VMFA117_Poko Posted July 19, 2007 Posted July 19, 2007 Today i read the article which sais: "In 80's of 20th century Russian Air Forces (WWS) stated desire to have a special combat version of two-seater Su-27UB which could become a long-range interceptor called Su-27PU. When this aircraft had not been accapted by WWS Suchoi offered it again under the name of Su-30...". Other publication sais that "Su-27PU is in fact Su-30..." Why PU version had not been accepted? Because of financial cuts in budget in the dusk of USSR structure (7 models were built - 5 are still in duty)? Because of limited capabilities of its radar? How much PU was different from Su-30?

Because of financial cuts in budget in the dusk of USSR structure Yes apparently. (7 models were built - 5 are still in duty)? AFAIK none of these original Su-30s are still in "in duty" in Russia. As I understand it, the handful or so aircraft were flying as evaluation airframes and reclaimed by Sukhoi when it became clear that the Russian airforce wasn't interested/couldn't afford inducting the type into actual service at the time. I heard that these airframes were later re-used as basis for the prototypes of the new advanced export versions(Su-30MK). The Su-30 was exported as the "Su-30K"(downgraded export version) though. India is still operating some of these, which I believe are to be re-build to -MKI standard over time. Because of limited capabilities of its radar? Well the Su-30 has the same NIIP-N001 radar as the Su-27, but a more capable EOS system also fitted to the Su-33. However, the Su-30 supposedly had extended data-linking capability over the Su-27 and the idea behind it was for it to either link up into a network with other Su-30s and this way cover a large area(similar to the operation of the MiG-31) or to act as mission controller or "mini AWACS" for a flight of single seat Su-27s. Apparently the Su-30K export version didn't have these extra capabilities and as such was little more than an Su-27UB with a better EOS and added inflight-refueling capability. How much PU was different from Su-30? No difference - same aircraft, new name. Just around the time the Su-27PU came about, Sukhoi decided to rename new variants of the Su-27 with the -3X suffixes....supposedly in order to help distinguish them from the base versions(Su-27 and Su-27UB): Su-27PU -> Su-30 Su-27K -> Su-33 Su-27M -> Su-35 Su-27IB -> Su-34 So as it says in your initial quote: "Su-27PU is in fact Su-30" :) 1 JJ

Another cool feature of the Su-27UB is a couple of internal R-73’s @Alfa, Can you confirm this?

thesystem Posted July 20, 2007 Posted July 20, 2007 the UB....can it internly carry it!? Don't realy think so..? Its a trainer?:huh: DCS World, A10C, AV8B, M2k, FA18C, FC3, MIG21
Alfa Posted July 20, 2007 Posted July 20, 2007 Another cool feature of the Su-27UB is a couple of internal R-73’s @Alfa, Can you confirm this? Do you mean Su-27PU?(Su-27UB is just the two-seat combat-trainer version). No there are no internal weapons bays :) . The Su-27PU/Su-30 is really just an Su-27UB modified for interceptor duties - among the modifications are: * Retractable IFR probe * Rear seat with separate HDD for the radar operator * Updated(more capable) EOS as compared with the system of the Su-27 * Extended data-linking capability (as described earlier). Bear in mind that we are talking about the very first Su-30 version. Later Su-30 multirole incarnations are very different from this - and in fact very different from each other. The advanced multirole variant(Su-30MK) is marketed solely as an export item, which in turn means that the individual customer can pick and choose between varies features and how they want the aircraft configured. - JJ.

I can’t remember were I heard it! But if I recall correct a Su-35/37 or some experimental su-27xx/30 was having 2 internal r-73’s.

Force_Feedback Posted July 21, 2007 Posted July 21, 2007 Probably free falcon or whatever, the 20 year old Su-47/S-37 has internal weapon bays, but it's a tech demonstrator. Creedence Clearwater Revival:worthy:
