Development
Developed from the earlier Wib.3 the Wibault 7 was a C.I category single-seat high-wing braced parasol monoplane fighter powered by a 480 hp (358 kW) Gnome-Rhone 9Ad radial engine. The main difference from earlier aircraft was the use of an all-metal construction system which was patented by Wibault. The first prototype flew in 1924, and was followed by two more prototypes. Despite only being placed third in the competition (behind the Nieuport-Delage NiD 42 and the Gourdou-Leseurre GL.32), an order for 25 Wib.7s was placed in January 1927. These were followed in production by 60 aircraft for the French Air Force as the Wib.72 which entered service in 1929. Twenty six Wib.7s were built for Chile under licence by Vickers in England. Plans to build the aircraft in Poland by the PZL company did not happen, although the company did deliver three aircraft fitted with Wright radial engines and 25 Wibault 72s to the Polish military. The next variant was the Wib.73 with seven built for Paraguay. The French navy bought some carrier-capable Wib.74s with strengthened fuselage and arrestor hook.

Famous quotes containing the word development:
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“Fascism, the more it considers and observes the future and the development of humanity, quite apart from political considerations of the moment, believes neither in the possibility nor the utility of perpetual peace.”
—Benito Mussolini (1883–1945)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
