Jenny has a fixed size 2 beam on her Courier, and she can use it to completely take out ground defenses (including skimmers). It's basically like aiming a laser pointer
That said, dumbfire missiles pack a massive punch for a size 1 hard point. I've used them to great effect on large targets when flying small ships like the iEagle (once you get the shields down). And, missiles are fun!
I know this first part is pretty off topic and i bang on about the X series a lot, BUT if you like missiles, they're extremely varied and fun to use in the series in really any of X's ships, while in particular Missile Frigates (which were introduced in Terran Conflict) which aside from some of them, though not all of them having defensive turrets, they ONLY fire missiles as primary ammo and given a big enough supply (and usually after taking
quite a while and many millions in build their missiles in often dedicated factory complexes), they can obliterate entire sectors and are basically an "I Win!" button, with a full cargo hold (with or without transport ships sitting on standby with MORE missiles...
A similar thing that can
absolutely destroy even the biggest enemy targets are launching hundreds if not thousands of fighter drones, or a dozen or more lasertowers...
Such things are enough to make you shout "What Fun!", like Fawkes in Fallout 3

Anyway back to the topic of missiles in this game, while i haven't tried dumbfire missiles, as i prefer homing missiles, even given the extra damage dumbfire ones offer.
I still love using them in this game (even given their limitations compared to the X series missiles, only giving us two choices of missiles and making us fire them from hardpoints, when missiles in X are stored in your cargo bay and fire independently of your other main weapons) and i use at least one launcher on ships with small turrets and even put small ones in medium turrets sometimes, as i'm 90% sure class 2 missile launchers don't fire more powerful missiles than class one launchers (MAYBE class three missiles are more powerful), but only carry more missiles, while needing a fair bit more power to run and costing a fair bit more too... still missiles are always great
