A Cost Too High to Protect the Sky? Lessons for Taiwan from the Wars in Ukraine and Iran | Global Taiwan Institute
AI Analysis
Taiwan is re-evaluating its defense strategy in light of drone warfare observed in Ukraine and Iran, recognizing the cost-effectiveness of loitering munitions and attritional tactics. The island is increasing its defense budget, focusing on both indigenous drone production and international partnerships, particularly with Ukraine, to build a resilient, multi-layered defense system. A shift towards lower-tier, disposable drone systems is being considered to counter China's numerical advantage.
Key Takeaways
- The cost disparity between interceptor missiles (e.g., Patriot) and loitering UAVs (e.g., Shahed-136) is driving a shift in warfare economics.
- Taiwan is adopting a 'Hellscape' doctrine, emphasizing a high concentration of expendable aerial and maritime drones for deterrence.
- Taiwan faces challenges in indigenous drone production due to the high cost of 'non-red' (non-Chinese) components, with Taiwanese drones costing 25% more than DJI equivalents.
- Taiwan is actively pursuing 'drone diplomacy' and partnerships, notably with Ukraine (Ukrainian IRON Cluster), Poland, and the US, to secure supply chains and expertise.
- Track II diplomacy is being utilized to circumvent formal diplomatic limitations and establish crucial supply links for drone technology and research.
Why It Matters
The success of low-cost drones in Ukraine and Iran demonstrates a vulnerability in traditional air defense systems and presents a viable asymmetric defense strategy for Taiwan against a larger adversary. Taiwan’s ability to rapidly develop and deploy a robust drone defense and offense capability is critical to deterring Chinese aggression and increasing the cost of any potential invasion. The partnerships being forged with Ukraine and other nations are crucial for accelerating this development.

Winning through Cost Attrition
Since September 2022, Russia has been actively launching Iranian-designed Shahed-136 loitering unmanned aerial vehicles (UAV). Moscow has since domesticated its production(naming its own Shahed drones “Geran-2”), intended to overwhelm Ukraine’s air-defense network and counter the supply of Patriot systems provided by the United States and other key ally states. However, a single Patriot missile costs around USD 3-4 million. Compared to the USD 20,000-50,000 production cost of a Shahed, this presents a clear 100:1 ratio in favor of Russia. [1] This prompted Ukraine to develop its own brand-new GPS-guided loitering UAV titled “The Sting”, costing only USD 2,000 per unit, balancing the unfavorable economic attrition tug-of-war.
In Iran, Washington was unable to adequately counter the launch of several ballistic missiles and Shahed drones targeting American bases or civilian infrastructures. The conflict has pressured the United Arab Emirates, Qatar, Kuwait, and Saudi Arabia to seek purchases of Ukraine’s low-cost interceptor drones rather than the US Patriot system. Moreover, on March 27, 2026, the American Prince Sultan Airbase based in Saudi Arabia was targeted by Iran, damaging a USD 270 million E-3 Sentry AWACS radar aircraft. Thus, Tehran was able to assert pressure on the US ability to monitor and detect future threats from Iran at a relatively low cost.
Both Ukraine and Iran have shown that cheap loitering UAVs have significantly shifted the dynamics of warfare. Taiwan has not been idle throughout the two major conflicts, closely observing the evolution of drone warfare, and reviewing its own existing defense strategy accordingly. Taiwan has planned production of indigenous unmanned surface vehicles (USV) – notably the Sea Shark(海鯊), the Kuai Chi(快奇), and the Endeavor Manta maritime drones – to address the asymmetric challenge it faces from the People’s Republic of China’s (PRC) much larger naval fleet. Drawing inspiration from Ukraine’s use of naval drones, Taipei seeks to counter the People’s Liberation Army Navy (PLAN)’s overwhelming advantage through a similar attritional strategy.
