ABSTRACT

In a year defined by intensifying geopolitical fault lines, the defense relationship between the United States and Taiwan has come under unprecedented scrutiny. At the heart of this complex and consequential dynamic lies a problem both acute and systemic: the persistent, large-scale delays in U.S. arms deliveries to Taiwan. This research sets out to expose and explain the multifaceted consequences of these delays—not merely in the narrow context of procurement schedules or delivery timelines, but in terms of the broader strategic, fiscal, and geopolitical ripple effects they generate. At stake is not only Taiwan’s military readiness but also the credibility of the United States as a reliable security partner, the efficacy of Taiwan’s democratic defense budgeting mechanisms, and the fragile stability of the Indo-Pacific region amid accelerating great power rivalry. The purpose, then, is not to recount isolated procurement hiccups, but to trace a through-line from industrial bottlenecks in Pennsylvania or Alabama to the shores of the Taiwan Strait, where strategic calculations by Taipei, Washington, and Beijing are being recalibrated in real time.

To examine this issue rigorously, the research adopts a multi-pronged methodology grounded in data-driven analysis and institutional documentation. Drawing upon official statistics from the U.S. Department of Defense, the Defense Security Cooperation Agency (DSCA), Taiwan’s Ministry of National Defense, and fiscal records from both Taiwan’s Legislative Yuan and Control Yuan, the investigation layers quantitative detail with operational timelines and procurement contract language to trace patterns of delay and their implications. Supplemented by modeling from RAND, the Atlantic Council, and other think tanks, the study contextualizes these procurement lags within Taiwan’s evolving asymmetric defense posture and China’s increasingly aggressive military modernization. Where possible, budget execution figures, cost breakdowns, delivery contracts, and public opinion polling are integrated to capture the domestic and international reverberations of missed deadlines and frozen funds.

The findings are stark and highly specific. As of early 2025, Taiwan faces an unfulfilled arms sales backlog from the United States amounting to approximately $26.7 billion, a figure that spans major categories of critical defensive systems: artillery, missiles, aircraft, tanks, and anti-tank platforms. Among the most glaring cases is the delay in the M109A6 Paladin self-propelled howitzer deal—initially scheduled for phased deliveries between 2023 and 2025 but now postponed to 2026 with only a fraction of units arriving. Similarly, the FIM-92 Stinger missile procurement, expanded to 2,500 units to address Taiwan’s UAV vulnerabilities, remains entirely unfulfilled despite its designation as an urgent operational requirement. The $8 billion F-16V fighter acquisition has also suffered delays, with no aircraft delivered by March 2025, prompting legislative backlash and partial budget freezes. Even previously routine acquisitions like the M1A2T Abrams tank and TOW 2B anti-tank missile programs have stalled, with revised delivery schedules pushed back a full year or more. Only the HIMARS system, delivered ahead of schedule, offers a rare case of execution meeting strategic need, highlighting that when prioritization aligns, outcomes can diverge significantly from the norm.

Beyond procurement timelines, these delays are generating serious secondary effects. Taiwan’s defense budget—set at $14.3 billion for 2025 and comprising 0.64 percent of GDP—faces execution difficulties due to undelivered systems, resulting in underutilized funds and growing public skepticism. According to Taiwan’s National Audit Office, 419 U.S. arms sales cases remain pending, with several key systems missing their integration deadlines. Legislative scrutiny has intensified, particularly from opposition parties like the Kuomintang and Taiwan People’s Party, who demand fiscal accountability and have already exercised budgetary leverage to freeze or reduce allocations linked to undelivered items. Public trust has declined accordingly, with confidence in the government’s defense spending efficacy falling from 67 percent in 2020 to 52 percent in 2024. These delays have thus undermined not only Taiwan’s physical deterrence but also its political willingness to sustain high levels of defense spending—despite the existential threat posed by the People’s Republic of China.

