Radetzky Class Preliminary Project I

A few years ago I've decided to make drawings of all the KuK Kriegsmarine never-were warship projects from destroyers up to battleships and I did manage to make quite a few drawings on the numerous projects:

(Will intend to re-arrange them like making separate posts about the combined pictures)
And now lastly I finish this group with the left out class, the preliminary studies of the Radetzky Class Battleships!
And now the story:

The first meeting about a new battleship class was held at 1904, March 15. (almost a year after the launch of SMS Erzherzog Karl) where Admiral Hermann Freiherr von Spaun, Vice-Admiral Rudolf Graf von Montecuccoli degli Erri, Rear-Admiral Juliusz Franciszek von Ripper, Vice-Admiral Franz Freiherr von Minutillo, Rear-Admiral Anton Johann Haus and Naval Architect Siegfried Popper were participated. They decided to begin designing a new battleship class, though the construction could only be started after the current 3 was finished so around 1907 and Popper was instructed to start working on the preliminary studies for the new class.

The next meeting was done at the same year May 18 at Pola where Admiral Spaun noted that the construction could only start in 1907 and now only simple preliminary work was required to determine the hull and armament choices. It was set that the main armament calibre were to be either 30,5cm or 28cm rather 24cm like the previous class and the secodnary armament calibre was set at 19cm. Due to the new development of armour piercing shells the armour too had to be improved, together with this the displacement would rise by some 2.000tons compared to the previous class (10.600tons).
Discussions on placement of armaments was very fluid at this meeting, as the following ideas was emerged:
- 2 single 30,5cm Turrets
- 2 twin 28cm Turrets
- 1 single and twin 30,5cm Turrets
- 1 twin 30,5cm forward, 1 twin 24cm aft Turret
But in the end there were no definite decision was made armament wise.

By the Summer of 1904 MTK (Marinetechnische Komitee - Naval Technical Committee), Pola lead by Siegfried Popper produced six alternative plans. Of the 6 plans only one had 28cm/45 Main Guns (Project I) the rest were carried 30,5cm/40 weapons and none were equipped with 24cm Guns. Secondary armament was uniform 19cm/42 Guns and armour belt was decided on 230mm, with main turrets having 280mm face plates.

So this is the first of the series of Radetzky Preliminaries, the 1904 designs, where I've used the hull shape of the previous Erzherzhog Karl class but enlarged to Radetzky dimensions, two funnels because the wider hull allowed more space for the Boilers, and mixed Radetzky-Erzherzhog style superstructure elements. Added 66mm Anti-Torpedoboat Guns which was the standard calibre of the KuK Kriegsmarine at the time

The design had the following characteristics:
Dimensions: Unknown except the width so I've used the data of the Radetzkys: 137,5m (wl) 138,8m (oa) x 24,0m x 8,1m
Displacement: 12.650tons (standard)
Armour: 40mm Deck, 230mm Belt
Engines: 18.000shp Yarrow Vertical Triple Expansion Engines, 2 Shafts
Speed: 37km/h (20knots)
Range: 7.400km at 18,5km/h (4.000nm at 10knots)
Armaments:
2x2 28cm/45 Skoda K04 Cannons
4x2,4x1 19cm/42 Skoda K03 Guns
10x1 7cm/50 Skoda K10 Guns
3x1 45cm Underwater Torpedo tubes
