*Looking at radar* "Eh, why is there a large bird flying at 600 mph?" *Hears explosion* "Damnit"
PRO tip: if you ever detect a bird flying at 600 mph in your radar, shot it down!
That's how the serbs detected f117 , the hardest part is locking on them but we have more computing powers that we were , so stealth basically useless
@@boiboiboi1419 Nope, he got hit by missile switched to line-of-sight guidance.
I think you might find that the radar might not display things as small as birds, or the radar display would just be cluttered. Whether they can distinguish between bird signals travelling at high speed is another thing. If stealth is useless, why are other countries building stealth aircraft as well. Longer wave length radars seem to have some effect in finding stealth aircraft, but these can not achieve a missile lock.
Degsie1975 why? For deterrence, only usa , china and russia building stealth aircraft, and the rest of the world aiming for super maneuverable craft like gripen , su35 , mirages
Why ? Because of wing man drones, wing man drones can be customized into many thing , anti stealth , anti bvr , anti jammers
We're going back to dog fighting
seeing the B-2 on radar:
guy 1: what that there?
guy 2: it's probably just a bird
guy 1: but it going 600 mph
guy 2: it's a big fast bird
probably the first intuition would be that it is a missile (?)
Guy 3: are you two kidding me?!? It just took out a bunker you but skulls!! Declare war!!!!
the soldiers are fast
*but big bird with bomb is faster*
It'd get filtered out
Giant falcon that's diving
It's got a cross-section of a bird but going 1000 km/h. Lol
Radar operator: sir this bird is moving at mach 1
Objects like birds are filtered out
"Damn that's a pretty fast bird."
Rcs of a bird is better than having the Rcs of a b 52
hella underated comment lol
Nah, Mach 1 is 1234 km/h... B-2 has a top speed of Mach 0.81 or 1010 km/h
My friends father was one of the core designers of this aircraft when he served in the air force. He still to this very day won't even tell his own son (my friend) a peep about it. I'm still amazed how ingenious him and his team were to create such a fine piece of engineering for its time.
I designed the atomic bomb but never tell anyone about it either.
It has the radar cross section of a large bird, travelling at 650mph.
Kalgoorlie10 exactly what I thought xd
You mean you've never seen a Jet-Powered bird before?
Get with the times, Sheesh...
Except for the fact that radars filter out small things such as birds
What about the pootis bird traveling at the speed of light.
Why filter out the birds just make it higher send-recieve timing and add a predictive trajectory computer. If it flies fast enough show it.

It's a "stealth" bomber. Get it?
There's something you missed, I actually consider kind of a big thing, the B-2 isn't invisible to ALL radars. Here's the thing: lots of SAM sites (very big ones such as S-400/ 500) consist of two kinds of radar systems, Low frequency radar (L-band, early warning radar, in use during WWII) and High frequency radar (X-band, also used on fighter jets). The L-band radars don't really care about the shape of an object, and in fact can detect the B-2 easily, even though the B-2 does have some L-band reducing design features, they only help a little, but there's a catch. L-band radars are not accurate enough to give targeting info to a missile (another downside to L-band is that they have to be huge and cumbersome) so this is where X-band radars come in. These type of radars are used to guide radar guided missile to their intended target, which is why fighter jets use them, but this part of the spectrum is where the B-2 is meant to be stealthy, so they can see the B-2 but can't shoot anything at it. X-band radars do consider the shape of the object a lot more significantly than L-band so the B-2's shape absorbs and deflects radar waves WAAAAAAY easier than it does with L-band radars. Otherwise fantastic video :3
Also the B-2 isn't invisible to X-band radars, it just needs to get closer to be detected, often times significantly.
Mr.Fluffybutt Gaming Low frequency radars can't guide SAM's in though
L band is vhf and is easily jammed....
Also the missile doesn't have l band vhf so it cant see the b2
This reduces chances of a successful intercept
ALSO no one wants to discuss us total spectrum dominance program.....

