According to the Svenska Dagbladet, after midnight on Mar. 29 (Good Friday), the Swedish radars detected six fast planes coming from the east, originating from the St. Petersburg area and overflying the Gulf of Finland.

In reality, the route the aircraft were flying wasn't suspect: Russian bombers periodically fly across the Baltic Sea to reach the Russian exclave of Kaliningrad, located between Lithuania and Poland.

However, on Mar. 29, the two Tu-22M3 Backfire heavy bombers, capable of carrying cruise missiles and nuclear weapons, and their four Su-27 Flanker fighter jets escort got dangerously close to the Swedish airspace and, at 2 AM local time, they skirted Gotland island, some 30-40 kilometers off the Swedish territorial waters.

At least two JAS-39 Gripen should always be in a QRA (Quick Reaction Alert) and ready for take off in case of alarm, but quite surprisingly there were no interceptors ready on Good Friday night.

Analysts believe the massive restructuring process that downsized the Swedish Air Force — from 20 squadrons and over 400 planes to four divisions and less than 150 planes — is to blame for the lack of preparedness of the Swedish air defense.
