General Atomics on Thursday said it has signed a contract to supply MQ-9B SkyGuardian unmanned aircraft systems (UAS) to the Belgium Ministry of Defense.

The value of the contract, a Foreign Military Sale through the U.S. Air Force, wasn’t disclosed. First delivery is expected in 2023.

The contract includes electro-optic/infrared video and synthetic aperture radar/ground moving target indicator surveillance payloads, ground control stations, pre- and post-flight equipment, ground support equipment and spares.

“Through our Belgian R&D seed-funding initiative, we are connected with many Belgian companies interested in further improving the capabilities of the SkyGuardian system,” Linden Blue, CEO of General Atomics’ Aeronautical Systems, Inc. business, said in a statement.

The SkyGuardian has been selected by the United Kingdom Ministry of Defence and the Australian Defence Force. The system was designed to meet NATO standards.