Thanks for the tutorial now I can make my own stealth aircraft!
The problem with stealth was hinted in the video - many ground radar systems can detect something the size of a bird, so when they see a bird moving at 500mph they know what it is!
Exactly.
The software also ignores anything under certain speeds.
Gummy Bugz Hahaha
Good radars will see a large bird (probably bigger than that) moving at 500 mph. Cheap soviet-era radars won't see anything. A great majority of Chinese/North Korea/Iraq militaries are made up of soviet-era technology. Any modern tools these militaries have are few and far between, and these few are legally bought or poorly copied from American defense contractors. I wouldn't be surprised if they suddenly stopped working in a war against the people who made them :P
Doesn't matter if they know that a tiny blip moving that fast is a stealth aircraft. What matters is when they can spot it, and if they can track it well enough to guide missiles in the timeframe that it's visible. Stealth aircraft have never been invisible to radar, but they have always been able to fly routes that would be dangerous to normal aircraft. Stealth tech doesn't need to eliminate the enemies ability to see it, just reduce it enough to fly through airspace it otherwise wouldn't be able to.

About the Ho 229, it really wasn't that stealthy. Due to the engines being imbedded into the fueselage, it's radar cross section was only 20% less than other aircraft of the time. It also suffered instability issues due to a lack of rudder, and had no radar absorbing materials. Stealth simply wasn't a priority for it. It likely only had the shape of a flying wing to meet the contract requirements, but not specifically for stealth.
You need huge RCS reductions to have a relevant impact. Having a 20% lower RCS is pretty much irrelevant.
While I was at RAF Fairford for the RIAT a B-2 flew over. It was so quiet!

While it's true that the Horten Ho-229 had many of the same *basic* design features and radar characteristics, many decades earlier than the B-2, it wasn't primarily designed for stealth. The Horten brothers simply knew how efficient and maneuverable the flying wing design was, and were pioneers in the their development.
+Alex Parker
The Hortens did not have any R.A.D.A.R. characteristics comparable to the B-2, analogically speaking. It wasn't stealth by title or capabilities. It was a lower R.C.S. aircraft compared to most other designs, but only because of its inherent construction and size. The DeHavilland Mosquito shared a similar reduction in R.C.S. because of its construction.
The Man who taught me radar in college was one of the radar specialists who worked to develop this plane. Fun fact, he was a member of the program, but it was strictly top secret so he couldn't tell anyone. Also, secretly, his wife was a member of the program. Neither had any idea the other was a member of the program, and they both lived double lives for many years. Now they look back at it and laugh. The guy is an expert on radar guided missiles and whatnot, and that's what he taught me in college.

You forgot one more thing I think you should have added, the creator of the whole company of Northrop (Jack Northrop) is the man who made the first fly wing prototype in the world, the N-9M was the first flying wing ever to fly, made in 1929, followed by the Horton Brother's Ho-229 world's first jet powered flying wing, and then back to Northrop, the XB-35 Piston engine bomber and then the YB-49 Jet powered flying wing, and then with the advent of fly by wire, the creation of the B-2 Spirit.

If it's TLDR, watch "Was the horten really stealthy".
The horten was never expected to be stealthy, and it wasn't by any means. It only had a 15% smaller signature than other jets of the time, it wasn't even made of any strong radar absorbing material.

When I was a teen I had a friend who's dad maintained the wheels and doors of B-2 Stealth Bombers. He said that he was told there are additional factors to it's ability to mitigate it's radar profile. Such as white paneling made of a material that reflects radar underneath the darker paneling back into the darker paneling so that waves don''t get a chance to bounce. He also said that radar projects upward and traces a cone. So if they know where the radar stations are they can fly low enough to pass through negative space in the area stations cover. Anecdotal at best I know. But it made sense to me on the surface of it at least.

