Defense against ICBM carried weapons

Post by dagbay » Sat Aug 12, 2017 9:43 pm

ICBM missiles are a difficult target to thwart. These missiles are unique in that they must launch with a sufficient speed to escape the strong surface gravity and get above Low Earth Orbit (LEO). With this requirement they need to speed at near escape velocity at the boost phase making any attempt to chase them very much impossible for any interceptor would have to fly much faster and from very close geographic position to have any chance of catching up. Atmospheric turbulence in the area of the speeding rocket makes it impractical to use Laser interception. During their 2nd stage boost the ICBM fly in space and are susceptible to Energy interception with Laser or Electromagnetics but those need sunlight to charge and have limited capability to operate when they transition into the night phase. Projectile weapons have limited range and require a very large and dense array of attack satellites currently not feasible. In the final re-entry phase ICBM falls pretty much straight down as a rock gathering speed as it plummets toward the surface of the earth. At this point their trajectory is clear assuming they were detected and tracked so interception seems simple but their extreme speeds in excess of Mach 8, and the fact that they are already pretty much above the target make the interception hard or less effective. In case of interception over the target it is likely that radioactive fragments will be spread over the target area - much better than an exploded weapon but far from ideal.

Currently there is no proven defense as far as available public information and few countries have a capability of such defense with the USA not one of those.

This has already been done from a ship at sea to take down a satellite traveling at 17,000 miles per hour



The THAAD Missile system on Guam is 15 for 15 in test shoot downs of missiles.

Impressive, Not quite the same as shooting down a random missile at much higher altitude but impressive anyway.
As for THAAD - never tested against an ICBM - its kill range is insufficient if launched from the target of a nuclear head.

This was a shoot down of a satellite at 62 miles in altitude (Intentionally to limit orbital debris) traveling at 17,000 miles per hour The US Minute man missiles top speed is around 15,000 mph This was a THAAD shoot down with a sea based SM-3 missile.

The only reason that the NK missiles went to 1,700 miles in altitude is that the North Koreans wanted a full burn test without traveling so far across the planet. It only went 580 miles down range. Had gone much far enough to hit the US it would not have gone any where near that high
