The Lockheed Martin KC-130 is a military aerial refueling aircraft based on the C-130 Hercules transport plane. It is primarily used by the United States Marine Corps to extend the range and endurance of various aircraft, including fighter jets and helicopters. The KC-130 can refuel in-flight, allowing for longer missions without the need for landing. Equipped with advanced technology, the KC-130 features a hose-and-drogue system for refueling, which is compatible with many NATO aircraft. It also has the capability to perform cargo transport and medical evacuation missions, making it a versatile asset in military operations.