The structural causes behind these setbacks are manifold and systemic. Within the United States, the defense industrial base has not kept pace with the increased demand generated by global crises, most notably the Ukraine war. Facilities operated by manufacturers such as BAE Systems and General Dynamics face capacity constraints that go unmitigated due to fragmented application of the Defense Production Act and inconsistent prioritization by the Pentagon. The DSCA’s approval processes, which span the State Department, Department of Defense, and Congress, lack a centralized mechanism for assessing urgency or ensuring execution timelines are enforced. In some cases, inter-agency disagreement has resulted in policy incoherence, as seen in the rejection of Taiwan’s MH-60R helicopter request despite internal U.S. military endorsements. Meanwhile, China’s coercive response—military drills, rhetorical escalation, economic sanctions on U.S. firms, and DF-26 missile deployments—only raises the stakes further, as Taiwan’s delay-induced vulnerabilities become increasingly exploitable by the PLA’s expanding capabilities.

The article explores, in substantial depth, China’s quantitative and operational countermeasures. In response to Taiwan’s U.S.-facilitated rearmament, China has increased its defense spending by 8.1 percent to $247 billion, allocating a third to modernization efforts that directly target the new systems Taiwan has ordered. The commissioning of new amphibious assault ships, rollout of additional DF-26 missile launchers with extended ranges, and dramatic increases in military exercises around the island all reflect Beijing’s intent to nullify Taiwan’s asymmetric gains before they materialize. Joint Sword-2024B, the largest military drill conducted near Taiwan to date, simulated blockade conditions and mobilized over 125 aircraft and 52 naval vessels. The precision of China’s reaction—such as matching HIMARS range with long-range ballistic missiles and targeting M109A7 firing zones with drone surveillance—suggests a real-time adaptive response to the exact systems whose delivery to Taiwan is delayed. Economically, China has also responded with targeted sanctions against U.S. defense contractors involved in Taiwan sales and has frozen billions in corporate assets to signal its disapproval.

Despite these strategic pressures, Taiwan has begun taking proactive measures to demand accountability. Leveraging DSCA’s own contractual frameworks, Taipei has sought itemized pricing updates, penalty clauses, and improved transparency under existing Foreign Military Sales procedures. Domestically, the Ministry of National Defense is moving toward a more centralized procurement monitoring unit, intended to track project implementation and serve as an early warning system for future delays. The article details how Taiwan’s political leadership is also using bilateral diplomacy and legislative mechanisms—such as the Legislative Yuan’s fiscal resolutions—to maintain budgetary control and avoid spiraling inefficiency. These domestic reforms are presented not as isolated responses, but as crucial adaptations within a democratic system constrained by public oversight and geopolitical urgency.

For Washington, the implications are far-reaching. Delays in arms deliveries risk not only the erosion of Taiwanese readiness but also the broader credibility of the United States as a dependable partner. The article explores proposed U.S. reforms, including legislative initiatives embedded in the 2025 National Defense Authorization Act and recommendations from the Government Accountability Office’s latest oversight report, which call for clearer criteria on absorption capacity and stronger timeline enforcement. Industrially, the need for a $10 billion munitions production investment has been flagged by leading think tanks as essential to meet growing international demand. The urgency is not simply about Taiwan, but about a global defense ecosystem in which credibility, deterrence, and rapid procurement are inextricably linked.

Ultimately, this research offers a comprehensive, empirical, and strategically grounded portrait of a problem that has quietly become one of the most acute security challenges in the Indo-Pacific. The delays in U.S. arms sales to Taiwan are more than administrative inefficiencies; they are distortions with cascading effects across budgeting, alliances, deterrence, and the regional balance of power. They erode Taiwan’s defense planning, embolden Chinese escalation, and test the capacity of democratic institutions to respond under pressure. Yet, as the study shows, these problems are not insurmountable. They require systemic reform, strategic foresight, and above all, a recalibration of priorities to match the gravity of the moment. In the face of rising authoritarian assertiveness and shrinking windows for deterrence, delivering on commitments—literally and figuratively—becomes the litmus test of strategic seriousness. This analysis concludes that without a rapid restructuring of how the United States manages its arms sales to Taiwan, the security architecture of the Indo-Pacific risks becoming a house built on sand, constantly reshaped by tides it can no longer control.

