Global investment in drones and autonomous vehicles is transforming border security, combining advanced technology and strategy.
The use of autonomous systems for border security is growing rapidly worldwide. Autonomous drones, surface and underwater vehicles, as well as ground robots, are redefining border surveillance. Nations such as the USA, Turkey and Colombia are adopting these technologies to combat drug trafficking, illegal intrusions and protect critical infrastructures. The advancement of intelligent drones, capable of operating in swarms, and anti-drone systems (C-UAS) underlines a decisive technological race. This transformation is being driven by major investments in artificial intelligence, miniaturization and 5G networks.
Integrating drones into border surveillance
Surveillance drones have become a key tool for border authorities. In the USA, Customs and Border Protection (CBP) deploys small autonomous drones (sUAS) to collect data, monitor intrusions and reinforce field operations. For example, Operation Lone Star, initiated by Texas, uses these drones with night vision capabilities to locate cross-border activities and guide intervention teams.
Internationally, other countries are adopting similar approaches. In Thailand, drones are used to secure the border with Malaysia and combat drug traffickers. In Colombia, drones monitor the Venezuelan border to detect drug trafficking and suspicious activity. These systems reduce the risks for human forces, while increasing the effectiveness of interventions.
Drones such as the Bayraktar TB2, used by Turkey, cost around 5 million euros per unit and can operate for 24 hours without interruption, covering vast areas with unrivalled precision. These costs, though significant, are lower than those of traditional aerial surveillance systems.
The technological race in the drone sector
Rapid advances in drone technology are transforming their effectiveness and accessibility. Since 2020, conflicts such as that between Armenia and Azerbaijan have demonstrated the importance of drones in military operations. These systems have proven their ability not only to carry out surveillance missions, but also to strike precise targets. The emergence of kamikaze drones, such as the Iranian Shahed-136 or the Ukrainian Switchblade 600, underlines the trend towards multi-functional autonomous systems.
Modern drones incorporate technologies such as:
- Artificial intelligence (AI):
AI algorithms enable drones to make decisions in real time, such as avoiding obstacles or pursuing multiple targets. Autonomous swarms, made up of dozens of coordinated drones, are being developed to optimize missions. - Miniaturization and durability:
Recent drones are lighter and more durable, with extended flight capabilities. For example, the Switchblade 300 can be carried by a single person and deployed rapidly in the field. - Anti-drone countermeasures (C-UAS):
With the rise in drone use, anti-drone systems are becoming increasingly important. These technologies include jammers, directed projectiles and electromagnetic solutions to neutralize threats.
Investment: Global spending on drones is expected to reach 32 billion euros by 2028, up from 13 billion in 2022, according to MarketsandMarkets analysis.
Autonomous vehicles for maritime and land safety
In addition to drones, autonomous maritime and land vehicles are playing a growing role in border security. Maritime autonomous systems (USVs and UUVs) are used to protect coastlines and monitor underwater infrastructures such as cables and pipelines. For example, the Ukrainian Sea Baby and MAGURA V5 systems have demonstrated their effectiveness by damaging more than a third of the Russian fleet in the Black Sea.
On land, the American CBP is developing “automated dog” robots. These robots, equipped with cameras and sensors, can patrol rough terrain and detect threats without endangering human agents.
Practical applications:
- UUVs can inspect pipelines at depths of 3,000 meters.
- Ground robots can operate in extreme conditions, surveying desert or mountainous areas.
Costs: These technologies are still in the development phase, but the price of an advanced land robot can reach 250,000 euros, an investment justified by their efficiency and versatility.
Challenges and prospects for border security
Despite their advantages, autonomous systems present challenges. Their large-scale deployment requires appropriate infrastructures and clear legal frameworks. For example, the use of autonomous drones raises questions about data protection and liability in the event of error.
In addition, technologies for jamming or destroying drones pose a problem for operators. Authorities need to invest in solutions capable of neutralizing these threats without affecting allied systems.
Future opportunities:
Advances in AI and 5G communications could transform border security. Connected drones could transmit real-time data to command centers, reducing response times. What’s more, the integration of advanced sensors, such as thermal cameras, will increase their ability to detect illicit activity, even in difficult conditions.
Economic consequences: Countries that adopt these technologies will benefit from more secure borders, reducing the costs associated with illegal immigration and drug trafficking. On the other hand, those who do not invest risk being overtaken by growing technological threats.
