gf0012 is quite correct. An impressive aircraft capable of impressive maneuvers and nobody can argue with that. Unfortunately the Su 37 is a day late and a dollar short when comparing it to the 4th generation jet fighters the west will be putting on the ramp in the next couple of years.
Once the Su 37 pulls up and begins it's rotation it will do things that you just don't do in an aerial engagement and live to talk about it.
1. You present the biggest possible target the aircraft can display to a radar guided weapon.
2. The aircraft essentially stops moving in all axis relative to it's position in space which will then provide an opponent with a nearly zero deflection firing solution (a fighter pilots dream come true) regardless of the opposition position of both aircraft.
3. Maneuvering is reduced to nearly zero. The aircraft is still capable of controled flight but is unable to vacate the space it is in on the grand scale neccesary to thwart an incoming missile threat. Again missile evasion depends entirely on being able to make the largest possible angle of deflection which in this case isn't happening. In other words, you need to put the biggest amount of space between you and where you were when the threat aircraft fired it's missile, increasing the angle of interception is as always optimal.
So ultimately the wonderful Su will be a serious predator on a battlefield populated with older generation aircraft, but it will be behind the power curve fighting a wealthier industrialized nation with state of the art aircraft. I still like em though, and would LOVE to have one in my hanger
