WASHINGTON — The U.S. Air Force is close to deciding on its replacement for its aging fleet of UH-1N Iroquois helicopters, which are currently tasked with security missions as well as protecting America's nuclear missile arsenal.

Manufactured by Bell, UH-1N, the helicopter affectionately called "Huey," first entered service in 1970 to assist in search and rescue missions. Since then, the Air Force has expanded the Huey's role to include flying above nuclear missile silos and VIP transportation.
