I'm still quite a newb at this, so I need some constructive criticism on my designs. Specifically, a beam platform designed to guard a JP.
You don't need the THermal or EM sensors, unless you're worried about ships coming up from behind and not through the JP. You DO need an active sensor, or you won't be able to shoot at all.
Ships coming through the jump point will be deaf, dumb & blind, but they can move at full speed immediately after emerging, so they'll likely run (possibly away from you) in a straight line directly away from the jump point. You might want faster recharge, longer range, or both. Balancing the demands of energy weapons in a fixed amount of hull space is one of the toughest things in Aurora.
I wouldn't bother putting shields on a JP base, since you won't have the time to raise them, and keeping them on burns fuel. Which means you should install a fuel tank or remove the shields.
Expect your base to have to fight three enemy ships simultaneously, since that's the default squadron size. Of course, that's generally two combat ships and a jump tender, so you might be fine concentrating your fire on the warships and hoping to mop up the jumpship afterwards.
