    Wow

    Again Rusty hits a grand slam THANK you
    thats exactly what I was wondering
    It would be very difficult If near impossible
    to get a star wars shot down the death star hole (stacks)

    Sir, you and Janusz Skulski should get together and with your
    knowledge and pictures and JS illustrative expertise could make
    one HELLUVA Iowa class book, the be all end all book on them...... :)

    Each uptake and main exhaust are jogged over (deliberately miss-aligned) between the 2nd deck and main deck.

    The main deck "grill" is about 4" thick (in a 1 1/2" thick deck) and the 2nd deck grill is about 7" thick (in a 6" thick deck).

    The largest holes in any of the grills are 5 15/16" in diameter. Why such an odd selection? So a 6" shell from a light cruiser will not go through.

    Photo is of an armored grill in the main deck of the Iowa.

      Are you sure you're discussing uptakes and not intakes?

      Intakes feed the forced draft blowers which feed the boilers.
      Uptakes basically take the flue gasses from the top of the boilers, through the economizers and eventually through the funnels.

        Doesn't make much difference as they both have to jog through the decks. However the intakes are generally the most vulnerable as they do not have to be double bulkheaded to keep the exhaust heat from toasting up the surrounding compartments.
        Able to leap tall tales in a single groan.
