Remember after desert storm and the Iraq invasion we heard about 80% guided munitions success rates after a shock and awe event only to find out later it was 20%? Can we hit the barn door?

The claim of 97% reliability for the U.S.’s anti-missile defenses is being challenged by Cirincione and others, who argue that the United States can only “shoot down some…missiles some of the time.” They make a number of arguments that are quite convincing, even to a layman who has no understanding of the physics involved. I will try to keep it simple. First of all, an anti-missile interceptor must hit its target head on or nearly so and it must either actually strike the target or explode its own warhead at a close enough distance to be effective. Both objectives are difficult to achieve. An Intercontinental Ballistic Missile (ICBM) travels at 5,000 meters per second. By way of comparison a bullet fired from a rifle travels at about one fifth that speed. Imagine two men with rifles standing a mile apart and firing their weapons in an attempt to have the bullets meet head on. Multiply the speed by five if one is referring to missiles, not bullets. Even using the finest radars and sensors as well as the most advanced guidance technologies, the variables involved make it much more likely that there will be a miss than a hit. Cirincione observes that “…the only way to hit a bullet is if the bullet cooperates.” Read the rest of this entry »
