      This might be an old question but.. i kinda need reminder. What's the empty weight of the latest Su-35's ? Surely it's not 16.8 metric ton figure for the early Su-27S's but i wonder if 18-19 metric ton empty weight estimate realistic. and some 20-22 ton for the operating empty weight where the plane is fitted with with some weapons, equipment including pilot.

        I don't think the Su-35S is at the very same empty weight as it Twin- Su-30SM. The larger canopy, duplication of systems, the hydro-electro mounted with Carnards. Same for top air break.
        Reinforced internal support for heavy load like Brahmos class weapons.
        On contrary to popular believe, the Su-35S somewhat follow the Su-27 linage, with that it is NOT certified to carry Brahmos class weapons on its Senter hardpoints. It is neighter piped for EFT under wing stations(customer optional). Stuff like this free up weight.

        That said, its not near the Su-27SK empty weight.
        You could try to contact Sukhoi..

        Edit;
        Didn't Sukhoi advs the Su-35S with four missiles and 50% fuel at 25000kg. Only that 50% fuel could be anything. We all know the senter Fueltanks on Su-35S is quite larger vs vanila Flanker.

        Remember to retract four Pylons and adapter, Canon with rounds, five Flare cartridges etc for true empty weight.

            Thanks Paralay.

            and @Haavarla

            Well if only Sukhoi willing to answer ;w; You know i tried to correspond with some Mil company, the first was French manufacturer for Galix countermeasure. and later i tried to contact GRPZ Ryazan for information and possible picture of experimental Soyuz radar set (What supposedly N001 myech should be) But well... it seems i hold not enough credentials for asking ;w;

                weight empty (Su-30MKK) 24900 - 570 (weapons) - 5270 (fuel) - 200 (pilots) = 18860 kg (equipped with pylons), normal - 24900 kg
                weight empty (Su-30MKI) 25700 - 570 (weapons) - 5270 (fuel) - 200 (pilots) = 19660 kg (equipped with pylons), normal - 25700 kg
                the maximum weight - 38800 kg (weapons 8000 kg + 100% of fuel)

                  Could you break down the Su-35S weight?
                  Thanks

                    Su-35S, combat load
                    4 RVV-MD, 4 x 106 kg = 424 kg. 4 P-72 x 49 kg = 196 kg.
                    6 RVV-SD, 6 x 190 kg = 1140 kg. AKU-170E 6 x 61 kg = 366 kg.
                    2 RVV-BD, 2 x 510 kg = 1020 kg. AKU-58AE 2 x 186 kg = 372 kg.
                    424 kg + 196 kg + 1140 kg + 366 kg + 1020 kg + 372 kg = 3518 kg

                    4 RVV-MD, 4 x 106 kg = 424 kg. 4 P-72 x 49 kg = 196 kg.
                    4 RVV-SD, 4 x 190 kg = 760 kg. AKU-170E 4 x 61 kg = 244 kg.
                    4 RVV-BD, 4 x 510 kg = 2040 kg. AKU-58AE 4 x 186 kg = 744 kg. distance of 200 km / 300 km, warhead. 60 kg.
                    424 kg + 196 kg + 760 kg + 244 kg + 2040 kg + 744 kg = 4408 kg

                    Take-off weight in this configuration
                    19300 (empty) + 100 kg (pilot) + 11500 kg (fuel) + 4408 kg (load) = 35308 kg
                    Flight distance in this configuration with a load of 3300 km.
                    RCS in this configuration.
                    RCS min. = 2.5 sq.m.
                    RCS = (2.5 m + 12 m) * 0.5 = 7.25 sq.m.

                      Interesting, finally some of the goodies @ MAKS 2017 that nobody seemed to care about seeping through. SOLT-25, for Su-25SM3:

                        Better than Klyon, but i hope later bunchs of SM3 will be equipped with a T/220 targeting pod.

                            This episode is on the Nebo-M complex. They are quoting a range of 1800 km and altitude coverage of 1200 km for the VHF variant. Besides low RCS VLO aircrafts, the complex can also detect and track ballistic missiles.

                            The ability to detect and track commercial micro and mini drones is also shown.The VHF unit detects the hexacpoter at a distance of 7km at 100 metres.

                              wow.. Looks amazing. AFAIK Low band system for EW often have MTI or STC applied that will reject low speed target (Thus birds, etc will not clutter the radar screen) The long range Radar may also usually have kinda long pulse which will eclipse target at short distance. Or perhaps the radar can identify the drone based on modulation caused by its rotors.

                                Its 1800 km in Static mode for Circular scan mode its 600 km.

                                No disrespect to their work but they need to move to High Power GaN module , Most of their competitor has moved to 1 or 2nd Gen Ga/N TR module while Ruskies has been working on Ga/A types or its improved derivatives.

                                If I am not wrong Nebo-M works in 3m HF wavelength and this is good to detect any thing between F-22 to J-10 to PAK-FA but not good for bigger B-2 types that would need a 10m wavelength , Building a mobile HF radar should be next challenge else they would have to reply on Static OTH Container radar which has wavelength of 10-100m but due to their static nature its good only for peace time survellence.

                                  Nebo-M is in production for sometime, naturally it won't have GaN modules. However domestic work on such modules has been going on for some years, and not only for Su-57.

                                    PiBu is claiming Kh-38M was ready for production in 2015, and laser-guided variant (Kh-38ML) according to Tactical Missile corps is in production since 2016. The IR Kh-38MT is supposed to finish trials this year.

                                    So we are finally moving past Kh-25 and 29 in VKS munition inventories.

                                    The Kh-38ME shown off @ MAKS2017 had modified fins compared to the mockups that have been floating around for some time now:

                                      How big/heavy are these Kh-38? Warhead etc

                                      I imagine Su-34 could carry 5 of them. But can Flankers do the same?
                                      Thanks

                                        Around 500 kg, it however vary depending from versions for 4,2 lenght and 31 cm diameter.
                                        Warhead is about 250 kg, so it sits quite exactly between Kh-25 and Kh-29 in terms of weight (i think so that almost the former will survive for a while for when a lighter punch would be preferable).
                                        New Aspide -like pentagonal fins are clearly for the Su-57 or for a three-pack storage.

                                          What's the range for the new Kh-38 variants?

                                          I've read 3-40km online, but this seems a little bit low for a missile whose dimensions and overall weight seem more in line with a medium sized powered stand off weapon?
