a much larger, cylindrical hybrid charge of 100 pounds T.N.T. or Amatol and 16.25 pounds guncotton, initiated by 2.25 pounds of gun cotton, yielding a danger radius of 35 feet rather than just 10. Its overall weight of 220 pounds was only as heavy as the Type A, allowing it to sink at 5 feet per second before being triggered by a float and wire at 40 or 80 feet.
By the 1st October 1915, it was to be issued to motor launches, whalers, sloops and patrol craft. It was actively being issued by 1 December.
