C-37A
The C-37A, a military version of the Gulfstream V business jet will, along with the 1st Airlift Squadron's new C-32As, replace the wing's aging fleet of C-137s. The first C-37A, Tail No. 70400, arrived at Andrews AFB in July 1998, and a second model arrived in September. They will join the squadron's fleet of five C-20Bs, two C-20Hs and three C-9Cs. On 06 January 1999 Gulfstream Aerospace Corp. was awarded a $38,530,875 face value increase to a firm-fixed-price contract to provide for one C-37A aircraft and associated training and data with an expected contract completion date of 30 June 30 2000.

The C-37A resembles the C-20H (Gulfstream IV), but is eight feet longer, with a wider wing span, a more advanced avionics package and greater performance capabilities, allowing the aircraft to carry up to 12 passengers a distance 50 percent greater than the C-20B models. A typical C-37A mission will able to fly 5,500 nautical miles without refueling, carrying Cabinet secretaries, congressional delegations or senior military leaders.

First deliveries of the the ultra-long-range Gulfstream V to commercial customers began at the end of 1996. On 05 May 1997 -- Gulfstream Aerospace Corporation announced that the Gulfstream V, the world's first ultra-long range business jet, had been selected by the United States Air Force (USAF) for the VC-X program to expand the mission capability of the nation's Special Air Mission Wing. The selection by the USAF marked the first sale of the ultra-long range Gulfstream V to the military and opened this market worldwide for similar applications of this new aircraft. The initial contract is for two Gulfstream V aircraft with options for up to four additional units before 2003. The initial contract is valued at $68.9million. Including options, the total contract is valued at more than $275 million. Gulfstream will provide technical and logistics support, spare parts and overhaul services to the USAF for 10 years.

With this aircraft, the 89th Airlift Wing is capable of taking senior leadership nonstop to areas of the world that previously required flying much larger aircraft. The key to C-37A's performance is its state-of-the-art wing design, improved aerodynamics and more powerful engines. The airframe is capable of low-speed, high-lift performance, high-altitude maneuverability and turbulence tolerance. The BMW/Rolls-Royce BR710-48 engines moves the C-37A at a cruising speed of 600 mph. Civilian versions of the aircraft have in a very short time set 15 world speed and distance records, including the first nonstop flight from New York to Tokyo. The Gulfstream V is the first aircraft of its kind, capable of cruising at altitudes up to 51,000 feet, high above most other air traffic, weather and adverse winds.
Despite its more powerful engines, the C-37A is very fuel-efficient. Passengers can comfortably travel in the aircraft at altitudes as high as 51,000 feet, taking advantage of better fuel consumption rates, explained Bigler.

C-37As come equipped with a number of features not found on any other business jets. The avionics system is a state-of-the-art Honeywell SPZ-8500 Flight Management System with an integrated full-function Heads-Up Display. The FMS allows crews to program computers to have the aircraft arrive at point in space at a specific time. They also come equipped with enhanced Ground Proximity Warning System, and Microwave Landing System. Other important features include Tacan military navigation equipment and a military Identification Friend/Foe transponder. Full Authority Digital Engine Controls ensure critical engine operating parameters are maintained. The C-37A, like other Gulfstream Vs, meets the Extended Range with Two-Engine Airplanes standards, a criterion previously only met by larger commercial aircraft operating over long stretches of water.

Passengers will enjoy flying on what Gulfstream claims is the quietest aircraft in production. The twin engines are located aft of the cabin bulkheads; titanium mufflers and vibration isolators will eliminate hydraulic system noise. Insulated side panels, and re-engineered windows further eliminate outside noise. The interior package includes a passenger flight information display system that can feature real-time global positioning on a moving world map, weather updates and other important information.

The 89th Airlift Wing is the only unit in the Air Force to operate C-37 and C-32 aircraft.



The CINC Support Aircraft Replacement Program calls for a most probable quantity of five FAA certified commercial intercontinental passenger Aircraft accommodating a minimum of 12 passengers and 5 Crew in a working office environment and capable of dispatch on short notice to any suitable airfield in the world from operating locations at MacDill AFB, FL and Hickam AFB, HI. This aircraft shall have a 5000 NM range, a separate Distinguished Visitor (DV) area, and worldwide clear and secure voice, facsimile, and PC data passenger communications.

「灣流」V/C-37型飛機

　　C-37是「灣流」V商務噴氣機的軍用型。同C-32S型一樣，C-37將逐漸取代美國空軍第89空運聯隊的已經快要退役的C-137運輸機。首架C-37A（70400號）於1998年7月抵達安德魯斯空軍基地，第89聯隊在這個基地有5架C-20B、2架C-20H和3架C-9C。

　　C-37A型機類似C-20H（「灣流」IV），但要比C-20H長大約8英尺，翼展更寬，安裝了更加先進的電子設備並且具備更好的性能。同C-20H相比，C-37A能夠搭載12名旅客，這足足比C-20B多了一半。C-37在執行一個典型的任務時可以連續飛行5500海里而無需加油，乘客則主要是內閣官員、國會議員或者軍方高層人員。

　　C-37型飛機的成功之道在於其可用「藝術級設計」形容的先進機翼和先進的航電設備以及強勁的引擎。機身設計使飛機可以良好的適應低速、高空機動和亂流乾擾，而且能夠與機翼配合獲得較高的升力。飛機使用BMW/羅.羅合作的BR710-48發動機，這種發動機能夠讓飛機以600英里的時速巡航飛行。民用型的「灣流」V曾經創下了15項關於速度和續航能力的飛行世界紀錄，包括一次從紐約到東京的不著陸飛行。「灣流」V是「灣流」系列中最新的高性能機型，它能夠在51000英尺高度巡航飛行，這個高度高於大多數航線，能夠充分避免天氣、氣流帶來的干擾，從而使飛行更加舒適。

　　C-37A裝備了很多現役飛機沒有裝備的最先進的設備。航電系統採用了霍你威爾公司最新型的SPZ-8500飛行管理系統(FMS)，這套系統在飛機上安裝了能夠全信息顯示的平視顯示器(HUD，多用於戰鬥機)。此外，飛機還裝備了近地警告系統(GPWS)、微波助降系統、塔康導航設備(TACAN)，作為軍機還裝備了敵我識別設備(IFF)。

　　C-37飛機目前主要駐紮在麥克迪爾空軍基地、安德魯斯空軍基地和比利時的Chievres。
