Sunken Pillboxes Guarded Jap Coast (Mar, 1947)

I find this rather hard to believe. It doesn’t seem practical, nor does it seem that 40 people would be neccessary to man 3 torpedo tubes.

Sunken Pillboxes Guarded Jap Coast
Japan’s anti-invasion line went out under water at Tokyo Bay. Pillboxes were built into the hulls of sunken ships and equipped with three torpedo tubes and a sound detector. Each pillbox held 40 to 50
men who were relieved every 10 days. Food was canned; oxygen, bottled.

    I agree. Only 3 torpedoes and 40-50 staff?
    Found this about the Japanese defenses which seems specific enough that they would have mentioned this one had it existed:
    “The demolition teams started to neutralize Japanese defenses, August 28,1945, in Tokyo Bay and on mainland Japan, prior to the formal surrender aboard the USS Missouri, September 2, 1945. After the initial “demilitarization” of ships in Tokyo Bay was completed, IE: (destroying ammunition, dismantling guns and throwing the breeches overboard), the teams moved inland. There they blew up fleets of suicide boats moored all along the coast, exploded torpedoes, disabled or destroyed two man “suicide” submarines. In caves that honeycomb the coastline, the big coastal defense guns were blown up.

    “Weapons guarding the Japanese homeland were insidiously camouflaged.” Gun emplacements were buried in craggy hillsides. Their ammunition supplies moved through a series of underground tunnels on tiny railroads they could have never are seen by invaders from the sea or air. Huge caves had been hollowed out in the hills along the coast. These were crammed with heavy armaments, torpedoes, small suicide submarines, mines and all manners of explosive devices.”

    If it’s in Popular Science it HAS to be true…

    @ Tim: I think you mean “Popular Science Fiction”. At least, that’s what I’ve always called it. 😉
