DERRY TWP., Pa. -

The Pennsylvania State Police have unveiled their next generation of patrol helicopters.

The department took delivery of the first two of six Bell 407GX helicopters at the state police academy in Derry Township, Dauphin County, on Tuesday.

State Police Commissioner Frank Noonan and John Garrison Jr., president and CEO of Bell Helicopter, were on hand for the event.

"We operate six aviation patrol units across the state and provide aerial support to all federal, state and local law enforcement agencies within the state," said Commissioner Frank Noonan, Pennsylvania State Police. "It is very important that we have modern, reliable and mission-ready helicopters to patrol and serve the citizens of the commonwealth."

The 407GX model, according to Bell, features an integrated Garmin G1000H flight deck with twin 10.4-inch high-resolution LCD screens that host primary flight and multi-function displays in an easy-to-scan layout.

One of PSP's six aviation patrol units is based at the Reading Regional Airport in Bern Township, Berks County.