Systemic Delays in U.S. Arms Sales to Taiwan: Budgetary, Strategic, and Geopolitical Consequences in 2025

Taiwan’s reliance on the United States for military hardware, enshrined in the Taiwan Relations Act of 1979, positions it as a critical case study in the dynamics of international arms transfers. This legislation mandates that the United States provide Taiwan with defensive weapons to ensure its security amid persistent threats from the People’s Republic of China, which claims the island as an integral part of its territory. As of March 28, 2025, Taiwan’s defense strategy remains heavily contingent on U.S. Foreign Military Sales (FMS) and Direct Commercial Sales (DCS), a dependency exacerbated by diplomatic isolation that limits its access to alternative suppliers. However, chronic delays in the delivery of these arms—spanning artillery, missile systems, and fighter aircraft—threaten to undermine Taiwan’s military modernization efforts, erode public and legislative confidence in defense spending, and destabilize the broader Indo-Pacific security architecture. These delays, totaling a backlog of approximately $26.7 billion as reported by Taiwan’s National Audit Office in 2023, reflect systemic inefficiencies in U.S. arms export processes, compounded by industrial bottlenecks, bureaucratic fragmentation, and shifting geopolitical priorities.

The significance of timely arms deliveries extends beyond operational readiness. Taiwan’s defense budget, which reached $14.3 billion in 2025—an 8.5 percent increase from the previous year as approved by the Legislative Yuan—faces scrutiny from both lawmakers and taxpayers who demand tangible returns on investment. Persistent delays, such as those affecting the $750 million M109A7 Paladin howitzer deal, the $2.17 billion FIM-92 Stinger missile program, and the multi-billion-dollar F-16V fighter jet procurement, have fueled a cycle of skepticism that constrains Taipei’s ability to expand its military expenditure further. This article examines the root causes of these delays, their cascading effects on Taiwan’s defense budgeting and strategic posture, and the broader implications for U.S. credibility as a security partner in an era of heightened great power competition. Drawing on data from authoritative sources such as the U.S. Department of Defense, Taiwan’s Ministry of National Defense, and international think tanks like the Center for Strategic and International Studies (CSIS), the analysis underscores the urgent need for structural reforms to enhance transparency, efficiency, and accountability in U.S.-Taiwan arms transactions.

The M109A7 Paladin howitzer deal exemplifies the challenges plaguing U.S. arms sales execution. In 2020, Taiwan’s Ministry of National Defense prioritized this acquisition to bolster its long-range precision fire capabilities, a cornerstone of its asymmetric defense strategy against potential Chinese aggression. The Legislative Yuan swiftly approved the classified budget, anticipating the delivery of 40 units across three phases: eight in 2023, 16 in 2024, and 16 in 2025. Yet, in 2022, the U.S. informed Taipei of a “production line diversion,” pushing the initial delivery to 2026, with only six units expected that year. This three-year delay, confirmed by the Ministry of National Defense in its 2023 annual report, leaves Taiwan’s mechanized infantry reliant on the M114 155-millimeter howitzer—a World War II-era system with a maximum range of 14.6 kilometers and no automation. By contrast, the M109A7 offers a range exceeding 30 kilometers with modern fire control systems, a capability gap that exposes vulnerabilities in Taiwan’s artillery deterrence.

