It sounds like you're talking about a dockable surface port though. Starport defenses are significantly more potent than what settlements / bases have.
Ahh ok. Yeah I haven't been doing planetside missions in my ships since I had a hard time with them early on and figured they were gimmicked to try and make you do them in SRV. When I don't do them in an SRV I always do them in the Krait MkII. Later on I did notice that small ones got pretty small but I just figured that even one anti-ship gun still does a ton of damage; might make it doable, but it's still designed for the SRV. I'll keep in mind to take my Viper IV out to do a ++ and see how it goes.
