Operational Context

KAI KUH-1 Surion — twin-engine military utility helicopter

The Surion first flew in 2010 and entered service in 2012. Developed with international cooperation, it features a four-blade main rotor and modern avionics. The helicopter is designed for troop transport and general support missions.

Powered by two turboshaft engines producing approximately 1,800 shaft horsepower each, the Surion cruises at around 140 knots (259 km/h). Maximum takeoff weight exceeds 19,000 pounds (8,618 kg). The cabin can accommodate up to 13 troops depending on configuration.

The Surion has gradually replaced older helicopters in South Korean service. Specialized variants support medical evacuation and maritime roles. The aircraft represents a key achievement in domestic helicopter development.
