Military Wednesday - Naval Mines
Wednesday, Aug 10 2011 by kjfitz
A naval mine is a self-contained explosive device placed in water to destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel. Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbor; or defensively—to protect friendly vessels and create "safe" zones.
