Not really. I think US has enough technology to make a smart enough auto-pilot which can do such missions completely without human intervention.
Yes, we do.
Also I did not say it could not broadcast data, it surely can but when in very secret mission it would be in a complete radio silence to avoid detection and would store data only to be accessed when it returns to home base.
Wrong. Completely. But we should expect that from you by now.
First...An F-22 can fly and broadcast everything he has: radar, radio communication, navigation queries, whatever...But this does not mean his radar signature is increased. Radar signature is body specific. ElectroMagnetic (EM) emissions signature, to use the word casually, is a
SUMMATION and
COMPOSITE of all those transmissions, including radar body signature.
So let us get that distinction out of the way.
What this mean is that the secrecy of an intelligence/surveillance/reconnaissance (ISR) flight is more about its target than it is about keeping the drone's presence secret. It is an understandably false assumption based upon the words 'secret' and 'stealth' that someone who has no military experience would make. But we at least expect the person to acknowledge his ignorance.
For this event, the US control Afghanistan's airspace and the mission had the drone flying in Afghanistan's airspace looking across the borders into Iran. Since the Taliban is nothing but a bunch of religious nutjobs who can only operate mechanical devices and wishes to remain primitive, what is the need for US to maintain EM restrictions? But that does not mean there are no restrictions, only that those restrictions are
NOT absolute.
If the mission was EM provocative, meaning we want to elicit some kind of EM transmissions from Iran, then of course we want the Iranians to know the drone was there.
If the mission was surveillance, then it may or may not matter if the drone's presence is known by Iran. We may want to know how Iran
RESPOND so we would not care if the drone's presence is known, but if we want to know how Iran
CONDUCT daily activities as normal then of course we would have EM restrictions during the mission. There are great differences in learning responses to stimuli versus ordinary conducts. A knowledge of both would give US valuable insights on how the Iranian military would perform in war.
If the mission was reconnaissance, then of course we would have EM restrictions during the mission.
In all cases, each would be classified as 'secret'. Get it? So stop making baseless assumptions. I would think by now you have learned something about making a fool out of one's self blathering in subjects you know nothing about.
The Iraqi insurgents probably were hacking into earlier models of Predators which are not stealth and even in that case, it was actually Iranians that had trained the Iraqi insurgents to do it.
This has been debunked a long time ago. The Predator's video transmission equipment were not capable of sending secured data. Given appropriate gear, intelligent guesses, and some luck, anyone could have 'hacked' into this feed. But the reality was that no real 'hacking' took place.
