The FriedrichFiles - Suchoi Su 27 family


Which Su-27 is this? Itīs rather not the Su-34, Su-27IB, Su-27M, Su-27SK, but maybe the Su-30 or Su-27KUB?
Su-27IB and Su-34 look different
Who can tell me the truth about the Suchoi Su 27IB and the Su 34?

Here are some theories...

1a) Su-27IB: allweather/night ground attack, cancelled in 1991 in favor of the Su-34
8000 or 8200 kg weapon load; 1x 30 mm gun
1b) Su-34: allweather attack aircraft, developped from the Su-27IB (p.e. nose redesigned)
8000 or 8200 kg weapon load; 1x 30 mm gun
first flight of a production aircraft: 12/1993

2) Others say, that the Su-27IB was only another designation of the Su-34, some say both were used simultaneously, some say Su-27IB was used first and later it was called Su-34, some say Su-27IB was used by the manufacturer and Su-34 by the Russian airforce or otherway round. This aircraft was ready for delivery or in production sinve 1996.

Here are some pictures... they indicate there are two versions existing: the Su-27IB and the Su-34:
