| Description: |
|---|
| This bomb consists of a cylindrical metal container with a hemispherical nose and tail piece welded at either end. Buster containers are located at each end of the bomb and, in the tail, to one side of the buster tube is a filling hole closed with a threaded plug. A tail locating ring is welded around the after portion of the bomb body. Although provision is made in the bomb for alternate nose or tail fusing, the nose pocket is always closed with a plug, and only the tail pocket is employed. |
| Use: |
|---|
| There are at present in service use only four smoke bombs, exclusive of those bombs containing smoke spotting charges. These are the 4-, 1O0-, 120-, and 500-lb. smoke bombs. The bombs are used to lay smoke screens to conceal troop movements. |
| Functioning: |
|---|
| The Tail No. SI Mk I consists of a sheet-metal tail cone to which are riveted four vanes supported by a cylindrical metal strut. The tail is attached to the bomb by four spring clips, which engage the tail locating ring on the after end of the bomb body. Inside the tail cone, supporting the lower end of the reach rod, is located a diaphragm with four large holes to allow air passage. |
