| Oct 1, 2019 at 3:53 | comment | added | cmaster - reinstate monica | @Thucydides No. Explosive Reactive Armor explodes on impact. The 60km/s tungsten rod needs to be destroyed when it's still far, far away from the ship. To be effective, an interceptor needs to hit the impactor when its still a few tens of kilometers away, or the debris cloud will be deadly. Which means, given the probable speed differences, that the interceptor needs to be fired while the impactor is still hundreds of kilometers away. Good luck trying to a) detect the impactor in time, b) aim and fire the interceptor in time, and c) actually hitting the impactor with the interceptor... | |

| Sep 20, 2019 at 19:40 | comment | added | Thucydides | This is essentially Explosive Reactive Armour transposed into a space environment, but because of the difference in scales (speeds are measured in kilometers per second and impact energies are measured in tonnes or kilotonnes of TNT), you need to expand the idea greatly. | |
| Sep 20, 2019 at 15:35 | comment | added | FlyingLemmingSoup | This is actually pretty much my plan already, I was just wondering if I could make any form of passive defense practical. Also, the interceptor round doesn't have to be particularly expensive. It could be fired from a railgun at 2 or 3 km/s for instance, designed to expand out into an umbrella shape after firing. | |
