Gulfstream V
This article is about the C-37A. For the C-37B, see Gulfstream G550.

The Gulfstream V (Model GV, pronounced "G-five") is a large, long-range business jet aircraft produced by Gulfstream Aerospace, derived from the previous Gulfstream IV. It flies up to Mach 0.885 (508 kn; 940 km/h), up to 51,000 feet (16,000 m) and has a 6,500 nmi (12,000 km) range. It typically accommodates four crew and 14 passengers. It first flew on November 28, 1995, and entered service in June 1997.[2] It is used by the US military under the designation C-37A.[3] It is followed by an improved version, the Gulfstream 550 (Model GV-SP).

Development

In the early 1990s, the Gulfstream V (GV) was developed as a response to the Bombardier Global Express.[4] It was certified on April 11, 1997.[5] Capable of flying up to 6,500 nmi (12,000 km), it rolled out in 1995 and was Gulfstream's first ultra-long range business jet. Total production of the Gulfstream V was 193 aircraft.[1] By 2018, 1997-1999 Gulfstream GVs were trading at $8.8-10.25 million.[6] By 2019, a GV was worth around $10 million: below $6 million for a fixer to up to $13 million for a late model low-time aircraft.[4]

Design

Perspective

Compared to the Gulfstream IV, the engines are changed from Rolls-Royce Tay to Rolls-Royce BR700-710A1-10 with increased thrust, higher bypass ratio, and Full Authority Digital Engine Controls (FADEC). Operating ceiling is increased from 45,000 to 51,000 ft (14,000 to 16,000 m). It has thrust reversers and composite flight control surfaces. The horizontal tail area is 30% larger, wingspan is increased from 74.6 to 93.5 ft (22.7 to 28.5 m), the fuselage is lengthened by 5 ft (1.5 m) forward of the main entry door, and by 2 ft (0.6 m) aft of the wing. Maximum takeoff and landing weights are increased by 15%.[5]

It has a new semi supercritical wing for a fuel capacity of 41,000–12,000 lb (18.6–5.4 t) more than the G-IV. The three zone cabin is similar to the G-IV, smaller than the Global Express, while its dispatch reliability, cabin noise and fuel efficiency compare favourably against its competitors of the same era. Compared to the comparably priced Global Express, the GV offers more range and is more fuel efficient while the Bombardier offers better runway performance, a larger cabin and a softer ride. BR710 overhaul comes at 8,000 hour or 10 years if it comes earlier and costs $1.25 million per engine.[4]

Their tail numbers were 50049, 50050 and 60403.One of three aircraft long tasked with evacuating the president in an emergency and preserving the so-called National Command Authorities, the officials with authority to launch nuclear weapons. The C-20Cs had slightly older dial-and-gauge cockpits to help protect the plane from the electromagnetic pulse that would accompany a nearby nuclear explosion. The gear aboard is top-notch, with special satellite communications networks and special classified defensive measures that would protect the plane during an attack.[8]

Civil operators

The majority of G-Vs are operated by corporate and individual owners. Mark Cuban paid $40 million for a Gulfstream V in October 1999, earning a Guinness Record of "largest single e-commerce transaction". Steve Jobs received a Gulfstream V as compensation from Apple in 2000.[9]

On March 11, 2005, Gulfstream delivered an ultra-long-range G-V to the National Center for Atmospheric Research (NCAR). The aircraft—known as the High-performance, Instrumented Airborne Platform for Environmental Research (HIAPER), based in Boulder, Colorado, is being used by environmental and atmospheric scientists from both public and private research facilities.[20] The GV was chosen by NCAR for its exceptionally high cruising altitude, long range, endurance, payload, reliability, and low operating costs, as well as worldwide product support.[21] The HIAPER Gulfstream V is modified to accept wing/pylon mounted instrumentation.
