Battleship Tirpitz 2022. 78 years after her sinking, her high quality armour plating is used in construction work all over Norway.

  1. You know that there are companies trying to scrape as much metal from sunken ships from the seafloor because they are not contaminated with radioactive isotopes??? They need them for high quality medical products and nuclear sensing…
    Pls tell me that this is not used for a fucking construction work.

  2. I’m skeptical, without more information, that that sheet of metal in the lowest image is armor plating. That’s a very thin sheet of metal.

    Yeah. I call shennanigans. That sheet *might* be one inch at most.

    EDIT2: Here’s a British company that sells steel road plates of the sort shown in the picture:

    >Our Steel Road Plates are manufactured from mild steel and we supply them in a range of steel gauges in order to best suit your needs and application. We recommend using 13mm thick Plates for pedestrian use and the thicker 19mm Plates for allowing vehicles to pass over them.

    That looks to me like it could be a 19mm plate, a bit under an inch.

    EDIT3: To try to provide some context, a .50 caliber heavy machine gun round can penetrate on the order of 20mm of armor at relatively-close range. That metal plate there, even if it’s hardened armor and not mild steel, would probably still permit penetration of such a bullet. That isn’t going to be doing much if you’re talking about the kind of munitions that battleships are going to be hurling at each other.

  3. We had some spare parts of Bismarck’s armour belt (retrieved post war from the shipyard where she was built) in use to shield some instruments in our department of nuclear physics. Post-1945 steels are all slightly contaminated due to atmospheric atom bomb testing, so these old steels are still sought after.