"Captain we are receiving a radar signal."
"Duck down, Homie, duck down!!"
The Horten 229 was not designed to be a stealth aircraft. You can see directly into the engine which is a huge addition to RCS
people tend to think "oh it's the same shape so it has the same function"
That's up for debate. It was made with wood and glue infused carbon powder, both absorb radar. The thing flying wing profile does help with RCS, despite the engines being slightly exposed.
To top it off, Northrop used it when researching their designs.
Most of the internet heavily exaggerates many aspects of German WWII military tech - a lot of amateur fringe sites multiplying the errors & exaggerations. I looked up the Wiki on the Horton Ho 229 & it is very poor indeed. A far better source is the website for the Smithsonian National Air & Space museum - the people who actually had their hands on the real thing! If you are interested you need only search for: Smithsonian + Horton + "is it stealth?"
*Reimar Horton* learned his trade as a designer of pre-war gliders where wood construction was the norm. In the closing parts of WWII materials shortages was a serious problem for the Germans & it was natural to go to a steel frame covered in plywood. For Horton stealth was low on the list of design priorities whereas range & fuel economy was at the top. Thus the overall shape was dictated by the need for low drag to achieve the range required.
Also note that It wasn't until 1983 that Horten mentioned that he *PLANNED* to mix sawdust, charcoal & glue between the plies of the wood, but we know it was never actually implemented. The Wiki of course tells a different story - the wrong story. There is a strong likelihood [IMO] that Horton wasn't being entirely honest in '83 - especially as all the major airplane stealth concepts [including radar absorbent coatings] was a hot topic within military airplane design circles years before '83. Very tempting for him to promote himself as being even more visionary than he was - & yes he was visionary.
However the WWII Germans were probably the first to consciously incorporate anti-radar detection into their designs in any major way. *PERHAPS* ... For example it has been suggested that their prototype electric U-Boat had canted sides partly for this reason & also I have read [on sites I don't trust] that the standard U-Boat snorkel head was covered in a rubberised material late in the war for a short time to reduce radar reflection, but it wasn't a success due to salt water & inhospitable conditions quickly removing it. NB I haven't the time today today to check the statements in this para via reliable sources [which ain't Wiki :) ]

@@0trov_ 😂😂
@@0trov_ because it's not the same technology ?
Correction for anyone watching this who doesn’t know: The Horton Ho 229 was not a stealth bomber, nor the grandfather of the B-2. Northrop Grumman tested a version of the aircraft made entirely of wood, and it still showed up on radar, as well as there being no evidence for any carbon paint on the captured airframe. More importantly, Jack Northrop, founder of Northrop, loved the concept of flying wings, building both the XB-35 propeller driven design, and the YB-49 jet powered version. Neither went into production, but he was able to see the preliminary designs for the B-2 before he died.
Jeremy Clarkson: "Arent we meant to not be able to see that?"
National Geographic created a reproduction of Horton 229 and tested it for radar cross-section using the same frequencies that Brits used in WWII and it was not stealthly, the engine intakes are very reflective. But it was less visible and much faster than any other aircraft of that time meaning when Brits would be able to detect it, it would be way too late to intercept it.
Plus it was supposed to be insanely difficult to fly.
The only reason it was less visible is because it was mostly made of wood, which isn't the best microwaves reflecting material in the first place.
Are you british ?
I remember the progam. As I recall it did reduce detection range though not as a deliberate design factor.
Even the B-2 isn't completely stealth, the Ho-229 was a very advanced tech for its time...

