What's with the US air force attracting all the lunatics? Though I suppose there is something to be said about the popular rhetoric even ordinary people like to throw around these days, if the tweet below is any indication. Jingoistic chest thumping seems to be in vogue, now.
What is really retarded is that they put a picture of the MiG-31 as an example of what they call a paper tiger and "cloned technology".
The MiG-31 was the first fighter in the world with a phased array radar to enter service i.e. Zaslon. It was the first Soviet aircraft with good look down/shoot down capability meant to be able to distinguish relatively low signature cruise missiles traveling at low altitudes in the middle of the clutter and intercept them. The MiG-31 has a digital datalink where it can share its radar picture and targeting with other aircraft. It is basically an airborne node of the Soviet GCI air defense network. A force multiplier which could enable other aircraft like the Su-27 and MiG-29 to be guided to targets even if they were outside the range of the ground based network. At that time
no Western fighter aircraft had proper datalink capability of such type. Then there is the R-33 missile. A long range, semi active guided missile, which in the MiG-31 is also capable of engaging multiple targets simultaneously. The MiG-31 basically corrected all the flaws in the MiG-25 and was leading edge when it came out.
With electronics modernizations of the aircraft and missile, as the MiG-31BM, the aircraft did the longest range shoot down
ever of an aircraft in this conflict with Ukraine like some four decades after it originally came out into service.
Also, unlike with the MiG-25, the speed in the MiG-31 was limited to Mach 2.8 not because of the engines, but because the canopy would melt and had to be replaced. In the MiG-31BM they changed the canopy material. And it is claimed this increase the max rated operational speed of the aircraft. Likely to actual Mach 3.
These guys were probably intending to mock the MiG-25 but put a picture of the MiG-31 by mistake. It is true that the MiG-25 was developed in a crash program with components they had around. Like the radar on the Tu-128, and an engine taken out of a drone aircraft. But it was still capable, with the huge R-40 air to air missile, of shooting down US aircraft in Iraq over two decades after it entered service.
