[Star Wars] I'm a pretty old Imperial/First Order engineer. I've now seen two Death Stars, one planet-sized superweapon, and a Dreadnought supercarrier destroyed by small attack fighters our turbolasers couldn't touch. Can we PLEASE start installing point defense systems?

I would think we could start utilizing weapon systems that, I don't know, *actually work against the tactics our enemies have been using for decades now*.

We don't even need to get rid of the turbolasers, even.

And the first person to say the words hubris, pride, or overconfidence gets vented out into space. Those excuses only work two times at most.

The turbo lasers you are referring to are the point defense system. The Death Star in particular was covered with them. Unfortunately, the speed and maneuverability of small fighters makes them extremely difficult to defend against. 

Edit: Basically you’ll see this same problem in the future with Earth navies. Their capital ships have little effective defenses against enemy fighters besides just employing enemy fighters of their own. 

Other things to consider:

* The principle problem with the Death Star was the sabotage done by its principal engineer. They didn’t have more robust defenses because there was no reason to think the Death Star could so easily be compromised. 

* The Second Death Star was defended against small fighters. It had a massive protective shield that prevented them from penetrating inside. It was only after their defenses were sabotaged that they could launch an attack. The same thing can be said for Starkiller base. 

* The dreadnaut attack was cause by General Hux’s incompetence. This is a simple case of garbage in, garbage out or an ~~ID10~~ ID10T error. You can’t expect a ship’s defenses to be adequate when the brass is woefully dumb.