Why is this video showing us nothing?
When i was young I asked my dad how it works, he told me basically that if you threw a ball at it it would never come straight back to you which makes sense actually
Very informative 👌🏼
The 229 was built mainly with the idea of reducing drag to increase the top speed and range, rather than with stealth in mind. Also there were a lot of more practical reasons why the odds were against the 229 affecting the war. These include engine reliability, weapon accuracy, production, and the distributed nature of the Luftwaffe after air superiority was established over western Europe by the allies.
Great point about the limited computational power requiring the F-117 to have all flat surfaces. If you look at the F-117 from straight on, you will notice the belly of the aircraft is not flat, but has a convex shape that is achieved by various faceted surfaces. Even the edges of the panels, canopy, and weapons bay have a faceted edge to reduce the chances that there is enough collective radar reflections in any given aspect.
Finally, note that stealth aircraft do not render radars blind, but rather they significantly reduce the effective range of a radar, and that can be countered by varying frequencies. Stealth drops down detection ranges such that "gaps" are created in an IADS coverage area, allowing the aircraft to move through the defenses and get closer to a target without the radars seeing anything long enough to track and engage the aircraft.
I agree but it can't just be "countered" by varying frequencies, because you're still working at a huge disadvantage. On the other hand you can find more optimal frequencies against the stealth aircraft.
You can thank the late Ben Rich of Lockheed Martin’s Skunk works facility for stealth technology.It was his team of engineers who made that technology possible in military applications.
Mr.Rich passed away in January of 1997.He was a ‘can do’ type of man.
I wrote a paper on Tacit Blue which was the origin for stealth plane design, before B2! Let me know if you want to read it
always interested in learning more! My email is in my about section or send it over to me on twitter!
The Tacit Blue was the origin for stealth.
Actually it wasnt, Northrop made a working flying wing before the 229 and because of Jack Northrops obsession with flying wings he kept pushing the design and his designs later inspired the B-2.
No rudders? Clever engineering to save the day! :D
First used exactly like that in the Ho-229. German engineering "exported" to the US.
very Northrop

I've wrote a research paper about the Operation Paperclip and it's soviet counterpart, the takeover of german machines and gadgets (since the Americans got all the scientists) during the early cold war. So yeah, i am pretty familiar with that topic. Of course, the B-2 is decades ahead of the Horton, since it's developed decades later, but the influence on modern rocket and plane/weapon development is undeniable, since the germans were years ahead, especially with their aeronautic designs.
*****
Yeah, guess many had influence in modern rocketry. It never was one person alone.

Well, there were quite some around at the same time like Max Valier. Then there was Hermann Oberth, Walther Hohmann (the important Hohmann-Transfer is named after him), Johannes Winkler, Kurt Heinrich Debus, Sergei Korolev, Konstantin Tsiolkovsky and of course Wernher von Braun. They all had a place, some theoretically, some by experimenting (like Goddard).
Many of them were Germans, organized in the "Society for Space Travel" were they build and tested rockets in the late 20ies and early 30ies. By 1933 the German military got interested and many moved and lived in Pennemünde, the testside for rockettech, where they developed numerous rockets and flying objects like the V2 Aggregat, the first artificial object that crossed the border to space.
Great video but just a little information about the Horten 229 is that is was never intended to be a stealth aircraft and when it was being planed out the material that made it was found out to have actually make it more radar visible
3:35 when you pause the video but you can still hear the sirens.
Awesome!
Geetings from Uruguay!
1:30 What if radar waves hit B-2's wing perpendicularly?
Imagine a radar station which direction from a flying B-2 is perpendicular to B-2's wing leading edge. More precisely, wing's leading edge angle is 35º, therefore an azimuth of 35º from B-2 to radar station would compromise plane's stealth?
Also, it's known that B-2 surfaces use "continuous curvature". I don't know if this suffices to avoid the before-mentioned situation.
The design is superb
About the Ho-229: It wasn't stealth, like at all. It's shape meant that It wouldn't be detected until it was somewhat closer than other German fighters, but stealth was never the intention and it's designers didn't say it was stealth until much later.
The Avro Vulcan had a similar effect, where it would sometimes disappear from radar because it's shape accidentally scattered radar from certain angles, and that wasn't a stealth plane either.
don't like the ho229 being described as 'stealthy', when clearly the comparison stops at the shape. The shape of the B-2 obviously contributes to the radar cross-section, but do we know if this was what the germans were thinking when building it?
He says in the video that they didn't understand those principles when they built it.
+Sean Dali he also implied that the ho229 is stealthy and could have changed the war because of that, while giving no evidence of the stealthiness apart from the pictures showing a flying wing.

