The deal is worth nearly $63.5 million, the company said.
"We welcome this new contract for our field-proven Falco UAS that confirms the operational reliability and performance of the system, from the sensors to the mission system, delivering outstanding 24/7 all-weather, day and night surveillance," said Fabrizio Giulianini, chief executive officer of Selex ES.
"This year has been an exciting year for our UAS capability, thanks to follow-on contracts for our unmanned surveillance service business, flight campaigns of our top-of-the-range Falco EVO and the acquisition of a launch customer for our platform agnostic SkyISTAR mission system."
The contract from the unidentified country comes on the heels of Selex ES receiving a contract from the United Nations to operate Falco in support of U.N. peacekeeping operations in the Democratic Republic of Congo.
Falco is a medium-altitude, medium-endurance UAS designed to supply net-centric command and control and target cueing. Payloads include AESA radar.
