Re: PLAN submarines Thread II

Seawolf class were said to be designed to engage 5 underwater targets at once with torpedoes. The idea was to make effective ASW defence of the soviet arctic SSBN bastion impossibly expensive by making even a single penetration of the bastion by a Seawolf unbearably dangerous and costly.

Re: PLAN submarines Thread II

As the sub move forward, it has to reel in the wire, otherwise the wire would trail behind, scrape the hull and possibly foul the screw. If the wired becomes crossed and tangled, it might jam as it is reeled in.
It would reel in the slacking wires that are a short distance in front but would the submarine reel in the 10s of km of wires that are extended all the way through or it would reel in just the portion of the wires that are slacking until the torpedoes are released and cut off the rest of the wires.?

It would probably cut off the wire once the torpedo is expended.

However, if the two targets are in significantly different directions, then the wires for torpedos engaging them would likely cross very close to the submarines if they cross at all, unless the torpedoes are purposely steered in a roundabout course to avoid the wires tangling or crossing close to the submarine.

What I'm thinking is that, the wires can be programmed to be allowed to cross only when they are kms away from the submarine. This way the torpedoes have more flexibility in the way they maneouvre without having to be limited by the constraint that the torpedoes' path can't be crossed and that they have to suddenly change directions because of this constraint and losing the target for good.

Re: PLAN submarines Thread II

a little bit on the AIP engine installed on Yuan

basically said that they got a prototype as early as 1998 and the AIP engines come in the form of 20 and 100 kw. Of note, the stirling engines used on Gotland generate 75 kw each. So, 2 100 kw AIP engine on the larger Yuan would make sense.
That implies the AIP engine is good for low speed creeping only. 75KW is not even 100 horse powers. 2 100 KW AIP engines is only 260 horsepowers, less than available in most sports sedans. These are a tiny fraction of typical diesel or electric motor on a typical diesel electric sub.

Re: PLAN submarines Thread II

That's the case with all AIP equipped submarines. Modern SSKs don't emphasize speed but rather stealth, while modern SSNs should emphasize both, along with endurance.
An SSK equipped with AIP allows for stealth and endurance, but naturally low speed compared to an SSN. In a defensive position, low speed shouldn't be as much of an issue.