That's not what he said.
+Sean Dali "we can only imagine the impact this plane would have had if it were ready before the wars' end" while showing pictures of a destroyed London.
+Sean Dali by the way I will not reply if you don't have a valuable contribution to the discussion anymore.
How does the influence of nazi designs, when Jack Northrop also came up with the idea in 1939, and the XP-56 Black Bullet.
Which lead to the XB-35 and YB-49. Northrop was a champion of flying wings.
10k subs lmao. Youre at 3.5mil now. Its funny to look at old videos that creators have made. You're killing it.
The Ho-229 wasn't designed as a stealth bomber/fighter. It was simply build as a flying-wing jet fighter. Its stealth capabilities were only a side-effect of its primarily wooden construction.
The Ho229 would have had the same impact as the Me262. It was too late for Germany.
It was simply a proof of concept. Not intended for combat.
Horton 229 was stealth cause of its material (wood). It wasnt on purpouse. Same with mosquito.
not true, the wing shape's reflection properties also redirected away radio waves to the left and right, making the wings essentially invisible to radar. it was the engines inlets that were the only thing that would have shown up on radar, which combined with its speed would have made it capable of bombing Britain and leaving before interception would have been possible. good thing it never flew offensively.
I have my doubts of this was intentional.
GabrielKirov maybe not but both sides would have been very quick to realise what was happening, the war wouldn't have lasted long if the 229 had made it to full production...
[1] GabrielKirov is correct in what he wrote - the Ho 229 was "stealth" [to a small extent] because of the partial wooden construction, but "stealth" was not the design goal. *Reimar Horton* learned his trade as a designer of pre-war gliders where wood construction was the norm. In the closing parts of WWII
materials shortages was a serious problem for the Germans & it was natural to go to a central steel frame covered in a plywood skin & an all-wooden wing with plywood skin. For Horton stealth
was low on the list of design priorities whereas range & fuel
economy was at the top. Thus the overall shape was dictated by the need for low drag to achieve the range required. Nothing at all to do with stealth
[2] You are incorrect about the *"wing shape's reflection properties [...] redirected away radio waves"* - nearly all of the wing was wooden & thus it didn't reflect radar at all. The reason for the smallish radar footprint was:
[a] lack of propellers - metallic prop discs are very, very 'bright' on radar due to their large diameter & vertical orientation
[b] the small amount of vertical radio reflective area because no tail assembly with vertical fin
[3] It is not known if the engine inlets were particularly prone to radar detection - the inlets were not tested for this property - only the nose cone was tested
[4] Although the wing skeleton is wooden & the skin is wooden ply the engines, inlets, & central body of the plane are metal - thus the plane does have a radar signature
I recommend that you go to the website for the *Smithsonian National Air & Space museum* - they are the people who actually had their hands on the real thing. If you are interested you need only search for: *Smithsonian + Horton + "is it stealth?"*
Something else to consider: It wasn't until 1983 that Horten mentioned that he PLANNED to mix sawdust, charcoal & glue between the plies of the wood for the purposes of radar 'stealth', but we know it was never actually implemented in any of the prototypes. The Wiki of course tells a different story regarding the Ho 229 - the wrong story. There is a strong likelihood [IMO] that Horton wasn't being entirely honest in '83 - especially as all the major airplane stealth concepts [including radar absorbent coatings] was a hot topic within military airplane design circles years before '83. Very tempting for him to promote himself as being even more visionary than he was - & yes he was visionary.
lol.. you are seriously overstating the effectiveness and reliability of radar.
That looks fabulous & amazing
We made history in our life time together and thanks for making history with US
Not as stealthy as the military try to make out. It makes for a good story though.
As well as getting potential enemies worried. (a little bit)
When you get that stealth bomber in mw2 in a care package since it wasn't worth a killstreak slot
