EC-121 Warning Star
From The Black Vault Encyclopedia Project
The EC-121 Warning Star was a US Air Force/US Navy version of the Lockheed Constellation designed to serve as an airborne early warning system to supplement the Distant Early Warning Line. It had two large radomes, one above and one below the fuselage. EC-121's were also used for intelligence gathering (SIGINT). It was introduced in 1955 and retired from service in 1978. The US Navy versions when initially procured were designated WV-2/3.
EC-121R BatCat
During the Vietnam War some 30 EC-121s were modified for use with ground sensors to detect enemy troop movents along the Ho Chi Minh Trail. The resulting EC-121R configuration was nicknamed the BatCat. Two BatCats were lost during the war.
