| Variants | |||
| T10 ("Flanker-A") | Initial prototype configuration. | ||
| T10S | Improved prototype configuration, more similar to production spec. | ||
| 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-27S (Su-27 / "Flanker-B") | Initial production single-seater with improved AL-31F engine. The "T10P". | ||
| 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. | ||
| Su-27UB ("Flanker-C") | Initial production two-seat operational conversion trainer. | ||
| Su-27SK | Export Su-27S single-seater. Exported to China in 1992-1996 and developed into Shenyang J-11. | ||
| Su-27UBK | Export Su-27UB two-seater. | ||
| Su-27K (Su-33 / "Flanker-D") | Carrier-based single-seater with folding wings, high-lift devices, and arresting gear, built in small numbers. They followed the "T10K" prototypes and demonstrators. | ||
| Su-27M (Su-35/Su-37, Flanker-E/F) | Improved demonstrators for an advanced single-seat multi-role Su-27S derivative. These also included a two-seat "Su-35UB" demonstrator. | ||
| Su-27PU (Su-30) | Two-seat version of the Su-27P interceptor, designed to support with tactical data other single-seat Su-27P, MiG-31 and other interceptor aircraft in PVO service.

| Su-27PD | Single-seat demonstrator with improvements such as inflight refuelling probe. | ||
| Su-30M / Su-30MK | Next-generation multi-role two-seater. A few Su-30Ms were built for Russian evaluation in the mid-1990s, though little came of the effort. The Su-30MK export variant was embodied as a series of two demonstrators of different levels of capability. Versions include Su-30MKA for Algeria, Su-30MKI for India, Su-30MKK for the People's Republic of China, and Su-30MKM for Malaysia. | ||
| Shenyang J-11 | Chinese version of Su-27SK. | ||
| Su-27SM (Flanker-B Mod. 1) | Mid-life upgraded Russian Su-27S, featuring technology evaluated in the Su-27M demonstrators. | ||

| Su-27UBM | Comparable upgraded Su-27UB two-seater. | ||
| Su-27SM2 | 4+ gen block upgrade for Russian Su-27, featuring some technology of the Su-35BM; it includes Irbis-E radar, and upgraded engines and avionics. | ||
