The Nieuport-Delage NiD 450 was a French racing floatplane, originally intended to compete for the 1929 Schneider Trophy. After the French decided not to participate that year, the type was used as the NiD 650 to speed the development of the proposed entrants to the 1931 event, the NiD 651 and NiD 652. Delays in producing the latters' engines left these unflown.
