MG23 :
And pointless now there are a couple more systems that will work just as well as GPS for targeting bombs.
True but think how many last generation GPS dependent US manufactured weapons were given freely to or "taken" by now hostile forces . Think Afghanistan, Iran, Iraq Syria, Libya, African rebel groups of all kind , etc...
I read even that recently quite a few last generation US tanks given to Iraq forces have now been taken over by ISIS, and that the same models are fighting each other in Faluja.
If you were a US military and someone was targeting your forces with one of those and you had a possibility to switch their precision off , would not you do it ?
GPS was primarily a military guidance system ( just like ORAN-C was) they allow civilians to use it but things like IT clocks synchronization of Embraer Yaw dampers was not what they had in mind when designing it.
Why do you think we Europeans spend billions developing Galileo ?
