Description
This ammunition is designed for harbor defense purposes and will probably not be used afloat.
The round consists of one Depth Charge Mk XI, without tail, fitted with 12 Propelling Tails, Rocket, No. 5 Mk II. These motors are mounted in a cylindrical shell encircling the depth charge. The shell measures about 21 in. long by 17 in. external diameter, and weighs about 100 lb. The complete round assembled weighs about 375 lb.
The round is fired electrically from a single mount, trough type launcher. The electrical circuit is selectively arranged so that from 4 to 12 motors may be fired, giving ranges varying from 65 to 500 yd. in 50 yd. increments. Large fins may be fitted to the round, but at ranges under 300 yd. fins are usually omitted from the assembly.
