Unmanned surface vehicles (USVs), often referred to as maritime drones, are emerging as a transformative tool in the fight against maritime crimes across Africa, a continent where illegal fishing and other illicit activities pose persistent threats to security and economic stability.
These vessels, which can operate autonomously or under remote control, are gaining popularity due to their ability to detect suspicious activities without exposing personnel to danger. Equipped with advanced artificial intelligence autonomy systems, USVs gather, process, and transmit vital information, making them a cornerstone of modern maritime operations.
The appeal of USVs lies in their sophisticated technology. They feature enhanced communication systems that enable seamless data sharing with command centres, ensuring that operators remain well-informed through continuous surveillance and reconnaissance missions. According to Mike Ball, an editor at Defence Advancement, many of these vehicles are fitted with cutting-edge sensor suites, including cameras, sonar, radar, and acoustic systems.
As swarm intelligence and AI capabilities mature, these vessels will take on increasingly sophisticated roles, offering African nations new tools to safeguard their waters.
These tools provide a comprehensive view of the maritime environment, allowing for precise monitoring over vast areas. Some models even incorporate military-grade sensors and modular payloads, adding to their adaptability and effectiveness. A standout feature of certain USVs is their swarm capability, which allows multiple units to collaborate seamlessly. By using inter-vehicle communication, these platforms can perform coordinated tasks such as area surveillance or search-and-rescue missions. As Ball explains, this networked approach boosts operational efficiency and offers a scalable way to cover expansive maritime regions, a particularly valuable trait for African nations with long coastlines and limited resources. Whether fully autonomous or guided remotely, USVs adapt to mission needs through their advanced navigation systems, proving their versatility across a range of applications.
These applications are wide-ranging and practical. USVs are deployed for patrols, mine detection, anti-submarine warfare, and anti-piracy operations, offering a flexible response to diverse threats. Compared to traditional naval vessels, they are smaller, more fuel-efficient, and require fewer crew members, which translates to lower operational costs. This efficiency is a game-changer for African countries, where patrol capacity is often stretched thin due to budgetary and logistical constraints. In Africa, the potential of USVs to tackle illegal, unreported, and unregulated (IUU) fishing is especially compelling. These vessels can monitor areas where manned military ships cannot maintain a prolonged presence, observing, detecting, and deterring illicit activities. The data they collect could bolster global transparency efforts, share critical maritime information with regional allies, and pinpoint zones of intense fishing activity for authorities.
Beyond fisheries protection, USVs could assist in identifying fishing vessel movements and supporting search-and-rescue operations, enhancing safety and oversight in African waters. Denys Reva, a Maritime Security Researcher at the Institute for Security Studies (ISS), sees USVs as a revolutionary step forward for the continent. He argues that these cost-effective solutions are well-suited to Africa’s unique maritime challenges, providing a practical means to secure waters against evolving threats.
Reva’s optimism reflects a growing consensus that USVs could reshape maritime security in the region, offering both immediate benefits and long-term potential. Nigeria, one of Africa’s largest nations, has already embraced this technology. Last year, the Nigerian Navy acquired two SwiftSea Stalker USVs from Swiftship, a shipbuilder based in the United States. These vessels are destined for deployment in the Gulf of Guinea, the Niger Delta, and the Lake Chad Region—areas long troubled by insecurity and criminality, including rampant illegal fishing. For decades, Nigeria’s waters have suffered from the activities of foreign fleets, particularly Chinese industrial trawlers, costing the country an estimated £55 million annually.
The U.S. Navy is currently conducting tests on an innovative autonomous drone, known as TRITON, in the waters of West Africa during the Obangame Express multinational maritime exercise. The TRITON drone, capable of operating both above and below the water’s surface, is part of an initiative to support African nations in their efforts to combat piracy, the illicit drug trade, and other unlawful activities prevalent in the Gulf of Guinea.
Rear Adm. Michael Mattis, director of Strategic Effects at U.S. Naval Forces Europe-Africa, emphasised the significance of these trials, which aim to evaluate the drone’s suitability for extended, sustained operations in the region. This comes at a time when the U.S. is keen on strengthening ties with West African partners, particularly in light of recent political upheavals, such as the coup in Niger that led to the abandonment of a substantial U.S. drone base.
The arrival of USVs promises to strengthen the navy’s ability to monitor these waters more effectively, curbing economic losses and enhancing security. South Africa, too, is making its mark in this field. Legacy Marine, a local shipbuilder, is developing a 9.5-metre USV that relies on artificial intelligence and robotics for navigation. Believed to be the first fully built and tested USV in the country, this project signals South Africa’s ambition to harness homegrown technology for maritime defence. It’s a milestone that not only showcases innovation but also positions the nation as a contributor to the broader adoption of USVs across the continent.
The technology behind USVs is advancing at a brisk pace. Improvements in swarm intelligence, autonomous collaboration, and AI integration are enabling these platforms to take on more complex missions with greater independence. Mike Ball observes that USVs are increasingly integrated into naval and defence forces worldwide, a trend that suggests their role in Africa will only grow. This evolution could see USVs handling intricate tasks, from coordinated patrols to real-time threat detection, with minimal human intervention. Beyond their core military uses, USVs also enhance harbour and port security through regular patrols and inspections.
They can spot unauthorised vessels, monitor infrastructure, and respond quickly to potential dangers, ensuring safer coastal operations. In multi-domain operations, they serve as vital links within larger networked systems, working alongside manned ships, submarines, and aerial platforms. This interoperability allows for synchronised missions where data flows freely across assets, creating a unified operational picture that enhances decision-making. For African nations, the adoption of USVs reflects a pragmatic response to the dual challenges of limited resources and vast maritime domains. Their ability to operate in harsh conditions, combined with their affordability, makes them an appealing option for countries aiming to strengthen their naval presence without the heavy costs of traditional ships.
Nigeria’s acquisition and South Africa’s development efforts illustrate a broader shift towards innovative solutions, one that could improve operational effectiveness while supporting regional stability and economic growth. By curbing illegal fishing and other maritime crimes, USVs help protect vital resources and sustain the livelihoods of coastal communities. Looking ahead, USVs are likely to become a cornerstone of Africa’s maritime security framework.
As swarm intelligence and AI capabilities mature, these vessels will take on increasingly sophisticated roles, offering African nations new tools to safeguard their waters. The progress in Nigeria and South Africa is just the beginning, pointing to a future where autonomous systems play a central role in addressing the continent’s maritime needs. In essence, unmanned surface vehicles are carving out a vital place in Africa’s maritime operations. Their capacity to detect and deter illegal activities, paired with their cost-efficiency and technological prowess, positions them as a powerful asset in the battle against sea crimes. As countries like Nigeria and South Africa lead the charge in adopting and advancing this technology, Africa stands to gain improved security, greater transparency, and better management of its maritime resources. The shift towards autonomy in maritime operations is well underway, and USVs are steering the course.
