"The A-50 fleet has been rendered mostly ineffective at this point. The Russians have lost enough of them that they can't do the job full time anymore."
How so? Is one A-50 by itself not capable of performing its functions as a control center and early warning detector? I do not believe these are team players, in that sense of the word.
What I DO believe is that, even if they haven't emasculated the jets, the Ukrainians at least have done so to their would-be crews. And this is a crucial point regarding any future conflicts from Stettin in the Baltic to Trieste in the Adria.... oops, got a bit carried away there...from Svalbard in the Barents to Sevasotpol in the you-know-where, NATO will be at least as capable as have become the Ukrainians in turning A-50s into plowshares.
