As i start to watch, all i gotta say is: I'd love a rundown on the submarine fleets around the world. That'd be a great watch!

Does anyone have an ID of the sub at 17:20? Looks like the mexican flag, but as far as I know Mexico does not have submarines.

I think I am de-evolving. I found this submarine stuff to be really interesting. I usually shop for Hello Kitty and designer handbags.

Isn't a big part of how compact Soviet submarine nuckear reactors that they just weren't as heavily shielded as their American and NATO counterparts?

Perun, if this is true, why are the Russians having the Ukrainians make so many of their surface ships submergable?

It seems that the most likely viable military infrastructure is a rational portfolio of diverse alternatives that can best mitigate the risk that any weapon platform might be rendered obsolete by breakthrough technology. Small investors in this context will always be much more vulnerable, especially if they are deeply committed to particularly long term projects. I assume that agility is becoming increasingly critical to security.

Sorry, but I only see LIDAR as applicable in relatively shallow waters, 200 - 300 metres or less, much less in more turgid seas like say the UK Coast of the North or Irish sea for example.

Why? Because while it may be a laser system it is still light based, and attenuation is an issue. There is absolutely no way anyone will be able to convince me that a LIDAR system will be able to detect a submarine even in clear water at say 600 metres for one very simple reason. 600 metres is 400 metres deeper than the 'Photic' Zone assuming clear water. Let me be frank here, if the laser system is THAT powerful you may as well be using it as a weapon, not a sensor.

As a system it may well be valuable for detecting and attacking submarines that are fairly shallow, but all a submarine has to do to avoid LIDAR is go deep.

There is a REASON deep sea exploration, including communications is all umbilical based, because water attenuates electromagnetic waves of all kinds, and that is assuming the water column is homogenous. And that right there is the issue, it is not. Thermoclines form at multiple and often wildly variable depths depending on the area (or not at all in some shallow and well mixed seas), and the boundary layer of a Thermocline plays holy hell with any electromagnetic detection system including both RADAR and LIDAR as well as SONAR.

Cool. Like everytime.

Unless we get to a point where space travel is possible or governments start thinking about putting secret permanent underwater military bases or missle sites 20:10 I don't ever see the submarine becoming obsolete. If I had my own country and could only pick one type of hardware to use for my navy I would always pick the submarine. The stealth, speed, firepower, endurance, and ability to move assault teams. Nothing compares to a nuclear sub.
Great video as always keep up the great work sir. We all really appreciate your efforts !!!

Perun, no pressure but we are all waiting for your video while making coffee
