Escort see me without pinging

I just watched it, I felt very bad for the guys who did not make it.

It seems to me a terrible waste of resources. To take people with a decade's worth of naval experience, experience sufficient to even put one in the running for command, and then to throw it away because they were unable to pass the test.

I guess I can see this thought that someone rejected by "the system" might harbor resentments about that and try and sabotage the system in retribution, but I would think that someone able to make it into command school would be above that sort of thing.

I suppose they have more candidates than subs so they can afford to be choosy.

I watched too. Seems very stressfull. Yeah it really shame to be rejected after that long time and never be able to come back.

I'm also astonished by the up and down calesthenics of the periscope. I wonder today if they even use them with actual human-eye-optics.

I could see a periscope with a "head" made up of dozens of cameras that aim in a complete 360 degree circle, probably smaller in profile than an optical scope.

You pop this thing up above the water for 2 seconds, let it record hi-res images/movies, then pull it down and analyze it on a computer screen. Probably have a computer do relative motion analysis and tracking all by itself.

I sympathised with the guy who had fishing boats on the brain.

I have a similar problem with motor vessels off the East coast of England but, unlike the peacetime sailors in the film, I can at least sink them.

As far as I have read the Virginia SSNs and some others boats of the very latest models actually do have what you describe.

RN pioneered their development and they equip the Astute class subs.

Yeah I'm wondering too what they are using on the latest models and does they even use any kind of pericope which goes on surface.

I could also see this "photonics mast" being integrated into some kind of deployable tethered buoy, so you can get a peek at what is going on topside from the deep without having to surface.

Nowdays submarines are not so much interesting as the old ones when you have to manage with everything and such a poor conditions for crew

Yes that´s right. Because of the realy well sonar equipment we are not interested in "looking out" because we know allready who is around us. Type 212 passive sonar is able to detect the noise of propellers from coastal container feeder at ranges up to 100sm. Below 80sm the sonar is able to detect the lofar-noise of machine, gearbox, aux-engine. So why go up to peri-depth and look out, when we already know nearly all?

It would not be stable, I suspect.
