- G500: The Gulfstream G500 has a reduced fuel capacity. Introduced in 2004 as a shorter 5,800 nautical miles (10,742 km) range version, it has the same exterior appearance, as well as the PlaneView cockpit, but Visual Guidance System (HUD) and Enhanced Vision System (EVS) are options.

- G550 AEW: Israel has acquired a number of G550s, fitted with the IAI EL/W-2085 sensor package (a newer derivative of the Phalcon system) for Airborne Early Warning (AEW) use and named the aircraft Eitam. This aircraft is heavily modified for the AEW role by Gulfstream's partner, Israel Aerospace Industries (IAI), and is also called CAEW (Conformal Airborne Early Warning) by Gulfstream Special Missions Department. Israel has also acquired a number of G550s dubbed SEMA (Special Electronic Missions Aircraft) with systems integration also carried out by IAI. Italy has acquired two G550 CAEW as part of a counter-deal to Israel's $1 billion order for thirty Alenia Aermacchi M-346 Master advanced jet trainers. Singapore ordered four similar G550 CAEW aircraft equipped with the EL/W-2085 sensor package from Gulfstream and IAI.
