                         G1159C  Gulfstream 4
    Around 200 of the original model Gulfstream 4 were built before the upgraded SP was introduced.  The aircraft is longer than the G3 and is powered by Rolls Royce Tay mk 611-8 turbofans.  The construction number sequence started at number 1000.  The Gulf 4 can accommodate up to nineteen passengers and first flew on 19th September 1985.  It is 54 inches longer than a Gulf 3 allowing for an extra window on each side.  The other obvious difference is the size of the engines.

    Gulfstream 4 - MPA
    Several Gulfstream 4's have been built for special missions use, including marine patrol variants for the air forces of Sweden and Japan (illustrated above).  Changes to the basic G4 include a cargo door and reduced number of windows.  Installation of the cargo door involves major structural changes that affect sixty percent of the airframe and take a considerable time to complete

    G1159 Gulfstream 5
    .The Gulfstream 5 is currently being built in tandem with the G4SP, the first time that two Gulfstream models have been built concurrently.  It is powered by Rolls Royce BR710 engines and has a range of over  12,000km. Other changes to the GS4 include a 2m longer fuselage, 5m longer wings and six cabin windows.  Construction numbers begin at no.501 and the G5 first flew on 28th September 1995.  An identification feature is the length and also a squarer tail top compared to that of it's predecessor.  199 were built before the model was superceded by the G500/550 series.
