The business impact of low-cost UAVs

Executive summary

Low-cost drones have begun reshaping conflict and creating risks that extend far beyond the battlefield. Their affordability permits state and non-state actors to deploy them at scale, overwhelm more expensive air defense systems and target energy, transport and communications infrastructure, resulting in human and financial losses. Rapid innovation, including first-person-view and fiber-optic drone systems, is shortening the time available for air defense systems to adapt. For businesses, the threat is not limited to a successful strike: sightings, reconnaissance and airspace incursions can halt flights, suspend shipping, delay supply chains and raise security and insurance costs. Recent incidents across the Middle East, Ukraine and Europe display a widening imbalance between the low cost of generating disruption and the high cost of preventing it. Organizations should therefore treat drone activity as an operational resilience issue.

The proliferation of inexpensive unmanned aerial vehicles (UAVs) has profoundly transformed the modern security landscape, converting drones from niche military assets into one of the defining technologies of modern conflict. Initially used for intelligence, surveillance and reconnaissance, low-cost drones are now routinely employed to conduct long-range strikes, overwhelm sophisticated air defense systems and disrupt critical infrastructure at a fraction of the cost of conventional weaponry.^[1]

Recent increase in military drone usage during the Iran conflict and in Ukraine have demonstrated how commercially available and low-cost military drones can achieve disproportionate operational and strategic effects. Their widespread availability, combined with rapid technological innovation, has enabled both state and non-state actors to contest against far more expensive defensive capabilities, forcing governments to reconsider procurement priorities while accelerating investment in autonomous systems.^[2]

These implications extend well beyond the battlefield. Drone activity targeting energy infrastructure, commercial shipping, airports and other critical assets has highlighted the growing vulnerability of businesses operating within complex or unique security environments. Beyond kinetic attacks, sightings around strategic infrastructure can disrupt operations, delay transport, increase security costs and create significant uncertainty for organizations.

This report seeks to examine how low-cost drones are reshaping the modern threat landscape through three key themes: the increasing use of inexpensive drones in conventional conflict, the rapid evolution of drone technology, and the emergence of drone-related hybrid threats affecting critical infrastructure across Europe. These developments demonstrate why organizations should monitor drone activity as an increasingly persistent operational risk rather than a purely military concern.

Cheap drones, expensive defense

The widespread use of inexpensive unmanned aerial vehicles (UAVs) throughout the 2026 Iran conflict by the IRGC and it’s proxies, demonstrated how low-cost systems have become a central feature of modern warfare. Intelligence Fusion recorded 572 drone-related incidents across the Middle East between February and July 2026, illustrating the scale at which drones are now employed by both state and non-state actors. Rather than acting solely as supporting reconnaissance assets, drones were used alongside ballistic missiles to overwhelm air defense systems, target military infrastructure and place sustained pressure on defensive resources.

The IRGC has also increasingly combined one-way attack drones with ballistic missile salvos, employing large waves of inexpensive systems to overwhelm layered air-defense networks and exhaust expensive interceptor inventories. This approach underlines the economic advantage of low-cost drones, forcing defenders to expend significantly more expensive defensive munitions against comparatively inexpensive aerial threats.

The cost imbalance. A Shahed-series drone costs roughly US$35,000; a single Patriot PAC-3 interceptor costs roughly US$4 million, a cost ratio of around 114:1 in favor of the attacker.

This shift reflects a broader change in the economics of conflict. Cost-effectiveness has become a defining feature of modern drone warfare. According to CSIS, relatively inexpensive attack drones can force defenders to expend interceptors that cost many times more. Iran’s Shahed-series drones exemplify this approach. Costing approximately US$35,000 per unit, they are designed for mass production using a combination of domestically manufactured or reverse-engineered parts and commercially available components sourced through international supply chains, including Western-manufactured electronics and aerospace components procured through China and other intermediary markets. By comparison, a single Patriot PAC-3 interceptor costs approximately US$4 million, creating a cost ratio of around 114:1 in favor of the attacker. During sustained attacks, this imbalance places significant pressure on interceptor stockpiles, procurement budgets and long-term defensive readiness. Rather than relying on technological superiority, their effectiveness lies in overwhelming defensive systems through quantity and persistence while steadily increasing the financial and logistical burden on the defender.^[3][4]

Beyond their favorable cost exchange ratio, the growing accessibility of drone technology is accelerating its proliferation. Commercially available components, simplified manufacturing processes and widely available navigation and communications technologies have lowered the barriers to entry for both state and non-state actors. As a result, capabilities once largely confined to advanced militaries are becoming increasingly attainable, expanding the range of actors capable of threatening critical infrastructure and commercial assets.

