The Gulfstream G200, formerly known as the IAI Galaxy is a twin-engine business jet. It was designed originally by Israel Aircraft Industries and is produced for Gulfstream Aerospace. The Gulfstream G250 is an improved version under development by Gulfstream and Israel Aerospace Industries (IAI).[1]

Design and development
Gulfstream G200
The G200 was originally named "Astra Galaxy". Israel Aircraft Industries' subsidiary Galaxy Aerospace Inc began designing the Galaxy in the late 1980s in a risk-sharing partnership with the Soviet aircraft design bureau Yakovlev OKB.[2] In September 1993, the program was officially launched. Yakovlev handled design and manufacturing of the forward fuselage and empennage. But it was failing to keep the production schedule and the partnership was ended in 1995.[3][4] This lead to EADS Sogerma sharing manufacturing with the responsibility for the fuselage and tail of the Galaxy. IAI handled final assembly and other prime contractor duties.[5]
The Galaxy was developed from the IAI Astra. The Galaxy has a wing based on the Astra wing, and features winglets. It also has a wider and longer fuselage.[5] The wing has Kruger flaps, slats, and trailing edge flaps. The aircraft also has a cruciform tail, PW306A engines, and a Collins Pro-Line 4 glass cockpit.[6] It uses rubber de-ice boots on wing and horizontal stabilizer leading edges. Most jets today use engine bleed air to heat these areas. The aircraft has seating configurations for 8 to 10 passengers.[6]
The Galaxy's first flight occurred on December 25, 1997. In December 1998 the Galaxy was certified by the American and Israeli aviation agencies. Deliveries of the aircraft began the following year.[5] It was introduced into service in 1999.[6] The Galaxy was renamed "G200" following Gulfstream Aerospace acquiring Galaxy Aerospace in June 2001.[7]
Gulfstream G250
Since 2005 Gulfstream has been working on a follow-up aircraft, the G250, which was launched in 2008, with major improvements, like new glass cockpit and engines, bigger wing, heated leading edges, and other refinements.[8][9]
The G250 is a derivative of the G200, with many improvements, among them increased cabin length, new engine HTF7250G, new cruciform tail, wing bleed anti-ice, cabin with 4 more windows and access from it to the baggage compartment. It will compete against the Hawker 4000, Bombardier Challenger 300 and the planned Embraer Legacy 500. The fuselage, empenage and landing gear will be manufactured by IAI, the wing by Spirit AeroSystems, while the final assembly will be performed by Gulfstream.[8][9]

The first G250 first flew on December 11, 2009 from Tel Aviv, Israel.[10] The aircraft is planned to receive type certification in 2011, then enter service shortly afterwards.[11]
