The Blériot-SPAD S.45 was a passenger aircraft built by in 1921.

circular section monocoque fuselage constructed of three layers of plywood.

It was powered by four 300 hp Hispano-Suiza engines. These were mounted in a pair of laminated wood nacelles mounted on the lower wing, each containing two engines mounted in tandem, one driving a tractor propeller and the other a pusher propeller

Pilot and flight engineer sat side-by-side in an open cockpit immediatly in front of the passenger compartment, with the navigator#wireless operator occupying a compartment in the extreme nose of the aircraft.

Exhibited in an unfinished condition at the 1921 Paris Aero Salon

Difficulty in carrying out static load testing on the monocoque fuselage delayed the granting of a certificate of airworthiness
