    Just to nitpick, calling it Il-476 is not really correct. It is Izd.476. But yeah, its correct Il name is pretty long. :P

    The most correct designation for it would be Il-Weweretoolazytodoitproperly

      Nice Il-476/76MD-90A photos.

      With that light grey colour scheme - are there now "50 Shades of Grey" in the RusAF ??? :diablo:

        It appears that the wing mounted L-band AESAs have commenced production, GRPZ (ГРПЗ)are Tikhomirov-NIIR's production facility. The advertising placard's caption reads "onboard, multifunction digital interrogator with AESA", so the primary use as IFF is confirmed (sorry it's sideways).

          I am pretty clueless on the subject, could someone elaborate on the necessity of such an elaborate IFF?

            I'm not very clear on the subject eighter..
            But the overall point is that the L-Band signal wave travels further than the X-Band Waves. So if they supplement the L-Band signal waves with the main radar, it will enhance the range of IFF prossess. Its important if you travel without AWACS support, but a nice thing to have eighter way.

            Not sure how this work out on the technical level. Cause the L-Band Array is very small in size so... Does it transmit in a Radio wave type of signal or.. ?
            Thanks

              I suspect the story is much the same as is described here for a similar solution on board Gripen NG:

                I was under the impression the L-bands were supposed to be used primarily to pick up LO targets. ( notice I used 'pick up' and not track).

                Is this not so then ?

                  L-band is widely used for area surveillance for all types of objects, e.g. in shipboard long-range radars.

                    Yes, but the ability to pick up LO objects (wavelength etc) was supposed to be the reason they are added on the craft. Is this now revised to an IFF ?

                        A question I'd also like to know the answer to.

                              So from this reference it looks like they are in a short time going onto 3rd generation Asea technology. How does transmitter size compare to USA technology in asea radars

                                It's difficult to comment on specific die size etc. But all indications are that this is GaN, because GaAs MMIC tech has matured and been refined over the last 15 years and commercially available for at least a decade- hence wouldn't require a Russian government funding programme in collaboration with universities to complete development. Commercial applications of GaAs, namely mobile phones have ensured its relatively cheap availability- GaN RF power transistors currently cost substantially more than a similarly sized GaAs device, and would explain Guskov's emphasis on driving down cost as the quantities of GaN devices increase and its processes evolve, manufacturing cost will tumble narrowing the gap between the two.

                                Other indicators are greater efficiency (200km range radar for the Transas UAV), fewer T/R modules are needed as they're optimised for high gain and power, which makes them particularly practical for UAV applications and will shortly debut on USAF UAVs.
                                Guskov's claims of a high resolution of 30cm-50cm SAR is certainly indicative of the high power density associated with GaN - it's more than twice the resolution advertised for the RBE2 (GaAs) AESA.

                                This is a hugely significant development, if they can get it to production in 5 years the timelines would be broadly comparable to the US and certainly ahead of Europe. Kudos.

                                  Been a loong time since i read an article this outstanding!
                                  God knows its a long time between a good VVS coverage.

                                  Anyway, there is an complete list coverage all AB and its structure, ano 2013.
                                  Awesome!
                                  There might be some error here nd there, but we get the big picture.

                                  Just want to point out a little here.

                                  "By 2020 Russia plans to upgrade its remaining operational airfields.
                                  Khalino haveing been completed in sept 2012. The infrastructure at Krymsk is being improved as we speak, and Runway upgrade work under way at Akhtubinsk, Chalovskiy and Engels just to name a few. Work is expected to begin at Voronezh earlier this year. Many other as well, but at a later timeframe."

                                  "The Air Regiment has been replaced by the Air Base(AvB), a term used to describe a military unit(s), not an air base/ airfield.
                                  Under the original reform plan of 2009, a total of 52 AvB of three different grade were formed, replacing 72 regiments, 14 AvB and 12 separate squadrons or detechments. The plan called for the establishment of three different categories of AvB.
                                  1st grade was created from the merger of two or more former Air Regiments.
                                  2nd grade was formed from the assets of atleast one former Air Regiment.
                                  3rd grade would only have one Squadron attached.

                                  However, this plan was revised in mid-2010, and all the 3rd grade AvB was axed, thereby reducing the total of AvB to total of 37.

                                  All Squadrons was then formed into (aviatsionnaya groupa/ AvGr), and subordinated into existing AvB, or relocated into new AvB with the same types of units.
                                  Each AvGr is made up of one or more Squadrons.

                                  At the end of 2010 a new revision began. Exsiting AvBs were once again merged to form so-called 'Super-base' which left only the 1st grade AvBs left.
                                  The st1 grade AvBs that remained, limited to Da(long range aviation), Ta(tactical aviation) and VTA(Transport aviation) units. Each of them now controls a number of AvGrs, some of which are located at seperated Airfields."

                                  The only 2nd grade AvB remaining is AA(Army aviation) helicopter units.
                                  I just read that article, and I have to say while decent (though nothing really new), beware of some details.
                                  There are factual inaccuracies. For example the article says all 9-12 MIG-29s have been withdrawn, but this is clearly false.

                                          Now that's a name I'm real curious about. "Baltimore" in the anglosphere seems to be derived from old Irish/Gaelic Baile an T Mhir, meaning "place/home/town of the big house". This then went straight into the Irish town of Baltimore, the surname of Baltimore and all the places in North America called Baltimore.

                                          So why on earth do the Russians nowadays call Voronezh-B Балтимор/Baltimor? Is there any historical reason for this? Was it coined recently, for fun? Or is the name completely unrelated to the Irish and English ones?

                                          Sorry, I've been bugging this thread with etymology and such several times now but I find it interesting.
