Su-30 (Su-27P) is a two-seat long-range intercept fighter that first flew in December 1989, and that entered service with the Russian air forces in 1992. Largely based on the Su-27UB two-seat trainer, it has a new radiolocation system which can transmit the positions of 10 targets to four other fighters at the same time. The Su-30 is made in Irkutsk.
