Built as a C-121C for MATS and painted in their markings. Modified to EC-121S in 1967, serving with the Pennsylvania Air National Guard. All electronics equipment removed in April 1979, and displayed at the USAF History & Traditions Museum. Still had some of the EC-121S aerials and attachment rods in this 1987 photo, but they were all removed later.

Built as a C-121C for MATS and painted in their markings. Modified to EC-121S in 1967, serving with the Pennsylvania Air National Guard. All electronics equipment removed in April 1979, and displayed at the USAF History & Traditions Museum. Still had some of the EC-121S aerials and attachment rods in this 1987 photo, but they were all removed later.
