Tempest

The Protoss Tempest is a powerful air unit in Starcraft II. Like the Carrier from the the original StarCraft and Brood War, the Carrier has powerful shields and, while having no armarments of its own, carries a number of small fighter-type drones that launch, surround and swarm a target, doing little damage individually but significant damage when combined whilst maneuvering rapidly, making it difficult to destroy. The Tempest is strong against ground targets, but is ill-equipped to handle air-to-air encounters.
