So.. basically , the so-called brutal submarine US advantage even in detecting them is not really that important given the torpedoes?

I did not know about it.

The new delivery systems of the submarines make it very easy to launch at least one nukes before being hitten...or at least this is my understnading...but I had no idea that it was related with torpedoes?

What do you mean by torpedo advantage?

I will have to look for a decent link, but reportedly the Russian Navy successfully developed a supercavitating torpedo, whose one big advantage is speed.

There you go: VA-111 Shkval - Wikipedia, the free encyclopedia

Deployed in the early 1990s, although previously operational, the Shkval is designed as a countermeasure against torpedoes launched by undetected enemy submarines. It may also be used as a counter to incoming torpedoes whereby it is launched at the enemy submarine, forcing it to evade, and hopefully cutting the guidance wire to its own torpedo in the process.

The speed of the VA-111 far exceeds that of any standard torpedo currently fielded by NATO. This speed is a result of supercavitation: the torpedo is, in effect, flying in a gas bubble created by outward deflection of water by its specially shaped nose cone. By keeping water from contacting the surface of the body of the torpedo, this significantly reduces drag and allows for extremely high speeds. In effect, the Shkval is an underwater missile.

Launched from 533 mm torpedo tubes, the VA-111 exits the tube at 50 knots. Shortly after, its rocket ignites and propels it to speeds of up to 200 knots. Some reports indicate that speeds of 250+ knots may be achieved, and that work on a 300 knot version was underway[1].

Guidance was nonexistent in initial designs, as the missile was intended for nuclear warhead delivery. Later designs reportedly include terminal guidance and conventional warheads of 210kg (460 pounds)[2].

Ohh I see.

It is atechnology whcih combines attack and defense. Teh relevant part for the SCBM platform is the ability of countermeasure to ahve time to deploy the missile..

This is why it is related...

Great info Dodo.. really great info... It is going to the main diary...

Actually, if a 688 received order to engage an old delta, the delta would be sunk before it knows it's being stalked. Almost the same for the typhoon. The Akula is a different matter (caution: the russian name for typhoon is akula, but i'm using nato code, so akula is the class of the kursk).

I'm not sure there is much torpedo advantage. To my knowledge, the supercavitation torpedoes are not considered mature enough for wide scale deployment. Plus they're useless without a nuke in the tip.

AIP diesel subs are teh shit nowadays, not the old nukes, sad as that makes me. The Americans have leased one of ours, the HMS Gotland, with crew and all, and they have had vast problems finding it.

We even managed to sink the USS Reagan, a supercarrier.

You don't have to be a genius to draw some conclusions. The Swedish Navy hunt Russians subs. The Russians test all their new subs in the Baltic. The Russians sell all their new (diesel) subs to China. The Americans lease a Swedish sub with crew and all.

They may be very quiet, but they are also limited, unless you are running them in limited waters. the big problem is that they have to recharge their batteries. that involves generally coming up to the surface and poking some form of exhaust out of the surface of the water. this exposes the submarine in two ways, firstly it pokes a highly radar reflective item above the surface, secondly it dumds a heated exhaust plume into the ait, where there is no boat. The fact that your submarine is spectacularly quiet is not much help if an aircraft 30 miles away can dump a rocket delivered torpedo with some form of active sonar detection on the fornt end.

Aircraft have always proved far more effective at hunting submaries than any other platform throughout history.

Life should consist in at least fifty percent pure waste of time, and the rest doing what you please.

But that's the good thing with Air Independent Propulsion. You don't have to surface to recharge the batteries. You can stay below for weeks, as long as you have food and diesel.

Sure, they are not for the high seas or circumnavigation, but ours is a brownwater navy. And so is the Chinese, Iranian etc...

Yes, but...

Diesel and the likes are really a pain in the ass of the US Navy, because most real action takes precisely place in shallow waters and/or close to the coast (Persian Gulf, huh ?), and because the US carrier battle groups are notoriously ineffective at sub hunting (active sonars on US surface ships are quite backwards).

They had to invent the concept of tying a hunter-killer like the 688 to each carrier to have some ship capable of tracking another sub (with passive sonars) in the group.

And passive doesn't make it against a diesel in a silent ambush ("guesstimate" the course of the carrier and drift under like a giant submunition mine). Active isn't so good either against a 1000t submarine.

What you say seems to correspond to the state of affairs 10-15 years ago, and it is probably what was told as one theory for the Kursk sinking. But I see conventional warhead and steering capacity development mentioned.
