From Ukraine to Taiwan: Drone warfare lessons meet Indo-Pacific reality

As tensions simmer across the Taiwan Strait, Taiwan is quietly accelerating a shift toward drone-centric defense.

The nation is betting that swarms of low-cost, domestically produced systems can help offset the numerical and industrial advantages of China’s People’s Liberation Army Navy and its expanding network of maritime auxiliaries.

This approach reflects a broader recalibration in Taipei -- a move away from expensive, vulnerable platforms toward distributed, resilient and scalable capabilities designed to complicate any attempt at invasion or blockade.

At its core lies a simple calculation. In a high-intensity Indo-Pacific conflict, quantity, adaptability and survivability may matter more than traditional firepower.

From platforms to swarms

Taiwan’s embrace of drones is rooted in the concept of asymmetric warfare. Rather than matching China ship-for-ship or missile-for-missile, Taipei is investing in systems that can be mass-produced, dispersed and rapidly replaced.

“It’s not really about ‘swarms’ yet -- it’s about mass. Large volumes of drones used in salvos to overwhelm defenses and increase the probability of a successful strike,” said Molly Campbell, analyst at the Center for a New American Security in Washington, D.C.

Government plans call for the procurement of up to 200,000 drones over the coming decade, spanning aerial, maritime and hybrid platforms in what officials describe as a whole-of-society approach to resilience.

These include a broad mix of air (UAV), surface (USV) and underwater (UUV) drones, designed to operate in contested littoral environments.

The objective is clear: saturate defenses, disrupt amphibious operations and raise the cost of any Chinese military action.

“What Taiwan is trying to do is shift from heavy, high-end defense platforms to a more dispersed and resilient model,” Simona Alba Grano, a senior fellow at the Asia Society Policy Institute, told UPI.

In Taiwan’s case, where the goal is not to defeat China outright, but to make any invasion “extremely costly and uncertain,” such systems fit squarely within a broader denial strategy.

Lessons from Ukraine -- with limits

Taiwan’s drone push has been influenced by Ukraine’s battlefield innovations, where low-cost unmanned systems have reshaped modern warfare.

Ukraine’s use of maritime drones in the Black Sea, striking high-value naval targets with relatively inexpensive systems, provides a compelling reference point. It has also highlighted the importance of rapid iteration, short development cycles and close integration between operators and industry.

Taiwanese companies have begun engaging with this ecosystem, supplying components and spare parts to Ukrainian operators and seeking to gain exposure to combat-driven innovation.

Yet, the analogy has limits.

The Taiwan Strait presents a far more demanding operational environment as it is wider, more exposed and subject to extreme weather conditions. Systems must operate over longer distances, carry heavier payloads and withstand harsher maritime conditions.

At the same time, Ukraine’s drone ecosystem is shaped by continuous battlefield validation, giving its manufacturers a level of operational credibility that remains difficult to replicate elsewhere.

Advances in unmanned systems, including long-range platforms and “mothership” concepts, also are eroding the Taiwan Strait’s traditional role as a natural buffer, increasing the tempo of gray-zone interactions.

Ukraine has demonstrated what is possible. Taiwan must now determine what is adaptable to its own operational environment.

Industrial ambition meets resistance

Taiwan’s challenge is no longer strategic clarity, but execution on the ground. The gap between planning and implementation, particularly in scaling capabilities and coordinating across agencies, now defines the island’s defense posture.

“Ukraine’s drone production is on a completely different scale. It’s nowhere near comparable to what Taiwan is currently able to produce, “ Campbell said.

Authorities have signaled openness to integrating foreign expertise, pursuing joint production and accelerating domestic manufacturing. Yet, progress has been uneven.

Industry insiders point to reluctance among local manufacturers to share market opportunities within a rapidly expanding defense budget. This has constrained collaboration both domestically and internationally, slowing efforts to build a more integrated ecosystem.

