Alrighty, I'll add you to the list of credits when I get home from university and have access to the original drawing.

And thanks, its still nowhere near completion either with lots of small craft, civil vessels, utility vessels and ferries still to go just to flesh out the interwar fleet. Then there's the post war to think about...

Anybody here in particular good at drawing side, front and top views of various WW2 era guns? I'm not very good at it and looking at putting together a proper parts sheet for Sieranian vessels.

I primarily need drawings of the 130 and 120mm guns in both single and twin turrets along with various different AA gun types.

---

Also worked with the C3 cruiser design in springsharp more. According to the program it can survive 50 240mm shells along with 3 torpedos. Range is sitting at 8,000nm at 15 knots. Armour isn't too thick but seems to work well enough given the 240mm guns fire bigger shells than the Japanese cruisers that are the most likely opponents.

I could give it a try. Which mounts do you want to be drawn(RL,AU)? And if they are AU-designed mounts, could you give any examples of what RL mounts I should look on to get an idea on how they should look?

Well they'd effectively be similar to the Italian and Russian WW2 gun mounts. You've already done the 40mm and 20mm guns which are very useful (though I could use some front-on versions of the 40mm). Top views of the mounts would be good too as I am trying to work out how to do a top view.

Right now its the 120mm twin-mount fully-enclosed turrets for the C3s that I need along with AA weaponry and related directors. I only have single mounts currently and most of those on the destroyers are only semi-enclosed.

Casting ideas out there guys but I've been thinking (again) about the C3s and how to improve their range performance. Whilst Turbo-Electric drives are efficient, the steam plant still has some limitations though it certainly delivers power when needed.

For around the 1938 period, is the use of diesel cruising engines considered practical? I can't remember much on the diesels used by the Panzerschiffes though I know they operated independently. If I remember right, the WW1 German dreadnoughts were designed to have their centre shaft driven by diesel and the wing shafts by their steam turbines.

Would a similar arrangement work or perhaps some kind of way to work with the generators themselves on the existing turbo-electric system? The diesel provides the power needed for cruising but when performance is required, the steam turbines could take over. In such a scenario, the diesels are functional auxiliaries, also giving the ship power if the steam plant were disabled.

The Saratoga and Lex were Turbo-Electric and were capable of over 33 knots with a 10,000 mile range at 10 kts. Originaly designed as Battlecruisers (8x16" guns in 4 twin turrets) they were the largest Carriers in the US fleet until USS Midway in 1945 (indicating the ability to use a common hull and propulsion to build both BattleCruisers and Carriers for a significant cost savings, common supply lines, and common training for better crew deployment).
Other advantages being a shorter shaft line between propulsor and screw (less whipping in the event of a mine strike or near miss from a bomb) and the loss of a steam plant does not mean the loss of that propulsion line. This also allows you to place your power plant in the most efficient location on the ship rather than being tied to any specific shaft length.
This could also allow you to run only 2 steam plants for a more efficient peacetime cruising configuration to save fuel and wear/tear.
I would stay with the Turbo-electric system and even try to down size it for DDs...with smaller Frigates/escorts using the Diesel Electric setup that was used in submarines.
It would be interesting if someone who is better at math than myself work out the SpringSharp numbers and see if 2 Lexington type powerplants can be placed in a Heavy cruiser (10-14000 tons, 8" guns) and deliver the same perfomance.

(EDIT) This is a really nice AU. One of my favorites. Thanks for keeping up with it.

Well for what I have at the moment, the C3 design has 18,000t standard displacement and main armament of 9 240mm/9.45in guns in three triple turrets. The existing arrangement has two shafts and turbo-electric drives from springsharp giving a range of around 8,000nm whilst still allowing the ship to be protected against the 8in guns of the Mogamis and even has at some ranges immunity to the German 11in and Japanese 14in guns. Torpedo defences still need work as current survivability is around three torpedos.

Given that the ships are effectively capital ships built smaller and cheaper than the cost for battleship and requiring smaller crews, their need for long range had many uses, the most obvious being the fact that these ships are designed to operate throughout the Pacific as needed.

With the current twin shaft arrangement, there's about 152,000hp in total from the turbines. My theory has been to go with four turbines, two for each shaft with one per shaft in use normally for cruiseig and the second used to provide the increased power needed when in combat or in emergency situations. Auxiliary diesel motors located in the hull supplement these in providing redundancy in case of damage or flooding whilst also easing the electrical load from the steam turbines to allow them to operate more efficiently.

A three shaft arrangement may allow again for some more effective use of internal space in regards to machinery arrangement as well as more even distribution of power to the water, however with one of the 240mm gun turrets mounted over the centreline aft, bracing may be required around such a centreline shaft unless the shaft does not extend beneath the turret barbette.

Main issue is of course keeping the weight down as TE drive is heavier than a standard drive and has some power loss through the conversion of energy to electric current and back from physical energy. TE is mostly chosen due to its ability to allow all power to the shafts to run even if there's a loss of a turbine, improved ability to compartmentalise the hull to reduce flooding risk as well the inherit running efficiency of turbines at a constant speed. TE drive also gives the ship superior handling compared to the delay involved with conventional steam plants.

The destroyers may be somewhat tougher to implement such a plant though I've been trailing it in springsharp a bit just to see the feasibility. They have limited displacements which often means having to cut back on speed or firepower for the plant. The light cruisers I'm testing (which are similar to the Z plans M class cruisers in size and armament) don't have quick as serious of an issue however there are still some problems in terms of keeping things under the displacement limit.

Also here's two variations of the revised C3 design. For some reason V2 was giving 40t extra weight for gun armour in the main battery despite being identical thickness to the other design. I moved the midbreak well aft on the V2 design in an attempt to improve seakeeping, though this also now means that max range is 6,500nm at 15 knots instead of 8,000nm at 15 knots? Really not sure why the massive difference when the larger hull should cater for greater fuel capacity.

The V3 design is a hybrid of V1 and V2 and has the greatest range but also exceeds the 18,000t normal displacement limit I've been aiming for.

	   - Average freeboard:		19.31 ft / 5.89 m
	Ship tends to be wet forward

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 101.0 %
		- Above water (accommodation/working, high = better): 145.8 %
	Waterplane Area: 31,411 Square feet or 2,918 Square metres
	Displacement factor (Displacement / loading): 112 %
	Structure weight / hull surface area: 144 lbs/sq ft or 701 Kg/sq metre
	Hull strength (Relative):
		- Cross-sectional: 0.96
		- Longitudinal: 1.53
		- Overall: 1.00
	Adequate machinery, storage, compartmentation space
	Excellent accommodation and workspace room
Of these three variations, V3 has the best range and V2 has the best survivability. V1 is in between the two. I'm inclined to favour the V2 for its better survivability only if I can find a way to improve its range. At least 8,000nm would be desired.

Of note is that these ships are very similar in size to the Admiral Hipper Class however on a smaller displacement (and admittedly less firepower and armour), the Hippers achieved 6,800nm at 20 knots.

One thing you could try(I noted this only reasently) is that you could use the Armoured boxes over machinery and magazines instead of Armoured deck - Multiple decks. It should save some weight. Using a transom stern will also help increase range at high speeds.

I'll have to keep those in mind about the armour when I next have the PC on.

Reason for choosing the cruiser stern is that it improves performance in rough seas if I remember correctly and allows for improved hydrodynamics around the propeller shafts. It also reduces displacement aft.
