The UH-1Y is the most significant upgrade ever made to the venerable and battle-proven H-1 helicopter. At the heart of the upgrade is a new four-bladed, all-composite and ballistically tolerant (up to 23 mm) rotor system.

Originating from a concept demonstrator delivered to the U.S. Army in 1962 based upon a UH-1 Huey, the AH-1 is the world’s first attack helicopter.
