Application of space-based lasers constellations for ballistic missile defense

With the development of space technique, the tactical function of space weapon system becomes more and more important. Through introducing the principle, characteristic and technical parameters of space-based lasers, a constellation of space-based lasers for ballistic missile defense is designed. Then, the campaign capability of different laser constellations for ballistic missile defense is analyzed. The key problems for domestic development of space-based lasers are also put forward.
