YUMA, Ariz. (June 18, 2018) - Participants of NATO’s Unified Vision 18 launch an Aerostat aboard the Yuma Proving Ground in Yuma, Ariz. The Aerostat is used to provide 24 hour surveillance of the battle space and provide ground troops with better security and information. Unified Vision is a bi-annual trial designed to ensure that Joint Intelligence Surveillance and Reconnaissance assets from NATO and the Allies are able to operate together to counter security challenges ranging from conventional threats to terrorism and will contribute to the Alliance’s modernization to face the new threats of the 21st century.
