Gulfstream G400

and can move palletized cargo and passenger mixes similar to the C-20G aircraft operated by the U.S. The Gulfstream IV (or G-IV) and derivatives are a family of private jet aircraft produced by Gulfstream Aerospace, a General Dynamics company based in Savannah, Georgia, United States.

The C-20J is a G IV-SP model operated by the U.S. Typical cruise height and speed are 45,000 ft and Mach 0.88.

The replacement for this jet, the G450, has better performance and comes with Honeywell s next generation Primus Epic Avionic Suite, a Honeywell Visual Guidance System (an advanced HUD), the Gulfstream Enhanced Vision System (EVS) and Goodrich Electronic Standy Instruments. The U.S. The SPZ 8400 Avionics Package was an option, becoming standard on later models .

Army in a command/executive transport role. The National Oceanic and Atmospheric Administration (NOAA) operates a IV-SP modified to fly scientists and crew members at 45,000 feet around tropical cyclones. The aircraft was modified to drop instruments called dropsondes to measure windspeed, barometric pressure, humidity, and temperature as they fall to the surface of the ocean.

With passengers seats removed, it may be configured as three pallets with no passengers or two pallets and eight passengers or one pallet and fourteen passengers. By sampling the cyclone with these dropsondes over a 4,000 mile track around the storm, the forecasters at NOAA s National Hurricane Center and Hurricane Research Division can better predict where the hurricane will be steered by the upper level winds.

The G-IV SP is particularly suitable for the mission since it is fast, and can fly long distances with ample cabin space for the crew and instruments. In 1990, Gulfstream CEO Allen E. Navy and Marines. The Sultan of Johor operates a G-IV. The Royal Netherlands Air Force operates a single G-IV SP in a commander / government transport role. The Saudi Arabian Minister of Finance and Economy operates a G-IV (G300). The Swedish Air Force operates two highly modified G-IVs in a SIGINT role.

The aircraft are designated S-102B Korpen (Raven). The G-IV ceased production in 2003. The G-IV entered into service with serial number 1000 in 1987 and was upgraded to the G IV-SP at serial number 1214 in 1993.

It was later redesignated G400 at serial number 1500. With full seating, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four.

It costs about $15 million at 2009 prices. It is to be replaced by a G550 in early 2009. The Venezuelan Air Force operates a G-IV in a commander / executive transport role.
