In 1963, a second Helicopter was added to the fleet and two years later a third was added. In 1968, a turbine powered Bell 206A Jet Ranger was added to the fleet. This Helicopter significantly decreased police response time. As a result, the "Helicopter Unit" began to respond to unusual occurrences and other police emergencies.
The "Helicopter Unit" experienced major expansion in 1974 and became officially designated as Air Support Division (ASD). Air Support Division consisted of 77 sworn personnel with 15 Helicopters and a Cessna 210 in it's fleet.
