The testing evaluated the Grey Wolf's electronic warfare systems and avionics within the highly controlled, radio frequency-isolated environment of the BAF, which is vital for validating its survivability against electromagnetic threats.

The MH-139 Grey Wolf is fundamentally designed to replace the Air Force's aging UH-1N Huey fleet, with its primary mission being the security and surveillance of the nation's intercontinental ballistic missile sites.

Beyond nuclear security, the Grey Wolf's advanced capabilities—including greater speed, range, and lifting capacity—will enable it to take on other vital roles. These include airlift of distinguished visitors, search and rescue, disaster response, and support for other priority security and transport missions for Air Force Global Strike Command and other major commands, making it a truly multi-mission platform.

The completion of this phase is a key step toward the helicopter's operational deployment for the Air Force.
