The AH-6 is a light attack and reconnaissance helicopter designed on a combat-proven platform offered in three variants – an AH-6S, offering greater cargo and personnel carriage; an AH-6I for international customers; and an UH-6 Unmanned Little Bird, designed for unmanned flight. Most of its avionics come from the AH-64D Apache Block III, providing 60-70% commonality with the world's most advanced production helicopter. These commonalities reduce training costs, lifecycle costs and simplify field logistics.
