Gulfstream G100

Israel Aerospace Industries (IAI) developed the Astra from its Model 1124 Westwind business jet. Work on an improved Westwind began in the late 1970s, with the first prototype flight on 19 March 1984. The first production Astra flew on 20 March 1985, with FAA certification granted on 29 August 1985 and customer deliveries starting in 1986. It has been certified for the steeper-than-normal approach path required to land at London City Airport. IAI continued to manufacture G150s in Israel and the completed airframes were then flown to Dallas in the U.S. for interior outfitting. In September 2016, Gulfstream announced that, owing to slow sales, production would be stopped, with delivery of the final aircraft due in mid-2017. The Astra was further developed in the 1990s; the wing was modified and mated to a completely new fuselage. This development became the IAI Galaxy (later the Gulfstream G200). By 2018, Gulfstream G150s from 2006–2008 were in the range of $3.8 to $4.8 million. ==Operational history==

of the United States Air National Guard The G100 was ordered for the United States Air Force in 1997 as the C-38A Courier. The C-38A was operated by the 201st Airlift Squadron at Andrews Air Force Base in Maryland until 2015. The C-38A replaced the earlier Learjet C-21. The C-38A differs from the standard Gulfstream G100, being fitted with various military avionics systems. The C-38A was also ordered for the United States Navy, replacing North American T-2 Buckeyes at Naval Air Station Patuxent River beginning in September 2015. Two aircraft remain in service as of 2023, both former 201st Airlift Squadron C-38's. The C-38 is tasked with acting as a chase plane, radar test target, and pilot proficiency aircraft for the test and evaluation squadron VX-20. In 2012, an IAI Astra operated by the Eritrean Air Force as the Eritrean presidential aircraft was stolen by two pilots, both serving Eritrean Air Force officers. They flew the Astra to Saudi Arabia and requested political asylum after landing at Jizan Regional Airport. ==Variants==
