One mechanics question, and an advice question:
First, is there any way to refill box launchers without docking? I was considering a "VLS" type design (All box launchers, no magazines similar in concept to modern US missile cruisers) for a cruiser, but it didn't seem worthwhile on ships small enough to fit anywhere reasonable.
As for advice:
I'm about to restart again (after making yet another stupid mistake, this time with bad engine efficiency sucking down all my fuel), and wanted a bit of advice first. Previously, my missile size system was 1:3:5:10:25:50 (Light Fighter/antimissile:Frigate/Heavy fighter: Cruiser : Heavy Cruiser : Capital Ship : System Defense, with the latter two never getting introduced due to early failure). I also had a "torpedo" class that would have broken down 4:9:24, which were short-range heavy warhead weapons intended for use in mines (hence the smaller size, you'd simply wrap them in 1MSP of sensor and reactor, then fire them out of the next size tube. Only the smallest size was introduced, and only in the packaged mine form. I had plans to also include missile tubes sized for torpedos on some of my lighter ships in the same style as WWII destroyers and cruisers, and possibly dedicated "torpedo bombers".
A few specific questions:
Should I even bother with the size 3 tube? I can fit a size 5 in the same ships with only moderate levels of reduced size launcher, and once I get to box launchers, fighters can carry size 5 and even 10 missiles easily enough. It might be useful later on as a dedicated long-range intercept missile (against fighters or as an antimissile) size, but I'm more concerned with shipkillers at the moment (outside of the size 1 tube, which will have highly-manueverable antimissles or less agile missiles with larger warheads to hit fighters).
Similarly, are reduced-size launchers a viable choice for a main battery? You can get much heavier salvos off, but the reload penalty seems to be a serious handicap.
Finally, what's the ideal sensor on a missile? I assume that it doesn't need to be that powerful, since (as I understand it) it usually comes into play when an in-flight missile loses the target, so the range will be fairly short, but what's the most space-efficient?
