Il-22 COOT (ILYUSHIN) Coot C
'Coot-C' reporting name is believed to be applied to the ELINT platform encountered by Canadian CF-18s during the late 1980s and early 1990s. This may be the same as configuration shown on Russian television in early 1999. This lacked the underfuselage SLAR-type fairing but had a comprehensive antenna group above the fuselage, with large, swept 'hockey stick' antennas over rear part of cabin.
In early 1999 a new variant of Russia's Il-22 Coot-B Strategic Airborne Command Post (ABNCP) was shown briefly on Russian TV taking off from an unnamed base. The aircraft differed from the two earlier variants, the Il-22 Zebra and Il-22M Bizon, in that it did not have long tube-like under fuselage pods (on the Il-22 that is about 65ft [20m] long, while on the Il-22M it is around 30ft [9m] in length). Instead, there were two large 'hockey stick' antennae on top of the fuselage and one of similar size on the underside. It is possible that this variant had been in existence for some time and had only now been revealed, since there have been previous reports of Il-22s without the long under fuselage antennae. However, the latter aircraft was also without the fin-top cigar-like antenna which is present on the new variant.
Following the major restructuring of Russia's military forces in 1998, it is possible that the role of the Il-22 had also been redefined. In keeping with these changes, the new antenna array may possibly be serving as a communications suite biased more towards a shorter range theater-level task.
Complex EW "Porubschik" was installed on board the IL-20 reconnaissance aircraft (modification called Il-22PP). Equipment "Porubschika" operates in the passive search mode, and after the detection of the target sets the direction of interference. Features of the complex allow the radio to drown out a dot of the enemy in a narrow range, without interfering with their radio equipment using the adjacent frequency.
Testing of the new system of electronic warfare (EW) "Porubschik" was completed in 2013. The tests conducted Flight Research Institute named after Gromov in Zhukovsky, and afterwards the aircraft IL-22 with special equipment faced state tests before sending it to the Russian Air Force. The state tests of the complex were scheduled to be completed by the end of 2014.
A key feature of the new ECM system is the possibility of directional jamming electronic devices, such as radar or drone control system. It is argued that "Porubschik" is able to fix the long-range radar detection aircraft activity of the AWACS, the Patriot air defense systems, as well as items unmanned vehicle control consisting in the NATO arsenal. After detecting the activity of the EW system selectively induces interference in a certain direction at a given frequency, and thus does not interfere with its own means of communication and observation.
The IL-22 (type IL-18/20/22/38 of 1979, not to be confused with an experimental Il-22 of 1947), was chosen because of the lack of other aircraft with the required technical parameters. The aircraft passed the overhaul at the Experimental Machine-Building Plant named Myasishcheva, where it was equipped with everything necessary for complex electronic warfare equipment. It is assumed that because of the limited "Porubschik" resource platform for electronic warfare aircraft will have to change in the next ten years, but so far the plans involved the supply to the Air Force of five such aircraft.
