STOCKHOLM--Saab said its GlobalEye airborne early warning and control system has been selected by the North Atlantic Treaty Organization as part of its plans to modernize and strengthen its surveillance and situational-awareness capabilities.

The Swedish defense company said Tuesday that NATO Secretary General Mark Rutte has announced that the alliance would begin formal negotiations over the acquisition of up to 10 GlobalEye systems.

NATO is currently holding a summit in Ankara, Turkey.

"At this point, Saab has not signed a contract or received an order related to the announcement," the company said.

Saab's GlobalEye is a command and control system that combines radar and sensors built on a Bombardier jet, providing long-range detection and identification of objects in air, at sea and over land.

The company said GlobalEye will significantly enhance NATO's ability to detect and respond to a wide range of threats, including drones, ballistic and hypersonic missiles.

Saab will now proceed to formal negotiations with the NATO Support and Procurement Agency to secure a contract.

A coalition of 11 countries will jointly negotiate the procurement of the system, NATO said in a separate statement.
