The Unmanned Little Bird Demonstrator is a modified MD 530F single-turbine helicopter designed for optionally manned flight. The platform is capable of dual pilot, single pilot or no pilot flight operations. It can be remotely operated or programmed for autonomous operations in any of these operational modes. The aircraft has safely conducted more than 500 hours of UAV technology flight testing since its first flight in September 2004. The AH-64D Apache is the most advanced multi-role combat helicopter for the U.S. Army and a growing number of international defense forces. The Apache performs across the full spectrum of operations as a force multiplier for Combatant Commanders and supports the safe return of troops.
