Likely the wake detection trailed on a T-boat a couple of years ago.


Am I being thick? But that is a T boat in the photo? Has this been seen on an Astute?
Seem to remember some of the sensors were on the sail last time though.

I think these have been seen before on a T boat, but on the sail, not sure which T boat was seen with them (it was a few years ago). loks like a new iteration of the previous system.

What's that?
Fortune favors brave sir, said Carrot cheerfully.
What's her position about heavily armed, well prepared and overmanned armies?
Oh, noone's ever heard of Fortune favoring them, sir.
According to General Tacticus, it's because they favor themselves…

T-boats are the Trafalgar class SSN's. Their names all begin with T.

It's a fair question after a mistaken identity of the sub briefly (which is understandable). So long as things don't spiral, I see no reason to relocate the posts.

I know what are Trafalgar class boats. I'm asking what's "WAKE DETECTION"?

Once you detect it (from afar), then you can fire wake-homing torpedoes into it
- ooops; we don't have any such

The Russians did (maybe still do) try sniffing for radiation to try and detect subs. However detecting meaningful tradition form the background sounds like an almost impossibly difficult task.

Wake detection uses radar or lidar like techniques to detect differences in water density, possibly caused by a submarine heating and mixing the water. Again very difficult to detect, and I imagine must generate lots of false positives. I guess these days they can apply some machine learning to filter out the false positives, which is maybe why the RN are interested.

An interesting read and relevant to recent discussions.

Watching part two of the documentary it states that they intend to keep the 971 Akula class in service of up to another 30 years. If it is t be believed they will have been in service for over 50 years when they retire! Sort of puts our retirement of the T-Class in to perspective.
