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 GIV is no longer in production as of September 2003.
Development
The Gulfstream G400 was formerly marketed as the Gulfstream IV-SP. It has a large cabin, long range of 4,350 nautical miles (8,060 km) and the same comfort and design that characterize the G series. Typical cruise height and speed are 45,000 ft and Mach 0.88. Earlier models were fitted with Honeywell's SPZ 8000 Avionics package. An upgrade option was given and became standard in later models and was Honeywell's SPZ 8400 Avionics Package. It costs about $36 million at 2004 prices (leasing is also an option). 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 G-IV was upgraded to the G IV-SP and later redesignated the G400. A short-ranged variant was created based on the original G-IV and designated the G300. With introduction of the G500/G550 (a upgrade to the G-V), the G-IV received an upgrade based on the newly created G550. This created the G450 and its short-ranged variant the G350.
The U.S. military variant of the IV, designated C-20F/G/H Gulfstream IV in Department of Defense service.[2] The C-20F is a G IV model operated by the U.S. Army in a command/executive transport role. The C-20G aircraft[3] may be configured for cargo operations, 26 passenger operations or combinations of the two. 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. With full seating, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four. A hydraulically-operated cargo door is installed on the starboard side of the aircraft, and a ball roller cargo floor is capable of accommodating palletized cargo. C-20G aircraft are operated Fleet Logistics Support Squadron Four Eight (VR-48) and Marine Air Support Detachment (MASD) at Naval Air Facility, Andrews Air Force Base, Washington, DC and at Fleet Logistics Support Wing Detachment, Marine Corps Base Hawaii. The C-20H are G IV-SP models operated by the U.S. Air Force in a command/executive transport role.
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. 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. They can also predict wind shear that will either increase or decrease a hurricane's strength. 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.[4]
In 1990, Gulfstream CEO Allen E. Paulson and a Gulfstream flight crew set 35 international records for around-the-world flight in a Gulfstream IV.
