    Evening All. Just watching Das Boot here and thinking .....

    How does that deck gun work? o_O

    What was it with them? Why did the sea water not wreck them?

    When you look at a Submarine gun 'in the flesh' (eg: at HMS Alliance), it becomes more obvious that the entire thing is made of 'shinier' :unsure: high-quality materials, no doubt carefully selected and waterproofed to resist the briny deep. They did have Tompions but I believe they could function OK without them, just more likely to get debris down the tube.

    You can see here how little concretion (?) has formed on this one after 80+ years submerged:

    It's fascinated me before, but I suppose Guns are essentially quite straigtforward things... If they could make the boat itself go under the water then the gun's got to be a pretty 'easy' part of the whole?

    :huh: That's a thought provoking statement, Poopers. I think I'll hit the surf now. And try not to dwell on that one! :lol:

    Still got Das Boot amongst my few, yet to be watched, DVD's. Saving The Best till last! The wait's still killing me though .....

    Steve , go watch it right away - an outstanding movie - some gaffs in it ( all movies have them) , but an excellent film which should not be missed.

    Deck guns - used a shorter 88mm shell , gun crews were well trained , those on merchant ships had little chance against them.

    Below Teddy Suhren helps make an adjustment on U564's deck gun.

    The optical sight is quite a nice toy but its a case of "an arm and a leg" if one comes up for sale.

    x5 magnification on the sight - this illustration from Hans Seegers "Grey Book" on Military optics , it took two men to use this sight properly.
    Trained gunners could out shoot any merchant crew with ease.

    There is an instance of a U-Boat surfcacing to fire on an oil refinnery in the Caribbean , but the crew failed to remove the waterproof tompion and the round exploded in the barrel.

    Type VII U-boat deck gun. The gun had identical laying and aiming controls on either side so that ammunition could be passed directly to the gun from the hatch no matter its orientation without obstructing the gunners view. But the gun only had a single set of sighting instruments which had to be switched from side to side if the gunner changed position. Each position also had padded chest braces to help the gunners keep steady aim in rough seas. The water tight muzzle plug (tompion) is in place, attached to the gun by a line seen wound around the barrel.

    Top add to Peter's post , the attached comes from Robert Stern's "Type VII U-Boats" - ( Arms and Armour Press).

    Crews would be expected to ( whenever possible) to recover and return casings for recycling.
    Rounds were kept in watertight transit containers , (fluted metal jacket) with a sealed top , the round was shorter in length than the standard 88mm round.
