Type C Depth Charge (UK)
Adapted from Aeroplane bomb R.L. Pattern 22262, it was streamlined like a small bomb and had 25 pounds of T.N.T. or Amatol initiated by 0.75 pounds of Tetryl, yielding a 10 foot danger radius.
The Type C was triggered by a float at either 40 or 80 feet, and the Type C* was hydrostatically triggered at 50 feet. With an overall weight of just 90 pounds, these were among the lightest depth charges. They sank at 10 feet per second and were about to be issued to small craft in October 1915. By early December, the Type C was being issued and the Type C* was soon to be ordered.
