The Gulfstream G280, a super-midsize twin-engine business jet, was first conceptualized in 2005 as a successor to the G200. It took its maiden flight on December 11, 2009, and has remained in production with over 200 units delivered since 2012. Despite Gulfstream's signature oval window design being a well-known feature of their aircraft, the G280 does not include them.
This aircraft resulted from a collaboration between Gulfstream Aerospace and Israel Aerospace Industries (IAI). Design enhancements for the G280 included a glass cockpit, more powerful engines, and a larger wing with heated leading edges. Initially named the G250, the model was renamed to G280 after it was discovered that "250" had negative connotations in some cultures, notably meaning 'stupid' in Mandarin.
The interior and aerodynamic aspects of the wing and empennage were designed by Gulfstream, while IAI handled other design elements including the windows. The cabin length increased by removing the rear fuselage fuel tank. New Honeywell HTF250G turbofan engines were installed alongside a new T-tail with larger stabilizers.
