After the Ukrainian drone attack on St. Petersburg, a Swedish S102B Korpen signals and electronic intelligence aircraft may have monitored the response of Russia’s air defense system, the Telegram channel Military Chronicle reported.

According to the channel’s authors, the Swedish aircraft was primarily interested not in the aftermath of the strike itself, but in the operation of Russian air defense radar systems during the raid. Such an aircraft can record radar emission parameters, track changes in the activity of alert stations, and collect data on how the air defense system reorganizes after a massive UAV attack.

The S102B Korpen belongs to SIGINT and ELINT aircraft. These platforms are used to intercept and analyze radio signals, monitor communication systems, and study radar activity. Therefore, the appearance of such an aircraft after the drone attack is viewed as a possible attempt to obtain information about Russia’s air defense response.

Sweden’s intelligence activity around Russia has intensified since the country joined NATO. In May, Swedish broadcaster SVT reported the launch of Sweden’s first national military satellite, which is also intended to monitor Russian territory. Earlier, there were also reports of S102B Korpen flights over the Baltic Sea after drone strikes on Leningrad Region.

The attack on St. Petersburg took place on the morning of June 3. The UAV threat lasted for several hours. City Governor Alexander Beglov reported a Ukrainian drone strike on Kronstadt, Kirovsky, and Krasnoselsky districts. According to official data, there were injuries, but no deaths.

In Leningrad Region, according to Governor Alexander Drozdenko, 59 drones were shot down overnight. Amid the raid, Russia’s Federal Air Transport Agency temporarily restricted operations at Pulkovo Airport. St. Petersburg residents also received emergency alerts about the UAV threat and possible disruptions to mobile internet.
