          Something has been bothering me lately about the RCS values of the fire control radars of the S-400 in which I need to have clarified if anyone has info on.

          http://aviationweek.com/technology/n...tection-claims
          It retains the basic advantages of VHF: NNIRT says that the Chinese DF-15 short-range ballistic missile has a 0.002 m2 RCS in X-band, but is 0.6 m2 in VHF.


          https://www.scmp.com/news/china/mili...defence-system

          "
          PLA Rocket Force reportedly shot down a simulated ballistic target almost 250km (155 miles) away and moving at 3km (1.9 miles) per second"


          2007 fire control radar 4m2 at 390kms, 2015 nebo-m 1m2 at 480kms. However these 2 quotes from those sources have really mindf**ked me. I am not doubting that a SRBM would have a .002m2 RCS in X-band because of its size, less exposed surface area than an aircraft and possibly aerodynamic design but what bothers me is that sources have suggested they have intercepted a SRBM like target from about 250kms away.
          anti-ballistic missile is part of its description and it meets the 250km description(china said almost 250km which can be 241250kms they would have said simply said 240km if it was below but they did not) So we have our missile and it has the speed of mach 6.5 2.2295km/s and the SRBM they tested was able to travel 3km/s.

          110 seconds and multiply 2.2295km/s and I got 245.245kms. Multiply 110 seconds with 3km/s we get 330kms than add that to 245kms to determine where it was tracked before it got intercepted at 245kms. An/tpy-2 made in 2008 was said to be able to track .01m2 at 600kms it operates in megawatts like the S-400s fire control radars but yet S-400s are said to intercept IRBMs and MRBMs like THAADs. I am sure that if the S-400 having a 2015 1m2 value at a 480km range would not be strong enough to intercept a SRBM target from far away or even offer way less performance than THAADs. Can someone better clarify this?

            The SCMP seems to have mixed the range against typical airborne target which is 250 Km for 48N6E3. Against ballistic missile, the envelope for S-400 with 48N6E3 is 60 km.

            and the RCS value corresponds to its Warhead and from frontal aspect. the missile itself when launched at boost will have much larger RCS and being exposed from side aspect during its boost. Regarding the difference of RCS value, you have to understand that there is relationship between wavelength and RCS. RCS of an object will exhibit increase when exposed to lower frequency, until the point is reached where the wavelength is far too big to cause any resonance effect. Thus the RCS will fall sharply. The rate of RCS increase is depending on shape where wedge shaped object, for typical aircraft would exhibit wavelength dependency in their RCS. while conical object, consistent with ballistic missile RV RCS increase would exhibit squared wavelength dependency.

              Sounds like they got a story of a missile intercept and then applied parts of the brochure specification liberally.

                Tass basically referencing China's SRBM and now referring a 2nd test that at an aircraft was intercepted 250kms. Than seeing the THAADs performance in X-band RCS targets compared to the S-400 is putting me under suspicion that they are setting up a venus fly trap to draw flies(aircrafts) more closer to the system. Russians never announce what targets they have intercepted while the Chinese give ranges for both aircrafts and missiles and of course it can be a brochure specification for both. I am going to keep an eye out if India or Turkey make announcements on their interceptions if possible.

                  Two Russian Su34 collide in the Strait of Tartary in the far east of Russia (close to Japan)

                  • Two Russian Su-34 fighter-bombers collided in mid-air during a training event over the Strait of Tartary near Japan, Russian media reported on Friday.
                  • A rescue helicopter has recovered one pilot while efforts continue to save others.
                  • Russia grounded all Su-34 flights as a result.
                  [...]
                  Following the Friday morning collision, Russia has grounded flights of all Su-34s.
                  It seems one crew managed to eject as reported to TASS. The bombers were performing scheduled flights from the Hurba airfield, located ten miles outside Komsomolsk-on-Amur reported the Express
                  .

                      Janes reporting one plane RTB and two pilots safe. Don't know if this came after the above and is accurate.

                      EDIT:

                      No, sadly we had the latest and more accurate news.

                      From Scramble today (FB):
                      Another Su-34 update

                      We just received additional information concerning the mid-air collision of the Su-34s:

                      Some details changed. Two pilots were found dead in the sea, one rescued crew was a navigator, the fourth pilot is still missing, Rescue services are continuing their search.

                      The whole formation originally consisted of eight aircraft, including multiple Su-34s and possibly also some Su-35s. One aircraft returned after take-off with an engine malfunction. Seven aircraft continued their mission.

                        Two crew members of a Tu-22M3 have died and two more were injured during a hard landing in Russia's Murmansk region, the Russian Defence Ministry said in a statement.

                                    That's a fairly heavy looking landing gear on Okhotnik - you'd think they were going to use it for carrier landings or something...

                                      The gear is so similar to T-50/Su-57 that I'm almost willing to bet they're one and the same. Also gives a good idea of the scale:
