The H-24 Siabhra (English: changling) is a multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capabilities manufactured by the Ossorian aerospace defense company Tionscail Ríoga Aeraspáis (TRA). The Siabhra is designed to combine the versatility and functionality of a conventional helicopter with the long-range, high-speed cruising performance of a turboprop aircraft.
