The delay starts at launch and is counted in game frames, 15 to the second. Until it runs out, the fuse cannot set the projectile off.

Only a projectile with a ROT above zero has a fuse. On a projectile whose ROT is zero, this setting has no effect.

A shot fired at an aircraft is armed at once, whatever Arm says.

Once armed, the fuse trips when the projectile comes within 64 leptons of the fuse point, height included, or when it is within two cells of the fuse point and moving away from it.

The fuse point is the target’s position at the moment of launch, not the predicted aim point. It does not follow a target that moves afterward.
