The Norwegian frigate HNoMS Helge Ingstad has collided with an oil tanker in the Hjeltefjord near Bergen. The cause of the collision is unknown.
The frigate appears to be seriously damaged with a severe gash in the starboard side of the hull and it was beached in an attempt to prevent it sinking, but during the day the ship has continued to list and is now almost on its side.

Ouch. That's pretty horrible to watch. Glad there were so few injuries.

Good to hear there were no fatalities, hope the wounded were not severely so.

Norwegian report with video of her going down.

I wonder, were the tugs attempting to keep her upright and on the rocks/bar she was sitting on but the flooding just rolled her off? Or were they trying to pull her off before the flooding was contained, and as soon as she came off she went down?

I think they were actually pushing her further onto the bar, then she rolled once she was beached higher.

Could well have been. Sadly I it seems likely that the longer she's on her side, the more likely a write-off becomes.

Yeah, I think at this point, she's pretty much a constructive total loss. Just getting the hull straightened out and patched up would be a huge undertaking.

Fortunately, a lot of the electronics look to be dry, so maybe she'll be a useful source of spares for the surviving ships?

Quite possible. I've seen a few Norwegians griping on other sites that they were having trouble manning all their frigates anyway.

From the view on that video it LOOKS like the tugs pushed her too far over just before the rate of settling increased.

Ooof, she's further under now. Looks like the entire starboard side up to the base of the mast, and it's worse aft.

A lot of potentially useful spares are submerged, her entire CiC, drivetrain, and most of her weapons might be done for. The SPYs are still dry at least.

Makes me sick to see her like that. Looks like the only armament that hasn't gone swimming is the four NSM on the port side. Where does the SPY-1F transmitter sit? In the mast or lower down?

I believe the radar room would still be high and dry in the mast, at least as of that photo. But there's a whole lot of processing power and consoles below the current water line.

Well RIP. Those CFA's, Microwave sphagetti and phase shifters are bound to be wet by now.

Yikes, yep that's gonna be a total loss now of the radars and comms. She'll be completely submerged before they have her up.

Absolutely. Nothing salvageable at all now. Not even as spares.

Edit: Reading the VTS transcripts (even via machine translation) is maddening. The frigate's bridge crew seems to have had no clue that they were CBDR with another ship. Sounds like they were't even running radar, despite being in very tight pilot waters. All they had to do was slow down, or turn just a few degrees. Shockingly bad seamanship.

If they were relying solely on some kind of transponders... those things are not reliable both in term of data settings (manual inputs) and hacking risks. My guess is that they won't be the last (or are the first) to crash that way.

I doubt that's the issue. I think the frigate's OOD thought they could thread the needle between the rocks to starboard and a hard place (or ship, in this case) to port. But why the heck they didn't just slow down and let the Sola pass ahead, I can't imagine.

They were sailing close to land (fjord) so I guess direct directional GPS jamming wouldn't have been that hard.

Today DoD announced the priority upgrade of ANG F-16 in order to have their GPS Jam-free. Norway signaled experiencing Russian GPS jamming during NATO exercises. (https://www.c4isrnet.com/electronic-warfare/2018/11/13/norway-says-russia-jammed-gps-signal-during-nato-drill/ )

There's no way this is a jamming issue. It's a poor seamanship issue. They should have been able to avoid this collision just by eye, and radar should have made it child's play even without GPS.
