The Lockheed EC-121 Warning Star was a United States Navy and United States Air Force Airborne early warning and control radar surveillance aircraft. A military version of the Lockheed L-1049 Super Constellation, it was designed to serve as an airborne early warning system to supplement the Distant Early Warning Line, using two large radomes, a vertical dome above and a horizontal one below the fuselage. EC-121s were also used for intelligence gathering (SIGINT).

dbo:abstract
  • The Lockheed EC-121 Warning Star was a United States Navy and United States Air Force Airborne early warning and control radar surveillance aircraft. A military version of the Lockheed L-1049 Super Constellation, it was designed to serve as an airborne early warning system to supplement the Distant Early Warning Line, using two large radomes, a vertical dome above and a horizontal one below the fuselage. EC-121s were also used for intelligence gathering (SIGINT). It was introduced in 1954 and retired from service in 1978, although a single specially modified EW aircraft remained in service with the U.S. Navy until 1982. The U.S. Navy versions when initially procured were designated WV-1 (PO-1W), WV-2, and WV-3. Warning Stars of the U.S. Air Force served during the Vietnam War as both electronic sensor monitors and as a forerunner to the Boeing E-3 Sentry AWACS. U.S. Air Force aircrews adopted the civil nickname, "Connie" (diminutive of Constellation) as reference, while naval aircrews used the term "Willie Victor" based on a slang version of the NATO phonetic alphabet and the Navy's pre-1962 "WV-" designations for the aircraft type.

  • Il Lockheed EC-121 Warning Star era un quadrimotore ad ala bassa, sviluppo ad uso militare dell'originario Lockheed L-049 Constellation da trasporto passeggeri di linea, prodotto dall'azienda statunitense Lockheed Corporation negli anni cinquanta ed impiegato, prevalentemente come aereo AEW per la guerra elettronica, dall'United States Navy e dall'United States Air Force. Al di là del loro iniziale impiego, con il passare del tempo ed in ragione dell'installazione di differenti apparecchiature elettroniche, gli EC-121 vennero inoltre utilizzati nello spionaggio tramite l'intercettazione delle comunicazioni (SIGINT) e nella lotta antisommergibile. Entrati in servizio nel 1954 vi rimasero fino al 1978; un singolo esemplare (aggiornato e modificato) rimase operativo con la US Navy fino al 1982. (it)
  • Le Lockheed EC-121 Warning Star est un avion de surveillance radar utilisé par l'United States Air Force et l'US Navy entre 1954 et 1978 (bien qu'un exemplaire soit resté encore en service dans la Navy jusqu'en 1982). Il s'agit de la version militaire du Lockheed Constellation et comporte deux grands radômes, un dôme verticale au-dessus et un autre horizontal sous le fuselage. Les EC-121 ont également été utilisés pour la collecte de renseignements (SIGINT). Les versions de l'US Navy initialement acquises (pré-1962) avaient pour désignation WV-1 (PO-1W, seuls deux seront construits en tant que prototypes), WV-2, et WV-3. Les EC-121 ont activement servi en Asie du Sud-Est pendant la guerre du Viêt Nam entre 1965 et 1974 comme précurseurs du Boeing E-3 Sentry, notamment en soutien aux chasseurs de l'USAF engageant les intercepteurs MiG nord-vietnamiens lors des opérations Rolling Thunder et Linebacker I/II. Le EC-121 était surnommé « Connie » (diminutif de Constellation) par les pilotes de l'Air Force et « Willie Victor » par ceux de la marine, basé sur une version argotique de l'alphabet phonétique.

  • Lockheed EC-121 Warning Star – pierwszy amerykański samolot wczesnego ostrzegania i dozoru przestrzeni powietrznej zbudowany na bazie samolotu transportowego Lockheed Super Constellation dla USAF i US Navy. Pełnił rolę samolotu wczesnego ostrzegania dalekich obszarów (m.in w systemie Distant Early Warning Line). Oficjalnie maszyna była nazywana Warning Star, ale częściej określano ją mianem Connie lub Super Connie, zdrobnieniem od nazwy samolotu bazowego Constellation. (pl)
