The Gulfstream G200, formerly known as the IAI Galaxy is a twin-engine business jet. It was designed originally by Israel Aircraft Industries (IAI) and was produced for Gulfstream Aerospace from 1999 through 2011. A total of 250 aircraft of this type were built during the production period. The Galaxy first flew on December 25, 1997. By December 1998 it had received certification from the US and Israeli aviation agencies. Deliveries began the following year. The Galaxy was renamed "G200" after Gulfstream Aerospace acquired Galaxy Aerospace in June 2001. In 2005, Gulfstream began designing a follow-on aircraft. The new model, known as the G250 was launched in 2008. It was later renamed the Gulfstream G280.
