CBP Office of Air and Marine

Customs and Border Protection (CBP) Air and Marine Operations (AMO) operate a fleet of ~220 rotary and fixed-wing aircraft used for both CBP (including Border Patrol) and Department of Homeland Security (DHS) ICE operations.
AMO aircraft typically identify themselves on both CBP/BP/ICE radios and aviation radios as "TROY" followed by 2-3 numbers associated with the airframe. Aircraft operating from OCONUS FOLs (Forward Operating Location) use "MAZE" followed by the 3-number airframe association. Until 2021, all aircraft utilized the "OMAHA" callsign.
