The Lockheed WC-130 is a high-wing, medium-range aircraft used for weather reconnaissance missions by the United States Air Force. The aircraft is a modified version of the C-130 Hercules transport configured with specialized weather instrumentation including a dropsonde deployment/receiver system and crewed by a meteorologist for penetration of tropical cyclones and winter storms to obtain data on movement, size and intensity.

The Air Weather Service (AWS) received its first C-130 Hercules in 1962 to conduct air sampling missions in the wake of a resumption of atmospheric weapons testing by the Soviet Union in September 1961. The Air Force was then in the process of replacing its fleet of WB-50 weather reconnaissance aircraft with WB-47E jets but by 1965 the AWS had decided it would better served by the WC-130 in the manned weather reconnaissance role. Since that year the Air Force and Air Force Reserve have operated a total of 50 WC-130s in five variants. The WC-130J Weatherbird is the current weather data collection platform for the 53rd Weather Reconnaissance Squadron.

Only one WC-130 has been lost on an operational mission, H-model 65-0965, on 12 October 1974.

In 1954 the Air Weather Service (AWS) replaced its WB-29 Superfortresses as its primary weather reconnaissance platform with a fleet of WB-50Ds deployed in seven squadrons. Between 1956 and 1960 six WB-50 accidents resulted in the loss of an entire crew and caused the deaths of 66 crew members; metal fatigue and other structural problems with the type was to end its service by 1965. The C-130 Hercules was desired by the AWS as the best alternative but budgetary limitations prevented the procurement of new aircraft for the mission. Headquarters Air Force had always considered aerial weather reconnaissance an expendable luxury when budget cuts were necessary or when funds were needed for expensive programs. In 1958 its desire to field a large ICBM deterrent force resulted in the shutdown of two AWS squadrons, followed by three more in March 1960. The problems with the WB-50, brought to a head in May 1960 by fuel leaks that grounded the entire 66-plane fleet, accelerated the process, which scheduled a complete phaseout by 1963. AWS fought against the decision, however, and the proposed permanent shutdown of AWS's flying mission alarmed high-level operational commanders worldwide, including the admiral commanding the United States Pacific Command. The commander of the Strategic Air Command, General Thomas S. Power, recommended that the WB-50s be replaced by B-47s that were being phased out by SAC, and when Gen. Curtis E. LeMay gave his support for the proposal, modification of 34 WB-47Es in 1963 for the AWS was approved and the re-activation of three discontinued weather recon squadrons scheduled for 1962.
