After 45 years of a conventional start game I finally got a propulsion scientist. Perfect timing too, mineral shortages on Earth are forcing me to expand and consider extra-solar colonies. Unfortunately, I have no military so any exploration is going to be risky.
What should I build for a low-tech starting force? I have no missile scientists, but my best scientist is specialized in energy weapons with a 45% bonus. He's also old and sickly and liable to drop dead at a moments notice.
I'm thinking of using swarms of meson-armed fighters with a few large laser warships. They will be mainly used for jump point defence as I can't see many other ways to engage a reasonably advanced NPR without massive casualty's, given the technology I have to work with.
At low tech it is difficult to design decent beam warships. The primary limiting factor is speed, you need to be able to get into range and then maintain that range. You may need to dedicate as much as 60% of your tonnage to engines to reach a decent speed at low tech levels. If you are going to be using beam weapons then pick one and stick with it rather than branching out. Mesons may be your best bet as they ignore shields and armour. Don't forget to get the first few levels of capacitor tech as well to bring your recharge times down.
If you have to expand beyond sol at your tech level, heres what I'd do in such a situation.
Jump through a cheap scout, just engine and thermal + mid sized active sensor.
Assuming you don't get pounced on immediately, jump through another couple of scouts and send them to each planet/sizeable moon in the system.
Assuming you find no contacts, jump through one or more geosurveyors and start surveying the planets/major moons.
If you find sufficient minerals, start up mining efforts.
If you don't find sufficient reserves then repeat the process with the next system.
If at any point you encounter contacts, If you are a safe distance away flee through the jump point, otherwise sacrifice that ship so that they don't observe you transiting, if they do see you do so they are more likely to follow.
