Scroll Prev Top Next More


Adapter-booster M115A1 provides a tail fuze seat for some general purpose bombs. The adapter-booster requires a lock pin to prevent its removal after an anti withdrawal fuze is inserted in the bomb.

This adapter booster has an inner sleeve with an inside diameter of 1.5 inches to accomodate Army designed fuzes. If the sleeve is removed, it will accomodate Navy designed fuzes, which have an inner diameter of 2.0 inches. The cavity provided by the adapter booster is 2.68 inches deep.

The M115A1 differs from the earlier model M115 in its provision for the locking pin.
