Overview

The large cabin, long range G400 was introduced by Gulfstream at the 2002 NBAA convention as a replacement for, or revised aircraft description of, the GIV. As manufacture of the GIV series was halted on 2 December, 2002 so production of the G400 began.

First deliveries for entry into service were scheduled for 2003, but only 23 were manufactured and production was phased out shortly after.

Essentially the G400 was a slightly longer GIV with improved weight capability thanks to some strengthening of the landing gear and adjustments to the wing and tail. A hydro-mechanical system replaced the GIV wire brake system while damping of the landing gear system ensured smoother landings and an increased landing weight.

The G400 has a range of 4,100 nm at speeds up to Mach 0.88. It is powered by two 13,850 lbf-rated Rolls-Royce Tay 611-8 engines, and the OEM included a Gulfstream five year service and training package as well as a competitive warranty.

In October 2003 the Tay 611-8C-powered G450 was introduced at NBAA following an unannounced maiden flight. Development had commenced in 2001 under the name GIV-X, and four pre-production units flew between 30 April and 18 September that year.

After more than 1,850 hours of flight testing the FAA granted certification on 12 August, 2004, followed by EASA on 19 November that year. FAA production certification was granted on 29 November, 2004 and the first customer delivery was carried out on 7 May, 2005.

With effect from 1Q2011, the maximum take off weight was increased from 33,521 kg to 33,838 kg and the maximum ramp weight from 33,702 kg to 34,020 kg. This meant the G450 could carry 12 passengers at full fuel load.

The FAA certified Stage 4 noise compliance on 3 November, 2010, while the CIS granted certification in January 2006. Transport Canada approved operations to 13,715m in January 2011, previously restricted to 12,500m.

The decision to end G450 production was made on 21 October, 2016 with final delivery to a customer on 20 January, 2018. In total, 354 G450s were produced.
