Multiple Countermeasures Available to Defeat Space-Based Missile Defense Systems
Similarly, a number of measures could be developed to counter a space-based interceptor. One countermeasure would be to develop technology to boost rockets faster, rendering important boost-phase defenses impotent. China has already made steps in this direction by developing solid-fuel ICBMs that burn faster than its previous liquid-fueled missiles. If the spaced-based laser were to be revived, specific countermeasures could be developed. The countermeasures could include rotating the missile to distribute the laser energy over a wide area, thus preventing the missile from being damaged, or protecting the vulnerable parts of the ICBM with reflective or ablative coatings. Moreover, the attacker could simultaneously launch several ICBMs or an ICBM with some theater or tactical ballistic missiles used as decoys from a compact area to overwhelm space-based weapon systems.
