capacity was envisioned to be 55 to 65 seats. Envoy 7 Fairchild Dornier also launched a corporate jet version of the 728, referred to as the Envoy 7, which was foreseen to enter service around 2004. The Envoy 7 would have featured intercontinental range and would be equipped with Fairchild Dornier's "Super Shark" winglets. Corporate versions of the 528 and 928, marketed as the Envoy 5 and Envoy 9 respectively, were also planned for. Airborne Early Warning Fairchild Dornier unveiled an airborne early warning and control (AEW&C) variant of the 728 during mid-2001. The company proposed developing the aircraft in conjunction with American defense firm Northrop Grumman, outfitted it with the radar and other systems of the E-2 Hawkeye; it also envisioned the development of further special mission variants, such as maritime patrol aircraft and an aerial refuelling tanker.
