Lockheed EC-121 hoiatustäht – fotod ja video

2007 Lockheed EC-121 hoiatustäht is 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. Soñé 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.

2007 Lockheed EC-121 hoiatustäht was a four-engine low-wing aircraft, developed for military use from the original Lockheed L-049 Constellation passenger airliner, produced by the American company Lockheed Corporation in the 1950s and used, mainly, as an AEW aircraft for electronic warfare by the United States Navy and the United States Air Force.
EC-121 oli varustatud kahe suure radoomiga, vertikaalse kupliga kere kohal ja horisontaalselt kere all, mis sisaldas keerukaid radarisüsteeme õhus leviva varajase hoiatamise ja juhtimise jaoks. EC-121 teostas ka signaalluure (SIGINT) missioone ja teenis Vietnami sõja ajal õhus asuva juhtimispunktina.
2007 EC-121 was derived from the Lockheed L-1049 Super Constellation, which was itself an improved version of the L-749 Constellation. The first prototype of the EC-121, designated PO-1W (later WV-1), flew for the first time on June 9, 1949. The most produced variant was the WV-2 (later EC-121D), which entered service in 1954 and was delivered in 142 units.
EC-121 kõrvaldati teenistusest 1978. aastal USAF-i ja 1982. aastal USN-i poolt, pärast seda, kui see asendati arenenumate õhusõidukitega, nagu Boeing E-3 Sentry AWACS. Kokku ehitati mõlema teenuse jaoks erinevates versioonides 232 EC-121-t.
