English: From the museum website:
The US Air Force RC-121 and EC-121 series of airborne early warning (AEW) aircraft were modifications of the Lockheed models 1049A and 1049B Super Constellation passenger airliner. US Navy versions were the WV-2. The USAF aircraft entered service in 1953 with the Air Defense Command. Their primary mission was to fly patrols along the U.S. coasts as a part of the Distant Early Warning (DEW) Line. Missions of 10 to 12 hours were common. A total of 72 RC-121Ds were built between 1951 and 1955. They were re-designated EC-121Ds in 1962. In the Vietnam War EC-121s of the 552nd Airborne Early Warning and Control Wing operated as part of the Big Eye Task Force and later, College Eye Task Force. The EC-121s monitored and reported North Vietnamese air traffic, guided U.S. fighters to intercepts, directed aircraft to their aerial refueling tankers and guided rescue aircraft and helicopters to downed pilots. Lockheed Aircraft manufactured the Museum’s EC-121T in Burbank, California in 1954 as a RC-121D. It was delivered to the USAF in October of that year and remained in service for 22 years. It was re-designated EC-121D in 1962 and modified to an EC-121T in 1968. The modification included removal of the height finding radar and its “shark fin” radome from the top of the fuselage. All indictors, navigation equipment, and radios were changed to become a high-speed automated system. During the latter part of the Vietnam War, EC-121Ts were used extensively. Two missions per day were common. 418 flew missions over the Plain of Jars (Laos) and the Gulf of Tonkin about 50 miles from Haiphong Harbor, North Vietnam. From latter 1973 to early 1974, 418 flew missions over Cambodia, providing radar control to cargo aircraft delivering food to the besieged city of Phnom Penh before it fell to communist forces. Missions were also flown in the Yellow Sea between Korea and China. The aircraft was based at Kwang Ju, Korea and Fukuoka, Japan during these missions. During its service, 418’s parent units received the Air Force Outstanding Unit Ribbon with two oak leaf clusters, which are painted on the right side of the fuselage. The large bulge on the bottom of the aircraft is the radome for the AN/APS-95 air search radar that had a range of 250 miles. A number of blade antennas stick out from the fuselage for various electronic purposes. The Museum received transfer documents from the Kansas State Agency from Federal Surplus Property in February 1981 for Conditional Transfer of 418. It was flown to the Forbes Field by Frank Lang from Davis-Monthan in May 1981.
