N. Korean Ship launch gone wrong

[Decky_Q]

I've been looking at the satellite images of the Destroyer launch. To me it looks like the bow section didnt release properly, the stern slid into the water deeper than expected as a result of the pivoting, bottomed out puncturing the hull, and falling over.

Anyone else have any theories? Agree or disagree?

Some people (and their families) are going to be having some sleepless nights.

Sleepless: as in 'dead'.

I wonder where you find that much blue tarpaulin. Can’t be easy.

Sideways launching is sketchy at the best of times, certainly more prone to incident than lengthwise launching; both are fraught with fk-up potential which is why many shipyards don't do dynamic launches any more. It's probably fit for bean tins and razorblades, but given the ste that the NKs have in their navy it may well be patched up and used for something just to save face.

Depending how much fitting out they had done - probably not a lot - it could well just be a case of refloating, drying out, repairing any holes and continuing with the program. I would doubt if it's damaged much terminally.

Sounds like the scapegoats have already been lined up for the firing squad.

Looked like the curtains from one of Kims palaces to me.

It will have a keel shaped like a dog's hind leg, as long as they don't mind it going sideways it'll be reet.

you just made me think, his suits are pretty big… maybe this is a bit of spare material from his tailor

Probably not.

Depends I guess, at that stage of build it was probably displacing somewhere between 1/2 and 2/3rds of her design deep end of life displacement.

If it was designed to some sensible sort of ruleset (LR, DNV, BV, ABS), which it probably wasn't, but some sort of sensible equivalent sort of design combined still water and wave bending moment for a warship, the hull girder will be pretty damn stiff and strong.

Yes, they've dropped it on its side, but unless they've managed to buckle all the internal decks, it'll probably still be pretty straight.

It'll certainly need some remedial work, but i doubt it's going to be scrap as a result of this.

I stood by two ships as Captain built in South Korea. All of the machinery and ancillary equipment was put in on a slipway, the accommodation was pretty much completed too. They were released down the slipway into the water for finishing off. In this case I would imagine they will basically have to start again with what is inside.

Good video here on the ship, it's class, state of construction, etc. Really interesting. The shipyard which was building it had no experience of building large warships, and more commonly built fishing vessels. Also unusual for them to launch sideways.

Video shows it was much less finished than that, they suspect it was rushed to meet a political deadline, as the other ship of the class was launched in a much more complete state last month, and it's suspected they wanted to show how quickly they could launch a series of ships.
