Drone swarms are a game-changer in military operations, allowing for a high degree of autonomy and flexibility on the battlefield.
A single drone can be expensive and vulnerable to enemy fire, but a swarm of drones can overwhelm the enemy with sheer numbers and diversity of attack.
The concept of drone swarms has been around for a while, with the US military first experimenting with the idea in the early 2000s.
The US Navy has already demonstrated the effectiveness of drone swarms in combat, using them to attack enemy targets in 2017.

What is Drone Swarm
Drones are uncrewed aerial vehicles ranging in size from an inch to a wingspan of over 130 feet.
Drone swarms can be made up of at least three and up to thousands of drones.
These swarms can perform missions cooperatively with limited need for human attention and control.
Drone swarms can assist with tasks such as controlling a wildfire, assessing damages, finding access points, and suppressing the fire.
They can complete a variety of tasks in parallel without human supervision, making them more efficient and robust for certain applications.
Drone swarms can continue operating even if individual drones become inoperable.
They can use various methods of command and control, including preprogrammed missions and centralized control by a ground station or a single control drone.

Military Applications
Drone swarms have been tested in various military applications, including reconnaissance and surveillance.
These swarms can be used to gather intelligence on enemy positions, allowing military leaders to make more informed decisions.
In 2016, the US Navy conducted a successful drone swarm test, with 88 small drones flying in formation over the Chesapeake Bay.
Drone swarms can also be used for explosive ordnance disposal, with the ability to locate and clear explosive threats.
The US Army has explored the use of drone swarms for this purpose, with the goal of reducing the risk to soldiers.
Drone swarms can provide a high level of redundancy, with multiple drones able to complete a task even if one fails.
This makes them an attractive option for military applications where reliability is critical.
Control and Management
Control and Management is a crucial aspect of drone swarms. The Navy is working on a more sophisticated control system, which includes cooperative planning and allocation of tasks to swarm members.
Super Swarm already has cooperative planning and allocation of tasks built in, making it easier for the swarm to work together. This allows the swarm to act on its own initiative when it can't get decisions back from the operator.

The MATes project is specifically designed to make it easier for humans and swarms to work together. It gives the swarm more autonomy and feeds back information gathered by the swarm into its decision making.
The swarm can change its routing when drones detect new threats or send drones to investigate a newly identified target. This is a challenge for artificial intelligence, as thousands of autonomous drones mean thousands of points for error.
Modeling and simulation can help reduce the potential for error, but accounting for the complexities of the real world is tough.
Challenges and Limitations
Drone swarms can be a bit tricky to navigate, and there are some challenges that come with them.
Federal law prohibits operating drone swarms in restricted areas or for illegal activities like spying or deploying improvised explosive devices.
Operators must obtain a waiver to operate a drone swarm, as current regulations don't permit a person to control more than one drone at a time.
This is especially important for sensitive missions that could put humans in danger, where human intervention with control systems may be necessary.
To protect against the collection and storage of certain information, such as photographs or videos of individuals, protocols need to be in place.
Cybersecurity measures can help ensure drones aren't hijacked or hacked by bad actors and used for malicious purposes.
Some applications will require miniaturization of hardware, like sensors, as well as improved computing power.
Advancements in algorithms could better simulate swarm behavior and improve connectivity, communications, and decision-making among drones.
Fast Facts
Drones can range from a few to thousands in a swarm, using algorithms and local sensors to coordinate with minimal human intervention.
Advances in artificial intelligence and drone components have made swarms possible, even if they're limited to simpler missions like aerial light shows for now.
A swarm of drones could potentially be used to fight wildfires, detect crop disease, and more as the technology improves.
However, a hacker could redirect a drone swarm for malicious purposes, raising concerns over safety, privacy, and cybersecurity.

The First Wave
The US military is working on a project called Super Swarm, which aims to create massive swarms of drones that can travel long distances, carry out reconnaissance, and attack targets.
These swarms could potentially take out an entire battalion in one strike, as seen in Ukraine where small drones have already destroyed over a hundred Russian armored vehicles.
The swarms are seen as a solution to the US military's biggest headache: areas covered by advanced surface-to-air and anti-ship missiles that prevent US forces from entering.
Dozens or hundreds of drones might be shot down, but thousands more could get through, with enough munitions to take out air defense radar and other defenses.
Peter W. Singer, a Strategist at the think tank New America, believes that the problems of developing swarm coordination beyond simple movements are surmountable.
In many ways, it's no more daunting than the idea of flying a plane off a ship, or coordinating the movements of hundreds of manned planes, which must have seemed impossible in the past.
The swarm could take on various missions, from reconnaissance and intelligence gathering to electronic warfare and supply delivery, and work alongside crewed systems.
Just as Amazon envisions a world of both robotic trucks for bulk and small delivery drones for the final mile, we'll likely see the same with their military parallels.
However, experts like Kallenborn note that military researchers are already working on ways to counter swarms, which might include lasers, microwave weapons, or interceptor swarms.
