The Americans (using local traitors and useful idiots) destroyed a Russian AWACS plane (Beriev A-50). It is not reported, but I would venture a guess that the plane destroyed was the A-50U variant, modernized with state-of-the-art electronics.

This is the second large mobile radar the Americans destroyed. The first one was on the cruiser “Moskva”, and I always suspected that they used diversion in order to blow up the ammunition on the ship. The strategic intersection of those two is the ability to monitor the Western airspace with high resolution. The reduction in nearby radar coverage is likely to degrade Russian early-warning abilities related to American stealth aircraft, which means a delay in response to an American strike, possibly using stealth aircraft to launch nuclear-tipped cruise missiles. This is the attack of the kind Americans would answer with a nuclear strike, were it performed against their strategic assets, especially since Russia seems to have only seven or nine of those modernized flying radars, depending on various reports.

This took place because Russia encouraged such attacks by not responding to the first few, and if they continue playing this game, it will get worse.

Edit: There were no confirmations of this, and Intel Slava Z channel claims it’s all fake news.

Edit2: Intel Slava Z reports that “In Belarus, a terrorist of the Ukrainian special services and his accomplices were detained, who are involved in an attempt to sabotage an A-50 aircraft at the Machulishchi airfield, – said President of Belarus Alexander Lukashenko”, so I would say that something obviously happened; either 1) an attack was attempted and failed, or 2) it succeeded but the consequences were of such strategic importance that the Russians preferred to just swallow it, fly in another plane, take pictures and pretend nothing happened, rather than escallate this to the level appropriate for such a transgression.

Edit3: “The aircraft was transferred to Russian for maintenance and another Russian A-50 should be sent to Belarus.” (Southfront)
Yeah, second interpretation from edit2 confirmed.
