US Bomb, 1000 lb AP, AN-Mk 33 Mod 1, 2, 3




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 positioned 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.

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.

The later 1,600-pound AP 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.

There are no physical differences among Mods 1, 2, and 3. The mod number is used only to identify the manufacturer.
