[X] Recommend a six-ship run of the Stingray. (-30 Industry) (+1.3 Industry/Year) [Ends 2155]
Honestly, my reason for recommending this - even aside from the rising tensions with and between multiple neighboring powers - is that Warp 4.9 might seem fast, but it's still weeks between even Earth and it's nearest colony. And that response lag means that colony security is best provided by having at least one ship on station at any given time. With the three ship run, we might be able to get a single ship at every colony, sure - but that's only a single ship, and one bit of bad luck could leave a colony devoid of defenses for weeks on end, to say nothing of crew rest, rotation, or maintenance.
If we had the industry for it, I'd honestly be pushing for an even larger production run, to try and get 3 ships for each of Earth's colonies and Earth itself - that way, you can have one deployed, one working up for deployment, and one off the line on maintenance/repair/refit at any given time (this is part of why the real life US Navy has so many CVNs, and why just looking at ship numbers isn't a good metric for determining how strong a navy is without taking other factors into account).
