Folks,
We have added a new manual up on the HNSA web site. Mine Disposal Handbook, 1945, was created by the U.S. Navy Bomb Disposal School near the end of WW II. It covers all forms of underwater ordnance, not just mines. The Japanese and US sections are very good cross sections of the war's underwater ordnance.
