Within the context of a recent blog entry this extract from Strategy Page most apropos.
"Bouvet, Irresistible and Ocean having hit and been sunk by naval sea mines!!"
NOT so much that the sea mine is effective but that it is so cost-effective.
"Murphy's Law: The Super Weapon Everyone Wants To Ignore"
"Naval mines achieved several striking successes during World War II. In the Pacific naval mines proved more destructive to the Japanese war effort than the atom bombs. During a 10 week period between April and August 1945, 12,000 mines were delivered to the Japanese coast by American bombers. These destroyed 1,250,000 tons of Japanese shipping (670 ships hit, 431 destroyed). That's 18 mines for each ship hit. The Americans had air superiority, so losses during these 1,500 missions amounted to only 15 planes, most of them accidents. Had these missions been flown against opposition, losses would have been between 30 and 60 aircraft, plus similar losses to their fighter escorts. Either way it was a stunning success for naval mines"
This is an actual sea mine as being dropped from a B-29 during Operation Starvation?
American submarines primarily waging naval warfare in that area of the Pacific, attack on Japanese EXTERNAL lines of communcation.
Those B-29 bomber dropping sea mines in that area of Japanese home waters attack on INTERNAL lines of communication! THIS WAS OPERATION STARVATION! Deny the Japanese the ability to move large quantities of grain within the confines of the home islands.IF THE WAR HAD CONTINUED MUCH LONGER ABOUT 10 MILLION JAPANESE IN GRAVE DANGER OF MALNUTRITION, HUNGER, SEVERELY DEBILITATED OR SUFFERING DEATH FROM A LACK OF FOOD!!
