"expert " fantasy?
More like ''expert'' bullshit. Just look at this:
....Husky boats will receive new "wet" torpedo tubes, in which water will be used to launch ammunition, and torpedoes or other types of weapons can be fired from a depth of up to 1 km....
...this is indicated by the possible depth of submerging the submarine to 1 km and its service life....
And what is stopping the enemy from blowing that submarine at the depth of 1km? I don't see the problem with sending a torpedo at that depth at the fraction of the cost it takes to build a submarine.
Back to missile/ship issue. One is infinitely cheaper than other.
And this:
....Boats will apply a wide range of both underwater uninhabited autonomous vehicles and unmanned aerial vehicles.....
UAVs on submarine? Don't the have bigger issues to solve? They are barely building current versions. Do they even know what subs are supposed to be used for?
It's like bullshit competition over there.
1km depth in a situation where they can't even build enough subs that can't even go half that depth.
Virginia-class goes just 240m deep but that doesn't stop USA from using them effectively because priority is lowering noise not going deeper.
And best of all they can build them by the shitload. Simply because they do not indulge in delirious obsolete fantasies.
Papa,
I have explained the importance of diving depth before. Let me explain one more time with an example.
One of the most important sources of noise from a submarine is "cavitation" from the propeller(s).
Cavitation noise decreases as the submarine dives deeper.
A rough example:
-If a submarine is doing 30 knots at 50m depth, the whole ocean is going to hear it.
-At 500m depth, the same submarine can do 30 knots and be virtually silent.
How does that translate in practice? Again let me use a rough example in USA v/s Russia modes of operations.
-Virginias tactics are to hunt at low speeds, they will use their max speed in emergency escape and run away situations.
-Yasens use high speed to quickly arrive within striking range of their assigned target (carrier group or other), they need to dive deep to travel at high speed while remaining silent.
And here is another reason why diving depth is important:
-Sonar performance is affected by sea water temperature.
-The ocean temperature is not uniform, there are layers of water at different temperatures.
-The deeper a sub can dive, the more it can use the various temperature layers to hide from enemy sonar.
There are several other reasons why a Navy would want to make its subs go deeper.
The Russians (and Soviets before them) are not making Titanium hulls just to be cool. They paid "an arm and a leg" (Titanium is expensive) to build Titanium hulled subs because they can go deeper. Titanium is also far more difficult to work with (welding for example) and requires more work-hours and specially trained people.
The Americans on the other hand attach less importance to maximum diving depth.
Russian and American submarine tactics and modes of operation are different. Hence, direct comparison of Russian sub X versus American sub Y is not very relevant.
