Swept-wing box-type aircraft comprising a fuselage and a lifting system formed by two substantially horizontal wings. One of the wings has a positive sweep angle, while the other has a negative sweep angle, the wings lying in planes spaced apart from one another and joined by two vertical wings extending from their ends. The positively swept wing is the front wing and extends from the bottom of the fuselage, whereas the negatively swept wing is the rear wing and extends generally continuously above the fuselage, the fuselage being provided with a pair of fins at its tail section. The fins are joined at their ends to the rear wing, the fins, the rear wing and the fuselage defining an aerodynamic channel along which the surface of the fuselage is substantially flat.
