Great link. I was not aware that we had a Spectre shot down at the Battle of Khafji in 1991 and another shot down during our stint in Somolia.
"The AC-130U gunship airframe is integrated with an armor protection system (APS), high resolution sensors (All Light Level Television (ALLTV), infrared detection set (IDS) and strike radar), avionics and EW systems, a sophisticated software controlled fire control system, and an armament suite consisting of side-firing, trainable 25mm, 40mm, and 105mm guns. The strike radar provides the first gunship capability for all weather/night target acquisition and strike."
I love phrases like "armament suite." :)
