Riccardo No Way? It could fly that high? It looks so little and insignificant. TELL ME MORE!

@@patrickyoung2117 The Su-9 is a big aircraft. Ultil Su-15's and Mig-25's entry into service, the Su-9/11 were the fastest and highest altitude aircrafts of the USSR. In the web you can find anything. Used also against Powers on 1st may 1960.

Couldn't they only do that by accelerating to near-max speed and pulling up into a zoom climb to get above the U-2?

@@1930Granada The Su-9 had a practical ceiling at above 20.000 m, but it is a high speed interceptor, with no prolonged combat air patrol, no in flight refueling. This means that the majority of interceptions were with a scramble from the ground, ground guidance and zoom climb. This limits the range with the target's altitude.

Im just reading a book on the subject. The SU 9 and 11 could in fact intercept the U2, but in a very narrow intercept parameters. No, it didnt flight as high as the US but their missiles could (some specially prepared aircraft could). They needed to do a zoom climb and nearly Mach 2 with close and competent ground control guidance. The first mission in Ubezkistan in fact failed. But once the American realized they could, they had to stop the overflights. The Gary Powers intercept also failed because the airplane sent againt it lacked missiles, it was just comming of a ferry flight. So a S 75 took his plane.

Hey Danke Abo hast du schon lange ^^

High performance early jets were a bitch to handle, plus the Russian weather....

Mig 21 is a fighter, SU 9 was a interceptor, it was heavier and could fly highter but was not agile.

@@ricardosoto5770 Su-9 also only had missiles. Mig-21 was intended as an interceptor as well, and had missile-only all weather interceptors variants such as the Mig-21PF. Eventually they equipped it with a cannon pod and missiles on the wings, but for them in the late 50s to early 60s, any interceptor design was desired for production. Hence Su-9/11, the early Mig-21, Tu-128, and the would be MiG Ye-152 all coincided. As did the Mig 23 and Su-15.

They used the same TSAGI (soviet russian NASA) research but often the Sukhoi were the heavy fighters and the Mig the light ones.

MIG developed a twin-engine version.....which might be the Chinese clone J-8
