>>4568Pics 1 & 2 are MiG-31s, pic 3 is a MiG-25. A sexeh beast indeed.
The MiG-25 is pretty fucking awesome. It can reach about Mach 3 under the right conditions, it has an extremely powerful radar that is also resilient to ECM and EMPs, and it does all of that by using engines from a cancelled cruise missile project, vacuum tubes, and being made out of steel.
The MiG-31 modernizes the whole thing with upgraded electronics and perhaps better aerodynamics, although it's a little bit slower (but still really fast).
On a related note, the Mikoyan Ye-150/152 (picrel) used the same engine as the MiG-25 and was also meant to be an interceptor.
