    I work with the delta v's "leaked" in the Salman video for my analysis. Real calculation. Dead scrap, it did its purpose of delivering 2500m/s delta v.

    Yes: S-350 But reason is not counter-VLO but over horizon counter-CM There is more to it. Russians are absolute fans of PESA solutions in engagement radars but for the S-500 they swiched. It seems to be about very fast target tracking, because power and cost wise PESA are superior and the gain...

    Iranian Space program

    The third stage had to provide over 2500m/s delta v. So from that 900kg Salman lifts 800-850kg must be spend on the thrid stage and all the equipment. What remains is 50kg with a large error margin of +100kg or -20kg. 50kg sounds realistic. That Peter Pry is far off with his numbers.

    It will look like this: This should be a old mock-up of what the Saman+kickstage should have looked. As for payload estimation: Depends on miniaturization level If guidance and batteries weight just 50kg total, payload fairing just 50kg, and cold gas thruster assembly under 50kg... then yes...

    Brugge is not far off and both of our analysis is not just based on guess. He has about the same results as I on many points. His payload estimate is too low because he estimated a 150kg fairing/shroud which is too heavy for this diameter. The way to analyse it, is to look at the delta v Salman...

    Well my constructive wave interference theory had been refuted once high resolution images became available. These are access hatches as the sides of the X-band engagement radar. They may house a SLC antenna but I tend to fast access to the cooling system maintenance. The mystery remains why...

    Iranian Space program

    Its a quite large 800-850kg third stage with 6 thrusters. Not a Arash-24, 240kg small kick motor.

    Possibly but not certainly. Israel lacks size to test a 400km BM, hence they are forced to do it at sea. So this doesn't mean Lora has terminal tracking.

    Sejil is a special purpose asset in Irans missile arsenal. As two stage and limited lifetime weapon, it is the most expensive missile Iran has. It has been serial produced since long time but not in the numbers of Ghadr. Khorramshahr replaces the payload of 3 Ghadrs. Hence even if its...

    I recommend everyone interested on what Salman stage means technologically for Iran to fully read this article, even if it is about the unrelated Chinese DF-31: https://patarames.blogspot.com/2020/05/the-df-31-chinas-technological-path-to.html It gives the necessary understanding about the...

    Its the launch control of the TEL. The crew always leaves the TEL to safe distance since there is always the risk of malfunction or attack.

    Other than there is no proof such a compact system is feasible, I guess Irans reasoning would be "shell cant be guided due to high g loads, so forget about it for now" It sounds attractive as a brute force terror weapon, yes. But maybe capturing an airbase is a more attractive objective than...

    Of course it would be magnitudes cheaper if no novel 350g rated guidance system is used. Irans missile force is designed to be cost effective but it is still a high priority target system. Foremost used to suppress operation of enemy airpower, you cant use BMs cost effectively at lower tactical...

    Key problem would be guidance electronics/systems that survive the ~350g acceleration loads. Unguided and it may be of no useful tactical value. It clearly show that the U.S is aware that "enemy A2/AD" menace cant be well handled by its conventional airpower concept. The plan would be to use a...

    U.S. Will Not Let Iran Buy Arms When U.N. Embargo Ends: Pompeo

    Irans missile war would be "shock and awe". Wave after wave, with each wave getting stronger until the enemy gives up. - Tomahawk is much less survivable than a BM and the failure rate of a mature BM is <10%. The systems that want to intercept it are few and expensive, while CMs are handled...

    Friendly Fire Incident Or a major plot?

    That's the risk an over horizon autonomous AshM brings. Only a complex satcom based system could help here... and of course... never launch it when anything friendly is close to it.

    U.S. Will Not Let Iran Buy Arms When U.N. Embargo Ends: Pompeo

    Missile warfare means no frontlines, neither ground, nor sea, nor air defense. The idea is to hit the enemy at any time and any space. No safe areas behind the frontlines, no safe zones were defense systems protect. This kind of high intensity warfare ends within a week and paralyzes the enemy...

    U.S. Will Not Let Iran Buy Arms When U.N. Embargo Ends: Pompeo

    Pentagon numbers of Iranian BMs are for their home consumption. Anyone who wants to get an idea how large the arsenal is, can check Iranian missile bases that are not very difficult to find and identify. Based on the size and number of bases and units it's clear that 2500 is a joke.
