"Since the whole-area defense system is rather troublesome, we'll use simple sensors and detection devices for monitoring."
Lyu reminded, "To monitor a planet, at least five surveillance satellites are needed, estimating roughly, we need at least six hundred surveillance satellites. Moreover, if the opponent discovers these satellites, they will certainly adjust their landing points."
Yang Ming turned the chair halfway, continuously calculating at heart.
The cost of six hundred monitoring satellites was one issue, and getting them done in a short period was another.
Even if purchased through international channels, it would take at least half a year.
The current problem was that Wind had a weak foundation, and the New Federation was too aggressive.
The New Federation might bury the insects in a couple of days, and the only thing we could do now was to have warships patrol everywhere.
