The Gulfstream 400 was introduced in 2002 as part of Gulfstream’s transformation of their product line. Technically speaking, the G400 is a G IV SP. The G400 comes with a high level of standard cabin and avionics features, that the only options are a head-up display, security system, and a local area network (LAN) for the cabin.
The G400 production was initiated just after the 500th G IV model was produced and ceased in 2004 when it was succeeded by the G450.
