I dont think the Su-37 was a real production aircraft. It evolved into the SU-47, but what I think your thinking about is the SU-35. But I may be wrong
In game:
This time it was real, this time I was out for blood. The fucking allied air force had started bombing our eastern cities. Hoping to find some secret fucking base that doesn't exist. Not giving a rats ass if there's civilians there or not.
This time there's blood, this time, there's me.
I saw the formation below, an F-22 escort and five B-52's. They were going to level a coastal town. There wasnt even a base there!
I banked down, to the right. I turned and flared my engines and dived right on top of them. I locked two of them and fired. My Berkut dove below them racing at more than twice the speed of sound. I was a thousand feet below them when I saw the ripped off wings from two of the bombers and their torn and dying hull racing to their death. I was racing with them, it just wasn't my turn yet. I felt 20 milli bullets pound my hull, the F-22 had dove off from the formation to chase my ass down.
I pulled up and the wings caught the air. Like a dancer in a storm, I was an artist. The wings pulled up and I was no longer racing, I was fighting. My nose was up and I had turned around in less than a thousand feet. And a stunned F-22 did not know what to do, he did not know what was going on till the explosive rounds ripped his wing off. I saw the parachute and called it in.
I gained altitude and saw the three other B-52 bastards running off. I ripped them apart.
