) aircraft. In 1964 the unit was redesignated Coast Guard Air Station Arlington and 10 years later, in 1974, Air Station Arlington changed its name to Air Station Washington in recognition of its location at Washington National Airport.
In a USCG Headquarters Memo, dated December 20, 1973, the use of the VC-4A and the VC-11A was defined as follows: “These aircraft are used to provide air transportation on a demand basis, to the Secretary
f Transportationand 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.”
In 1994, Air Station Washington began single aircraft operation and accepted a C-20B

, designated as C-143, to operate as a Medium Range Command and Control Aircraft (MRCCA). As the lease for the Challenger 604 came to close in October 2011, a second Gulfstream V (C-37A) was leased and designated as CG02. The Gulfstream platform provides well-established type certifications and qualifications consistent across the Department of Defense executive fleet with 18 Gulfstream GV derivative aircraft in service.
As of 2022, the Coast Guard took delivery of a new Gulfstream C-37B aircraft, replacing a formerly leased Gulfstream 550, and now owns its entire LRCCA fleet, equipped with commercial and military communications systems, providing secure voice and data capabilities, as well as specialized equipment and sensors to meet Coast Guard mission needs. The C-37B, designated as CG-102, is expected to have a service life of at least 30 years, and joins the existing owned C-37A (CG-101, cn 653) acquired in 2002.
