Body Construction: The bomb body consists of a pot-shaped, cast-steel cylinder which is open at the top. A steel neck ring, having internal threads to receive the adap-ter, is welded to the open end of the body. The parachute tray is secured to the adap-ter. Extending through the adapter is the fuze, which is enclosed by a paper tube 2-in. in diameter, extending through the bomb body. |
Parachute: The parachute is 12 in. in diameter and is encased in a cylindrical steel tray having a diameter slightly less than the maximum diameter of the bomb body. A safety pin extends through the parachute container, and is secured by a spring clip. |
Explosive Components: Main Filling – 1¾ lb. (approx.) of TNT, or RDX/TNT 60/40; 1½ lb. (approx.) of Amatol 50/50 or 60/40, or Pentolite/D1. (When filled with explosive other than TNT, a ¼-in. topping of TNT is added.) |
Remarks: The Mk I Bomb had a smaller filling hole than the Mk II. The Mk I was never filled or adopted for service use. |
