Put it just before the reveal in your edit, letting it build the moment, then follow it with a Vine Boom as the craft is shown and a Pew Pew when the action starts. That order keeps the arrival, the impact and the fight in one clear sequence.

This ten-second effect recreates the hum and sweep of an alien spaceship passing overhead, with a deep electronic drone that rises, hovers and fades like a craft moving across the sky. It feels eerie and otherworldly, turning an ordinary scene into something strange and watchful, and it works best when the listener is meant to sense an arrival before seeing anything.
