Reload rate 6 is huge, it gives you 5s reload size 1 launchers and 30s reload size 6 launchers. In fact, you pretty much don't need reload tech after that for your main ships - just for oversized missiles or for miniaturised launchers.
We've also just completed a new level of Jump Drive efficiency, allowing us (for example) to reduce the size of our jump drives for 20,000-tonners by 17 hull squares (850 tons). That frees up quite a bit of displacement for other purposes, such as additional Magazine storage. Four more months and we can design new Gauss PD systems.
... looks like another Fleet rebuild coming up, although one might argue that I should wait for the next level of Power and Engine tech to finish. It's already under study.
EDIT:
In addition to gaining us more wrecks to scrounge and another xenoarcheological site to excavate, our conquest of the Gliese 250 system has given us access to another uninhabitable but mineral-rich world. Not quite as rich as Moria, but it has eight of the eleven trans-newtonian elements, in concentrations of 80% and up.
