My guess is they have had several contacts but have great difficulties pinning it down and finding out exactly what it is. These waters are really bad in terms of ASW ops. Lots of places to hide for a small submarine or submersible. I think something is really there (or was ar least) but they won't find it.

If it is a non nuclear sub it will have to go to PD soon.

(The correct spelling is buoy, if you are curious :p )

There is speculation in the UK that it may be a Kilo Class which is reckoned to be able to stay submerged for 10/11 days.

Well there are only 2 Kilos in the Baltic fleet, I think that competent people would have counted the ones away from the base (Kronshtat isn't that big a place).

And Kilos only have 140 hours or so at 3 knots, so 10-11 days is sort of pushing it.

I think it's a smaller than a Kilo. Some sort of mini submersible. It seems to be a vehicle that relatively easily can hide in cracks and crevices, and going by the numerous sightings it seems to have come to or near the surface to recharge or replenish oxygen a couple of times at least. Two new observations were made today apparently. Not sure what that means in terms of what they've seen. Lights and swells on the surface are two things I saw mentioned, but not sure how accurate that is.

Haha, fantastic. Those poor guys on NS Concord got a call from as Swedish reporter, and it was quite apparent that they were rather sick of having to deal with Swedish paranoia. They were drifting waiting for instructions from their company, so on one side they had their management sending them to sea to drift for weeks waiting for cargo, on the other paranoid Swedish reporters calling them, and most probably they've been overflown a few times by Swedish recon flights. My bet is that we also have a sub watching them. I hope they are paid well for all their troubles. :D

And now some kind of propaganda war is going on between Russia and Sweden.

Russian news paper are mocking the Swedes a.s.o

They must think we are nuts. :)

Maybe they do

Yesterday when I watch Aktuellt on SVT2 I was shocked

We haven't any of our HK4 left in our ASW-hunting group.(some of them are at museum)

They are or was our best weapon against submarines who are violating our borders.

Markus

Well aren't visbys sort of decent in the ASW role?

She is, there are however a big advantage in using a Helicopter for ASW than a boat, like the Visby.

A sub can't hear the helicopter, not before the sonarbouy starts to binging(or what it is called) A ship can be heard, even if it doesn't go fast.

Markus

For some reason I have thought that Visby had a helicopter capability, like our project 20380/5 corvettes but I guess I was wrong.

Nope, not a single one. I get the feeling that the big boys in SOG and the military high command together with the politicians figured we needed those cool looking Blackhawks so our Spec Ops guys and girls(?) could kick ass in style. They completely forgot that we have a massive coastline and that sometimes, neighbours and other interested parties come sniffing. :)
Not a single helicopter configured for ASW duty. I think that is hilarious considering our history.

Also, the Visby class is very competent in this regard. But the a chopper mobility is invaluable in a scenario such as this even if both passive and active sonar must be a real b**** in these waters.

No it does have helicopter ability, we just don't have any ASW helicopters. :D
