Weather Reconnaissance Squadron FOUR (VW-4) operated WV-3-"cum"-WC-121s between 1954 and 1975 as Hurricane Hunters, with its primary base at NAS Jacksonville, Florida and a forward base at Naval Station Roosevelt Roads, Puerto Rico. Its Pacific counterpart, Weather Reconnaissance Squadron Three (VW-3) Typhoon Trackers was the operational weather squadron in the Pacific, flying from NAS Agana, Guam, tracking typhoons from 1955 to 1960. On June 30, 1960 Weather Reconnaissance Squadron Three, VW-3, disbanded and many of its aircraft (8 - BuNo. 145 series) and crews were absorbed by VW-1, which retained AEW designation and took on the weather commitments and the Title of "Typhoon Trackers" of VW-3. VW-4 later transitioned to WP-3A Orion.
