The Daniel, a Destroyer-Class submarine takes the world of naval battle a giant step forward. The second ship produced by the Avi Shipyards, it is truly a work of art and talent. It took years to research and develop, and now its plans are finaly being publicized.

The Concept
We set out on a search to find a vessel so powerful, as too turn the tide of any naval battle. The Daniel was brought to the planning table as a submarine that will give its side a tremendous advantage in battle. The planners armed her to the teeth with 150 missiles, specially designed to be ejected from the under the water, and then to continue to fly along to their targets.

Specs:
Armament D-19 launch system with
150 R-39 missiles

Power Plant six Nuclear powerplants (A4W Pressurized water), Four shafts, Four Proppelers, five blades each
Length 850 meters
Beam 100 meters
Draft 40 meters
Displacement 90,000 tons Surfaced
132,000 tons Submerged
Maximum diving depth 500 meters
Speed 12-16 knots Surface
25-27 knots Submerged
Crew 750 men (190 officers)
Endurance 90-120 days

OOC: please give feedback, even if you're only going to say 'Its ok' (which I doubt).

OOC: I think steam turbines were found to be ineffective for submarines back in their early days. There were a lot of problems with propulsion systems until around the early 20th century. In fact, one of the first truly effective submarines (though I don't think it was THE first) was the USS Holland, which had the honour of being the USN's SS1.

The problem you're going to have with any submarine that isn't nuclear powered is the fact that you have to resurface to recharge batteries needed for undersea operations. When you do that, your sub is exceptionally vulnerable to attack. When a diesel-electric sub is underwater, it's actually quieter than a nuclear submarine, but a nuclear-powered submarine can stay submerged far longer.

It sounds like you're trying to create an extraordinarly lengthened SSN or a hybrid between a SSN and a SSBN. That's pretty infeasible because they fill drastically different roles. A SSN has to be fast for it to flit in and attack surface ships or other subs, whereas a SSBN has to be big and bulky for its role as more of a land attack platform. To get a sub to do both, you either have to make it too slow to be an effective attack submarine or too small to make it a credible SSBN.

That's just my take on the issue. I'd like to see other feedback from people.

OOC:

Personally, I would make it a touch samller and recrease the missile capability. This is beginning to sound like Arsenal from MGS2, if you ask me, and a bit future tech.

I would make it just bigger than the Russian Typhoon, but it itself is an extra large submarine.

It was made with the intention of being a major attack sub, not to be fast. Also, the sub doesn't have to be underwater to attack (it was modeled after the Russian Typhoon, check it out on Fas.org).

As for the propulsion, would 'Two Nuclear powerplants (A4W Pressurized water), Four shafts, Four Proppelers, five blades each' work out?

A submarine that's only short of a kilometre in length by a two-hundred metres is not an attack submarine, the Typhoon submarine is short of two-hundred metres and like most SSBNs is not capable of speedy turns or engaging in direct confrontations, so your boat is not an attack submarine in any conventional sense.

It's just an oversized SSGN, frankly something like this goes in the same catagory as super-dreadnoughts except this boat is inherently more vunerable as at least on the surface you see with your own eyes.

The Typhoon was the basis, but then I multiplied its figures. It requires assistance for protection, but has immense firepower. (OOC: Just like the Death Star: needs support, but is worth the protection.)

You are joking right? A 800m sub? :headbang: The sheer cost of the materials required.... ARG

So? How expensive do you think it is? Maybe I'm willing to pay the price.

bump for comments

Sarzonia, it is now Nuclear Powered.

Your submerged displacement is very, very low. Taking the average of the boat's beam and draught (70m) and the length of the submarine, one comes up with a rough formula for the submerged displacement, noted below:

volume = (pi) x ( r^2) x (h)
volume = 3.1416 x (70/2 m)^2 x (850 m)
volume = 3,271,183.35 m^3

and since one cubic metre of water has a weight of one metric tonne, that would be the approximate submerged displacement of this ship (i.e. 3,271,183.35 tonnes = 3,219,668.65 tons). Two A4W reactors would barely be able to nudge this monster forward.

So I should change it's displacement to 3.2 million tons? Oh, and I already changed the propulsion to Six Nuclear Reactors.
