Ordnance Pamphlet 1507, OP-1507, published 20 April, 1945, contains a summary of the more important items of Japanese underwater ordnance, such as mines, depth charges and torpedoes. It is designed to aid in identifying the items, to give their tactical characteristics and to outline precautions to be taken, as required.  Numerous drawings are included.

This publication is not intended to give instruction regarding the disposal of such ordnance. These operations remain the duty of specially trained personnel.
