How Does Stealth Technology Work?

Stealth aircraft can give pilots a huge advantage over opponents by being difficult to detect on radar - but how is it possible to keep something so large and powerful hidden from the eyes of the adversary?

As an avid aviation, technology, and military junkie I'm very impressed with the quality of information in this video. Given that I thought you might be speaking out of your area of expertise I was not expecting this video to be so full of good information. Especially given how much disinformation is out there on Stealth technology these days.

I commend you, even I learned something new from this.

So it's not a good idea to put RGB on my stealth bomber?

[nikhilrajbhar]

Paint normally known as RAM (radar absorbent material)

Fun fact about flight stability. The Eurofighter is purposefully built to fly as unstable as possible. In this case, stealth is not the reason, instead it is the fact that an aircraft that flies unstable is physically easier to get off-course, making it more maneuverable. This makes flying it incredibly difficult, virtually impossible, right?
No, it doesn't, because it has a fly-by-wire system that is constantly making microadjustments to keep the plane steady, executing the pilot's commands precisely and quickly.

If you put red stripes on the Nighthawk, it will look like a gaming laptop.

They just get rid of the RGB saved you 6min your life

Everyone in the comments talking about the F-117 lost in Serbia in 1999, let me explain this to you. The F-117 did not get shot down because of it "lack of stealth" originally. The main reasons for why this nighthawk was shot down were: bomb bay doors open (reducing its stealth capability and increasing its RCS), the F-117 had been flying the same route continuously and the serbian forces knew roughly where to focus their radar search, and the implementation of LFR (low frequency radar) which is effecive at detecting earlier generation stealth aircraft such as the F-117 and SR-71, but has very big issues with background noise, needs to know exactly where to look, is not very good at guiding missiles onto a target and requires a very very large antenna array. This is why the F-117 Nighthawk was shot down. Not because its stealth didn't work, but rather a combination of unfortunate factors which in the end resulted in the first and only loss of a stealth aircraft to date.

Without a doubt, one of the best TechQuickie videos, Linus. Many thanks - this was great!

[Cyba_IT_NZ]

These tips are gonna be great for my next stealth build

[curtiswaters]

Love this video. Please do more tech videos about military hardware, or even just non-computer related things.

This is really cool. I kinda knew about the flat shapes but not the paint.

And nice job on the graphics if you did them in house. Their no thought cafe graphics but simple and shows us how it visually is happening.

[mactwentytwentyfour]

From someone who personally worked with 3 of these aircraft mentioned: Linus did a good job on the basics of stealth technology. Good job👌
For future reference: these paints can cost up to $5000/ GALLON. Yes I said Gallon. GG. And technology itself using avionics can help reduce radar return. The F22 is a great example of this.

[krystaldragons]

Does anyone else wish linus would go into more detail? Don't get me wrong I love the vids. I just wish there were atleast more parts relating to topics like this one( how does stealth work part 1 of 4).

[pdroa]

this has to be one of the best videos you ever put out





after the anti rgb build

[joshdisciple]

I enjoy the fact that when Linus mentions Infantry the picture shown is US Marines on the Firing Line

[LosSerpent]

but the real question is.... are stealth jets gonna have RGB???

[BigJohnFlop]

It was only a couple minutes later that Linus from LTT was found dead

Mostly what you are talking about is Passive radar deflection methods, years ago,   Illegal in both the US and Canada you could order a kit for your car that deployed a field around the car through a front plate and a rear plate, more complex kits had side pieces for your car. They produced a M.A.S.C. Unit that essentially that actively dispersed Laser and Radar signals that either registered as nothing on a laser or showed "ERR" on the radar gun. basically its the same idea as reducing sound waves like active noise cancelling sending waves that cancel each other out of the opposite frequency.

Depend on the technology, materials and minds behind the creation.
