What needs to be "borrowed"...

[aramis]

If it's in TTB, and in Starter, is it missing from LBB2 '81, or am I just confused?

CT81 bk2, pr6, p17 has both missile and sand prices & masses

ibid, p32 specifies it launches with the same vector as the launching ship. It also mentions that a launcher has 3 missiles

Yes, but... by physics alone, the missile starts with its own acceleration from the shared vector, since, sitting in the launcher, it's got the same vector as the ship already.

It differs from the ships starting the moment either uses it's thrusters after launch, and launching is itself is a use of thrusters.

Thanks. I'm going to play with that a bit on my own to make sure I understand how the mechanics of this will apply in the game (crunch).
