Design Off?

Looks interesting! Those little fans are going to have to be spinning awfully fast to lift her though

Someone mentioned C-130's operating off of carriers in another thread -- not very practical of course, since the entire deckpark must be cleared.

So... I was wondering exactly how big a carrier would you need to operate tactical transports off of routinely.

It's not exactly a submersible carrier... but it's large!

I started with a Jahre Viking sized ship, and superimposed a rough deck with overhang. Scales are approximate.

No, I'm not suggesting we make a carrier out of the Jahre Viking  
That wouldn't be feasible or even desirable for a variety of reasons. This is just a hypothetical ship of similar size (although it wouldn't need such a large draft).

The idea is not a combat vessel but a mobile offshort support / logistics hub

The C-130s are deckpark only, the elevators and catapaults are for existing naval aircraft. If the C-130's had folding outer wings, you could stuff quite a few more on there though.

Killed the thread?

Burncycle, No, I hope not -- I for one have been very busy with a new job, and much of my personal work sits on a disembodied (disencomputered?) 500 gig hard drive, awaiting installation at home.

Well, for this to work we need to agree on something to design.

Well the subject was submersible carriers, but  I diverted it witht the VSTOL aircraft.

Somewhere, I think I have a SNAME paper about a 50-knot displacement monohull about that size. Cut down the power plant, and you could probably carry a pretty respectable air wing, and reasonably economical, too.

Obviously this 1970s continuation of the "Cruiser submarine" theme is hardly the optimum solution, but it has a certain menace I think.

Basically a large sub, approximately SSBN sized, with a helicopter hanger, SAM launcher (amidships in front of hanger), two AAA and 4 large anti-ship missiles that would be launched from above the surface.

Because it'd operate mostly above the surface I've optimised it for that environment which'd result in a relatively slow underwater speed.



The helicopter shown is a Kamov Ka-15.

I think that Norman Bel Geddes Streamlined Ocean Liner would be a good starting point.









I'll post some drawing scans tomorrow.

Wow! I like these designs!        

[GTX]

I'll post some drawing scans tomorrow.

Please do.  As well as information/details/specs.

More on the Bel Geddes Ocean Liner, as promised.









And as extra eye-candy a design by Otto Kuhler.


Cheers, Jon

Interesting cruise ship by Mr. Bel Geddes there. It looks like it would actually be happier submerged than on the surface. I presume that 'draught' of 120 feet is actually 'depth', because it's otherwise impossible, and the proportions don't tally with it.

Yep, should say 'Depth'. Corrected.

Howdy folks,

Long time (years, no kidding) lurker, finally decided I had something useful to add in.  This was my idea of a USN submersible 'aircraft carrier' a la 1950's technology.  It is intended to operate the Douglas model 640 fighter which really was intended to operate from a submarine platform.



Here's the Model 640:




Since I was stationed in Peru at the time I drew this (2003-04), I named it USS Paiche for the large (15-25 foot) and tasty fish found in the Amazon River at Iquitos where I spent most of my time working with the Peruvian Navy.  IIRC "Paiche" simply meant "fish" in Portuguese, and that name had arrived in Iquitos via the river trade with Brazil, which isn't too terribly far downriver from us.

I have a long backstory I wrote for Paiche, but can't find it right now. The hull designation was to be SSCV, but w/o my note I don't remember the hulll number I dreamed up, tho' it was one out of a sequence of unassigned numbers back then. I adapted the hull of  USS Triton and backdated it a bit to be a diesel boat rather than a nuke.  If I can find the story in the wreckage that is my household goods shipment from back then, I'll post it, if not I'll re-write it over the weekend.

At the time I wrote about Paiche, I had the large Japanese I-boats in mind, and being pretty much out of contact with the world and any reference material, let my imagination take over. The original drawing was simply pencil on a piece of printer paper, drawn on a rainy Saturday night in Iquitos. Some of you may have seen my orginal post on the original "never-were" warshipprojects forum around Feb 2004, but all that material was lost in a server crash right about the time I transfered back to the States in April of that year.  BTW, I really liked Planeman's 1970s rendition of the cruiser sub. Feel free to do same with this one if it so moves anyone, I have zero digital art skills as yet.

Diesel boats forever!
