Gulfstream has secured workshare packages for its newest business jets, the G400 and G800. The airframer has signed a contract with GKN Aerospace for the two models, which extends the partnership between the companies that goes back to 1993. 

GKN will produce the empennage, floorboards, and metal-bonded fuselage panels for the G800, plus the rudder and aluminum machined wing skins for the G400. The rudder and elevator that are part of the empennage will be made using GKN’s thermoplastic technology, with parts some ten percent lighter. The production will take place in The Netherlands (Papendrecht and Hoogeveen), Mexico (Chihuahua), and the US (Wellington).

The work package on the two new jets compliments that on other Gulfstream aircraft. GKN already produces the empennage and fuselage panels for the G650 and G700, plus the rudder and wing skin for the G500 and G600.

Gulfstream unveiled the G800 and G400 last October.. The G800 is the first to be introduced in 2023 and will be the OEM’s ultra-long-range model, capable of flying 8.000 nautical miles. The 800 is an extension of the G650ER and G700 and is a mix of the former’s fuselage with design advances from the latter.

The G400 is derived from the G500 and G600, but some ten feet shorter than the 500. This model is scheduled for delivery from 2025.
