On February 28, 2026, the United States and Israel launched a large-scale coordinated military strike against Iran, killing Supreme Leader Khamenei and much of Iran's senior leadership in the opening hours of the campaign. Yet despite crippling sanctions, a weakened economy, and the sudden decapitation of its political elite, Iran's military and Islamic Revolutionary Guard Corps responded swiftly with ballistic missiles and loitering munitions. The popular uprising that Washington and Tel Aviv had anticipated never materialized, and the hoped-for swift victory did not follow.
For Taiwan — geographically distant from the Middle East but acutely attentive to its lessons — the conflict carries implications beyond crude oil and natural gas supply disruptions. The ongoing U.S.-Israel-Iran war has provided a rare and sobering real-world stress test of the kind of integrated, multi-layered air and missile defense architecture that Taiwan is now constructing. On March 16, Taiwan's Ministry of National Defense presented a special report to the Legislative Yuan, drawing on lessons from the conflict and pledging to develop low-cost interceptors capable of countering large salvos of inexpensive rockets — a direct response to fears that the People's Liberation Army could exhaust Taiwan's expensive missile stockpiles through attrition.
What Is T-Dome? Taiwan's $10 Billion Missile Shield, Explained
Military sources note that the Ministry of National Defense's report stopped short of directly confronting the potential vulnerabilities of the Taiwan Dome (T-Dome) program. Its most useful contribution, analysts say, was finally providing the public with a clearer picture of a concept that had previously remained vague: a comprehensive, multi-layered, integrated air and missile defense system built by combining battlefield management systems, sensors, and launchers sourced from both domestic production and foreign procurement.
T-Dome is designed to achieve high situational awareness, layered interception, and effective engagement across the full spectrum of aerial threats — an ambition closely modeled on Israel's Integrated Air Defense System (IADS). Military officials acknowledge that when President Lai Ching-te unveiled the T-Dome concept in his National Day address on October 10, 2025, the architecture was explicitly inspired by Israel's approach: using the Arrow system for long-range ballistic missile threats, David's Sling for medium-range threats, and Iron Dome for short-range rockets and drones.
According to sources familiar with the planning, T-Dome as currently conceived may be even more complex than Israel's system. It envisions four distinct intercept layers — high, medium, low, and terminal — integrating a wider array of systems. The high-altitude layer would be handled by the domestically developed Tien Kung IV (Sky Bow IV, "Strong Bow") missile, currently moving toward mass production. The medium layer would be covered by U.S.-supplied Patriot PAC-3 and PAC-3 MSE missiles alongside the domestically produced Tien Kung III. The low-altitude layer would rely on ground-launched Tien Chien II (TC-2) air defense missiles and newly procured NASAMS systems. Terminal and very-low-altitude defense would fall to vehicle-mounted Avenger systems, twin-rail Stinger launchers, 35mm anti-aircraft guns, and Phalanx close-in weapon systems.
Israel's Air Defense Failed. Here's What That Means for Taiwan
Military analysts point to a critical structural difference between the Israeli model and Taiwan's situation: Israel's air defense layers were largely developed domestically or in close technical collaboration with the United States, minimizing integration challenges. Taiwan, by contrast, must invest enormous resources in the technically demanding task of linking domestically produced and U.S.-supplied systems under unified command and control.
The most critical element is the sensing and battle management layer. The Pave Paws long-range early warning radar (AN/FPS-132) at Leshan in Hsinchu would serve as T-Dome's highest-tier sensor, complemented by various missile defense radars, the planned Low-Tier Air and Missile Defense Sensor (LTAMDS), and the U.S.-made Integrated Battle Command System (IBCS). Together, these are intended to aggregate data from all land- and sea-based radars, airborne early warning aircraft, and long-range warning sensors across the Taiwan Strait theater, enabling coordinated engagement across all defense units.
Taiwan's military has estimated that full T-Dome construction will require at least approximately $10 billion USD. Internal skepticism exists on multiple fronts: some officers question whether relying on expensive interceptor missiles will simply invite the PLA to exhaust that shield cheaply through mass salvos of low-cost munitions. Others privately doubt whether T-Dome could handle hypersonic missile attacks at all. The U.S.-Israel-Iran war has revived those anxieties. That even the world's most advanced air defense systems have shown meaningful gaps when confronted with sustained Iranian missile and drone campaigns has deepened concerns — largely unspoken publicly — that T-Dome could prove more impressive on paper than in combat.
The $1.1B Radar Destroyed in Qatar — Taiwan Has the Same One
Iran, having rapidly lost air and naval superiority after the conflict began, has relied on sustained salvos of short- and medium-range ballistic missiles and loitering munitions, targeting both Israeli territory and U.S. military installations across Gulf states including Bahrain, Jordan, Qatar, and the United Arab Emirates. While operating under heavy Allied air dominance, Iran's strike effectiveness and precision have improved markedly compared with the June 2025 twelve-day Israel-Iran exchange.
