1969 – VC-11A Executive Transport Entered Service. The first Turbojet Aircraft in Coast Guard Service
The Coast Guard acquired a single Grumman Gulfstream II in February 1969 as a high speed executive transport for use by the Commandant and the Secretary of Transportation. A turbo-jet, purchased off-the-shelf, it was equipped with an Inertial Navigation System that allowed it to go any place in the world without outside input. It was based out of Washington National Airport.
The Gulfstream II, design number G1159 was the successor to the highly successful G-159 Gulfstream I [VC-4A]. The G1159 design retained much of the G-159 fuselage and was also fitted with dual nose and main-wheels. New wings with 25 degrees of sweep and swept T-tail were designed.
The VC-4A was retained. A USCG Headquarters Memo, dated 20 December 1973, addresses the use of the VC-4A and the VC-11A.
“These aircraft are used to provide air transportation on a demand basis, to the Secretary [of Transportation] and members of his staff, the Commandant, U.S. Coast Guard and members of his staff and such other personnel as may be authorized by the Commandant. The VC-4A is normally used for all flights east of the Mississippi and the VC-11A is normally used only for flights west of the Mississippi or outside CONUS.”
The VC-4A flew for an average of 800 hours per year and carried an average of 7.8 passengers per flight. The VC-11A, on the other hand, flew an average of 600 hours per year and carried an average of 6.5 passengers per flight.
