Construction: The bodies are of single-piece forged, machined construction, with pointed noses, parallel sides, and slight boat tailing. The base plate is of the male type. Suspension in the 1,600-pound A.P. Bomb Mk 1 design was by means of lugs welded to bands, the bands being postioned by grooves on the external bomb surface. The newer designs, AN-Mk 1 and Mk 33, are suspended by fittings which screw into holes drilled into the bomb case and secured by bolts. The normal box-type tail assembly is used on these bombs.

Filling: The main filling of these bombs is pressed Explosive "D" or cast TNT. The tail fuze pocket requires the use of the granular TNT Auxiliary Booster Mk 1.

Remarks: The later 1,600-pound A.P. Bombs Mk 1 Type were grooved to position the suspension band. Older bombs had a stud which fitted into a hole in the bomb body.
