Los Angeles class submarine

HI,

I try to gather as much information I can about Los Angeles class submarine ;
- which are the major differences in appearance then you can distinguish which of the submarine is when we see a photo ? ;
- has someone some more detailed photos with this class of submarine ?
- or where I can find some ?

THANK YOU

MARIUS

NOTHING , Nobody ?!

What is it exactly you need to know, Marius?

- Well if I have a HULL , how do I know what submarine from Los Angeles class is ? ;
- which are the major differences as outside shape between models of the same class of submarine?

Sorry I do not know if I did my self clear , or if I correctly expressed !.
I don't know that much English and "google is my friend" if You know what I mean !?.

MARIUS

Marius, I've sent you a pm about the MMB LA hull/deck kit.


Richard

hope you getting on better with your build than i am marius , i'm building one for a lad at work and have never seen such a bad hull in my life but i'll do the best i can with it

@tattooed ,THANK YOU.
I tray to NOT REPEAT the old mistakes and to do that I INTENDED to STRESS people on forum with lots of questions.
I sincerily hope to start with the right foot that build , and to share with me what ever You do on Your sub.
I need to get first as many information as possible , and Specialy Pictures to start working on hull as soon as I can , after end of January 2014.

MARIUS

I have been asked by Mark at MMB (Marks Model Bits) to point out that the hull mouldings that Andy commented on one post up from this one is not, as far we can discover, one of Mark's mouldings.

Andy doesn't know who made it, but it seems to be a different lay up to the MMB ones.

Hope this clears up any confusion as to who made the set of mouldings.



Richard(ADMIN)

as rich has pointed out the hull i'm building is NOT a mmb hull the lad at work got it off ebay and is very thin unlike marks which have a nice good layup

Actualy I am more confused at the begining.
I have these hull:











witch sub from Los Angeles Class is ?;

MARIUS

That's an MMB moulding, Marius...as I said in my pm to you, it's not based on any particular boat in the class, just a good representation of an LA class.

That gives you chance to research the LA boats, choose one you take a liking to, then do some more detailed research into that boat until you feel you have enough information to make a start on the building of it.

Richard

It represents a flight-1 LA class. First of the breed. Resin is very soft on the details -- all edges should be sharp, not rounded. And the stern plane bearings did not hang off the horizontal stabilizers like that. Deck engraving and raised detail looks about right in form, depth and height.

If the upper hull piece is as thickly laid up as the bottom, you'll need a life-vests amount of cork to float the thing (big ballast tank) if this thing represented a Soviet boat. Lucky for you the LA's required only a 15% fraction of the total displacement to float at the designed waterline -- very low freeboard, even for 'modern' American submarines.

Plenty of documents out there showing the proper arrangement of a flight-1 -- homework time.

THANK YOU for the answer,

The hull is SO HAVY ? .....what should be the size of the WTC to work properly?
If You are so Kind to point me/explain what it "fight -1" : Ia m not familiarised with the expresion !.

EXCOUSE MY IGNORANCE!.

No problem, Marius.

You'll need maybe a pounds worth of ballast tank capacity to get that boat up to waterline. Remember, its not the weight of the above waterline structures that dictates ballast tank size, its the displacement (thickness) of all the above waterline structures. It matters not a bit the density of the material ... it can be either foam or depleted Uranium. It don't matter!

That upper half of your hull kit, if as thick as the bottom we see in your picture, will displace a lot of water!

As with any military vehicle that is produced in quantity over time, the design will undergo up-grades and alterations to both suite changing operational requirements and advancements in the state of the arts involved in its structure, propulsion, and weapons. Such was the case with the L0S ANGELES class submarines. With the LA's these improvements have been identified by 'flight', or lot, or sub-class:

Flight-1 denotes the initial batch of boats. Identified externally by the tear-drop cross sectioned sail, use of sail-planes, and no anechoic tiles or VLS capability. Flight-2 saw introduction of VLS, flight-3 saw the bow planes introduced, replacing the sail planes. Also, these newer boats featured a ring around the tips of the propeller blades, and a slab-sided sail -- likely an attempt to dampen 'foil roll', this move to widen the high-speed turning envelop of the class. To confuse the matter there is some cross-pollination between the flights, so the above defining physical characteristics is not absolute.

Don't get bogged down in the small, stuff -- you're not that good a Model Maker yet. Just assemble the kit as best you can and get it into the water!

You're kit reflects a Flight-1 boat. Go with that. You get bogged down in detail you'll never finish the damned thing!

OK DAVID THANK YOU verry much . Now I have some materials to study.

MARIUS

I have the US Navy drawings of your sub.

YOU ARE AWESOME !!! . do you think is possible to sher with me those plans via email? .
I send You my address on PM.

I steel gather the materials , study pictures , take notes , stuff like that .
Unfortunately is going to be a long term build not because of complexity but because of luck of knowledge to do right thing .

Because I can't send a PM to YOU and My email Address is NOT a secret :

marius_petcu2@yahoo.com ,

now You can send me those plans if You wish

MARIUS

The drawings are in hard copy and I have to locate them in my shop.
I will get back with you.

OK , THANK You.
