New (to me) historical gun

Hmmmm, maybe Germany should be buying these http://www.navweaps.com/Weapons/WNGER_21-52_gerat36.htm for coast guns?

[Hadn't heard of this gun before I looked at the site a week or so ago. Hmmmm......

Firing rate <1RPM....

is somewhat less than ideal.

Although the tsunami-scale shell spashes might swamp destroyers and smaller ships.

Agreed, the ROF isn't great, but for the size it's not too terrible. I'm a little surprised it's rated as low as it is, actually, considering the rating on some other guns of nearly the same size (though the 4850 pound shell and 1763 pound propellant charge (plus the 346 pound cartridge) probably has something to do with it). On land, I'd expect it to be around 1 round per minute, perhaps up to 1.2 rounds per minute.

Good grief: 485 pound bursting charge for the nose-fuzed HE??? Over 100 pounds for the APC round? ~350 tons per gun. And a range of over 50,000 yards (before fancy projectiles).

Hmmmnn......

Hmmm. Mount 6 of these in BSG mountings at Wangerooge, Cuxhaven, the southern islands off Schleswig-Holstein, at Fehmam (near Kiel), and at Konigsberg, along with lighter weapons. Got to test them first, of course, and production would take a while, but still.....

Wangeroog is really just a sandbank. You don't want to build a gun emplacement there. Most places on that coastline are poor choices as the water isn't really deep enough for ships to come within range.

Wangerooge may be a sandbank, but that's not uncommon for this sort of service. It was also the site of a 6-gun 12" battery during WWII (see http://www.navweaps.com/Weapons/WNGER_12-50_skc12.htm).
The water's not ideal in this area, but then the idea is not so much to actually sink ships as to keep hostiles away from my bases at Cuxhaven, Bremerhaven, Wilhelmshaven, Hamburg, Kiel, Konigsburg, etc.

Looking over things, the 406mm Adolph is probably a better choice in single turret with the 600kg long-range shell.

Possibly true. Though, in WW, I could use the standard 900 kg 38cm shells in this gun with sabots....

Chances of hitting anything go down considerably though. Peenemunde Pfeilgeschoss style saboted rounds or a mor common cup type? Could always just fit a smoothbore extension to the gun.

True, but then, at the ranges the special shells would be used, hits would be mostly luck anyway. Not a Pfeilgeschoss, standard cup-style.

Its looking about 1.5 MJ shock just to fire this MONSTER. Are you sure any 1930 steels can handle the shock?

Shouldn't be a problem, considering the 80cm gun Heavy Gustav had no problems and the prototype for that weapon was on the test range in 1939.

hmmm a couple of these on Heligoland might be quite fun.

Just ran it in big gun for fun, at 30 degrees elevation this thing would supposedly penertrate 15+inches of belt of 12+inches of deck!
