History

1997 - On February 16, Deputy Patrick "Pat" S. Coyle, 42, died after the ASTREA helicopter in which he and pilot Ron Hobson were flying crashed in Sycamore Canyon, northeast of Santee, California. His death marked the first fatality in the then 25-year history of the sheriff's air support unit.

2003 - Cedar Fire and Paradise Fire

2005 - ASTREA receives two refurbished Bell 205A-1++ "Super Huey" firefighting helicopters. These are the first two aircraft purchased for the new regional fire helicopter program the county started after the October 2003 wildfires. Both are single-engine, medium-lift copters equipped with 375 gallon underbelly water tanks. The helicopters arrived at Gillespie Field after a three-day, 2,000-mile flight from Eagle Copters of Calgary, Canada. They are designated Copter 10 and 12.

2008 - A new Bell 407 is acquired and equipped to support law enforcement and command and control missions.

2015 - ASTREA adds a Bell 407GX to the fleet (N972PC). On September 29, ASTREA receives a third Bell 205A-1. Like the first two, Copter 11 was rebuilt by Eagle Copters and flown from Calgary to El Cajon.

2019 - The first two of four Bell 407GXi were delivered.

2020 - The third Bell 407GXi were delivered. (N709WG) The WG registration letters are the initials of the former Sheriff William Gore.