Commercial satellite imagery reviewed as of March 15 showed that the AN/FPS-132 Pave Paws long-range early warning radar deployed at Al Udeid Air Base in Qatar — valued at approximately $1.1 billion USD — sustained significant damage. The AN/TPY-2 radars serving as the core sensors of THAAD batteries in Jordan, the UAE, and Qatar were also damaged to varying degrees, substantially degrading U.S. capacity to detect and intercept Iranian ballistic missiles. To compensate, the United States was compelled to emergency-redeploy THAAD assets from South Korea to the Middle East theater.
Israel's own multi-layer defense system has also shown strain after repeated saturation attacks. Intercept rates against Iranian hypersonic medium-range ballistic missiles have been notably disappointing regardless of whether the Arrow system, David's Sling, or Patriot PAC-3 was employed. Incidents in which eight or nine interceptors were fired against a single incoming missile without achieving a kill have been documented, raising concerns about both reliability and stockpile sustainability.
2,000 Interceptors vs. a PLA Drone Swarm
Military sources argue that since T-Dome is modeled on Israel's defense architecture, any vulnerabilities exposed in the Israeli system are likely to apply equally — or more severely — to Taiwan. The PLA's precision munitions and drone capabilities far exceed Iran's in both scale and sophistication.
The Republic of China military currently holds 384 PAC-3 missiles — its most capable ballistic missile defense asset — with over 100 PAC-3 MSE extended-range variants in delivery, 518 more planned for procurement, 462 NASAMS missiles on order, and domestically produced Tien Kung series missiles. Combined inventories are projected to exceed 2,000 rounds. Intelligence assessments suggest that at least 20 percent of Iran's missiles and suicide drones have successfully penetrated the U.S.-Israeli defense network — a penetration rate that carries grim implications for Taiwan's own shield.
Yet military sources caution that even this inventory may prove inadequate. Among the most tactically concerning threats are suicide drones converted from retired PLA J-6 fighter aircraft packed with explosives. If Taiwan's air defenses engage them, precious interceptor stockpiles are drawn down; if they do not, critical military infrastructure is destroyed. Either outcome serves the PLA's strategic interests. The PLA's air-launched standoff weapons — including the KD-88 and AFK-088C carried by bomber formations — add further pressure. The Gulf states' experience of expending hundreds of high-value interceptors within days illustrates how quickly even a robust stockpile can be depleted.
Taiwan Has Six Minutes. Israel Had Twenty
Beyond attrition economics, a deeper structural vulnerability concerns many defense planners: the Taiwan Strait's geography allows far less reaction time than the distances separating Israel from Iran. Israel's comparatively high intercept success rates owe much to the roughly 1,800-kilometer separation between the two countries, which provides approximately 20 minutes to detect, track, classify, and engage incoming threats. Across the Taiwan Strait — where operational distances rarely exceed 500 kilometers — Taiwan's defenders would have only six to seven minutes from detection to intercept.
This constraint helps explain why Iran was able to successfully strike the Pave Paws radar at Al Udeid and THAAD batteries in Qatar and the UAE: those targets were geographically much closer to Iranian launch sites, compressing American response timelines in ways structurally analogous to Taiwan's situation. The same physics that constrain Taiwan's reaction time also reduce the effectiveness of early warning sensors and increase the probability that incoming hypersonic or ballistic threats overwhelm a layered defense before it can fully engage.
Strike Back or Stand Pat: Taiwan's Unanswered Question
Taiwan's Ministry of National Defense has addressed PLA ballistic missile, cruise missile, and drone threats primarily through air defense system integration, AI-enhanced defense technologies, and the development of low-cost counter-rocket and counter-drone systems modeled on Iron Dome. Military sources acknowledge, however, that no combination of these approaches alters the fundamentally reactive posture that T-Dome entails.
A growing number of defense analysts and senior military officers advocate a rebalancing toward offensive deterrence, arguing that Taiwan should redirect a portion of T-Dome's budget toward dramatically expanding production of the domestically developed Qing Tian hypersonic cruise missile and the extended-range Hsiung Feng IIE cruise missile — systems capable of striking military targets on the mainland. The argument: an effective deterrent requires both a credible shield and a credible sword.
This debate touches on fundamental questions of defense strategy and the boundaries of U.S. support for Taiwan's force development — and is unlikely to be resolved quickly. What is clear is that the U.S.-Israel-Iran conflict has provided Taiwan's defense community with an unsettling empirical reference point: even the most capable, best-resourced integrated air defense systems in the world have meaningful limits, and those limits may be more pronounced in Taiwan's specific geographic and threat environment.
