>US Navy Gulfstream 4 Call Sign CATBRD1
''Commander in Chief Allied Forces Southern Europe (CINCSOUTH) was originally
provided a R6D-1Z (BUNO 128433) prior to 1958. This aircraft was transferred
to VR-1 in 1958 and replaced with a R4Y-1 aircraft (C-131, BUNO 141020).
When BUNO 141020 was assigned there was a contest within the office of CNIC
to come up with a name for the aircraft. At that time, Admiral C. R. Brown
was assigned the post of Commander in Chief Allied Forces Southern Europe. A
much beloved officer, he acquired the nickname of "CAT" as a youngster and
was known so during his long and illustrious naval career. The winning name,
"CATBIRD" was selected and the callsign was officially changed to "CATBIRD
1020.''
