KM Graf Von Roon (BC-1938)
Back to Germanic States Navy page:
There was a lot of design work undertaken between the real life Deutschland
Class Panzerschiff and the Scharnhorst Class Battleships. In the Germanic States
realm, the Panzerschiff feature 6 x 13.8" in two triple turrets and the
Scharnhorst type may go to 9 x 13.8" depending on what I do with the French
answer to the Panzerschiff. It will probably get worse before it gets better,
and as I dream up more and more different types of vessels that could fit into
these realms. Anyway to the Roons.
With the first of the Deutschland class at sea and two more building, the design
for ships four to six was to be enlarged to make them more capable, with better
staying power. One of the original designs was just an enlarged Admiral Scheer
which while better still had many of the same faults.
Length CWL: 207,00m
Length 209,05m
Beam: 25m
Draft: 7,7m
Displacement: 18.000 - 19.000 tons
Propulsion: Turbines ca. 70,000 shp - 2 shafts
Speed: ca 26 knots
Armament:
6 x 28cm (2x3)
8 x 15cm (4x2)
10 x 8,8cm (5x2)
8 x 3,7cm (4x2)
8 x 53cm torpedo tubes (2x4)
The next design in the series enlarged the dimensions and displacement again
and altered the layout to fit another triple turret aft. The doctrine for these
ships would be to flee from any ship or group of ships that could inflict
serious damage to the ship. Having six guns aft would increase their chances of
escape. Other improvements included the raising of the freeboard by a meter, the
fitting of aircraft handling facilities and an even more powerful propulsion
system. Leaving out the Deutschland type armoured cruisers, and introducing the
Admiral Hipper battlecruisers with 12" guns at the 21,000 ton limit, would the
Germanic States have gone down to the 11" gun? My feeling is 'No' they would
not. So the triple 12" is the likely next step up from the twin 12" on the
Hippers.

What eventually got to sea in late 1938 added even more improvements including a
new 'Atlantic' bow, redesigned bridge structure to mount the new AA directors.
