what of this for a CL idear

this one started life as 4.5" DD but ended up as 5.25" CL and shes good on paper but the armors a bit thin side well what do think of her

Uh...

She´s poorly armed for her size and her hull dimensions are off the track...... 7,77m depth for a 6kts cruiser and a beam to length ratio of more than 1:10?!


And.... I can´t help it.... Why do I get the feeling she simply is a weird and enlarged version of the latest design I posted here?!?!?

Looks like someone is copiing my designs here... Same year, armament, speed.....

Coincidence?

I doubt it.... :o(

I still doubt it...

Whatever you say, 17inc, but all main characteristics are equal except for her tonnage. I think it´s obvious...

You can build whatever you want, sure, and this SIM is made to see how people react to a design and copying is one possible reaction. But copying and copying are two different things.
When I lay her down in 1933 she´ll be finished in 1934 and you Intelligence Service might be able to get her blue prints or whatever so you can start designing you own version and lay down something similar in 1935 or 1936 but surely not within the same year 33....

But hey, maybe i´m totally wrong. I wish you could proof me wrong.

So what is your doctrine behind such a vessel? For what does Australia, having less tonnage for cruiser than the SAE, need a 34kn 6000ts cruiser with such a light armament? Every 5000ts Arethusa can shoot you out of the water - even a 3500ts Tromp is heavier armed, faster and offers similar protection. So what is the logic behind your design if it is not just a copy of my design.

Answer me these questions in detail and I´ll apologize for saying you copied my design.

you what to know why

(1) the RAN needs a long rang CLAAAs escort for my CVs as you know austalia , ops are in lage Oceans the Indian & the pacific so thats what the mackey is desing for as two the why the 5.25" or 5.24" gun in your case its a good DP it can take on ships and aircaft and all so if needed the the ship can go raiding she the best of both worlds long sea legs and rang to match like i side i came up with with the idear over a long time it all started with a othere class of CL with 6"guns much lager then the mackey the juneen and can it do 35.11kts hear i will put it up for you have a look at it.

17inc, since when is a ship that displaces 3,200t called a destroyer? Our treaty maximums are 2,000t for class 1 destroyers.

Also why does your cruiser have a 23ft freeboard? isn't that a bit high compared to others? Your seaboat rating is 1.72. The weather isn't that bad is it?

The cruising speed for your cruisers is a bit slow at 12knts if they are going to be escorting carriers. However the top speed is very good.

For an AA escort i think you should take your 'destroyer' design and make it a little bigger for some more range. The 4.5" gun is a better DP gun than the 5.25" a la Dido. (however we don't know that yet)

Your larger cruiser compares very poorly to my Fitti class. At 7,000t each i can build 28 of them :-)

"Your larger cruiser compares very poorly to my Fitti class. At 7,000t each i can build 28 of them :-)"

Quantity vs. Quality?

Let´s see.... Uh, the SAE could build 62,857143 7000ts cruisers... :o) I´m especially curious to see the 0,857142 version....without pantry, gateways, only one screw, half a rudder, only the left side of the forward funnel... *g* Interesting, indeed....

no way i just taken a look? at your CL

you could out bulidme yes but your a land power you will have to keep most of the steel for tanks and guns for the army you all so have to keep a eye on the other Eu players RA where as Austalia is bron form the sea like enland we have no land boders to look afthere so the army is the smaller to that of the the navy by the way this the 6" CL mark 3 desing

Indeed, Hooman. Only put what is truly necessary on that 0,857142 ship. Perhaps a bridge built into the funnel and scrap the rest of superstructure. ("*cough cough* Captain ! I cannot locate the enemy ! There is too much smoke here !"). I doubt that ship needs an anchors. So kick them off as well. What else can you kick off that ship ?

hehehe

I always wondered what a keel is good for?! So let´s kick it! ;o)

Btw, would someone please tell 17inc what happens if a 8000ts cruiser with a length to beam ratio of nearly 13:1 gets caught in really bad weather or catches a TT amidship?

11

Saturday, July 5th 2003, 8:21pm

Might as well remove the deck at the same time (wonder how long the ship will remain afloat in bad weather).

As to what happens to a 13:1 ship, I have no idea, but I get the impression it'll snap in two. Did any nation actually attempted to build such a ship (either model or full scale) or were they aware of the problems with
ships with such a length:beam ratio through physics ?

When you look at the lists of Japanese ships on the board, you'll notice that all my destroyers are 13:1. ^^;;
The current designs have been adjusted though.

I don't think that last one is too bad. This one could give the Japanese CLs a run for their money. I doubt you'll need the torpedo bulkhead on your CL. It just eats up hullstrength and space (at first I was wondering why your ship needed 157.3 % for magazines and engineering). It does not positively influence the number of torpedoes you can take.
