I remember hearing we had trouble with the MiGs when they were put into service, but I forgot what jet we fielded that was able to take them on.
Which time? In Korea, the F-80 Shooting Star was no match for the MiG-15, so we brough in the F-86 Sabre.
In Vietnam, The MiG-21 gave the F-4 a hard time, leading to the F-14.
Simultaneously, the MiG-25 scared the pants off the West, leading to the F-15.
Also, remember that the Russians still have two versions of their military equipment. Standard is for themselves, and the "monkey model" for export. The term "monkey model" is for who they believe will be running it.
What migs and what war are you talking about? During Korea, we countered the Mig15 with the Sabre Jet(F86), and it had a 10 to 1 kill ratio over the Mig15. During Vietnam we screwed up because we used planes that didn’t have guns, and they couldn’t compete with the obsolete Mig17s the North Vietnamese had, but we fixed that and we developed the F15 eagle. This plane has never been shot down in combat and knocked the crap out of Migs during the first gulf war. It is still unbeatable and now we have the F22 Raptor if Bozo doesn’t decide we don’t need aircraft to fight a war, the way Clinton did when he decided to destroy a whole shit load of B52s.