During the conflict, Intelligence Fusion recorded multiple drone strikes targeting oil refineries, oil fields and oil terminals across the Gulf, highlighting the exposure of critical commercial infrastructure to relatively inexpensive aerial threats.

Energy infrastructure represents an attractive target because disruption can generate effects far beyond the immediate area of attack. As demonstrated by recent attacks across the Gulf, even limited strikes against refineries, storage facilities and export terminals can disrupt production, increase insurance premiums, affect regional energy markets and undermine confidence in critical infrastructure resilience. The scale of this exposure is significant: in August 2026, the International Energy Agency estimated that Gulf oil production remained 8.3 million barrels per day below pre-war levels.^[5][6]

The objective of these strikes is often not only physical destruction but also economic disruption. Even unsuccessful attacks can compel operators to suspend activity, increase security measures and absorb higher insurance and operating costs, amplifying the strategic effect of relatively inexpensive systems. Similarly, attacks affecting commercial shipping and maritime infrastructure can create wider economic consequences by increasing transit times, reducing shipping confidence and raising operating costs.^[7]

The Persian Gulf and Strait of Hormuz remain among the world’s most strategically important shipping corridors, through which around one-fifth of global oil consumption passes. While not every incident directly targets merchant vessels, maritime security incidents involving IRGC military forces have demonstrated how heightened regional tensions can disrupt commercial shipping. According to Lloyd’s List, attacks on vessels in the Middle East have become increasingly unpredictable, creating operational uncertainty for shipping companies through higher insurance premiums, rerouting, delays and elevated security costs. Intelligence Fusion recorded 67 maritime security incidents involving Iranian military forces across the Persian Gulf and Strait of Hormuz, illustrating the sustained pressure placed on one of the world’s most important commercial maritime corridors.^[8][9]

Intelligence Fusion also recorded a series of maritime and drone attacks along Saudi Arabia’s Red Sea coast during July and August 2026. For example, on 22 July, two Saudi-owned oil tankers were targeted southwest of Al Shuqaiq, followed five days later by a reported Houthi attack on a Saudi oil tanker near Jizan. On 24 August, a tanker was struck by an unidentified projectile approximately 63 nautical miles west of Yanbu. Although attribution varies between incidents, their concentration along a major commercial and energy shipping corridor demonstrates the continuing exposure of merchant vessels to hostile activity beyond the Persian Gulf.

For businesses operating in sectors such as energy, logistics, insurance and maritime transport, these developments demonstrate that the consequences of drone warfare increasingly extend beyond direct physical damage. Organizations may face higher operating costs through increased insurance premiums, supply chain disruption, enhanced security requirements and temporary operational restrictions, even where no successful strike occurs.

The operational flexibility of low-cost drones also increases the challenge for defenders. Unlike conventional missile systems, Shahed drones can be transported on civilian-style trucks, rapidly repositioned and launched from dispersed locations, reducing the effectiveness of pre-emptive strikes against production and launch sites. Their relatively simple design enables decentralized manufacturing and sustained production even under military pressure, reinforcing their value as an attritional capability capable of threatening energy infrastructure, commercial shipping and other strategic assets over prolonged periods.^[10]

The success of systems such as the Shahed demonstrates that the future effectiveness of unmanned systems is not necessarily driven by increasingly sophisticated technology, but by the ability to produce affordable platforms at scale. Rather than seeking to outperform advanced air defense systems technologically, attackers can instead overwhelm them through mass, persistence and favorable cost exchange ratios.

This shift is already influencing defense planning. Recognizing the lessons emerging from recent conflicts, governments are increasingly investing in inexpensive autonomous systems capable of delivering greater mass alongside conventional capabilities. The UK’s Defence Investment Plan, for example, concludes that “cheap, massed, precise systems now dominate” modern warfare, drawing directly on lessons from Ukraine. In response, the UK has committed more than £5 billion to autonomous systems by 2030, including its largest-ever investment in drones. Planned programs include funding for long-range one-way attack drones, next-generation surveillance UAVs under Project CORVUS, expanded counter-drone capabilities and the development of lower-cost cruise missiles informed by operational experience in Ukraine.^[11]

Innovation outpacing countermeasures

While the Iran–Israel conflict highlighted the economic advantages of low-cost drones, the war in Ukraine has demonstrated the pace at which unmanned systems continue to evolve. Rather than relying solely on increasingly sophisticated or expensive platforms, both sides have prioritized rapid innovation, adapting commercial technologies to overcome battlefield challenges and maintain operational advantage.

First-person view (FPV) drones have become one of the defining features of the conflict. Costing only a fraction of conventional precision-guided munitions, FPV drones have been used extensively to strike vehicles, defensive positions and logistics routes with a high degree of accuracy. Their widespread deployment has transformed the battlefield, enabling relatively inexpensive systems to deliver precision effects previously associated with significantly more expensive weapons.

