Russian fighter jet breaches NATO airspace

A Russian Su-30 fighter jet entered Estonian airspace without permission on 18 March, marking the first such violation reported this year.

The aircraft crossed into Estonian airspace near Vaindloo Island for approximately one minute during the afternoon, according to Estonian authorities.

Officials said the jet did not have a filed flight plan and was not in communication with Estonian air traffic control at the time of the incident. The Italian Air Force detachment based at Ämari Air Base responded to the incursion, launching a reconnaissance flight as part of NATO’s Baltic Air Policing mission.

The incident prompted a diplomatic response, with Estonia’s Ministry of Foreign Affairs summoning the chargé d’affaires of the Russian Embassy and issuing a formal note.

Airspace violations in the Baltic region are closely monitored by NATO, with allied aircraft regularly scrambled to intercept or observe Russian military activity near alliance borders.

This marks the first confirmed breach of Estonian airspace by a Russian aircraft in 2026.

The Sukhoi Su-30 is a twin-engine, two-seat multirole fighter developed by Sukhoi from the Su-27, with its first flight in 1989 and entry into service in the early 1990s. Designed for all-weather operations, it combines air-to-air and strike capabilities and is known for its high manoeuvrability. The aircraft remains in production, with multiple variants tailored for domestic and export customers. More than 630 have been built, and it is operated by several air forces, including those of Russia, India and Algeria.

The platform has evolved through a number of variants such as the Su-30SM, Su-30MKI and Su-30MKK, reflecting differing avionics, mission systems and customer requirements. The Su-30SM, introduced in 2013, is among the primary versions in Russian service. As of 2024, the Russian Aerospace Forces were reported to operate around 130 aircraft across different sub-variants, alongside additional aircraft in naval aviation.

In terms of design, the Su-30 has a crew of two and measures just under 22 metres in length with a wingspan of 14.7 metres. It is powered by two afterburning turbofan engines, enabling a maximum speed of around Mach 2 and a service ceiling of approximately 17,300 metres. The aircraft has a range of about 3,000 kilometres at altitude and is capable of sustaining high g-forces, reflecting its role as a manoeuvrable combat aircraft.

The aircraft is equipped with a 30 mm cannon and up to 12 hardpoints, allowing it to carry a wide mix of air-to-air missiles, precision-guided munitions, anti-ship and anti-radiation weapons. Avionics vary by variant but typically include phased-array radar systems, infrared search and track, and helmet-mounted targeting.
