Considering it's in very shallow waters and right next to the coast, would it be feasible to repair the hull and float it again? To scrap it, not to bring it back in line.
Hate to see all this good hardware wasted...

She has now sunk... game over sadly

She will be raised and taken to a dock. Then deammunitioned. Then surveyed. At which point, I suspect the repair cost will exceed that of a new ship. Not to say they'll get a new ship.......

This may have been mentioned earlier in the thread (haven't time to check) but there is a transcript and radar video around, that seems to show that the frigate had her AIS turned off until the very last moment, ( in stealth mode) so that the tanker and VTS (Shore control) had no idea that she was there, seeing only an 'unknown ship' approaching on radar. The frigate seemed to have no awareness of the tanker's position nor was willing to take instructions from her. They also seemed frightened to turn even slightly to starboard as instructed, ( due to fear of the shoreline) which would have narrowly avoided a collision, but instead turned to port across the tankers bows thus ensuring the collision. The frigate seemed be surprised eve after the collision, and to not even know what hit her. Her AIS was turned on only at the moment or shortly after the collision. Complete and utter lack of situational awareness and procedure, implying complete incompetence. This is very surprising from the Norwegians, (though the US Navy has form)

If you want an idea of what happened read up on the collision reports of the USS Fitzgerald and USS John McCain in close in coastal waters of Japan in 2017.
The collision reports can be found on the internet, this link gives a summary of both:

Was flagged (oops) at Post 36, actually. ;)

A slightly different source, which always/sometimes adds value, though!

Interesting question, I would have thought It has to be salvaged, one it's carrying munitions and two it will be carrying a lot of sensitive if not secret hardware, not something you want sitting in shallow water and close shore where any Tom, Dick or Ivan can swim out to, plus I cannot see you breaking it up in situ as again it's carrying munitions and will be full of fuel, the leaks were reported earlier as aviation fuel, so you will still have the main ship fuel onboard unless you can debunker it in situ.

I'm guessing they'll build some sort of cofferdam around the wreck - install some temporary patches and pump out the water, then let the water back in and re-float it.
The math on scrap vs. repair changed pretty dramatically when when she completely sank - basically each deck that is flooded significantly increases the repair costs. Previously I expected they'd repair, now I'm not so sure.
I'd be very surprised if they the wreck where it is - but as a minimum they'll have to go in and remove all the armaments and ammo (even as destroyed as the Arizona was at Pearl Harbor, they salvaged the surviving guns and ammo).

When you look at the efforts the Norwegians went to to salvage the old Soviet cruiser, I can't see them leaving it there

Quite a task. Guess they hope it doesn't fall off into the depths! :uhoh:

If it could ever be repaired after immersion for a week or two, I can't imagine it would work reliably. Who knows how much other fancy electronic gear is inside? Guided missiles?

What mixture of salt water and fresh, I wonder, up at the surface?

The Aegis is a suite of radars and missile systems. The ones fitted in the Norwegian destroyers are smaller, and nowhere near the costs for a full shore-based BMD installation. See: https://mostlymissiledefense.com/201...cember-7-2012/

Edit: From Wikipedia:

SPY-1F FARS (frigate array radar system) is a smaller version of the 1D designed to fit frigates. It is not used by the US Navy, but has been exported to Norway.
The size of the antenna of SPY-1F is reduced from the original 12 ft (3.6 m) with 4,350 elements to 8 feet (2.4 m) with 1,856 elements, and the range is 54% of the SPY-1D.

The 'Aegis' system on the Norwegian vessels are similar to the US Navy version in the same way a goldfish is to a shark. The arrays are considerably smaller, the TX units are less dense and the emitted power is but a fraction. Behind the array the power management would struggle to keep a regular SPY-1 radar warm. The processing power is similarly reduced to reflect the reduced area of the Aegis bubble around the ship.

That said they remain exceptionally capable systems and can totally dominate the area covered by their ESS missiles with capacity to spare. It's just that you need a massive increase in raw power to push the bubble out further and to process the increased levels of contacts, clutter, interference and hostile EW.

I have some experience with fire (smoke) and water damaged electronics.
There are companies who will dismantle wash dry & reassemble. In our case
mega-millions in 1980's no one would trust the stuff which was recovered.

When both lights you see ahead,
Starboard helm and show your red.

Or not.

Prior to the collision the frigate, which is one of five in the Norwegian navy, had been travelling around fjords for navigation training.
That's a fail then.
