They are still a few years from production of the systems needed to see and shoot stealth but the days are numbered for stealth.
We have been able to see stealth since at least 1985 that I know of. The Russians picked up on it about 1988 but with the demise of the USSR they stepped back from development until they got back on their financial feet about 8 years ago. They have moved forward with anti-stealth technology and are on the verge of releasing multiple systems, air, sea, and land, that can see and shoot stealth.
Stealth is good stuff and should be used to defeat manpads and other non-sophisticated missiles, but it cannot defeat sophisticated imaging systems. It does reduce typical CW radar signatures and is useful for penetrating Russian airspace for bomb delivery, but gravity bombs are rather stupid when we have ICBM/SLBM delivery capabilities that cost less per warhead and are nearly 100% effective. Those warheads also employ stealth and other countermeasures like decoys and chaff, which makes them far better than aircraft at delivering nuclear warheads.

Last time I’ve check manpad missiles aren’t radar-guided. F-35 is actually a better targets for most manpads than helicopter, and we all know manpads are pretty much effective against helicopters.
