Here are all the versions of the Hornet I have done (TL-13 high automation, TL-15 no automation, TL-15 high automation, and because I could, TL-16 high automation to see what Vincennes might make for themselves). Dropping it to TL-13 meant losing the range advantage for the meson bay, dropping the armor to crystaliron and losing a few points of armor, dropping the sensors to improved, and thrust going down to 7. That stung and the Hornet might not be practical at that tech level.
I was able to upgrade the countermeasures suite to a military countermeasures suite for TL-15 versions, so that adds an additional +2 to jam/EW (total +6) from the original designs, making them even more dangerous as they will be harder to hit.
I added a TL-15 electronic warfare version with 3 sensor arrays, 3 enhanced signal processing suites, 3 military countermeasures suites, and 37 additional sensor stations to perform a total of 38 distinct sensor actions (like jamming). It has no offensive weapons at all, but does have 10 type III-L point defense units. It there are 1 in 10 of these, that boosts the defensive firepower by almost 50% but only costs 10% of the offensive firepower. The additional sensor stations grant the swarm an almost 300% increase in the ability to jam. I could probably add a few additional sensor stations to the regular units. I'll look.
The TL-16 version gets thrust 10, a superior sensor suite, an advanced countermeasure suite with an additional +2 to jam/EW (total +8), and molecular bonded armor at 30. The meson bay got the high yield advantage added, making for more damage. There were other tweaks for the higher tech level.
My advice is not to attack Vincennes. Enjoy.
