So, I noticed an oddity with box launchers.
After firing a missile out of one of my box launchers (size 1), I notice that the reload time is displayed on the ship combat tab in the fleet window. The reload time is listed as about 4000 seconds, which by my reckoning is a bit more than an hour. However it takes nearly 12 in-game hours for the launcher to reload and be ready to fire again.
Any idea why this is so?
