    Yes, unlike Zircon, Sarmat, Iskander, Khinzhal, Avangard, Poseidon, Burevestnik, Persevet, S-500, T-14, MiG-31, 1144 Orlan etc etc etc  

    It was a joke but still I'm really glad you got pissed off specifically Razz

    Relax and give it time

    If Russia ever builds it's own version you will learn to love it and regularly creampie yourself every time you see a photo lol1

    Yeah. I realise that, and I was agreeing with you... Suspect

    You seem a little... sensitive... these days? You need to work on that fragility... Razz

    Oh yeah totally

    That's what happened lol1

    Nice Hail Mary attempt though, wasted effort but still...

That doesn't really matter however, as after all, the Pentagram has never seen a "weapon" system it doesn't like and want and need...

    There are two theories. One is the official narrative that the X-37 is a robotic space laboratory used to test components in space. The other is that the X-37 is used to inspect or spy on existing satellites.

    Russia has already been testing the satellite inspector for many years:D

    The most important spec of the X-37 is its capability to change orbits unexpectedly, as during perihelion it enter the atmosphere, and change orbital plane randomly.


    Means the X-37 is a very capable orbital nuclear bomber, and its require extreme ammount of work from the Russian / chinese space forces to follow its path.


    It can enter areas unexpectedly, so it is not like the other spy satelites that are easy to forecast,and prepare ,like moving into the hangar the prototypes.

    Nope, it has little more orbital agility than any other satellite equipped with a re-startable engine bus (some claim that it can use aerobraking in elliptical orbits to adjust its orbit, but that just consumes orbital energy so its hardly much of an advantage).  While its plausible that it can carry a nuke payload, in this day and age I don't think its feasible to carry out a sneak attack as a decapitation strike.   Given that it requires a conventional launcher such as Atlas V to be put into orbit (as opposed to solid-fuelled ICBM conversions) it will never be orbited in any significant numbers.

    No, I think this vehicle is a solution looking for a problem.

    The Russians accurately track and log objects in orbit down to the size of paint chips... an object the size of the X-37 would be no problem at all to keep track of.

    Objects collide and effect the orbits of other things all the time so the actual task of tracking most objects is not trivial, but adding an X-37 to the mix wont be a problem either.

    Part of Russian radar-based space tracking would be establishing orbital parameters for all visible objects, then when they pass out of radar coverage, they extrapolate the orbit and accurately predict their reappearance (the methodology will include modelling of atmospheric drag for those object that have a low periapsis). Objects are re-acquired when they return to coverage and any objects that differ from their expected orbital trajectory will be flagged by exception. Objects that were launched on military missions (such as an X-37) with the ability to change orbits will be priority targets.

    Modern computer networks allow such a process to be fully automated, with human operators at Space Defense centers being alerted on a by-exception basis. The result is that the idea that a satellite with a modest propulsion package can change orbit to such a degree within a short space of time in order to evade orbital tracking isn't really feasible, especially a reusable system that must conserve a significant amount of fuel so that it can perform in re-entry burn at the end of mission.

    And agreements with other countries to place space tracking bases on their territory can remove some blind spots too, and make it more accurate all of the time...

    About Russian optical reconnaissance satellites, etc.In this regard, they need much more optical and radar reconnaissance satellites.

    The model in the video looks close to this thing, a space drone from a few years ago.

    Just copy pasting info from paralay forum. it doesnt hurt to check the brother forum sometimes.

    https://rg.ru/


    The multifunctional radar "Don-2N" - the central and most complex element of

    the Russian missile defense system - has been modernized and is being prepared for testing. The performance of the computer system has increased by four orders of magnitude, its size has decreased by four times.

    "The modernization of the receiving and transmitting parts of the Don-2N radar is nearing completion, the installation and adjustment of new equipment is continuing.Work has been completed on the manufacture and installation of the modernized command and computing station," Major General Sergey Grabchuk, commander of the missile defense unit, told Krasnaya Zvezda.

    The don command post runs on a new computer system, the Elbrus-90S, with a capacity of about 100 billion operations per second. According to open sources, the former Elbrus-2, which occupied a whole floor in the cyclopean radar building, could perform no more than 12.5 million operations.

    - The area occupied by the equipment will be reduced by 4 times, and the power consumption - by 40. Due to a significant reduction in the number of blocks and cells, the reliability and maintainability of the complex will be significantly improved. Due to multiple reservations, the time to restore the combat readiness of the Elbrus-90S will decrease," the general continued.

    The main task of the Don-2N is to detect, track, select and calculate the trajectories of ballistic targets, as well as to direct anti-missile missiles to them. Phased antenna arrays on the edges of the truncated pyramid, in which the station is enclosed, scan the airspace and near space for 4,000 kilometers in azimuth and 40 thousand km in height. They are able to distinguish an object the size of a tennis ball.

    The starting positions of anti-missile missiles have also been modernized.

    Since Elbrus-90S is a family of SPARC processors, i am guessing that they will be using R1000 model, which is the last one from the family.

    This sounds like old news though. I heard similar reports years back.
