Other side, if a B-2 going into russia then it can carry twnety of these jammers, dispersing them on the way like candy , blinding out the radars.
The only protection against this kind of jamming (or as matter of face agains any kind of jamming) is if you use multiple radar,overlapping each others.
Just remember that stealth Only Reduce the Range a plane is detected using Radio waves.
It will never be invisible. Even if it have alien technology ,that totally neutralize radars
it can be shot down.. because....
If you can see it with your eyes, you can shoot at it. and any combat planet always produce
a lot of heat. you will burn your hands if you touch the engine of a B2 after it lands. same way with cars. It cannot totally hide it. not even close.
What all this means ,is that B2 will have No Chance to enter in any part of Russia ,that Russia have air defenses ,not even if it is 100% stealth ,because will be shot down by Pantsirs that use Anti Heat sensor optics that can detect the heat of any stealth planes. heck.. even a manpad
will shot down a B2 ,that is guided by lazer. or regular anti armor machine gun ,if it fly close to terrain that is the most effective way to hide from radars. Even a kornet-EM missile that is can shot down an B-2. if it is flying under 10km altitude and a soldier see it comming to his way.
So this is the problem of all American simulations vs S-400. it totally ignores that S-400 never goes alone. it will have Pantsirs ,BUks and Tors defending it. and you might be able to jam
a missile but not a bullet. and a B-2 might be able to reduce its signal but not totally. All planes produce heat and Noise ,you cannot hide that either. So things are not as simple and to get a B-2 and start throwing jammers and decoys. There will be a LOT of many early defenses that
the B-2 will need to deal ,is a network that is connected. And as soon one soldier visually see a B-2 will call by radio of what he saw and it will be game over. Airforce will be sent to shut down
the B-2. This is just in the worse case a really bad scenario ,that B-2 manage to hide from radars totally ,is flying low and the InfraRed guided air defenses are broken that day.
Since more like the job for an Alqaeda suicide mission. Probably the most useless plane American have ..-> B-2. no idea where they plan to fly that.Because will be unable to hide at all. it will be detected ,even if Russian radars fails. it will not be invisible to human eyes or Infra red optics ,of Pantsirs ,and it will need to deal with Russian Airforce too. then we have Russia counter electronics and jamming and decoys ,that will turn obsolete the american B-2 missiles.
this is bombs designed in the 60s during the Korean War.
B-2 is mostly a visual strike Bomber and need to get very close to its target to hit it.
with Unguided bombs.
Much more dangerous for Russia than a B-2 will be an F-16 armed with tomahawks with nukes. Americans have thousands of F-16s and they can do a mass attack and launch hundreds of them if not thousands them at the same time. Reason why Russia will is closely watching
any NATO "EXercises" Because mass deployment of F-16s or F-15s or F-18s it is a threat for Russia ,is armed with nuclear armed cruise missiles. The cruise missiles are not hard to defeat.
but in a mass scale attack ,it can overwhelm any defense. the same is true for Russia .
Fortunately for Russia ,they have a good jamming system and can create major interference
in any guidance of cruise missiles ,so their precision will be horrendous. will miss a baseball stadium if not more. depending when is jammed .
Aside that Russia air defenses can also target missiles ,but a massive first strike attack
of F-16s armed with nukes will be a major serious danger for Russia. Because failing to intercept just one missile will be terrible. For sure knowing how Americans think and how much hate Russia. it will be a Suicide pilot bomber. that will directly lead the nuke.
and even more dangerous thing could be a civilian plane armed with nukes. or a container.
also long range artillery armed with small nukes too. But B-2 seems more like to fight Russian navy in water or coastal places like a submarine base because will have not a chance to penetrate Russia territory for more than a minute without being shot down. it will be detected farther from Russia coast .because of its heat signature and noise of its engine.
All things said , i dont think B-2 is useless or any other stealth plane , it have its place,
but i don't see the b-2 become undetected any farther than 1-2 minutes of fly inside
Russia. Probably B-2 will be more useful to attack Russia navy in deep waters or a hit and run attack on Russia coastal zones..
