For your apparent tech level:
-Your missiles... what the FUCK!? Even a STR-16 warhead would be overkill at your level of advancement. And you pay for the oversized WH with terrible range, terrible speed, and terrible accuracy.
-FC and AS are painfully short-ranged, even for such a short range missile.
-Thermal sensor is too small to be very useful.
-2 armor layers is nothing at all compared to every single weapon you'll encounter.
-A single Delta shield is meaningless; 2 points of shield will drop after a single hit from just about anything but a TL1-2 laser or a single AMM.
-Another part of the price of having ASMs that are TOO FUCKING BIG is that you can't manage anything approaching a useful salvo (I typically have at least four times that many launchers on a ship half the tonnage, at a comparable level of tech), and that you can hardly carry any reloads even with far too much of your ship composed of magazine space.
-You're evidently playing on pre-6.x. 76b km is fairly short ranged, even for a ship that small.
-You've also got poor speed for your drive tech. I'd be inclined to blame the massive fucking magazine. Seriously, I've had 30k ton heavy cruisers with the same sort of magazine space. The main difference being that the same amount of magazine space would carry a bit over 200 ASMs if they're a reasonable size.
-You have no PD. With 2 armor and 2 points of shield, the first thing that hits one of those is going to wreck it.
But yeah. Most of the issues stem from the massively oversized missiles. It'd be one thing if that was supposed to be a planetary bombardment ship, but...