One of the most notable developments has been the emergence of fiber-optic FPV drones. Unlike conventional radio-controlled systems, fiber-optic drones remain connected to their operator through a physical cable, making them largely immune to electronic jamming. As electronic warfare became increasingly effective at disrupting radio-controlled drones, operators adapted by deploying fiber-optic variants, illustrating the speed at which drone technology continues to evolve in response to countermeasures. Their resistance to electronic warfare has, in turn, encouraged greater reliance on comparatively simple physical and kinetic defenses, including netting and shotguns, demonstrating how increasingly sophisticated threats do not necessarily require equally sophisticated countermeasures.

The operational impact of these systems has extended beyond individual strikes. Drone activity has played a significant role in disrupting military logistics, where persistent UAV surveillance and strike capabilities have complicated the movement of personnel, equipment and supplies. Rather than seeking decisive battlefield victories, drone operators have increasingly focused on degrading freedom of movement, forcing adversaries to alter logistics routes, delay resupply operations and commit additional resources to force protection.

The proliferation of FPV drone technology has not remained confined to Ukraine. Intelligence Fusion reporting indicates Hezbollah has increasingly employed FPV drones against Israeli military targets in southern Lebanon, illustrating how battlefield innovations are rapidly adopted by other state and non-state actors. As these innovations spread, organizations responsible for protecting critical infrastructure cannot assume that existing counter-drone measures will remain effective. Instead, the continued evolution of inexpensive unmanned systems is likely to challenge both military and civilian security planning, reinforcing the need for continuous monitoring of emerging technologies and tactics.

The rapid pace of adaptation also presents a challenge for organizations investing in counter-drone capabilities. Technologies designed to mitigate today’s threats may become obsolete within relatively short timeframes as operators continue to adopt new guidance systems, communications methods and operational tactics. Businesses responsible for protecting critical infrastructure should therefore view drone security as an evolving capability rather than a one-time investment.

From battlefields to business risk

The increasing use of drones in modern conflicts has highlighted a broader challenge for governments and businesses alike: the proliferation of inexpensive unmanned systems beyond active warzones. While Europe has not experienced drone activity on the same scale as conflicts in the Middle East or Ukraine, repeated sightings around critical infrastructure demonstrate that organizations are increasingly operating within a more contested security environment.

Between March 2025 and July 2026, Intelligence Fusion recorded multiple drone sightings affecting energy and maritime infrastructure across Northern and Central Europe. These incidents involved offshore energy assets, ports and other strategically significant locations, illustrating how inexpensive drones can create operational uncertainty without conducting a kinetic attack.

Unlike conventional military operations, many of these incidents form part of a broader pattern of hybrid activity. The August 2026 incident at Leipzig/Halle Airport illustrates the potential escalation of this threat: an explosive-laden drone was discovered near Ukrainian cargo aircraft, while a separate cargo aircraft sustained damage after colliding with a suspected drone before diverting safely to Hanover. German authorities subsequently described the events as a “hybrid attack scenario” and a new level of threat. Beyond immediate operational disruption, repeated drone activity may also serve broader intelligence-gathering, sabotage and hybrid warfare objectives.

Unattributed drone flights around ports, offshore energy assets, airports and other critical infrastructure can also enable hostile actors to gather intelligence, map security arrangements and identify vulnerabilities without conducting a physical attack. Recurrent sightings may also test the speed and effectiveness of security responses, emergency procedures and law enforcement coordination, providing valuable information for future operations. Even where no hostile intent is ultimately confirmed, such incidents can generate uncertainty, divert security resources and erode public confidence in the resilience of critical infrastructure. For businesses, the challenge is therefore not limited to preventing drone attacks, but also recognizing that persistent drone activity may form part of a wider campaign to collect intelligence, probe defenses and create sustained operational and psychological pressure on organizations and their personnel.

The operators are frequently unidentified, attribution remains difficult, and the intent may extend beyond causing physical damage. Persistent drone activity around critical infrastructure can delay operations, prompt security investigations, increase surveillance costs and force temporary restrictions while authorities assess the threat. In sectors such as energy and maritime logistics, even short periods of disruption can have disproportionate operational and financial consequences.

The aviation sector provides a clear example of this challenge. Repeated drone sightings near airports have demonstrated how a relatively inexpensive platform can disrupt commercial operations without ever engaging a target. Temporary airspace restrictions, flight delays and emergency response measures can affect thousands of passengers, interrupt freight movements and generate significant financial losses for operators. As the availability of commercial drone technology continues to grow, organizations responsible for transport infrastructure should expect drone-related disruptions to become an increasingly persistent operational consideration.

