The Nieuport-Delage Sesquiplan was a specialized French racing monoplane that first flew in 1921, representing pure performance-oriented aircraft design. Compact yet powerful, it achieved an extraordinary 300 kilometers per hour maximum speed despite its modest 7.8-meter fuselage and 8.2-meter wingspan. Intended solely for speed competitions, the Sesquiplan embodied the era's fascination with aircraft racing as both entertainment and technical development platform. Its impressive velocity established Nieuport's continued reputation for innovation and performance, cementing the manufacturer's prestige in international aviation circles.
