The Beechcraft RC-12 Guardrail was an airborne signals intelligence (SIGINT) collection platform based on the Beechcraft King Air and Super King Air. While the US military and specifically the United States Army have numerous personnel transport variants of the King Air platforms referred to with the general C-12 designation, the RC-12 specification refers to a heavily modified platform that collects SIGINT through various sensors and onboard processors.
