===WC-130E (1965–1993)===
In 1965 the Air Force procured six E-model variants to replace six [[Boeing B-47 Stratojet|WB-47Es]] in the [[54th Weather Reconnaissance Squadron]] at [[Anderson Air Force Base]], [[Guam]].<ref>Fuller (1990), p. 355</ref> Three veteran airlifters were transferred from the [[Tactical Air Command]] (TAC) and three obtained new.<ref group=n>The six E-models were serial numbers 61-2360, 61-2365, 61-2366 and 64-0552 through -0554.</ref> All were modified with the AMT-1 dropsonde system and assigned to the 54th WRS, where they remained until 1972. From then to 1987, when they were assigned permanently to the 53d WRS, the E-models were assigned to the operational demands of all the operational weather reconnaissance squadrons. In 1989 they were upgraded with the Improved Weather Reconnaissance System ("I-Wars") utilizing the [[Omega (navigation system)|Omega Navigation System]]<ref group=n>"I-Wars" consists of three semi-independent sub-systems: the Atmospheric Distributed Data System (ADDS) which records and computes flight level meteorological data from various angle-of-attack probes, the radar altimeter, the pressure altimeter, ambient temperature and dewpoint sensors, and navigation data; the Dropsonde Windfinding System (DWS) which processes temperature, pressure, humidity, wind speed and direction data received from a dropsonde; and the Satellite Communication system (SATCOM). The ADDS generates measurements in the horizontal aspect ("horizontal data"), the DWS in the vertical ("vertical data"), and the SATCOM provides immediate direct transfer of the data to the user.</ref> previously installed in WC-130H model and remained in regular operational service until retired in 1993.
