Europe’s Longest Ranged Fighters Enter Service in the Belarusian Air Force

The Belarusian Defence Ministry has confirmed the delivery of a new batch of Su-30SM2 fighter aircraft from Russia to equip the Belarusian Air Force, following the delivery of a prior batch in December 2025. The arrival of the aircraft was confirmed by the deputy commander of the Air Force and Air Defence Forces and chief of aviation, Colonel Aleksandr Belyaev, who observed: “The main task of our aviators is the protection of the air borders of our country. They stand on the first line of defence.” “The arrival of new aviation equipment is always a celebration for aviators. Flying a fighter that has just left the factory is honourable and pleasant, but it also obliges a lot,” he added.

Colonel Belyaev elaborated that the responsibility felt by personnel handling new fighters is exceptionally high. “The sense of responsibility that aviation personnel experience when servicing such aviation equipment simply goes off the scale,” he said, adding: “We have no right to let down our people and our country. Therefore, we will do everything to ensure that our beloved Motherland remains peaceful and prosperous.” The Su-30 is currently one of four fighter types in production in Russia alongside the Su-34 strike fighter, Su-35 air superiority fighter, and Su-57 fifth generation fighter, and is one of multiple high value Russian weapons systems that has recently been procured alongside Mi-35 attack helicopters, S-400 long range air defence systems, and Oreshnik intermediate range and Iskander-M short range ballistic missile systems.

The number of Su-30 fighters in Belarusian service remains uncertain, and while reports would indicate a fleet of approximately 20 fighters, it remains possible that the Su-30SM2 fighters delivered are simply Su-30SM fighters formerly in Belarusian service which have been returned to the country after modernisation to the Su-30SM2 standard. Only one contract for Su-30 fighters is confirmed to have been signed, namely a $600 million order for 12 of the aircraft, for an average price of $50 million each. The Su-30 has provided a revolutionary improvement to the Belarusian fighter fleet, with the country previously having relied solely on obsolete Soviet-built MiG-29 fighters, which although cutting edge when introduced into service in the early 1980s, had a very limited air-to-air combat capability, and a negligible ground attack capability, by the standards of the 2020s. 

The Su-30SM is by far the longest ranged fighter type fielded by a European state, while its radar is also by far the largest at approximately triple the size of that of NATO’s primary fighter the F-35. Previously the longest ranged fighters deployed by a European air force were the Soviet Su-27 air superiority fighters that were inherited by Ukraine and Belarus, although the Belarusian Air Force retired the fighters from service in the early 2010s due to their high operational costs. Ukraine failed to significantly modernise them and allowed training standards to fall considerably, before the fleet was largely destroyed by Russian forces during four years of hostilities from 2022. The Su-30SM represents a heavily enhanced derivative of the Su-27 design with ‘4+ generation’ avionics and a high composite airframe. Despite being slightly heavier, the aircraft’s maintenance requirements and operational costs are considerably lower due to a range of design improvements made to the airframe. 

Improving on the capabilities of the Su-30SM, the Su-30SM2 integrates the AL-41F-1S engine which was developed to power the Su-35 air superiority fighter, and has a fuel efficiency level and thrust/weight ratio more comparable to early fifth generation engines such as the American F119 powering the F-22 fighter. The engines provide the Su-30SM2 with an even greater range, as well as by far the highest levels of manoeuvrability due to their high thrust and three dimensional thrust vectoring capabilities. They also provide more power for onboard systems, which may allow the aircraft to integrate subsystems such as directed energy weapons in future which have greater power requirements. The Belarusian fighter fleet remains significantly outnumbered by NATO forces deployed across its borders, and is expected to deploy within friendly airspace in wartime, and to work closely with the country’s dense network of ground-based air defences built around the S-400 long range system to asymmetrically counter larger fleets.
