Adapter booster M102A1 provides a tail fuze seat for certain GP and SAP bombs. It requires an adapter booster lock pin to prevent its removal after an antiwithdrawal fuze is inserted in the bomb. The required lock pin and a lock pin instruction card are wired to the fuze. The M102A1 has an inner diameter of 1.5 inches and its cavity is 2.86 inches deep.
The M102A1 differs from the earlier model of M102 in its provision for locking pins.
