REMARKS:

The AN-M30A1 differs from the AN-M30 in these respects:

(a) The AN-M30A1 incorporates two pins fitted into the base plate which extend into the main filling and prevent removal of the base plate.

(b) The AN-M30A1 uses the M102A1 adapter booster, which has a 3/8" hole, mating with a groove in the internal threads of the base plate. A locking pin, ship-ped with anti-withdrawal fuzes only, fits through the hole and into the groove and prevents extraction of the adapter booster. The pin is held in place by the fuze body.

To overcomes the erractic flight of AN-M30 and AN-M30A1 bombs when dropped from high altitudes by very heavy bombers, the tail assembly of the M81 260 lb. fragmentation bomb replaces the customary tail unit, which is 2 inches shorter, for such missions.

Use of the M22 cluster adapter permits single suspension for four AN-M30 or AN-M30A1 bombs.

When anti-ricochet action is disered, the M16 anti-ricochet device is employed, consist-ing of the M7 parachute, M202 fuze adapter, and M151 tail fuze.

For Construction of Body, Suspension, Color & Markings, Type of Filling, and Tail Construction see Introduction, page 37.

In order to alleviate a shortage of 100 lb. M38A2 practice bomb, described on page 324, a concrete practice bomb, the M85, having the same weight, contour, and center of gravity as the AN-M30A1 is being used.
