Air-to-Air Refueling is a process that allows military aircraft to refuel in mid-flight, extending their range and operational time. This technique involves a tanker aircraft equipped with special equipment that transfers fuel to another aircraft while both are flying at high speeds and altitudes. During the refueling operation, the receiving aircraft connects to a hose or boom system from the tanker. This enables the transfer of fuel without the need to land, which is crucial for long missions or during combat situations. Air-to-Air Refueling enhances the effectiveness of air operations by allowing planes to stay airborne longer.
