Greetings fellow hackers.
I have finally completed the mission which was assigned for me few months ago. I have collected all scans and organized them to datasheets. Data was gathered using fake identifiers and civilian shuttle.
Data what I collected shows that laser weapons are most used in Liberty with Tachyon and Particle holding second place. That makes graviton shields optimal choice for our fleet, I do know that that shield type is weak against Particle weapons but its still best choice as molecular shields are weak against tachyon guns which have almost same usage level than Particle, Positron shields are not good either as they are bad against laser weapons. This is based on 24 unique fighter/freighter scans in Liberty, it doesn't contain all 25 because one ship used only pulse/direct damage type weapons.
Here is final statics in datasheet and graphical version of it:
