The Coast Guard acquired a VC-4A from Grumman on 19 March 1963. It was 

based out of National Airport in Washington, D.C. and served as the executive 

transport for the commandant of the Coast Guard. After the Coast Guard 

transferred to the Department of the Transportation, the Secretary of 

Transportation also utilized this aircraft. In September 1983 the VC-4A was 

transferred to Air Station Elizabeth City. 

The Coast Guard ordered a second VC-4A but cancelled the order before 

delivery. 

According to a USCG Memo, dated 20 December 1973, the VC-4A's and the 

VC-11A's authorized use included: 

"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."
