The C-37B is the most recent Gulfstream to be adopted for service with the U.S. Government and its military services. As with earlier Gulfstreams, the G550-based C-37B is most often used by the government to transport high priority administration, congressional, and senior Department of Defense and military personnel. The C-37B is outfitted with an advanced communications suite enabling reliable, worldwide, secure data and voice connectivity for U.S. government officials.

The C-37B follows in the footsteps of earlier Gulfstream transports (designated as various models of the C-20) which began service with the U.S. Government and military in 1983. C-20 and C-37 model Gulfstreams serve with every branch of the U.S. military forces and with numerous federal agencies including NASA, National Oceanic and Atmospheric Administration, Federal Emergency Management Agency and others. Gulfstreams are in fact, the only fixed-wing aircraft that serve in every branch of the U.S. military.

Two JCG Gulfstreams fill the Japanese Coast Guard's requirement to survey its extensive ocean patrol areas. The aircraft has a 19-passenger, high-density interior, a belly radome which houses a surveillance radar along with a Forward Looking Infrared (FLIR) system. The radar and FLIR are integrated through software that allows the radar to find a target, pass its location to the FLIR, and to have the FLIR then visually sight and identify the target. The radar, FLIR, and communications suites are operated by on-board mission specialists.

The long range, exceptional endurance, high speed, and operational flexibility of the GV-based JCG aircraft enables the JCG to conduct lengthy broad-area oceanic surveys and patrols. In addition, the aircraft is a superb extended range search and rescue platform as well. The aircraft is capable of ocean surveillance at any altitude from near sea level to 51,000 feet and further, is equipped to drop a variety of search and rescue equipment such as pumps, rafts, radios, and food and water, to those in peril on the sea.

Two highly modified CAEW aircraft were delivered to Elta Systems Ltd., a subsidiary of Israeli Aircraft Industries in 2006 for installation of Elta's conformal airborne early-warning radar system. CAEW provides improved performance compared to previous systems through higher operating altitudes, longer range and increased mission time on station. Further performance advantages result from its capability to quickly direct radar beams in any direction at any time. The Elta system features six multi-purpose operator stations with color monitors.

The system provides rapid target acquisition and information with full 360-degree coverage. The multi-functional Elta EL/W-2085 AEW system includes a phased-array, airborne early-warning radar, and identification friend-or-foe system, electronic support measures (ESM), and electronic intelligence (ELINT) and communications intelligence (COMINT) systems. Its many modes of operation include track initiation, an extended-detection range mode with long dwell times, and target verification.

High Altitude and Long Range research aircraft like its U.S. predecessor, HIAPER, is a high-altitude atmospheric research aircraft for the Deutsches Zentrum für Luft und Raumfahrt (DLR), Germany, with mission objectives and capabilities similar to those of HIAPER. HALO is supported by the German Research Foundation, Max Planck Society, members of the Helmholtz Association of German Research Centres (Helmholtz-Gemeinschaft Deutscher Forschungszentren), and a number of other scientific institutes from the field of atmospheric research. Around 30 research institutes participate in the project.

HALO's exceptional maximum altitude, range, and payload capabilities represent a significant improvement compared with similar research aircraft in operation previously. HALO is designed to maximize payload flexibility but is typically equipped with as many as 15 equipment racks for scientific instrumentation (more than twice as many as on previous DLR aircraft). Even before HALO was delivered, more than 100 instrument proposals were submitted to DLR from the atmospheric science community, including analysis of trace gases and particles, remote sensing Light Detection and Ranging and infrared spectrometers, and instruments for investigating geophysical parameters.

Special Missions and Technology

Special Missions Platforms


Gulfstream aircraft are highly adaptable for a range of uses, whether training NASA pilots or helping hurricane hunters track storms.



The Gulfstream PlaneView™ family of flight decks represents years of research, engineering and pilot input that created and continues to advance the most sophisticated flight decks available in business aviation.



Improving how fast and how far an aircraft flies requires more than engineering a better way to make a jet soar. It also includes examining―even to a molecular level―every material used in manufacturing aircraft to develop something more advanced.
