Russian MiG-31 aircraft armed with Kh-47M2 Kinzhal hypersonic aeroballistic missiles conducted a scheduled flight over neutral waters of the Sea of Japan on March 17, 2026. The Russian Ministry of Defense stated the crews practiced in-flight refueling while adhering to international airspace rules.
The MiG-31, known as the fastest operational combat aircraft with a top speed of around 3,000 km/h, serves as the primary carrier for the Kinzhal missile. This two-seat interceptor features 13 fuel tanks enabling up to seven hours of autonomous flight, a SBI-16 Zaslon radar detecting targets up to 200 km away, and capacity for up to ten air-to-air missiles alongside its six-barreled GSh-23-6 cannon. The MiG-31I variant, optimized for Kinzhal launches, extends range through aerial refueling.
The mission occurred in a strategically vital maritime corridor linking Japan, the Korean Peninsula, and Pacific approaches. MiG-31s provide high-altitude interception of strategic bombers, cruise missiles, and aerial targets, while their high dash speed and altitude deliver the Kinzhal with optimal launch conditions for rapid acceleration. The sortie combined long-range strike demonstration with refueling drills, highlighting sustained operations in the Far East amid regional dynamics including Japanese military modernization and North Korean missile activity.
Accompanying fighters escorted the MiG-31s eastward near Japan’s Shimane Prefecture before returning. Similar patrols underscore Russian Aerospace Forces’ focus on airspace control and deterrence in the Asia-Pacific.
