Wow, this explains it all! I currently live on the beach in Dakar Sénégal. About 2 weeks ago, I was up late on my balcony and saw these dazzling green lights coming from really far out in the ocean. For one I was wondering what it was, and two, I was surprised that the green lights seemed to be coming from so far out from the ocean, but yet they were lighting up the beach like someone was standing right there with a…

What’s the danger of blindness?

This is pretty much what the article is about.

Earlier quoted context omitted.

I imagine that it has rangefinding capability, and throttles the output based on distance to the target. It probably doesn't know and doesn't need to know whether the target is human.

That sounds reasonable, but the quite from OP says something completely different, it says "The laser rapidly determines if an unintended observer is within the nominal ocular hazard distance (NOHD) and immediately shuts off the glaring output to prevent accidental eye injury" - that doesn't sound like the mechanism you describe.

Sure it does once you run the original through a PR committee or two.

It sounds like the marketing speak a defense contractor would use to describe something that simple.

Who says that one isn’t intended to do that?

International Law? https://en.wikipedia.org/wiki/Protocol_on_Blinding_Laser_Wea...

The US has the 'Hague Invasion Act' if any US person is detained at the Hague so not sure if international law is a problem.

Two side observations unrelated to the laser rifle: 1) It's surprising or kind of amusing that such a huge and complex submarine uses plain old Raytheon / Raymarine radar when operating in harbor, etc. as if were just a little sailboat. But whatever works and is effective! I wonder how it has to be dismantled and put up, taken down each time? Perhaps it's mostly for being visible to other ships/monitoring stations? I…

That Raymarine unit is a secondary piece of equipment, and is there primarily for its transponder capabilities, which the primary radar unit (the AN/BPS-16, which I believe is integrated into the masts) probably doesn't have. The last thing a submarine wants is an enhanced "here I am!" capability.

Submarines, in general, rely primarily on their passive sensors- passive sonar and EW receivers. A submarine's best offensive and defensive capability is stealth.

The only known countermeasure is a Bedazzler vest.

>It's obviously propaganda but it is very interesting nonetheless. Sorry, how is this video obviously propaganda?

Ok so destin works as a scientist for the us gov. He did a video a while ago where he interviewed a general about the cyber domain of warfare. In this interview they discussed that the interview itself was part of that cyber domain, and the access they provide to destin is a part of the US presence in the cyber domain.

Marketing is propaganda is marketing.

Which term you use reveals your political leanings about a topic.

The US military isn't just doing it out of the goodness of their hearts. They want you to become a submariner! Or at least that's what I think he's implying.

Super fun job!

Unfortunately the US Navy has been beset by incident. Navigation of its ships is no longer a certain thing. Look for coverage on this matter which mentions the McCain and the Fitzgerald.

The Red Cross still considers them to be dangerous. The human eye (depending on the person) magnifies light 100,000-500,000 times. The inverse square law means that only minor variations in distance can have large differences in effective light (laser irradiance conforms to this law). Rangefinders aren't perfect and the smaller they are, the harder it is to detect the range accurately (inverse square law again). Lase…

Not trying to nitpick but I had trouble following some of your wording. What would the international incident be over if it happened during a fight? I get that blinding civilians by accident during a training exercise could blow up but blinding targets with a high powered laser doesn't seem that different from using flash grenades when storming a building. I was also unsure because you mentioned it happening during a fight and it seems like if you can already lock onto a target to fire a laser into their eyes it'd be more efficient to skip blinding them and just shoot or bombard them.
