Warships - Armchair Admirals ahoy!

dazzle camo not be in vogue as a means of defeating optical sensors

Not really. Modern image segmentation techniques will eat camouflage for breakfast, and the reality is that all you've got to do is stick an additional sensor into the mix (UV, IR etc.) and it becomes almost impossible to hide from it if you've got line of sight.

There's a lot of hype about using "dazzle" to fool ML algorithms, but the reality of these techniques is that even the flashiest, modern ones based on generative adversarial neural networks and whatnot are strongly constrained in the contexts they work and typically attack the problem of object classification rather than object segmentation.

You could maybe fool a sensor into classifying a part of a ship as something a lot more critical than it really is, in order to draw fire, but you're not going to fool a sensor into missing a ship.

Plus let's be real here, there is no combat warship with stealth technology worth a damn right now, so what's all this about "optical sensors"? The Zumwalt is a four billion dollar barge that will break down the second it's put into a combat situation, and everything else you can spot with conventional sensors to some extent (since we don't know exactly what the capabilities of these ships/radar are)

Not that it's any stealthier than a rusty soviet missile frigate. It's ten times the displacement, sure, but phased arrays don't care.

Missiles. Missiles you optical sensors. Though they do so in combination with other sensors as well.

As for unguided torpedos. I suppose best Korea still has them?

time to bring back dazzle camo imo.

Although the last time a ship was sunk by an unguided torpedo was nearly 40 years ago, given the development of countermeasures and sensors should dazzle camo not be in vogue as a means of defeating optical sensors and unguided torps?

not quite 40 years

It has a number of old submarines approximately that age, so it is very well possible that they still have unguided torpedoes.

Unguided torps? Seriously?

Falklands War, the Conqueror sank the Belgrano with a dumb unguided torp

Yes, thank you, we got that.

And, yes, we also know that happened 40 years ago.

Point is, 40 years is a very long time for a military that's not best Korea's.

Even Best Korea uses guided torpedoes.

https://en.wikipedia.org/wiki/Spearfish_torpedo is what we use now.

We used https://en.wikipedia.org/wiki/Britis...torpedo#Mark_X to sink the belgrano as the more modern torpedo had issues at the time.

Wohooo if anything can actually get the impulse for small fusion reactors it's this. Wouldn't it be hilarious if war saved us from global warming and the need for oil?
