How to read this?

"17,000tons materials needed.
9 factories produce 9000t of materials "

Does it mean parts of your building programm are delayed?

At first i thought he had 9000 tons needed and 17,000 produced switched to 17,000 tons needed 9000 tons produced but if i read the building program correctly its only a maximum of 7000 tons needed, so your either missing 2000 tons of ships building, you accedentially reversed the numbers and went over 2000 tons on used materials or your quarterly report is incomplete.

How to read this; I have messed up my calculations but have now rectified it.

My reports are what is happening at the end date. For example at the end of Quarter 3 Francesco Caracciolo needs 700t to complete.

To me it seems as if your DD looks somewhat massive - at least its superstructure does - for a hull less than 12m wide.

I also think you could move A turret forward on the weatherdeck, install a VLS where A turret is now, add Harpoons amidship, remove B turret, install a hangar there with a landing platform behind and make C turret a twin launcher for standard SAM and you may end up with something very, very modern.... :o)

*just kidding*

Kind regards,

HoOmAn

PS: Sorry, couldn´t resist. For some reason the first impression I got was that of a TICO-class with guns...

What scale do you use for your pictures? I do tend to agree with Hooman, she looks very very modern.

The scale for my pictures is 1 pixel:200mm

If i remove the second funnel she looks even more modern. As to why she looks modern; scrub the flush deck, then draw a line between A turret and the bow. However this previous layout did not do her any justice. The super structure is a bit too big - so what? there is no armour there so it shouldn't be a problem.

It´s not a matter of weight but of size maybe. Try to make a top view. You might find out that you´re running out of deckspace for a superstructure 3 decks high aft if sailors should be able to use the deck around the superstructure levels for something useful. At level 3 the ships superstructure might be too narrow to be useful.

I also wonder about the torpedos. First they are not part of the springstyle sheet and second you might not be able to train them if they´re installed as suggested by the drawing. Torpedos had a length of ~7m during those days and with a beam of less than 12m you´ll might run out of deckspace if you try to install two launchers abreast each other - even if one does not take the superstructure into account that is visible amidship between the launchers.

What is the deckspace aft of B turret good for? Boats?

What is this tower-like thing that is placed on top of the DDs bridge?

Ciao,

HoOmAn

I could use the space aft of B turret for torpedoes but it didn't look right. maybe i'll change my mind.

The tower like thing on the bridge is just that; a tower, similar things can be found on Italian and RN destroyers.

I'll do a plan view and see how things look.

...shes a nice design but that bridge looks slightly large and even un-armored will effect your DD's stability due to its weight.

I've added a plan view to the picture and rearranged the torpedoes. looks a little better now.
