Re: Vengeance Weapons (Spoilers, maybe)
Phasers are neither sub- or superluminal, but rather have variable speed. Hand phaser beams move very slowly; starship phaser beams move very fast, and often at high warp (because they can explicitly reach targets at warp).
But then the relative velocities between those two ships are quite a bit lower and the phaser beam itself isn't moving all that fast with respect to the ship that fires it or the ship it hits.
