| A.S. bombs, ranging from 100 to 600 lb. are at present in service use. They are thin-walled bombs, having a high charge/weight ratio for maximum blast effect on, or under, water. Air¬craft depth charges are used by the British as alternatives for these bombs. |

A reach rod, with arming vanes attached to after end, extends through the cone and engages the arming fork of the tail pistol. The tails of the Bombs Mk IIII consist of a cylindrical strut attached by four fins to a dome-shaped tail cone, and secured to the bomb by a central bolt. |
