Homeland Security ordered so many drones it can’t keep them all flying?

The Homeland Security Department ordered so many drones it can’t keep them all flying and doesn’t have a good plan for how to use them, according to a new audit the department’s inspector general released Monday.

In a blunt assessment, investigators said Customs and Border Protection's Office of Air and Marine has a fleet of nine “unmanned aircraft systems” and is awaiting a 10th — though it doesn’t have enough ground support and doesn’t have a good plan for prioritizing missions.

“CBP procured unmanned aircraft before implementing adequate plans,” the investigators said.

The inspector general said given the number of aircraft, CBP should have been able to fly more than 10,000 hours of missions per year, but in the year under review the agency flew less than 4,000 hours.

Underscoring the ad hoc approach, the agency doesn’t have a dedicated budget for running drones, and has had to siphon money from other areas to keep the program afloat. Investigators said the budget woes mean future missions may have to be scrapped — yet the underfunded fleet continues to grow.

“Despite the current underutilization of unmanned aircraft, CBP received two additional aircraft in late 2011 and was awaiting delivery of a tenth aircraft in 2012,” the inspector general said.
