Well why didn't you post it in the appropriate thread then? That would've been the better idea..
Whilst I agree it could have gone in the F35 General discussion thread, but it does have some connection to this thread as Spain will most likely buy F35B's for the Juan Carlos LHD, it not totally disconnected from the thread.

Can we have questions around Mod decisions raised with the Mod via PM plse and not within the body of a thread

Some interesting info about the Turkish hull, my German colleague is working on the lighting spec, it's identical to the Juan Carlos, we also sold the lighting for the Canberras, it's different, apparently for the sake of speed the Turkish ship will be an identical sister to Juan Carlos and will use any of the updates that Canberras have.

When you say it's different in what way, placement/number/wattage or type?

Most of what is in the public forum regarding Turkeys new LHD, TCG Anadolu seem to indicate that it is very similar to the Juan Carlos 1 and Australia's LHD's.
I understand it will have only diesel engines and a communication system particular to Turkey.Weapons fit is apparently 2 x phalanx and a single RAM mount backed up with a number of med cal weapons..........Time will tell if fitted for,or with on completion of ship.
Visually the TCG Anadolu looks very similar to its cousins and and appears to have the same dimensions.
Would be interested if anyone has some info as to any individual peculiarities for Turkeys LHD.
With an eventual four ships across three navy's it appears the Juan Carlos class is a successful design.
I wonder if any other counties will sign up for this class of ship?

The Aussie vessels have newer lighting than Juan Carlos, the Turks are going for exactly what Juan Carlos has not the updated specification of the Canberras, the canberras are also apparently going to have all the interior lighting upgraded to LED.

From what I understand the original proposal had the ski jump removed, but due to the fairly big redesign this would have entailed and additional time they decided to keep it as per the original.

Our navy specialist has said the Turkish vessel will be all but identical in internal layout to Juan Carlos, whereas the Canberras are different internally,

I imagine for the same reason the AusGov decision to keep the ramp cost.

Yes that was the official line, the re-design and cost/time blow out to remove it was not worth it. The reality is that Navantia have the designs already done and market the ship in two different sizes with or without the ski ramp.

Make of that as you will, nothing implied on my part !

Also with regards to the lighting etc in the Canberra's, yes lighting, in fact all power is different to the JC1, they are set up for our requirements, IE 240v/50Hz

Cheers

Somewhere in the forum there is a link to all the Amphibous warfare ships by Navantia under the old name of Athlas Athas? The link show the different size of both LHD and LPD etc starting from 8000t and working its way up to the 27000t.

For the life of me I can't remember what the link was called, they had all the renderings with comparative ships in the class, but no idea if they got to the working drawings stage for the smaller designs.


Edit

Found it, and correction the LHD started at 13000t

http://www.infodefensa.com/wp-content/uploads/JCI_en_v2.pdf

- ATHLAS 26000: With displacement of between 24,000 and 28.0000 tonnes.. There are plans for LHD, LHA, and LKA versions, the LPD or LSD not being considered. The Spanish Navy's Juan Carlos I, and the two Canberra class ships for Australia are of the Athlas LHD 26,000 type. Navantia have presented a bid to Turkey based on a variant with displacement of 27,000 tonnes and possibly only with flight deck for helicopters.

Edited it just as I found the link for you :p My googling powers are too slow.

That said the class actually does start from 8,000t in design but they haven't built that ship as of yet. (Look up page 29 on that PDF)

8000 & 13000 ton LPDs, 13000, 20000 & 26000 ton LHDs. Only the 13000 ton LPD & 26000 ton LHD designs have been built, & probably they're the only ones with detailed drawings.

There's an artist's impression of a 13000 ton LHD in there, but no sign that any work had been done on it beyond that. It says " LHD, LPD and LPA options are planned".

The 20000 & 26000 ton flush-deck LHDs have been offered to navies, but I don't see evidence that working drawings have been done. Neither offer got very far.

In other cases where ranges of related ships are advertised by builders, they never seem to be ready to start building immediately. Detailed design & working drawings still have to be done.

There's a difference between the class design and the working drawings to actually build it. So I doubt anyone has done the working drawings.

From a structural point of view I have doubts about that line as well. The removal of the ramp will reduce weight distribution forward (with a resultant impact on longtitudinal stress and stability) but nothing that could not be compensated for at the design phase .... particularly if you plate over the entire focsle.

Thanks for pointing that out, I had no idea at all, really, totally clueless !!!

I really think some need to pull their collective heads in on not just this thread but the forum as a whole ! The amount of chest beating going on at the moment is ridiculous, and many of us have been around long enough on this site to understand each other, where they are coming from and their knowledge base to not feel the need to point out the obvious.

We have also been around long enough to know this very discussion has been had numerous times over the years as well

Anyway onward and upward......

As discovered on the AWD build where very little production design or engineering was budgeted. The powers that be anticipating a simple "build to print" were somewhats shocked by the result, even though I was there when this very thing was brought up at CDR and relayed to them.

Just quick question, after the working drawing are done are all designs validated by tank testing and can submarines designs be also tested in a tank to give an idea on flow noises?

a lot of the acoustic amplification is not generated by the hull - which is why subs get put into the chook shed... :)
