360: 345: 985:" inside the North Vietnamese border with China, to provide alerts to US aircraft nearing the buffer zone and to report border crossing violations by US aircraft. This could not be done from the gulf, so a third orbit, Ethan Charlie, was created in Laos. After tests in June and August, regular missions began 24 August. Not enough EC-121s or crews were available to support three orbits twice daily, so the Laotian orbit was only flown every third day, with Ethan Bravo missions cancelled on those days. After 13 October 1966, the Charlie orbit was flown every day and the Bravo orbit suspended altogether. In April 1967, four more EC-121s were deployed, to Thailand on 29 May, making for a total strength of three College Eyes in Taiwan and six in Thailand. 2077: 1335: 1251: 1053: 1428: 1885: 1140: 166: 970: 174: 40: 1266: 623: 783: 724:, Florida, in early 1976. The active duty force continued providing personnel to operate the EC-121s on a 24-hour basis, assigning Detachment 1, 20th Air Defence Squadron to Homestead AFB as associate active duty crews to fly the AFRES-owned aircraft. Besides monitoring Cuban waters, these last Warning Stars also operated from NAS Keflavik. Final EC-121 ops ended in September 1978. Detachment 1 dissolved and 79th AEWCS was redesignated a fighter squadron on 1 October 1978. 1811: 1195: 1327: 767:, providing radar early warning and limited airborne control of USAF fighter forces engaging MiG interceptors. Flying orbits over the Gulf of Tonkin and later over Laos, they were the forerunners of AWACS aircraft. The USN used a variant, the NC-121, in their Blue Eagle unit from 1965–1972. Blue Eagles were television- and radio-broadcasting airplanes. The Blue Eagles were based at NAS Patuxent River and were part of oceanographic squadron VXN-8. 1343: 911:. If, for any reason, the MiGCAP could not rendezvous, the EC-121s cancelled their mission. Air-conditioning systems aboard the EC-121 were virtually useless in this profile, and the heat produced by the electronics, combined with the threat of being shot down, made Alpha orbit missions in particular very stressful. On 10 July 1965, in its first airborne-controlled interception, an EC-121 provided warning to a pair of USAF 1074:

an NSA SIGINT asset and subject to even more stringent rules protecting knowledge of its existence. Even when real-time warnings to US aircraft were finally permitted in mid-1972, fighter crews were not made aware of the source of the warnings and because EC-121 radio communications were poor, mandating the use of a radio relay aircraft that often failed, they tended to disregard the credibility of the source.

The final maintenance efforts by Yanks Air Museum Restoration Director Frank Wright included a rebuild of engine #4 in early January 2012. 53-0548 departed Camarillo at 12:10PM on Saturday, 14 January 2012 for the 90-minute flight to Chino, where it will become a static display. 897:. A major disadvantage of this arrangement, however, was that most MiG contacts were beyond the 70 miles (110 km) range of the Big Eye's APS-45 Height Finder radar, so that they were unable to provide this data to USAF strike forces. Furthermore, technical shortcomings in the EC-121D's systems precluded either controlling a fighter intercept or identifying a specific flight under attack. 560:, along with other popular programs of the time in addition to Vietnamese programs recorded prior to each flight . Nightly American news broadcasts were transmitted live using an onboard TV studio and an Air Force newscaster bringing the latest news from home and the world. The "Blue Eagles" operated out of Saigon and Danang Air Bases for around 5 years commencing in 1965. 323:

as sensor-monitoring aircraft. Of the 74 EC-121s, 42 were converted to the EC-121H upgrade beginning in 1962, and in 1969, 15 of the remaining EC-121Ds and seven of the EC-121Hs were further upgraded into the final operational variant, the EC-121T, serving as an AWACS prototype in Southeast Asia in 1972. Five EC-121Ds were modified to be broadcasting aircraft for

1065:, this modified EC-121K (later redesignated EC-121M) carried the QRC-248 newly installed in the College Eye aircraft and also had electronic interrogators capable of reading two additional Soviet transponders, the SRO-1 and SOD-57. Its electronics were custom built rather than off-the-shelf. Its most important upgrade was the top-secret 1782: 532:, 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.

As Frog 01 began its climb to the higher Bravo orbit, it experienced a ruptured oil line forcing shutdown of one engine. As planned, Frog 02 became the primary aircraft when Frog 01 made an emergency landing at Danang.

1167:

On 6 July 1972, as the result of seven F-4 Phantoms shot down in a two-week period, a second Disco track was initiated. Flown near the former Alpha orbit over the Gulf of Tonkin, its purpose was to gain better low-altitude coverage in the Hanoi area. At the end of the month, Disco was also integrated

Despite this advantage, Rivet Top experienced two problems, reducing its effectiveness. Its operators did not have radar scopes to correlate intercepted conversations with specific flights of MiGs, thus could not determine which US aircraft might be under attack. Secondly, like QRC-248, Rivet Gym was

In the last week of August, however, after a period of intensive training and revision of tactics, the MiGs began engaging US strike forces again, scoring a number of kills. Then, Seventh Air Force finally obtained permission for the new Ethan Bravo mission EC-121 to actively interrogate with QRC-248

From April 1965 to early 1966 and beginning again in late 1967, the EC-121Ds also controlled a flight of MiGCAP fighters for unarmed support aircraft operating over the Tonkin Gulf. The EC-121Ds also served as an airborne communications relay center for strike aircraft to transmit mission results and

The USAF received 10 RC-121C and 74 EC-121D Warning Stars also based on the L-1049, beginning with diversions from the Navy contracts in October 1953. The 10 RC-121Cs became trainers, designated TC-121C. Between 1966 and 1969, 30 retired USN EC-121s were transferred to USAF and converted in EC-121Rs

On 15 August 1973, Disco EC-121s flew their final combat mission and on 1 June 1974, Det.1 was permanently withdrawn from Southeast Asia. Between 1965 and 1973, the EC-121s flew 13,921 combat missions, more than 98,000 accident-free flying hours, assisted in the shoot-down of 25 MiGs, and supported

When Operation Linebacker began on 10 May 1972, Disco was one of two principal GCI radars used by US forces, although it continued to be handicapped by poor radio communications. In addition, its slow-turning radar limited its value as a controller of fighters during MiG engagements, while the size

At the onset of Rolling Thunder, the North Vietnamese had an advantage in that their radar coverage could detect most US strike aircraft flying at or above 5,000 feet (1,500 m) virtually anywhere in the country, using a system that was difficult to jam. US forces countered with radar ships

618:

The USAF operated EC-121s between 1954 and 1978, with three wings at maximum employment and three independent squadrons as operations wound down. Until the Vietnam War, their primary mission was to provide complementary early warning radar coverage to the Pacific and Atlantic barriers by flying
