U vezi sa onim ekranom -stabilizatorom ,izgleda da zaista to neki avioni imaju a opet neki i nemaju ...
Citat:За обтекателями шасси установлены большие по размерам поверхности горизонтального
оперения, которые, по-видимому, потребовались для компенсации моментов, создаваемых поворотным обтекателем РЛС.А-50 ,но есть еще мнение, что это не дополнительное горизонтальное оперение, а обтекатели каких то антенн  Они появились уже после доработок в войсках, поэтому есть не на всех самолетах.
Специалисты подскажите плиз????
Jos dva detalja ,`leteci tanjir`-radar i `pozlacena` stakla prozora kabine zbog zastite od velikog intenziteta zracenja . Ispod sive boje radio-prozracne oplate tanjirolikog kucista radara se nazire zelena a tom bojom su cesto farbani recimo radarski konusi kod Su-27S/P/UB .

zixo ::Подписан контракт на поставку Индии еще двух самолетов ДРЛО и управления А-50ЭИ
[Link mogu videti samo ulogovani korisnici]
Ovim ce Indija uskoro imati 5 aviona A-50EI .U pitanju su transportni Il-76MD koji se konvertuju ugradnjom radarskog kompleksa Falkon , izraelskog AESA-radara IAI Elta EL/W-2090.
Citat:The EL/W-2090 is a further development of EL/M-2075 and EL/W-2085.
The EL/W-2090 uses the active electronically scanned array (AESA), an active phased array radar. This radar consists of an array transmit/receive (T/R) modules that allow a beam to be electronically steered, making a physically rotating rotodome unnecessary. AESA radars operate on a pseudorandom set of frequencies and also have very short scanning rates, which makes them difficult to detect and jam.
Inace Indija je ranije pozajmila jedan ruski A-50 ( veoma moguce onaj Bort 50 crveni kao izvozni A-50E )
Citat:В 1998 г. один А-50 был переоборудован в А-50Э для возможной продажи на экспорт. В этом варианте он был продемонстрирован в 1988 г., в Кубинке, председателю объединенного комитета начальников штабов Индии адмиралу Надкарни.
Один из серийных самолетов в 1997-1999 гг. был переоборудован на ТАНТК им. Г.М.Бериева в вариант АИ для установки израильского радиоэлектронного комплекса.
В апреле 2000 г. один А-50 был взят ВВС Индии в краткосрочную аренду у ВВС России. Всего было выполнено десять полетов, каждый продолжительностью до 6 часов. Пилотировал машину российский экипаж из состава авиационной базы боевого применения самолетов РЛДН, которому и принадлежала машина, но в полетах принимали участие и индийские специалисты. Базировался А-50 на аэродроме Чандиханг (штат Пенджаб).
Citat:
The Indian Air Force (IAF) has been keen to acquire an effective AWACS system for many years to give it a competitive edge in it’s long running dispute with Pakistan. In early April 2000 Russia agreed to lease two A-50 Mainstay aircraft to the IAF and during July 2000 these aircraft were used along the border with Pakistan to see exactly how far inside the other country the radar could identify targets. Eventually in 2004 India decided not to buy the A-50 Mainstay ‘off-the-shelf’ and instead concluded a $1.1 billion deal with Israel Aircraft Industries (IAI) for them to install a version of their Phalcon radar on three IL-76MD aircraft. The first aircraft was delivered from the Tashket factory in Uzbekistan to the IAI factory in Israel in Apr 2005 and the other two following in May and June 2005. The first IL-76MD fitted with the Phalcon radar will be delivered around Dec 2007, with the second aircraft following in Sep 2008 and the final aircraft in Mar 2009.
Interesantno je da je prvi ugovor za 3x A-50EI iznosio 1.1 milijardu dolara a sad ovaj novi ugovor za 2x nova A-50EI cak cirka 1 milijardu .
Citat:Sale to India
In March 2004, as a part of a tri-partite deal among Israel, India, and Russia, Israel and India signed a US$1.1 billion deal according to which IAI would deliver the Indian Air Force three AEW&C radar systems, each of which was worth approximately $350 million. India signed a deal with Ilyushin of Russia for the supply of three Il-76 A-50 heavy airlifters, which were to be used as platforms for these radar systems, for an additional US $500 million. In 2008, media reports suggested that India and Israel were about to sign a deal for three additional radars. India received its first AWACS on 25 May 2009. It landed in Jamnagar AFB in Gujarat completing its 8 hour long journey from Israel.
