Sukhoi Su-30: Russia’s Multirole Fighter Explained
The Sukhoi Su-30, a formidable multirole fighter aircraft, stands as a testament to Russian aerospace engineering. Originally developed as an advanced variant of the Su-27, the Su-30 evolved from the Su-27UB combat trainer and was initially designated as the Su-27PU. Over time, it was enhanced with advanced avionics, extended combat range, and ground attack capabilities—making it a true multirole platform. The jet took its maiden flight in 1986, entered production in 1992, and officially adopted the Su-30 designation in 1996. In NATO terminology, it is referred to as Flanker-C.

Design and Capabilities of the Su-30
At its core, the Su-30 retains the robust aerodynamic layout of the Su-27, including the same airframe structure, twin-engine configuration, and high agility. Modern iterations introduce advanced systems such as phased-array radar, canards, and thrust-vectoring engines, enhancing performance, especially in air superiority and dogfighting roles.
The fighter is equipped with a 30mm GSh-301 internal cannon with 150 rounds and up to 12 external hardpoints depending on the variant. It can carry an impressive payload of up to 8,000 kg, including air-to-air missiles, precision-guided bombs, anti-ship missiles, and unguided munitions. These features position the Su-30 as a strategic equivalent to the American F-15E Strike Eagle in terms of versatility and mission profile.
Powerplant and Range: Endurance Meets Speed
Powered by twin Saturn AL-31F afterburning turbofan engines, the Su-30 delivers exceptional thrust and maneuverability. Its operational range spans 3,000 km on internal fuel alone. Thanks to an onboard aerial refueling probe, the combat radius can be extended to 5,200 km, allowing for 10-hour missions without landing—a critical advantage for strategic missions and extended patrols.
Operational Use: Russian and Global Deployments
The Russian Air Force remains a primary operator of the Su-30, though it now focuses more heavily on the newer Su-30SM variant, which features modernized avionics, advanced radar systems, enhanced weapons compatibility, and improved pilot survivability through upgraded ejection seats.
Beyond Russia, the Su-30 has been widely exported. The aircraft is in service with air forces across India, China, Algeria, Malaysia, Venezuela, Vietnam, Kazakhstan, Indonesia, Angola, Armenia, and Uganda. Each export version is uniquely tailored to meet the customer nation's operational needs.
Key Su-30 Variants and Global Operators
Su-30K
