I’m struggling with what’s the role of hypersonics if air defense penetration is already covered by the b2.
Something that has been explained to you repeatedly with examples. If you’re still not capable of understanding what’s been explained to you, then it’s safe to say there’s not much point trying further.
The US has tested stealth bombers against s300, because they got some.
S300 is an old system. US has never used bombers against modern air defence, and I’ve already provided you with sources showing that modern radar systems can detect them. Naturally, you ignored that since it doesn’t fit with your narrative. All you’ve done here is just regurgitate the same points that have been addressed repeatedly, while ignoring the answers.
When has a hypersonic missile (not the ballistic missiles strapped to planes Russia uses) penetrated heavily defended airspace? (There may be some, I know Russia definitely claims it, but I haven’t seen good proof yet)
