Construction: The bomb is of three-piece sheet-steel construction, with a hemisphe-rical nose piece and a conical tail cone welded to a tubular body. The bomb has two sus-pension lugs on bands or a single lug on a band near the center of gravity. The tail as-sembly consists of four sheet-steel vanes welded to tail cone, which, in turn, is welded to the body.

Color: The bomb is painted grey over all, with a bright red disc, four inches in diame-ter, in the middle of the body.

Remarks: This bomb is similar to the 100-pound Incendiary Bomb AN-M47A2, excpet that it is equipped with a filler cap. Both bombs are prone to leak and should be examined frequently.

There is also a 100-pound Incendiary Bomb Mk 1, which is almost identical to the old Army M47, both of which are obsolete.
