Description

The AN-M30A1 (100 lb) is an American general purpose high explosive (HE) bomb.

The AN-M30A1 is an air-dropped bomb which utilises a combination of blast damage, penetration and fragmentation during its explosive effect. Typically the general purpose bombs are used when targeting either enemy troops, vehicles and buildings.

General purpose bombs are aerodynamic in shape and have stabilising fins to enable accurate drop locations when sighted, targeted and released by a bombardier. The aerodynamic effect also benefits aircraft which carry the bombs on external payload pylons.

General info

This bomb was manufactured in one of three ways, either cast or spun as one piece, cast as two pieces and welded or cast as three pieces and welded. The nose contained a threaded opening which is closed by the fuze-seat liner and the male plug at the tail is closed by an explosive adapter booster.

The AN-M30A1 is outfitted with two suspension lugs which are directly welded to the bomb casing 14 inches apart. A single suspension lug is welded to the opposite side of the bomb at the centre of gravity which can be utilised to suspend from British aircraft.

This version of the AN-M30 bomb, the A1 version indicates that a modification which locks the base plate to the central filling via two steel pins, preventing the removal of the base plate once the bomb is filled with its explosive material. Once the adapter booster is inserted, a pin is inserted which prevents its withdrawal.

The tail section of the AN-M30A1 bomb is a cast-steel sleeve known as a box-type tail. The Sleeve is manufactured of a cast-steel sleeve with four sheet-steel fins held into place with a locking nut. Each fin is held by a fin-strut which once in place are welded together to make one assembly. Different tail fins were utilised when the low-altitude bombing took place compared to higher altitude bombing.

The AN-M30A1 was painted with a standard colour scheme since 11 March 1942; the body was painted olive drab while yellow stripes were added to indicate the bomb was a HE. To differentiate what type of filler was used, a one-inch yellow band at the nose and tail along with a 1/4 inch dotted band at the centre of gravity of the bomb which indicated it was filled with 50/50 Amatol or TNT fillers. A second yellow band was added to the nose and tail of the bomb if it was filled with Composition"B" which required special handling due to its sensitivity. Standard marking on the bomb body in black paint included type, weight, name of bomb, type of filling, lot number, date and place of filling along with the inspector's initials. Indestructible markings of this information were also stamped into the casing before filling with explosives.
