A lot of spin there fella. Looks like the Rus propaganda machine is in overdrive.
The missile shown in the tweet you posted is an R37M (Axehead). It’s not new and had been used by Russia in Ukraine since last November.
It is a very dangerous beyond visual range missile and yes it has caused Ukraine a lot of problems. It’s usually deployed in the MIG-31 or SU-35 fighters.
The target acquisition radars can pick up Uke aircraft at ranges upto 300km, the missiles are then launched (fire and forget fashion).
In the early days the Ukes lost a lot of aircraft but the figures of 10-14 in a single engagement is outlandish and simply untrue as Ukraine barely has 4 aircraft in the air at any one time so I’d say those claims are bollox.
The Ukes have found a way however to spoof the missiles but it’s very dangerous.
When the R37 gets closer to its target its onboard active/passive seeker switches to active mode (at about 30km from target) this radar uses a technology called Doppler shift (don’t wanna get into it here) but the Uke pilots found that they can avoid the missile by using a technique called notching.
Effectively they invert, go into a dive, whilst pulling back hard on the stick. This manouvre can break the missiles active radar lock. Downside is their RWR receivers give them about 15 secs of warning to react and implement this manouvre also they burn a lot of fuel doing this so the overall impact is that their missions get disrupted, so the missile kinda does its job (call it a soft kill).
So in summary:
Nothing new here it’s not a new super weapon
Yes the R37M and it’s launch platforms present BIG problems for Ukraine
They have found ways to avoid being shot down by these missiles but it’s an uneven fight for sure
