BODY CONSTRUCTION: |
Streamlined one piece cast steel, with nose end open to take ex-ploder container; rear and reduced to form a spigot for taking pa-rachut attachment. Spigot is tapped and threaded to receive securing stud of parachute attachment. Exploder container is cemented and locked in position. The No. 873 nose fuze is locked in position by a multi-tab washer. |
TAIL CONSTRUCTION: |
No tail is used with this bomb, which is aspecially designed to be used only in the No. 17 Mk II cluster. It has a short parachute attachment, secured to body spigot by a threaded stud. The parachute tray houses an 8" diameter fabric parachute with six pairs of rigging lines, each pair teminating in a whipped eye. These eyes pass through holes in the tray and are threaded on to a metal circlip which is secured on the under-side of the tray. A lid over the parachute in the tray is held in position by the fuze of the bomb behind it. When the cluster opens, the airslip displace the lid, which pulls the chute free of the tray. |
SUSPENSION: |
Has no suspension lugs, being used only the No. 17 Mk II cluster. |
EXPLOSIVE COMPONENTS: |
Exploders: | Two T.N.T. and two perforated C.E. pellets. |
Filling: |
3.1 lb. (approx.) of T.N.T. |
REMARKS: |
The bomb is issued only in clustered form, and when clustered, the fuze has no safe-ty pin fitted. Hence, care should be exercised in dealing with any individual bombs which might break loose from a cluster in handling. |
