A launch every 10 seconds is pretty quick, but not too special. Then it began to look like I might be able swing one per second with a bit of extra work, which is more like ludicrous speed. But what the heck, gotta have something to aim for, right?
Then, after building a bit, I realized my math was off, failing to fully account for module production bonuses. It would be more like THREE launches per second. What the heck! Go straight to plaid!
I thought I'd post some pics as I go along to get some feedback.
Currently the only robots on the map are 10 logistics bots to service character slots, and 10 constructors in a personal roboport to build blueprints. I don't really count those against a no-bot challenge.
UPDATE: Success! Averaging about 1900 rockets every 10 minutes
288 silos fed by 73 belts
Limiting factor right now seems to be the logic boards going to the control units. Might be able to bump it to 312 or 336 silos with some minor upgrades.
Instead of a bunch of screenshots, I uploaded a Factorio Maps render: http://theharms.org/misc/factorio-pics/plaid-rockets/
40 minutes worth of launch stats
10-minute production stats
10-hour production stats
a lot of rockets
