In your humble opinion
 

What is the best submarine in the world?

For me the best submarine is the german type 214 or 212 i love them boats the second being the russian Delta IV class SSBN.

There's always a long line for the Nautilus.

Hmmmm....depends on your classification of the word 'best', I mean the 212 and 214 are probably some of the quietest boats in the world...but I would choose an Alfa over them because of the radical design and beauty of the boat.

After that monologue though, I think I would choose the Oberon (Gods, what a surprise!!), with a close second being the Sierra II. Dunno what it is about the Sierra II, but she has a hold on me. :D

Me like the Delta, too. If only it didn't have such a weird rudder.....
But the best (and I know its not a kilo) has to be:

second (maby first) fastest sub in the world.
quietest nuclear sub in the world.
most expensive sub in the world.
Deepest diving SSN in the US fleet.
most advanced sub in the world.

beat it.

I have to point out that the Alfa is not only faster than the Seawolf, but it is also the deepest diving for an attack sub. 2500 feet last I saw, and it will do 45 to 50 knots. Of course my data may be old, but I know it beats the Seawolf in those two areas.

Here are the Alfa specs:

Laid down: 1974 Launched: 1977 Commissioned: 1977 General Characteristics Displacement: 2300 tons surfaced, 3200 tonnes submerged Length: 81.4 metres Beam: 9.5 metres Draught: 7.6 metres Propulsion: OK-155 or BM-40A, 155-MWt Lead cooled fast reactor
40000 shp steam turbine, one shaft Speed: 18-24 knots surfaced, 43-45 knots submerged Depth: 800 m test, 1300 m crush Complement: 27 officers, 4 petty officers Armament: Six 533-mm (21-inch) torpedo tubes:
18 SET-65 or 53-65K torpedoes
20 VA-111 Shkval torpedoes
21 SS-N-15 cruise missiles
12 SS-N-16 cruise missiles
24 mines

1300 meters = 4265 feet (That is deep)

45 knots is damn fast too. that is just barely over 51 MPH. Getting close to torpedo territory.

Depends on place, time, environment, and the comparison of the efficiency of the sonar suits of both competing boats. Your choice is not invulnerable, and can be beaten.

I probably would also choose the 212/214, if I could choose the place. Can't get any quieter than this, currently, and some grim armament possible.

If needing to patrol globally, I probably would choose a nuclear boat, too.

At that speed it would not trigger additional attention if they had attached a siren to the nose like those StuKas once had. :lol:

Plus, the Alfas have all been withdrawn from service. I'm forced to agree with ASWNut101: Seawolf.

The Alfa isn't a quiet sub anyway. They created the Mk48 to go to 3000 feet+ just to catch it since I don't think stealth was on the drawingboard when this thing was designed. It was designed to come in, do its business, and then get the heck out of dodge before it could be attacked. at 45 knots, a torp would have a hard time catching it was the idea.

Dont want to spoil the fun here but the al'fa could only dive to 750 meters it was the mike class which was routinely diving beyond 1,100 meters.

The alfa was a interceptor submarine not designed to take on any submarines but to take on small task groups by out diving and out running weapons and ships.

Yes, and while it is racing, it is deaf like my dead grandpa. Such tactics are not my cup of tea. I prefer to be a ghost. And when I think of it, I played almost all sims, even strategy games that way, hell, it's even true for my way of playing chess, in a way. Takes more time, but gives me victory with far lesser losses, usually. One can only hit what one can see.

Subman, I said deepest diving in the US fleet

And I garentee you that the Seawolf goes ATLEAST 40+ knots. Does the Al'fa have a 20 knot tactical speed, too?

Yes the 212 is good, but its like a kilo:

Uses bateries (you can call them that, i know they are hydrogen motors, like the cars)
problably not very deep diving
slow
not under-ice capeable
short range (dosent even break 10,000 miles, i think)

212 is the modern kilo: good for littorials but poor choice for extended open ocean ops.

A 212 traveled from Germnany to Rota and back - submerged. Official depth is 400m, assumed crush depth is 700m. Even expert sites vary massively in their opinion on how long it can run submerged, and how far it can reach. That is understandable, for we can safely assume that the German navy keeps this data secret. So when you read this or that value anywhere, take it with a grain of salt. I repeatedly heard, red and saw on TV that the sub at least satys up to 3 weeks underwater. but again - read what I just said before.

In German service and use, the boat is planned as a globally acting intel-platform. Draw your conclusions. even a much smaller Type 206 has travelled into the Carebean some years ago to participate in a local excercise.

I think it is not a bad cjhoice for open water operation assuming it is dueling with another boat, in such a duel duel it would be an exceptionally good choice - for it is quieter than any nuke boat, and open water means there is no terrain around where you can hide (however, of course it can be outrunned by nuclear boats with their higher maximum speeds). Under such combat conditions one would assume: the quieter the better. But since a 212 is not meant to chase after a racing enemy, open water operations are probably not really it's domain. On the other hand: in world war 2 german boats managed to score their hits even on fast moving convoys and warships by appropriate planning and approach.

Skybird the critical piece of information you ommited is how long it took!My guess a ouple of weeks.I am sure they would not run down the English channel submerged.
The most important ting about speed is noise.There is no point being quick if you are noisy and cannot hear anybody else.
The reason the RN went for pumpjets was noise-their missions emphasised noise reduction not speed.
