From defensenews.com: “NATO already has chosen Sigonella as a base for up to eight Block 40 Global Hawks it aims to fly as part of its Allied Ground Surveillence program . . .
The Italian Air Force is, meanwhile, planning to create an air corridor to allow UAVs to take off from Sigonella. Global Hawks will be able to fly from there to Johannesburg and back without refuelling, said Ed Walby, director of business development at Northrop Grumman. “
