Rods From GOD
or Jerry Pournelle’s THOR. Same thing.
Maybe the X-37B is full of ‘em.
I'm astounded we haven't seen more conjecture on the subject in the news.
A 20ft rod, 2ft in diameter...with guidance...could hit a spot with a 5ft CEP at 7500 MPH. The resulting explosion would resemble a small nuke and could penetrate 300ft of rock/concrete.
Without a trace.
No radar signature, no fallout, no explosive scrap or shrapnel.
Smaller rods could be deployed against individual human targets. For instance, a 5ft rod which was but 1inch in diameter would take out a big house and kill everyone in it.
A country with good space lift could put a BUNCH of those up pretty quickly.
Every strike untraceable.