The last great Cold War aircraft that went into operation before the wall fell, she was not used in Desert Storm, but the USSR, wasn't fully dissolved just yet. Jack Northrop's great gift to the world, the Flying Wing Bomber...
This video is really helpful. I tried searching the internet for the characteristics of the B2 for a project, but I couldn’t find good answers. Luckily, I came across this video. Thanks a lot!
imagine checking the radar and spotting a small dot going as fast as 700 mph
I'm laughing imagining a dot and then it just goes by the entire screen in a second
I've read that the Horten 229 only used the flying wing purely for it's flight characteristics, with the stealth being a false claim after the war. What do you guys know about this?
+Andrew Quinlan
Almost exactly correct. It was largely chosen at the time of their development given their smaller use of materials in that form, and possible flight surface control experimentation.
Ah. Thanks for correcting me.
Thank god you made video on stealth
"Sir, we got a large bird approaching at 700+ mph. What do we do?"
"Nothing lol"
Nazi horten 229 is just as incredible .
+Pogues Mahone its the truth, brainwashed western bais
***** nazi made it first
True, many smart things in aviation were invented by nazi engineers during WWII, if not they obliged others to invent them by fear of their power.
I wouldn't even say nazi's, the Germans in general are just great engineers and inventors.
The horten 229 never flew, nor did it ever have an engine, and the airbrake rudder system would have been awful.
More interestingly, if you took a photo of B2 in broad daylight, it looks like missing pixels indicating broken camera than a huge plane.
Like a shape baby
God the B2 is such a sexy plane!
yeah we saw the american stealth when a russian anti air rocket in yogoslavia dropped a nighthawk with no problem
StingyThe WhiteSupremacist The F117 was very primitive stealth wise, plus the F117's flew the same routes over and over again allowing the Serbians to set up to counter it
StingyThe WhiteSupremacist and it took the bomb doors jamming to even get a lock
it was shot down becuase it flew only a few miles from the radar, and had it been just a few miles to the side the radar would have a much more difficult time shotting it down
The problem is that if you have a radar sensitive enough to detect a large bird, and software that only shows pip moving above certain velocities, then you can very easily spot a stealth plane.
This is correct. When stealth planes were being designed and built in the late 70s/early 80s, computing power was very weak compared to what it is now. Since then radar technology and computer processing power has improved exponentially while the design of the "stealthy" aircraft has remained static. What was white noise showing up on radar is now a clearly defined image of an aircraft.
Neither matters with the B-1 Lancer, since it just flies below the radar at > Mach 1. Even if you do manage to spot it, it's statistically very unlikely that an intercept fighter could catch one and achieve a firing solution.
Kerbal AirForce No it can't. The B1 is only capable of 0.9 mach at sea level and barely above Mach 1 at altitude.
pacus123 Sure. If you accept the declassified top speed as absolute, and assume any targets are at or near sea level.
Kerbal AirForce Good point. Nonetheless I seriously doubt the B1 has a top speed of more than 50% of its declassified top speed.This would still put it sub Mach 2 in which case it would be cannon fodder for Mig 31s with their look down shoot down capability.
The Horten 229 was unintentionally stealth, they did not design it with stealth in mind. It just so happens that when you construct your plane out of wood, it gains a stealth ability. There was no secret stealth technology.
I honestly love this channel
Interesting - so the B2 still reflects all the radar signal, it just scatters it. Couldn't this be defeated by having a networked array of radar stations? If they sent out pulses at different times, they would receive scattered signals and you could triangulate the location of a stealth plane.
I think this might be done IRL
I heart that even stealth planes can be spottet fairly easy when you have a good radar system.
a F-117 stealth bomber even got shot down over serbia in 1999.
from this german side it seems like they used 3 slightly modified soviet P-12 radar stations, SAMs and some Mig-21
they used triangulation to get the plane spottet.
