The present invention provides a hose and drogue in-flight refueling system that avoids overpressure risks in the refueling operation and optimizes the performance of the fuel supply during its operational life and throughout all the flow rates. The hose (19) and drogue (21) in-flight refueling system comprises a pressure sensing unit (37) capable of measuring continuously the fuel pressure at the end of the hose (19) and a control unit (41) in the tanker aircraft (13) which is operatively communicated through a communication link with the pressure sensing unit (37) and with the fuel pump (33) and is adapted to use the measures of the fuel pressure at the end of the hose (19) to control that the fuel supplied at the beginning of the hose (19) has the pressure needed to achieve a target pressure at the end of the hose (19).
