Egerton Depth Charge (UK)
The Egerton Depth Charge was an unusual weapon comprising two identical charges with a electrical wire between them. It is described very briefly in the Annual Report of the Torpedo School, 1915.
Adapted from a modified sweep, Egerton charges were in equal pairs, separated by 120 feet of electrical triggering wire. Each of the two charges was 75 pounds of T.N.T. set off by 2.25 pounds gun cotton primer, giving each an estimated 25 foot danger radius and the total weight for the assembly of 200 pounds. These were in general use by destroyers and other vessels in early October 1915, but were to be replaced in use by the Type D depth charge as supplied increased.
There is not enough detail to determine how this device was used.
