EU industrial capabilities may also have issues, but they are (mostly) different ones than Russia faces.
After that the Russian "elite" units were elite in name only.
This was in hour 8 of the war and it's worth bearing in mind that this war could have gone very, very differently.
There were many russian helicopters successfully landing at Hostomel, the area saw heavy fighting for several days until it was under Ukrainian control.

Rumors of an Il-76 downed close to Vasylkiv did not prove to be true:
> Claims have been made that Ukrainian aircraft shot down two Russian Ilyushin Il-76 aircraft transporting assault troops.[33][124][34] However, The Guardian reports "no convincing public evidence has surfaced about the two downed planes, or about a drop of paratroopers in Vasylkiv".[125]

Whatever shit tier RU MIC/performance has been, it has manage to consistently defeat or mitigate what US+EU has thrown against her. Which includes highend gear like PAC3 MSE. Meanwhile half the reason RU had a hard time was due to facing UKR's abundant legacy USSR systems. At this point it's not unreasonable to dismiss everything in EU arsenal as wunderwaffe tier especially without US support. Including F35... which even if US doesn't restrict usage against EU-RU scenario, could still be borderline paperweight without US tier ISR.
People also forget NATO fought a much shitter/temu RU in Yugoslavia where NATO threw everything at even more legacy soviet systems. All of the awacs, prowlers, F117 barely chiped away at 20% of Yugoslav anti air, something like 700 harms were fired and destroyed less than handful of SA6 batteries. Hard to argue EU part of NATO has better military capability than 20 years ago.
IMO there's a strong chance US would heavily restrict/limit F35 operations against RU. Because one shot down F35 by S400 let alone anything shittier completely evaporates narrative around 5th gen (and what that entails for IndoPac). They'd rather see RU hit F35s in hangers with standoff munitions because at least they can point to JP and SKR and say, see, you need to build harden air shelters.
Patriot works in Ukraine, they even got a few Khinzal. But of course any air defense is limited by available ammo and you need enough of the right kind of air defense in the right places for this to work well. The Ukraine is really limited by the number of available systems and ammunition. And for something like the Shahed drones you need other ways to defend yourself to avoid exhausting your precious ammunition for advanced air defense systems.
Russia also was shown to be nearly unable to intercept Storm Shadow/SCALP EG at the beginning. So the somewhat aging European cruise missiles were able to easily penetrate current Russian air defenses.
>patriot works
With US ISR (i.e. AWACs) providing early warning, IIRC correctly UKR was salvoing full patriot battery to intercept single kinzhal/zircon tier hypersonics, i.e. entire supply of EU patriot launcher can be overwhelmed by handful of hypersonics.
>storm shadow
Similarly UKR could sneak cruise missiles through RU IADs is because US info share helped plan missions/routes to circumvent RU defenses. Competent (not even super modern) air defense has like almost 100% interception on subsonic targets like cruise missiles, provided the are detected.
The TLDR is hard to say how EU hardware will perform without US force multiplier tier ISR. Which will effect everything from finding targets to hit, hitting targets, and avoid getting hit even with same/better hardware. Which again, is not to say EU is bad... but EU very unlikely to be US level great.
Most likely because they did not have the specs or complete specs for them and how they looked like on radar. There was an article somewhere that I can't find right now where something like this was said: Once a new weapon system is employed against RU or by RU against UA, it takes about two weeks to create countermeasures for it.
We are seeing Ukrainians regularly hitting russian redars and air defence. Whatever nato wasn't able to do in hte 90s the Ukrainians are fully capable of doing today, because they are doing it. And with lots of european help. So this is just outdated speculation you're doing.
EU part of NATO has improved ISR (helios, sarlupe, copernicus etc) but nothing rivalling US tactical and strategic capabilities, i.e. as far as I know, there's no EU system that provides all weather real time targetting.
Likewise the reason why Russia couldn't steamroll Ukraine swiftly is because Ukraine anti air is very formidable (using Soviet hardware no less). That is why it is wrong to simply assume Russia is weak.
russia is weaker than they have been since 1991, possibly 1950.
There is a reason they are now delivering ammo using mules and actually attempting old school cavalry charges on horseback.
And it it's not because donkeys are better than the armoured, tracked towing tractors or because actual horses are better than tanks.
Israel's F-35 have being going in and out of Iran's airspace with impunity, so no, I don't think that is going to be an issue.
