I've scanned through the PDF and errata, plus a quick search of this sub-board, and didn't find this. If it's already answered somewhere, my apologies, but please point it out.
Can capital missiles be used for orbit to surface fire on a bearings-only launch? (Rules on pp 100-106)
Say my warship is burning towards a planet. I'm days away from orbit. But I want to soften up the ground for my troops. So, I fire off capital missiles (conventional or nuclear), targeting known military facilities in range of my intended landing zone. Accelerating faster than I am, they reach target a day or two before me. So, when I arrive, things are nicely pre-bombarded.
Conversely, can bearings-only launches be used in surface to orbit fire?
Using the above example, the defenders detected my jump signature and launch a volley or six of missiles to coast along my likely path and activate in staggered locations calculated as my likely points while accelerating at 1G. So, as I burn towards the planet, I might suddenly have to dodge a fast approach by a cloud of White Sharks hoping to crit me before I orbit.
