How do I get probes?

Ship Yard (Level 3)
Combustion Engine (Level 3)
Espionage Technology (Level 2)
If you click Technologies it has a list of what is required for what, building, research, defense, and ship.

So with the probes, there are 2 kinds of espionage right? The kind where it sends just 1 probe for a "lite scan", and then the other Espionage is the one that's sent with other fleet ships under the attack option for a more "full scan"right? ....Cause when I click the espionage icon/button it automatically sends just 1 probe, the attack option is the only way to send more than 1....

You can change the number of probes to be sent in the Options.

You never want to send other ships along with your probes for espionage missions. You run the risk of losing all of your ships that way.

Ahhhh.... cool. 8) Thank you!
