"The aircraft "Speckled Trout" is an extensively modified C-135C used primarily as an advanced avionics and communications test bed for state-of-the-art guidance, control, navigation, and communication equipment. It is also used to evaluate future transport aircraft design.
The 412th Flight Test Squadron operates the Speckled Trout and manages its test mission.
The name Speckled Trout applies to both the organization and the aircraft. The name was chosen in honor of an early program monitor, Faye Trout, who assisted in numerous phases of the project. The word "speckled" was added because Trout apparently had "a lot of freckles.""
