He seems to be referring to a subsection of the military research screen. While research amounts are small individually, usually a 5% bonus per level, they do indeed add up as you progress through the game. Even limiting yourself to level 1 hull and armor bonuses gives you a bonus that gets better and better as you build more ships. Research at the lower levels is useful when a game gets going and you have income rates that allow you to recoup resources spent on research in a minute or two. Don't spam research though, its best to have more ships first.
Yes sorry I should have been clearer. (

Like I said I am pretty new so I am just getting into it. I was indeed referring to the sub branch of the military tree for TEC entitled “Structural Subsystems”. The other two under that tab are “Ballistics and Rocketry” and “Experimental Design”. I have not played any of the other races so I don’t know if they are the same are not.
Thanks for the heads-up about the above. I wondered if researching into that to early was the right thing to do vs. build ships. Though I took to heart, stated above, that at the beginning of a game it can be a bargain as well. As I said I have not played the others races but I get the impression from other posts that the TEC is good at making big fleets. I read one guy who said you should “spam” ships as TEC. I don’t know if that is canon or not but that is the kind of thing I read.
Thanks, just wanted some insight.
