This groundbreaking initiative aims to counter the growing A2/AD capabilities of peer-state adversaries, particularly China and Russia, by deploying thousands of autonomous drones across aerial, surface, underwater, and ground domains.
By operating at a theater level, where drones can function independently and without constant human intervention, the U.S. military seeks to overturn the advantage that China has enjoyed with its extensive long-range missile capabilities. This research paper delves into the details of the AMASS program, its implications for U.S. national security, and its potential to reshape the military balance in an era of advanced warfare.
Introduction
In recent years, the United States has faced increasing challenges from anti-access and area-denial (A2/AD) systems employed by peer-state adversaries, particularly China. The growing range and sophistication of Chinese missiles, such as the DF-21D “carrier killer” anti-ship ballistic missile, have raised concerns about the ability of U.S. forces to operate freely in the Western Pacific.
The Threat of Chinese A2/AD Systems
China’s A2/AD capabilities pose a significant challenge to U.S. military operations in the Indo-Pacific region. With missiles like the DF-26 intermediate-range ballistic missile and the DF-17 hypersonic missile, China can target key U.S. assets and bases in the region. This has prompted the U.S. military to seek innovative solutions to counter these threats.
The Concept of Autonomous Multi-Domain Adaptive Swarms-of-Swarms (AMASS)
AMASS represents a paradigm shift in how the U.S. military plans to address A2/AD challenges. This program envisions the deployment of autonomous drones across various domains, including aerial, surface, underwater, and ground. These swarms of drones will be capable of working independently, reducing the need for constant communication and guidance from human operators.
Autonomy and Artificial Intelligence (AI)
The cornerstone of the AMASS program is autonomy. Human control in highly contested battlespaces is risky and technically challenging. To address this, DARPA emphasizes the use of artificial intelligence (AI)-enabled systems to achieve a high level of autonomy. These drones will communicate through AI liaisons using a common language, enabling them to coordinate the execution of theater-level effects.

Swarms of Swarms Protocol (SOSP)
One of the most ambitious aspects of AMASS is the concept of Swarms of Swarms, where one swarm of drones can control other swarms. This requires the development of the Swarms of Swarms Protocol (SOSP) language, enabling thousands of drones to act independently and in coordination with each other. This capability will have applications in attacking, surveilling, and electronically jamming enemy A2/AD installations.
The Swarms of Swarms Protocol (SOSP) is a language and communication protocol that enables swarms of autonomous systems to coordinate and cooperate with each other in a scalable and efficient manner. It is being developed by the US Defense Advanced Research Projects Agency (DARPA) as part of its Adaptive Multi-Agent Systems (AMASS) program.
Principles of SOSP
- Decentralized Communication: SOSP operates on a decentralized communication model, wherein each autonomous agent within a swarm communicates with other agents in its immediate vicinity. This information is then passed on to a higher-level control system responsible for swarm coordination.
- Interoperability: A defining feature of SOSP is its emphasis on interoperability. Autonomous systems from various manufacturers, operating on different platforms and using different communication protocols, can seamlessly integrate into the network. This ensures that a swarm of swarms can be composed of diverse agents with varying capabilities.
- Dynamic Network Formation: SOSP facilitates dynamic network formation, allowing swarms of different sizes and types to connect and collaborate as needed. This adaptability is particularly useful in scenarios where requirements and objectives may change over time.
- Scalability: SOSP is designed to scale efficiently, accommodating the coordination of swarms ranging from a few agents to massive fleets, depending on the requirements of the mission.
Applications of SOSP
- Search and Rescue Operations: SOSP is instrumental in enhancing the efficiency of search and rescue missions by enabling multiple drone swarms, equipped with different sensors and capabilities, to collaborate in real-time. This leads to quicker response times and improved situational awareness.
- Agriculture: In precision agriculture, SOSP can be used to coordinate fleets of autonomous tractors, drones, and robots to optimize planting, harvesting, and soil management. These interconnected swarms ensure efficient resource allocation and reduce waste.
- Military and Defense: SOSP holds great potential in military operations by allowing various autonomous assets, such as drones, ground vehicles, and submarines, to work together seamlessly, enhancing surveillance, reconnaissance, and tactical capabilities.
- Environmental Monitoring: Environmental agencies and researchers benefit from SOSP’s capabilities in deploying interconnected swarms to monitor ecosystems, wildlife, and climate patterns. This real-time data collection is invaluable for informed decision-making.
SOSP is designed to address the challenges of coordinating large numbers of autonomous systems in complex and dynamic environments. These challenges include:
- Communication overhead: As the number of autonomous systems in a swarm increases, the amount of communication required to coordinate them also increases. This can lead to performance bottlenecks and communication failures.
- Scalability: SOSP must be able to scale to support swarms of thousands or even millions of autonomous systems.
- Robustness: SOSP must be able to operate reliably even in the presence of noise, errors, and failures.
SOSP is based on a number of key concepts, including:
- Hierarchical organization: SOSP organizes swarms into a hierarchy of swarms, with each swarm having a leader that coordinates the actions of its members. This helps to reduce communication overhead and improve scalability.
- Asynchronous communication: SOSP uses asynchronous communication to allow swarms to coordinate even if some members of the swarm are temporarily out of communication range.
- Event-driven coordination: SOSP uses an event-driven coordination model to allow swarms to respond to changes in their environment in real time.
SOSP is still under development, but it has the potential to revolutionize the way that autonomous systems are coordinated and controlled. It could be used to develop new types of military systems, as well as commercial and civilian applications such as disaster response, search and rescue, and environmental monitoring.
Here are some specific examples of how SOSP could be used:
- Military: SOSP could be used to coordinate swarms of unmanned aerial vehicles (UAVs) to carry out missions such as surveillance, reconnaissance, and attack. It could also be used to coordinate swarms of ground robots to perform tasks such as mine clearance and search and rescue.
- Commercial: SOSP could be used to coordinate swarms of delivery drones to deliver packages to customers. It could also be used to coordinate swarms of agricultural robots to perform tasks such as harvesting crops and spraying pesticides.
- Civilian: SOSP could be used to coordinate swarms of disaster response robots to search for victims in the aftermath of a natural disaster. It could also be used to coordinate swarms of environmental monitoring robots to collect data on air and water quality.
Demonstrating the Viability of AMASS
