Drone swarms are used in target search, [[drone display]]s, and delivery. A drone display commonly uses multiple, lighted drones at night for an artistic display or advertising. A delivery drone swarm in delivery can carry multiple packages to a single destination at a time and overcome a single drone's payload and battery limitations.<ref>{{cite book |last1=Alkouz |first1=Balsam |title=2020 IEEE International Conference on Web Services (ICWS) |last2=Bouguettaya |first2=Athman |last3=Mistry |first3=Sajib |date=Oct 18–24, 2020 |isbn=978-1-7281-8786-0 |pages=441–448 |chapter=Swarm-based Drone-as-a-Service (SDaaS) for Delivery |doi=10.1109/ICWS49710.2020.00065 |arxiv=2005.06952 |s2cid=218628807}}</ref> A drone swarm may undertake different [[Formation flying|flight formations]] to reduce overall energy consumption due to drag forces.<ref>{{cite book |last1=Alkouz |first1=Balsam |title=MobiQuitous 2020 - 17th EAI International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services |last2=Bouguettaya |first2=Athman |date=Dec 7–9, 2020 |isbn=9781450388405 |pages=386–394 |chapter=Formation-based Selection of Drone Swarm Services |doi=10.1145/3448891.3448899 |arxiv=2011.06766 |s2cid=226955877}}</ref>
Drone swarming can also come withintroduce additional control issues connected to human factors and the swarm operator. Examples of this include high cognitive demand and complexity when interacting with multiple drones due to changing attention between different individual drones.<ref>{{cite journal |last1=Hocraffer |first1=Amy |last2=Nam |first2=Chang S. |date=2017 |title=A meta-analysis of human-system interfaces in unmanned aerial vehicle (UAV) swarm management |journal=Applied Ergonomics |volume=58 |pages=66–80 |doi=10.1016/j.apergo.2016.05.011 |pmid=27633199}}</ref><ref>{{cite journal |last1=Lewis |first1=Michael |date=2013 |title=Human Interaction With Multiple Remote Robots |journal=Reviews of Human Factors and Ergonomics |volume=9 |issue=1 |pages=131–174 |doi=10.1177/1557234X13506688}}</ref> Communication between operator and swarm is also a central aspect.<ref>{{cite journal |last1=Kolling |first1=Andreas |last2=Phillip |first2=Walker |last3=Nilanjan |first3=Chakraborty |last4=Katia |first4=Sycara |last5=Michael |first5=Lewis |date=2016 |title=Human interaction with robot swarms: A survey |url=http://d-scholarship.pitt.edu/28437/1/hms.pdf |journal=IEEE Transactions on Human-Machine Systems |volume=46 |issue=1 |pages=9–26 |doi=10.1109/THMS.2015.2480801 |s2cid=9975315}}</ref>