This dynamic is particularly visible in Taiwan’s interactions with Ukraine. Despite Kyiv’s operational experience and willingness to cooperate, Taiwanese firms have at times resisted incorporating Ukrainian know-how into their platforms, limiting co-development opportunities.

At the same time, Taiwanese companies have sought to market their own systems abroad, often with limited success in operationally mature environments. The result is a mismatch between industrial ambition and battlefield credibility in a highly competitive, experience-driven sector.

The fragmentation of Taiwan’s drone ecosystem comes at a critical moment, when speed, scale and integration are essential.

Cutting the China supply chain

Another pillar of Taiwan’s strategy is reducing reliance on Chinese components, long a structural vulnerability in the global drone industry.

“Taiwan is making a concerted effort to eliminate Chinese components from its drone supply chain to reduce dependence and mitigate security risks, said Ava Shen, an analyst at the Eurasia Group.

Taipei is working with international partners, particularly the United States, to develop a secure, China-free supply chain for unmanned systems. This effort is now backed by policy initiatives in Washington, where bipartisan legislation seeks to expand joint drone production and strengthen industrial resilience between the two partners.

The objective is not only to secure supply chains, but also to align production ecosystems in ways that enhance interoperability and long-term sustainability.

However, decoupling comes with trade-offs. Eliminating Chinese components increases production costs, extends timelines and complicates scaling. These constraints risk slowing deployment at a moment when speed is critical.

Meanwhile, China continues to expand its own unmanned capabilities, including drone swarms, electronic warfare systems and the conversion of legacy platforms into remotely operated assets. The scale of its industrial base and the integration of civilian and military sectors present a formidable challenge.

If Taiwan’s approach emphasizes agility and innovation, China’s rests on mass, coordination and systemic depth.

Southeast Asia as regional test bed

Beyond Taiwan, Southeast Asia, particularly along the South China Sea littoral, is emerging as a practical testing ground for unmanned systems.

The United States has expanded drone support to regional partners, providing intelligence, surveillance and reconnaissance platforms such as the ScanEagle, RQ-20 Puma and Skydio X10 UAVs to countries including the Philippines, Vietnam, Malaysia and Indonesia. These systems are primarily used to enhance maritime awareness in contested areas.

The Philippines, under sustained pressure from Beijing, has become a focal point. The United States has deployed MQ-9A Reaper for extended surveillance missions and introduced maritime drones, such as the Devil Ray T-38.

Together, these deployments are turning parts of Southeast Asia into a real-world environment for testing unmanned concepts short of conflict, particularly in maritime surveillance and denial.

China has also deployed uncrewed surface vehicles such as the Sea Wing and Wave Glider types, many of which have been lost or recovered by fishermen and coast guards, in the South China Sea as well as in the Java Sea, highlighting both the spread and the fragility of these systems in contested waters.

Deterrence, escalation and uncertainty

Drones offer Taiwan a pathway to strengthen deterrence by denial, increasing the cost, complexity and uncertainty of any military action. But they also introduce new risks.

The proliferation of low-cost systems may lower the threshold for escalation, especially in ambiguous encounters involving coast guard or maritime militia vessels. What begins as signaling or harassment could escalate more rapidly in an environment saturated with autonomous or semi-autonomous platforms.

Moreover, drone networks depend heavily on communications, data links and supply chains - all of which are vulnerable to disruption through cyber operations or electronic warfare.

Race against time

For Taiwan, the shift toward drone-centric defense is both an opportunity and a race against time.

Drones offer a scalable and cost-effective means of offsetting China’s advantages. But success depends on overcoming internal fragmentation, accelerating production and adapting technologies to local operational realities.

The central question is no longer whether drones will shape the balance in the Taiwan Strait, but whether Taiwan can scale and integrate them fast enough to make deterrence credible.

As China continues to refine its own capabilities, the balance in the Strait may increasingly hinge on a simple but decisive factor: which side can deploy, adapt and sustain unmanned systems at scale.
