Are the stats accurate for the ships on the site that started all of this? And if so when where they decommissioned? Also, just for you Crazhorse, here's a (very good) artist's idea of what the battlecruiser 1939 project would look like:
Speaking of the Dutch Navy, I think I found some model names for them: for example the great war design "project 743" class battleship which was designed by Krupp-Germania. Here is a picture and stats:
Displacement: 21.300 tons normal displacement
Crew: About 1000
Armament 8 x 343 mm/L50, 12 x 150 mm L/50, 14 x 75 mm L/50, 4 x 533 mm torpedo tubes
Max Speed 22 knots
Performance 34.000 SHP
Boilers 9 Germania - Schulz watertube boilers
Machinery 3 Germania turbine sets, (1 set consists of a high pressure turbine and a low pressure turbine)
Range 8000 nautical miles @ 12,5 knots
Bunkerage coal and oil 4600 tons
Armor Belt: 80 - 250 mm
Barbettes: 80 - 300 mm
Deck: 20 - 50 mm
Conning tower: 400 mm
34,3 cm turrets: 50 - 300 mm
15 cm turrets front shields: 100 mm
75 mm mounts: 50 mm
Here's a picture of the design:
Then there was the Krupp Germania Designed "Project 753", here are it's stats an picture:
Displacement: 22.000 tons normal displacement
Crew: 1015
Armament: 8 x 343 mm L/45 guns in two quad turrets, 16 x 150 mm L/50, 12 x 75 mm L/50, 3 x 533 mm torpedoguns
Performance: 40.000 SHP
Maximum speed: 22,5 knots (average)
Bunkerage:2500 tons oil, 2000 tons coal
Range @ 12 knots 6000 miles with 2 oil fired boilers
8000 miles with 1 oil and 1 coal fired boiler
Here's the The November 1913 specifications (another propsed battleship):
In August 1913, a new cabinet presented itself to the public. The new Minister of Naval Affairs was the naval officer Captain J.J. Rambonnet, the same man who had opposed the inferior Pantserschip 1912 so vigorously the year before. Rambonnet's input led to a revision of the specifications. On November 13, 1913, the Committee again met. The results of this meeting were specifications along the lines of the Krupp designs. Displacement was set at 22.000 tons, with a main armament of 8 x 343 mm L/45 guns, and a secondary armament of sixteen 150 mm L/50. Twelve 75 mm L/55 guns were included, as were two torpedo tubes. There was a possibility that the latter would have to be increased to four tubes, with an additional in the stern. Belt armor was set at 250 mm, thickest over the machinery spaces and thinnest in the bow and stern. Conning tower and turrets were protected by 300 mm of armor, and the casemates for the 150 mm guns had 150 mm. Turbines were preferred, but triple-expansion engines were also considered for financial reasons. This propulsion plant would have to generate enough power to provide a speed of 21 knots and an endurance of at least 5000 miles at 12 knots. The crew numbered 860, of which 110 were officers and non-commissioned officers. In March 1914, eleven dockyards were asked to produce designs.
Afterwards the specifications where increased to these:
That same month, the Commission again revised the specifications. Displacement had risen to 25.000 tons [4], with a maximum speed of 22 knots. Endurance was increased to 6000 miles and the calibre of the main armament to 350 mm. The main reason to increase the guns' calibre was that by that time, it had become known that the Japanese battlecruisers of the Kongo-class were to have 356 mm guns. In addition, this calibre was manufactured by the preferred supplier, Germany. The thickness of the upper belt and side armor of the casemates was increased to 180 mm. In comparison to foreign designs such as the British Royal Sovereign, the Dutch battleships were about the same size, but inferior in armament and especially armor thickness.
Some seven companies submitted their designs, three of which were seriously considered.
Krupp-Germania design project 806:
This dockyard worked relentlessly to make improvements and came up with the most effective design. They proposed a ship with two high funnels and the eight L/50 main guns in twin turrets, two forward and two aft. The 150 mm guns were placed well above the deck, with a wide arc of fire. It had seven boilers, which produced steam to gear three turbine sets and three shafts. They thought to be able to deliver this ship in 28 months, and to impress Dutch officials, the company showed a readiness to work with the Dutch industry extensively. That was very important, since there were plenty of supporters for the idea to construct these ships in the Netherlands. It is unlikely it would have come this far, the Dutch shipbuilding companies didn't have any experience with building warships of this size.
Blohm & Voss design 733 A, B & C:
The Blohm & Voss dockyard in Hamburg came up with a design which included four instead of three shafts. Since they had gained a lot of experience with building battleships and battlecruisers (they were also designing the battlecruiser Mackensen at the time), the company thought they could deliver in 27 months. The main battery would consist of 350 mm guns with a length of 45 calibres, mounted in four twin turrets. Like the Germania design, it included many technical innovations. The readiness to work with Dutch companies was demonstrated by this dockyard as well.
The Vickers designs 694 and 695:
The Vickers counted on the Dutch desire for German guns on their ships, and designed their turrets in a way, that both British and Krupp guns could be placed in it. In case of Krupp guns, the magazines had to be altered and enlarged. Design 694 was a two-funnel design, the 695 had only one. The Vickers company also thought to be able to deliver their design in 28 months, which had a displacement of about 22.750 tons.
