Strategically this is huge for the US and NATO. Being able to put orders of magnitude more payload in orbit at a fraction of the cost of the competition is a huge advantage in controlling space. Starlink and starshield are already years ahead of what china and russia has, starship is going to widen that gap even further.
Amen! If it turns out we can’t make humans a multiplanetary species in any reasonable timeframe, at least we can make the last few decades of livable earth climate a friendly atmosphere for US business interests.
Even a nuclear war would have that outcome. Even a KT boundary scale asteroid impact would have that outcome. The rest of the solar system is just hell.
The most expensive part is to support the risk and cost of research & development. Sure, that renders you the first place for a while, but expect others to move easier (and thus faster) after you marked the trail.
To get an inert object through the atmostphere and do real damage it has to be very large. That's a very inefficient way to use mass that you've boosted to orbit, even if it's relatively cheap to get there. So any weaponary they put up there will likely look fairly conventional. The speed of deployment and difficult of intercept would be the game-changer.
Well you answered it yourself, anyone competent can dodge that. It's useful for attacking existing installations, but well, you can do that with any weapon.
Plus it's easier to intercept orbital bombardment since you know where it is ahead of time and have plenty of time to intercept.
it takes few minutes for it to reach target so no it's not easy to intercept also what exactly are you planing to use to intercept a solid tungsten rod with exactly?
But it’s true for any orbital-based weapon that needs to de-orbit for striking. Once it starts retro burn you know it’s going for strike and know where it’s going to strike.
It needs to re-enter, i.e. have the thermal shield, etc. This is what this Starship thing is all about - re-entry is really hard. Regular guide bomb is just going to burn or re-entry into atmosphere.
I've wondered about that. In a series of sci-fi books (the lost fleet series, starting with Dauntless), our intrepid heroes bombard military bases with BFRs. Big fucking rocks. Which are tungsten slugs coated with ceramic I think.
These are fired from light hours away at approximately 0.2 to 0.3 c. I had assumed that something going so fast would just disintegrate if it hit an atmosphere head on? The projectiles are described as "increasing velocity" as they approach, and they strike with gigaton effects. I remember reading an xkcd that showed something traveling so fast in atmosphere would cause huge explosions from air turned into plasma.
Depends on the mass of the object, of course, but at at this speed (i.e. energy) it will become a stream of particles going through atmosphere and vaporizing anything in it’s way.