In November, 2016, India signed another deal to purchase two more AEW&C radar systems. The deal entails a purchase of further 2 systems of the AWACS for $1billion with deliveries scheduled within the next 3 years.
Ruje spram njih modernizuju jedan A-50 na nivo A-50U za `svega` 60 milki dolara pri cemu su sposobnosti radarske i el. opreme veoma moguce ako ne i sigurno ispred one u A-50EI .
Dok su Indusi veoma lako dolazili do izraelske radarske i el. opreme i tehnike, Kinezima je taj put bio dosta otezan ,naravno kocili su ih ko drugi do Ameri. Kitajci su jos 1992 bili zainteresovani za ruske A-50 .
Citat:
China has been in the market for a AWACS system since the early 1990’s and in 1992 they began discussions with Russia about the possibility of purchasing the A-50 Mainstay. However, rather like the Indian Air Force, the Chinese decided that what they really needed was a more effective radar system mounted on the Il-76, rather than the A-50 Mainstay ‘off-the-shelf’ and the radar they wanted was again the Israeli ‘Phalcon’ system. In 1994 they began negotiations with Russia and Israel for the purchase and conversion of four AWACS aircraft worth about $1 billion. Then in 1996 the three sides reached agreement for the supply of one Phalcon equipped Il-76 aircraft, known as a Beriev A-501, and the following year this deal was extended to include the option of three more aircraft in a contract worth over $1 billion. In Oct 1999 an A-50 airframe was flown to Israel to allow IAI to begin installation of the Phalcon system and by May 2000 this work was almost complete – but then international politics came into play. The US administration had always been against the Chinese acquiring advanced military technology that could be used to threaten Taiwan and the Phalcon AWACS system would give the PLAAF a significant military and technological capability that, in the best Chinese tradition, they would soon copy and then eventually improve. After intense pressure from the USA, in July 2000 Israel finally cancelled the deal, stripped the aircraft of the Phalcon equipment and returned it to China via Russia in 2002.Nevertheless, although their plan to acquire advanced western technology has been scuppered at the last minute, this made the Chinese all the more determined to press ahead their AWACS aircraft, albeit considerably less capable than the Phalcon would have been. Work on the A-501 airframe began in 2002 almost as soon as it returned from Russia at the Xi’an Aircraft Industry Company (XAC) to install a conventional rotordome over the fuselage. The rotordome is believed to contain a non-rotating Chinese manufactured Phased Array Radar (PAR) laid out in a triangle of three modules to provide 360 degree coverage. At least two of these aircraft, known as the KJ-2000, have been converted to this particular configuration and these have been seen undertaking flight tests since 2003 at the Chinese Flight Test Establishment at Nanjing.
Citat:Sale to China
In 1994, Israel entered into talks with China regarding the sale of the Phalcon radar system, initially for four units but with an understanding that as many as eight would be procured. An agreement between China and Israel was signed in July 1996. Russia entered the program in March 1997; the first Il-76 slated for modifications landed in Israel in October 1999. Although the US government was aware of the sale, it remained silent until October 1999, when it publicly opposed the sale of the EL/W-2090 to China. Fearing that the system would alter the military balance in the Taiwan Strait, American officials threatened to withhold aid to Israel in April 2000 if the deal proceeded.
On 12 July 2000, Prime Minister Ehud Barak announced that Israel would scrap the deal.However, it was not until July 2000 when a formal letter was sent to the Chinese government; the Israeli government hoped that the newly elected Bush administration would endorse the Phalcon deal. In March 2002, Israel concluded a $350-million compensation package to China, more than the $160-million advance payment China had already made. Subsequently, the original Chinese KJ-2000 AEW&C entered service in 2004.

Citat:
Po Bort brojevima : 10,15 i 20 crveni ,prototipovi dakle konv. iz pomenutih tr.aviona .Serijski su bili Bort-ovi : 30,31,32,33,34,35,36,37,38,38,40,41,42,43,45,46 ( 2x ) ,47,48,49,50,51(2x sa tim da je jedan avion imao Bort broj crvene a drugi plave boje ) i 52 ( svi dakle crvene boje sem jednog 51 plavi ) .Ono sto je zanimljivo je da svega 8 aviona ima civilne reg.oznake( RF- ) .
Na 2:00 se cini kao da je Bort br. 42 plavi ???
Steta sto se civil reg. broj ne vidi dobro, no ipak se cini da je u pitanju Bort 42 crveni a ne plavi ( mala opticka varka pa se crvena boja cini plavom )
Evo ga `42 crveni` i oznaka RF-50610
RF-50610 / 42 RED (cn 0083484538)
