    I was talking to a Vietnam war vet a few months ago. He was serving at the tail end of the conflict. This Retired Marine served on an artillery battalion, he told me that each battalion had at least one Davy Crockett warhead with them. As he said it was just incase China wanted to "dance" with them.

    A couple things. Just the sonic boom and over pressure from a meteorite over Russia a few years ago blew out windows and damaged buildings, injuring and even killing a few. Also, the rod would be covered in carbon-carbon, just as our nuclear MERVS are, which protects the object from reentry heat. Lastly, nukes typically detonate at some altitude and this thing would actually impact into the ground. Not sure what effect that would have, but a meteorite again over Russia leveled a huge swath of forest about 100 years ago without actually impacting the ground.

      It wouldn’t have to be covered in carbon-carbon because the melting point is above that of the reentry heat. Tungsten can naturally resist the high temperatures, unlike nukes with lower heat tolerance.

    I believe this weapon would be more suited to penetrating deep and destroying a underground base. Or other type of fortified structure underground. It would be much better to somehow refine the tungsten on the moon or elsewhere though. Super expensive to get that much tungsten in the first place and even more to ship it from earth into space. Would love to know what rhe space force is playing with up there.

    You left out the possibility of gaining the desired kinetic force needed for a larger radius of destruction through means of utilizing a large (spring triggered launch). If you were to add in the force you may get from a very large spring inside the rod containment device then you should be able to gain a significant amount of kinetic force adding to the overall total destruction right...??

    • @nameredacted3095
      @nameredacted3095 3 ปีที่แล้ว +4

      As for spring integrity/tension retaining issues that may arise due to cold snap, I would say try using a Titanium spring. If you also insulated the barrel (made of aluminum) with a very thin layer of space blanket material, (depositing vaporized aluminum onto plastic,) then I think we may have reached the (plausible) range of capability of a "space based spring fired tungsten rod..." *Food for thought* I hope to see an updated video talking about these possibilities. Much love.

    Actually the kinetic factor. You could build a graph that would connect the area of ​​destruction with the mass of the bomb, taking into account the loss of kinetic energy at different volumetric area ratios, and then we would get the optimal size values this weapon. speeds. I assumed I would go to extremes - ordinary light bombs of 200-500 kg that lose almost all speed. It can be assumed that the other extreme is to drop a 150 ton bomb, which obviously will not lose much in speed. If we make the bombs smaller, we hit more objects and a larger area. If we make the bombs bigger, we save more kinetic energy but concentrate the impact on a small area, which is ineffective.

    You did not account for the air density at various altitudes and wind pressures at various altitudes. As the higher altitudes have a lower density of air pressures. Which reduces the induced drag at altitudes. The kenetic energy is close to a 50kt tsar bomba.

Corrections on ballistic trajectory are made by internal guidance system (ballistic calculator) which has number of sensor consisted of GPS, INS and THERCOM. It is true that on some older ICBM-s warheads go on free fall once separated from boosters but that is only because of shire power of nuclear weapons, even if they miss couple hundreds of meters it would make no difference, the target would still be destroyed 100%.

    As a result, I assume that the optimal size ratio for a space weapon is something close to a mass of several tons, containing 1/3 1/2 explosives and a significant amount of ready-made large, up to a kilogram, damaging metal elements. Such a bomb should fly to the point while maintaining a maximum speed of up to 3-4 km per second (if more is better) and explode at the final stage of the trajectory creating a rain of striking elements equivalent in armor penetration to the de.wikipedia.org/wiki/Projektilbildende_Ladung (1000+ for one bomb). When calculating that one impact core per square of 3 * 3 meters is guaranteed to destroy all the equipment, we will get an area of ​​​​destruction of the order of 9000 square meters in combination with an explosion of 2.5 tons of TNT. A circle with a diameter of about 100 meters will be almost completely destroyed. Tanks, concrete defense structures, manpower will be hit by a shock wave. At the same time, starship spacex will be able to deliver 20-20 such strikes. That is, destroy everything in a diameter of 400+ meters, which is comparable to a tactical nuclear strike

    I think kinetic orbital weapons are a little misunderstood. Let's take a look at Starship SpaceX. It is capable of carrying 100-150 tons of bombs (aircraft, 50 or less). It can stay in the air for months (the plane is a little more than a day). It is higher than any air defense except for anti-satellite missiles. His preparation time is 24 hours, b2 51 hours. He can strike in the crown of 10 minutes 2 hours in any part of the world. These are the primary advantages of orbital weapons kinetic energy are secondary.

    This is a really good video. I crunched out some of the math before this video at times, and always came up with some number that was way off from the kiloton range as well.
    And even though it's technically very cool, there's still a lot of problems; how do you get the rod on target? It's hard enough trying to get a round on target 30 kilometers away with an artillery shell.
    And sure, you could put a guidance package on it, but how are you gonna guide this thing to the target when it's travelling at 7 kilometers a second, through the atmosphere? That thing is gonna get mighty hot, and maybe the tungsten can take it, but I doubt the electronics will, and what's the CEP gonna be when that thing is fried and it's falling down on its own?
    At least at the moment, kinetic bombardment is...kind of too expensive, for pretty measly results.

    The one thing that doesn't.make sense to me is the drop. If the satellite remains in orbit it seems the rod would too if it was just released. I'm not a physicist, but wouldn't this need propulsion to get it moving away from the satellite? Or would it drop because of its density?

    Let's get back to starship spaceix. Suppose it carries conventional glide bombs or their orbital equivalent. JDAM weighs 200+ kg. Suppose the orbital analogue of the bullet weighs 300 or even 500 kg. Suppose it loses most of its speed and falls at a speed of 1-2 km per second at the end of the flight. It's still 200-500 guided bombs per hour to anywhere in the world. Such bombs cost from 100 thousand dollars. So the volley is worth at least 20 million by itself. If we assume that the starship will fly for a price ten times higher than the declared one - 15 million, we still get X2 of the cost. That is, for increasing the price from 100000 apiece to 200000 apiece, we get the opportunity to hit anywhere in the world in an hou

    A smaller and lighter Version would be a good Warship destroyer, mainly because all Anti Missile Systems will fail against it. Maybe a Rod of 1.0-1.5m length and a diameter of 10-15 cm will do it. The Mass of the Rod i guess up to 600-800kg. Then use if necessary a little more alltitude, lets say 500km and maybe a buster like a rocket to max. speed so Mass and all other can be more limited. Just think about it, every Vessel sunk with just one shot, no way to defend.

      While I am all but certain that we have some of these in orbit, I doubt we have many. We'd need hundreds to totally neutralize China's nuclear cabability in a single strike (assuming our strike is non-nuclear).
