he Gulfstream G100, formerly known as the Astra SPX, is an Israel Aircraft Industries-manufactured twin-engine business jet, now produced for Gulfstream Aerospace. The United States Air Force designation for the G100 is C-38 Courier.
Astra evolved from the Rockwell Jet Commander, for which IAI had purchased the manufacturing license in 1968, and the IAI West wind. The Astra wing was modified and, with a completely new fuselage, became the Galaxy (later the Gulfstream G200) business jet during the 1990s.
Work on an improved West wind began in the early 1980s, with the prototype making its first flight on 19 March 1984. The first production Astra flew in March 1985, FAA certification came in August 1985 and customer deliveries started in 1986.
The original 1125 Astra was replaced by the Astra SP, announced in 1989; 37 were built. The third variant, Astra SPX, flew in August 1994. This variant was renamed G100 from September 2002 following Gulfstream's acquisition of Galaxy Aerospace, which held the Astra certifications, in May 2001. IAI builds G100s in Israel and then flies the completed airframes to the United States for interior outfitting.
In September 2002 Gulfstream announced the improved G150, based on the G100. This new variant was due in 2005. It has been FAA certified for steep approach.
A C-38A of the District of Columbia Air National Guard
The C-38 Courier is currently in use by the United States Air Force with the 201st Airlift Squadron at Andrews Air Force Base in Maryland. The C-38 replaced the earlier C-21 Learjet. The C-38 differs from the standard Gulfstream G100, featuring military-grade GPS, Tactical Air Navigation, UHF and VHF secure command radio, and Identification friend or foe system.
The C-38 will additionally serve with the United States Navy, replacing North American T-2 Buckeye aircraft at Naval Air Station Patuxent River beginning in September 2015. The C-38 will act as a chase aircraft, radar test target, and pilot proficiency aircraft for the test and evaluation squadron VX-20.

G 150 - A Versatile aircraft
The Gulfstream G150 flies farther at higher Mach speed than any other midsize business aircraft, and does so with one of the lowest direct operating costs per hour in its class, all while consistently maintaining an annual National Business Aviation Association (NBAA) dispatch-reliability rating higher than 99.8 percent. The G150 is so versatile, reliable and efficient, it is the airborne partner of Gulfstream’s Field and Airborne Support Teams.
Fly Coast to Coast Non stop
Because the G150 flies at a faster cruise speed than any other midsize jet, G150 travelers will arrive more than an hour ahead of other aircraft in its class. A maximum operating Mach of 0.85 helped the G150 set 10 world city-pair speed records in its first two years of service.
