[edit] Design and development

The United States military version for this plane is the C-4 Academe. The TC-4 is a version with added instruments and navigation. It was used by US Navy for bombadier/navigator training for the A-6 Intruder. A VC-4A variant was flown by the United States Coast Guard as an executive transport until the early 1980s. It was later used as a logistics and long-range command and control aircraft until 2001.^[1]

A 38-passenger stretched version, the G-159C, was developed by Gulfstream. Five were delivered from November 1980.^[2] Brockway Air was one among the few airlines to use this version, before its acquisition by Metro Airlines.

[edit] Operational history

In August 2006, a total of 44 Grumman Gulfstream I aircraft remain in service. The major operator is Phoenix Air in the United States with 13 aircraft. Some 19 other airlines also operate the type.^[3]
