This technology is very far out—in miles and years. A pair of satellites orbiting several hundred miles above the Earth would serve as a weapons system. One functions as the targeting and communications platform while the other carries numerous tungsten rods—up to 20 feet in length and a foot in diameter—that it can drop on targets with less than 15 minutes’ notice. When instructed from the ground, the targeting satellite commands its partner to drop one of its darts. The guided rods enter the atmosphere, protected by a thermal coating, traveling at 36,000 feet per second—comparable to the speed of a meteor. The result: complete devastation of the target, even if it’s buried deep underground. (The two-platform configuration permits the weapon to be “reloaded” by just launching a new set of rods, rather than replacing the entire system.)

2개의 인공위성으로 이루어진 시스템 (하나는 통신및 목표조정 하나는 발사체)
텅스텐으로 만들어짐
굵기 약 30 cm 길이 600 cm
공격 지시후 15분내 발사가능
속도 약 36000 fps or 약 초속 10.9 km

단점: 지구를 도는데 100분 걸림 (목표 지정후 발사 까지 시간이 걸림)
가격이 비싸다

장점 : ICBM (대륙간 탄도 미사일) 쓰는것보다 훨씬 싸다.
방사능도 없다
충격파를 지하 깊숙이 보낼수 있다.
그래도 ICBM
