The Montebello Police Department operates a joint "Air Support Unit" with the neighboring cities of El Monte, Irwindale and Baldwin Park. Together the unit operates three Robinson R-44 patrol helicopters. The unit was initially created in 1993 by the City of El Monte California, but over time other cities came on board to participate in the program.
Eventually the Air Support Unit began providing patrol services to the cities of Baldwin Park, Irwindale and Montebello. The cities of West Covina, Azusa and the Baldwin Park School District Police would be added over time. Currently this Unit operates three Robinson R-44 helicopters that are equipped with Forward Looking Infrared (FLIR), searchlight, public address system, LoJack vehicle recovery system, and computerized moving map.
