Don't ask me why...but I've got high hopes for Ambush.

The space shuttle doesn't work very well under water, but the HMS Ambush does. Therefore, it must be more advanced.

Really? I knew you guys were fiesty blokes, but jeez......

And bigger but quieter, yet the "Hole in the Ocean" type sonar search will pick it out quicker then.

Maybe it employs active noise cancellation like the Akula to solve that problem? The UK has had quite a while to figure that little secret out since the cold war ended...

Dont forget the Ambush can still fire some eels even though she's been sunk!

is there anyway to hide a sub as a school of fish or a whale?
maybe by playing sounds in the ocean? or by changing the shape of the sub?

Anyone else having a problem with believing the claim that passive sonar type 2076 finds and tracks objects at ranges of 3000 miles...?

you mean when it leaves New York it can't hear ships in San Francisco!?!
Gasp!

It would be able to in SH3.

No, in SH3?
The DD in port at SF would see YOU!
Then it would ground itself and sink trying to get to you.

Right, I got that mixed up.

Not really, do this experiment: Talk to a friend in person then have them talk to you on the phone. Notice how they sound different each time. The speaker reproduces their sound but not exactly, it cuts off the bottom and top of the amplitude sine wave. Narrowband analysis can show this. But that is not to say that artificial noise can't mask a submarine's tonal by flooding the freqs around that with random noise.

Its possible but under very specific circumstances. In WWII detection of sounding charges were heard as far as 900 miles using the deep sound channel. Three SOSUS stations (Newfoundland was one) detected the implosion of the Scorpion near the Azores, thousands of miles away.

But I think the problem most of are having are the words, "finds and tracks"

I understand loud noises over great distances, or sound channels carrying intermittent sounds great distances. Detection is not the problem, tracking is. But isn't one of the problems with tracking through the deep sound channel the fact that range (Other than "It's really effing far way cap'n") is practically impossible to tell since it's actually based on some sort of harmonic? IE, the contact would be a possibility of ranges of multiples of say 30 miles, ie it could be at 60. 90, 120, or 150 miles, etc?