home.snafu.de/veith/Texte/Stealth.htm
(you can use google translate for a rough translation or search for yourself for info)
Sure but then you have to remember its now possibly 1mile away because it takes a minute to fully piece it together.
You could triangulate the location, but detection isn't tracking. This shouldn't be enough for a lock-on.
The F-117 has only been shot down, because its bomb bays were jammed. They were open, increasing their RCS. They have flown hundreds of sorties, every single night. Just one has been shot down. B2's have flown over Belgrade, not even 30 miles from the F-117 crash site. Yet, it wasn't picked up by their radars.
In theory yes - with a but.
Most radar arrays have T/R arrays Short for transmit/receive
They cycle between the 2 and cannot receive while transmitting
To do this you would need a Transmit array and multiple different sites running receive, they would need to be networked with a super computer which would compare multiple received signals to triangulate the reflection
this is feasible but not as cost effective, this is why it hasn't been used.
The Russians have made claims to be able to link radar sites to sync T/R Cycles to better detect stealth aircraft in the way you described but they haven proven that it is a working tech.
My dad used to help build the b-2 he worked under the cockpit area he got hired when he was 18 to go help build them back when they were still classified he's now 48 and still works for Northrop Grumman however he doesn't build planes anymore he stopped doing that a long time ago
Automatically, I highly respect your dad
I live in north Las vegas and I've seen a few of these flying over my home for a while, amazing how many people will never see this
You totally forgot or neglected that Jack Northrop had worked on flying wing designs his whole life. YB-35 and YB-49 are two great examples.
*When u look up seeing a large bird flying at 600 MPH and see it drop something*
*OH. BLYA-*
The Ho-229 is a fun plane on war thunder
loool perfect comment🤣😂✌
yeah as a meteor food
Irwin Möller YOU HAVE A HOLE IN YOUR LEFT WING!!
I just tried to flick the “fly” off my screen
Too bad it’s getting removed soon, because the V3 they have in game isn’t the V3 that was designed. Or at least a simple model rework
stealthy and badass, I've always liked this plane
for anyone saying “but it’s loud”, you don’t hear the sound untill after you are bombed dead
China: Write that down, write that down !!
Actually if the nazis finished that aircraft they wouldn't do much with it. In 1944 Germany was fated to defeat and london bombings with rockets were common, but didn't did much because the British were ready.
the british were in no way ready for the V2s. Or do you think they let German bombers turn parts of London and Coventry to dust for propaganda purposes?
Pfft, the German V-2 project was a bit of a sham. More people died in creating the bloody things than it ever killed, and is said to have cost 50%/more than the Manhattan Project itself.
British proposals to counter the V2s were done as early as 1944, and in the end they simply made a deception campaign about where the rockets were hitting and how much they did alike how they already did with German bombers. This because attempting to shoot it down with anti-aircraft guns would've actually done relatively more damage/casualties than if they simply had let it be.
In the end they simply bombed it like everything else of Germany's industries, and the Germans capitulated and gave up the equipment for study and implementations for such things as the first rockets into space and the like.
Think it's important to mention that although the f117 doesn't look as stealthy with its angular design, it's cross-section was dramatically smaller
Yugoslavia detected the B-2 Bomber with simple soviet technology. They also shot down the stealth F-117 with a Surface-to-Air missile. This is because the radars there were very sensitive microphones. So an engine that’s loud would come up on the radar.
When I was in kindergarten I used to draw the B-2 every time.
imagine a bird going at 1 mach and people would not give shit?
I think the radar works in a way, that it only makes bigger things apear on the radar.
I loved the night hawk shape it’s so COOL
Who don’t people keep these secret... this has great information for a country to figure out how spot them easier
Hex sonic Line rider Any advanced military already has a much higher understanding of this than what is shown in this video.
