A U.S. Army intelligence aircraft was tracked flying over the Black Sea on Sunday, conducting a surveillance mission in support of U.S. defense operations, according to publicly available flight data. Data from Flightradar24 showed the aircraft, operating under the call sign BRIO66, flying racetrack patterns off the coast of Romania near Constanța before heading southeast over international waters. The ARTEMIS program, developed and managed by Leidos, represents the Army’s effort to modernize its airborne intelligence, surveillance, and reconnaissance (ISR) capabilities. Built on the Bombardier Challenger business jet, the system has been transformed into an advanced signals-intelligence platform capable of detecting, collecting, and analyzing electronic emissions across complex operational environments. Since entering service in 2020, the aircraft have logged more than 10,000 flight hours, demonstrating high reliability while supporting U.S. and allied missions across Europe, the Middle East, and the Indo-Pacific. The U.S. Army describes ARTEMIS as a “critical element” of its evolving multi-domain intelligence framework, designed to deliver real-time situational awareness and targeting data to commanders. Leidos says the system combines commercial airframe efficiency with advanced electronic warfare suites, giving operators greater endurance and faster deployment than legacy ISR aircraft. The flight data from FlightRadar24 The aircraft tracked over the Black Sea on Sunday carried the U.S. registration N159L and is assigned to Lasai Aviation LLC, a U.S. Army contractor. It maintained an altitude of approximately 35,000 feet and a speed of 372 knots during its flight, according to flight monitoring data. The presence of U.S. surveillance aircraft over the Black Sea reflects Washington’s continued effort to monitor the evolving security situation near NATO’s eastern flank.
