Swedish Air Force confirmed the interception of Russian fighter jets and intelligence aircraft, by its JAS-39 fighters.
Stockholm, 17 September 2025 — Swedish Air Force JAS 39 Gripen fighters intercepted two Russian Su-30 aircraft carrying KH-31 anti-radar missiles over the Baltic, in what officials and defense analysts describe as yet another show of force by Moscow on the alliance’s doorstep. The Gripens aircraft also intercepted an IL-20 intelligence aircraft.
The Interception
According to reports, Swedish air defense radars detected the two Su-30s flying in international airspace but unusually close to Sweden’s air defense zone. The aircraft were believed to be armed with KH-31 missiles, a type of high-speed anti-radiation weapon designed to destroy enemy radars and surface-to-air missile sites.
In response, a pair of Swedish Gripen jets was scrambled to visually identify and escort the Russian aircraft. The encounter took place without incident, and the Su-30s eventually turned back toward Russian airspace. No violation of Swedish sovereign territory was reported.
Strategic Context
The incident underscores the heightened tensions in the Baltic region since Sweden formally joined NATO in March 2024. Russia has repeatedly conducted air operations close to allied airspace, often with transponders switched off, a pattern NATO has described as both unsafe and provocative.
The presence of KH-31 missiles on the intercepted aircraft raises the stakes, suggesting that the Russian mission was not a simple patrol but a deliberate demonstration of strike capability against NATO air defenses.
About the KH-31
The KH-31 (NATO reporting name AS-17 “Krypton”) is a supersonic missile capable of traveling at speeds up to Mach 3. It comes in both anti-radiation and anti-ship variants, with a range of up to 110 km (68 miles). Its deployment in a border patrol scenario is widely interpreted as a signal of deterrence and intimidation.
