The G-IV entered into service with serial number 1000 in 1987 and was upgraded to the G IV-SP at serial number 1214 in 1993. It was later redesignated G400at serial number 1500.[2] A short-ranged variant was created based on the original G-IV and designated the G300. With introduction of the G500/G550 (an upgrade to the G-V), the G-IV received an upgrade based on the newly created G550. This created the G450 and its short-ranged variant the G350.
The Gulfstream G400 has a large cabin, long range of 4,350 nautical miles (8,060 km) and the same comfort and design that characterize the G series. Typical cruise height and speed are 45,000 ft and Mach 0.88. Earlier models were fitted with Honeywell's SPZ 8000 Avionics package. The SPZ 8400 Avionics Package was an option, becoming standard on later models . It costs about $15 million at 2009 prices. The replacement for this jet, the G450, has better performance and comes with Honeywell's next generation Primus Epic Avionic Suite, a Honeywell Visual Guidance System (an advanced HUD), the Gulfstream Enhanced Vision System (EVS) and Goodrich Electronic Standy Instruments.
