The minefield consumable calls another group of planes which near-immediately drop the field. I've not seen those planes be shot down, so it's easiest to just see it as a delivery animation.
Since the Concord Bridge's bombers are the only planes that can deploy a minefield, it's worth paying attention to what the bombers do via the minimap once you see that bombers are in use.
If they use the consumable, the field is marked on the minimap as soon as it's deployed. It has a 40 second arming-time, as well.
