If you design a super stealth bomber ,using Plasma tactics ,and this bomber can fly in the mesosphere at altitudes of navigational satellites , from 30k to 50km altitude.
There are no satellites between 30km and 50km altitude... the atmosphere is thin at that altitude but still thick enough to slow a satellite down and make it fall back to earth.
The lowest orbit a satellite could operate at would be well over 100km altitude... probably just under 200km altitude or so.
Then Russia will have a bomber that will be near impossible to stop with traditional NATO air defenses or high altitude missiles.
The obvious problem there is that while Russia spends money developing such a bomber the west can simply spend some money making something to shoot down bombers of that speed and that altitude.
Such bombers will have the power to fly above NATO aircraft carrier groups and take pictures from above of their entire formation and without being detected but even if were detected , they will have no way to stop them ,because will fly in a zone their Aegis defenses can't intercept anything. and neither their combat planes will be able to intercept ,because will fly too high and too fast and will not be visible in their radars if have plasma stealth.
Or they could take pictures with all the new military satellites they are putting up... and of course they could simply fly a few converted civilian airliners fitted with cameras... taking photos is not an act of war and could not be used as justification for shooting down aircraft in international air space.
So such a plasma stealth bomber will force United States to sign a peace deal with Russia and remove the ABM shield in Europe and even remove their military bases from all eastern Europe and any place near Russian borders .
How Naive...
Even if a fully developed mach 15 plasma stealth bomber could be created and put directly into service the west would not remove anything. This aggression would lead to them developing missiles and air borne lasers to shoot such bombers down... which of course they will need to base in Japan and Europe...
If you control the space above any warship of plane ,then you will have a huge advantage of the capability to fight and without the enemy have a way to stop you or fight back.
An ABM system can shoot down ICBMs and SLBMs flying at very high speeds (7km/s or so)... what makes you think they would not adapt it to also shoot down bombers?
Their SM-3 missiles on their AEGIS class cruisers are part of their ABM system... what makes you think they wont adapt them to shoot down hypersonic bombers?
Plasma stealth bombers could simply be targeted with IIR guided missiles...
Vann... don't you get it?
For every measure there is a counter measure and for every countermeasure there is a counter counter measure... there is no winner for long.
Remember for ages all tanks were dead because ATGMs were so powerful... now it seems armour is winning... the same can be said for aircraft... for ages aircraft were dead because of MANPADS and other SAM systems... new electronic self defence systems suggest that might not be so certain.... it is a continuous war where no one wins for long.
