Here are the characteristics: appearance looks like enlarged to H-39
H45: 627.843 tons (LT 617.927, 692.078 ST)
H45: 609.6 m (2.000 ft 0 in)
H45: 91.44 m (300 ft 0 in)
H45: 30 knots (56 km / h)
H45: 30,000 nautical miles (56.000 km) at 19 knots (35 km / h)
H45: 8 x 80.0 cm (31.5 in) guns
12 x 24 cm (9.4 in) guns
remaining number of canons at an arbitrary but its length probably enough.  |
when it comes to H-45 there, I only have a sketch and a little more information
Displacement: (700,000 tons planned) 462,750 tons light; 484,920 tons standard; 560,057 tons normal service; 617,927 tons full load

Length: 2,000 (609.60m)
Beam: 300 (91.44m)
Draft: 55 (16.75m)
Armament:
Main: 8 31.5 (80cm) Gustav siege guns (4 x 2)
Secondary: 12 9.45/73 (24cm) Long Range AA guns (12 x 1)
Tertiary: 24 5.04/60 (12.8cm) AA guns (12 x 2)
Light: 5.5cm/77 Gerat 58, 30mm AA guns

Armor:
Belt: 14.96 (380mm) Deck: 14.96 (380mm)
Turrets: 25.96 (660mm) Conning tower: 24.8 (630mm)
Machinery: 8 shafts, (480,000 shp planned) 498,735 shp/372,057 kw
Performance: 28 knots; Range: 30,000 nm @ 20 knots
Complement: (5,000 planned) 10,236 13,307
Distribution of weights:
Armament: 16,425 tons = 2.9%
Armor: 158,660 tons = 28.3%
Machinery: 11,931 tons = 2.1%
Hull, fittings & equipment: 274,955 tons = 49.1%
Fuel, ammunition & stores: 97,307 tons = 17.4%
Miscellaneous weights: 750 tons = 0.1%
This is a 700,000 ton German battleship built to carry a battery of eight 80 cm/31.5 guns, the siege gun Gustav. This is strictly a flight of fancy taken from remarks made by Hitler that he wanted to mount 80 cm guns on the H-class. It was estimated that it would take a 700,000 ton ship to mount them.
Rate of fire for the main battery would be quite slow, one round per gun every five minutes or more while the AA defense would be much more rapid. The AP shell weighed over 15,000 lbs with 441 lbs of burster while the HC shell weighed over 10,000 lbs with 882 lbs of burster.
The 24 cm/73 AA armament was based upon a Kriegsmarine late war study to develop a land based high altitude gun firing a 300 plus pound shell up to 59,000 feet. It is possible that a 700,000 ton ship could carry twelve of these in single double purpose mounts, partly to make up for the slow rate of fire of the 80cm main battery and to engage cruisers.
The 5"/60 were probably Germany's best AA weapon at the end of the war and would have served this mastodon well.
The 80 cm weight of shell is based upon reality. Initially, the 80cm gun was intended to bombard the Maginot Line but as it was not completed in time, it was intended then to use it against Gibraltar. As Spain would not give right of passage to German invasion forces, the Wehrmacht took the gun(s) to Russia and bombarded Sevastapol and possibly Leningrad. The Gustav fired approximately 46 rounds in two days and inflicted incredible damage.
The turrets on this ship are so huge in order to provide sufficient room to handle absolutely giant shells and hold the extremely extensive and strong hoist and rammer facilities needed to fire the shells.
There is no detail information regarding the ships power plant. The total SHP required for a ship of this size dictated at least 8 shafts. Based on the extended range of these ships it would appear that a portion of the power plant was diesel.
This design does not compute when plugged into Springsharp. The numbers in the weight distribution are extreme estimates.
--------------------------------------------------------------------------------
The sketch is based on the results.
This is KM Fuhrer.
A ship that is potentially just as dangerous to handle the guns by the crew as the ones that are on the receiving end by it.
Another detail.
Eventhough Schwere Gustav and Dora had caliber lengths of 40 calibers.
The Fuhrer uses the naval standard 52cal 800mm guns.
I used the KM Bismarck for size comparison.