Unlike traditional terrorist attacks, drone-related airport disruption does not require a successful strike to achieve operational impact. Temporary airspace restrictions can rapidly cascade through airline schedules, affecting freight operations, passenger movements and airport staffing. For operators managing critical transport infrastructure, distinguishing between nuisance activity, criminal behavior and hostile reconnaissance has become an increasingly important security challenge.

The United Kingdom and other European governments have already begun adapting to this evolving threat. Recent defense initiatives have placed greater emphasis on expanding domestic drone production, integrating autonomous systems into military planning and improving counter-unmanned aerial system (C-UAS) capabilities. In the UK, this includes Project NYX, which aims to field up to 24 autonomous armed drones alongside Apache helicopters by 2030; Project Corvus, which will procure up to 24 surveillance drones to replace Watchkeeper; new uncrewed ground vehicles; and development of autonomous aircraft to operate alongside crewed RAF platforms. The government has also established an Uncrewed Systems Taskforce and is investing in a major drone testing facility at Swindon. In Europe plans include the development of AI- and 5G-enabled drone detection, joint procurement and deployment of counter-drone systems around critical infrastructure, a €250 million program for counter-drone and surveillance capabilities at land and maritime borders, a counter-drone center of excellence, and potential rapid-response counter-drone teams.^[12][13]

While these investments acknowledge the growing importance of drones in future conflicts, they also highlight a wider reality: inexpensive unmanned systems are no longer solely a military concern. Businesses operating around critical infrastructure, transport networks and strategic assets must increasingly consider drone activity as part of their wider security and resilience planning.

Conclusion

The rapid proliferation of low-cost drones has fundamentally altered the security landscape, challenging long-held assumptions about the relationship between capability, cost and operational impact. Recent conflicts in the Middle East have demonstrated how inexpensive UAVs can overwhelm sophisticated air defense systems and threaten strategically important infrastructure, while developments in Ukraine have highlighted the speed at which drone technology continues to evolve in response to battlefield countermeasures.

As these technologies proliferate beyond active conflict zones, the implications increasingly extend to the commercial sector. Drone sightings around airports, energy infrastructure, ports and other critical assets across Europe illustrate that organizations do not need to be located within a warzone to experience disruption. In many cases, the operational effects, flight delays, temporary shutdowns, heightened security responses and increased uncertainty, can be achieved without a single successful strike.

This shift is already influencing how critical infrastructure is protected. Satellite imagery reportedly shows large protective metal structures constructed around fuel storage tanks at Dubai International Airport after one tank was previously struck by an IRGC drone. The response illustrates how the drone threat can generate costs beyond the immediate damage caused by an attack, forcing operators to invest in physical hardening and additional layers of protection.^[14]

Governments are already responding by increasing investment in autonomous systems, expanding domestic drone production and strengthening counter-unmanned aerial system capabilities. The UK’s Defence Investment Plan reflects this shift, committing more than £5 billion to autonomous systems by 2030 and explicitly recognizing that the lessons of Ukraine require a greater emphasis on low-cost, massed and autonomous capabilities. Such investments demonstrate that drones are no longer viewed as niche capabilities, but as central components of future military operations.^[15]

For organizations operating within critical infrastructure sectors, the growing prevalence of drones reinforces the importance of proactive security planning, timely intelligence and continuous monitoring of emerging threats. While the methods employed by state and non-state actors will continue to develop, the underlying trend is unlikely to change. Low-cost unmanned systems are becoming an enduring feature of the global security environment. As recent conflicts have demonstrated, their strategic value lies not only in their military effectiveness but also in their ability to impose disproportionate economic costs on both military and civilian defenders. This dynamic is likely to remain a defining characteristic of future conflicts and an increasingly important consideration for organizations responsible for protecting critical infrastructure.

Their affordability, scalability and ease of production ensure they will remain accessible to a growing range of state and non-state actors, reinforcing the need for organizations to incorporate drone-related risks into long-term security and resilience planning. Understanding how these technologies are employed—and recognizing their potential to disrupt operations beyond the battlefield—will be essential for businesses seeking to build resilience in an increasingly contested operating environment.

The future challenge for organizations is therefore unlikely to be the occasional appearance of drone technology, but its normalization. As costs continue to fall and capabilities improve, low-cost drones are expected to become an enduring feature of the global operating environment. Businesses that integrate drone-related threats into security planning, intelligence monitoring and resilience strategies will be better positioned to manage an increasingly contested risk landscape.

Key takeaways

• Low-cost drones are becoming increasingly accessible to both state and non-state actors.
• Critical infrastructure, including energy, maritime and transport sectors, is increasingly exposed to drone-related disruption.
• Drone incidents may create significant operational impacts even without causing physical damage.
• Rapid technological adaptation means counter-drone measures require continual review.
• Organizations should incorporate drone threats into security, resilience and business continuity planning.
