The Gulfstream IV is a significantly improved, larger, longer ranging and advanced development of the earlier Gulfstream II and III models.



The most significant improvement with the G-IV over the earlier
Gulfstream models are the Rolls-Royce Tay turbofans, which bring
significant fuel burn and noise emission improvements despite their
higher thrust output than the II and III’s Speys (the IV continues
a Gulfstream and Rolls-Royce association that dates back to the
original Dart powered Gulfstream I). Other changes include a stretched
fuselage and aerodynamically and structurally improved wing with
30% fewer parts, greater fuel capacity and range, increased span
tailplane and an advanced EFIS avionics suite with six colour CRT
displays.

Design work on the IV began in early 1983, with the first of four
production prototypes making the type’s first flight on September
19 1985. FAA certification was awarded on April 22 1987. The improved
Gulfstream IV-SP (SP = Special Performance), with higher payload
and landing weights and improved payload range performance, replaced
the IV from September 1992.



A third development is the special mission SRA-4. Designed primarily
for military roles (such as maritime patrol and electronic surveillance,
depending on equipment fit) it is also offered as a freighter for
priority cargo transport (the US Navy has ordered four and the Marines
one as C-20G operations support aircraft capable of accommodating
26 passengers or three freight pallets).

Both the Gulfstream IV and IV-SP have set a number of records. A
Gulfstream IV flew west around the world over 36,800km (19,890nm)
in June 1987 in a time of 45hr 25min, setting 22 class world records,
another flew east around the world in February 1988, setting 11
class world records. More recently a IV-SP set new world speed and
distance records on a routine business flight from Tokyo to Alberquerque
in the USA in March 1993.

    I agree with Ray K about the Gulfstream G-V and Bombardier Global Express. I did a performance analysis on Bombardier Global Express, and in the relation we compared wing loading and power/weight ratio, and these two airplanes in the graph were almost coincident (and difficult to read). G-V and Global Express are powered by the same kind of engine(maybe not the same version), dimensions and performances are really similar and they have no directly comparable competitors ..or smaller business jet like learjet(part of Bombardier company) or Falcon (by Dassault), but these are smaller and shorter range, or airliners converted into business-jets(like BBJ that is 737, or B-727BJ), these are larger and more expensive but they have usually shorter range than G-V and GlobalExpress
