Variants

T10 ("Flanker-A") Initial prototype configuration.

P-42 Special version built to beat climb time records. The aircraft had all armament, radar and paint removed, which reduced weight to 14,100 kg. It also had improved engines. Similar to the US F-15 Streak Eagle project. Between 1986–1988, it established and took several climb records from the Streak Eagle. Several of these records (such as time to climb to 3000m, 6000m, 9000m, 12000m) still stands current as of 2019.

Su-27 Pre-production series built in small numbers with AL-31 engine.

Su-27P (Su-27 / "Flanker-B") Standard version but without air-to-ground weapons control system and wiring and assigned to Soviet Air Defence Forces units. Often designated Su-27 without -P.