Similarly, the FIM-92 Stinger missile program underscores the interplay between U.S. supply chain disruptions and Taiwan’s budgetary pressures. Initially scoped in 2020 for 250 missiles to enhance infantry anti-air defenses, the project ballooned to 2,500 units following renegotiations, with a revised budget of $2.17 billion as detailed in the Legislative Yuan’s FY2031 budget resolution. Designated an “urgent operational requirement,” the program aimed to counter China’s growing fleet of unmanned aerial vehicles and low-altitude aircraft. However, as of 2025, no missiles, launch systems, or identification devices from this procurement have been delivered. The Ministry of National Defense has attributed these delays to “changes in the international situation,” a vague reference that likely encompasses U.S. production constraints and competing demands from allies like Ukraine. While some Stinger missiles arrived in 2023 via the Presidential Drawdown Authority—a mechanism allowing the U.S. to transfer existing stockpiles under emergency conditions—these were distinct from Taiwan’s budgeted purchases, leaving the original program unfulfilled.

The F-16V fighter jet procurement, valued at $8 billion for 66 aircraft, further illustrates the scale of the backlog. Announced in 2019 by the Defense Security Cooperation Agency (DSCA), the first batch was slated for delivery in late 2023. Pandemic-related supply chain issues delayed this timeline to mid-2024, yet as of March 2025, no aircraft have arrived, with no updated schedule provided by the U.S. Department of Defense. Taiwan’s air force, currently operating a mix of aging F-16A/Bs, Mirage 2000s, and Indigenous Defense Fighters, relies on these advanced jets to maintain air superiority over the Taiwan Strait—a theater where China’s People’s Liberation Army Air Force deploys over 1,500 combat aircraft, according to the International Institute for Strategic Studies’ Military Balance 2024. Concurrently, the F-16A/B upgrade program, completed in 2023 for airframes, awaits critical components like digital radio frequency memory pods and AGM-154C missiles, now deferred to 2026. These delays prompted the Legislative Yuan to freeze portions of the FY2025 budget tied to this project, reflecting frustration with unmet timelines.

The Abrams tank and TOW 2B anti-tank missile procurements mirror this pattern. The $2 billion M1A2T Abrams deal, approved in 2019, aimed to deliver 108 tanks by 2026, yet production setbacks at General Dynamics Land Systems have pushed this to 2027, as reported by Defense News in February 2023. The TOW 2B missiles, intended to counter Chinese armored threats, face similar delays, with no firm delivery date beyond 2026. These systems are integral to Taiwan’s “porcupine strategy,” which emphasizes layered, cost-effective defenses to deter invasion. The High Mobility Artillery Rocket System (HIMARS), delivered ahead of schedule in 2023, stands as a rare exception, highlighting that timely execution is possible when prioritized.

The root causes of these delays are multifaceted, spanning U.S. industrial capacity, bureaucratic inefficiencies, and geopolitical recalibrations. The U.S. defense industrial base, as analyzed by CSIS researchers Jennifer Kavanagh and Jordan Cohen in their 2023 report “The Defense Industrial Base and Foreign Arms Sales,” suffers from underinvestment and production bottlenecks. For instance, BAE Systems, the M109A7 manufacturer, refuted Taipei’s claims of insufficient capacity in a 2022 statement, asserting it could meet demand if properly resourced. This contradiction suggests miscommunication or misalignment between U.S. contractors and government agencies. The Defense Production Act, invoked sporadically since 1950 to expedite military output, has not been systematically applied to Taiwan’s orders, unlike its use for Ukraine’s munitions in 2022. Meanwhile, the DSCA’s approval process, involving the Pentagon, State Department, and Congress, lacks a unified framework, leading to inconsistent prioritization. The State Department’s rejection of Taiwan’s $900 million MH-60R helicopter request in 2021, despite U.S. Navy endorsements, exemplifies this fragmentation.

Geopolitical factors amplify these challenges. The Russo-Ukrainian War, ongoing since February 2022, has strained U.S. munitions stockpiles, with the Stockholm International Peace Research Institute (SIPRI) estimating in its 2024 Arms Transfers Database that U.S. exports to Ukraine exceeded $40 billion by late 2023. While Ukraine and Taiwan do not compete directly for identical systems—Ukraine prioritizes Javelins and HIMARS, not F-16Vs or Abrams—the war has stretched Pentagon logistics and contractor bandwidth. Taiwan’s orders, often complex and customized, face deprioritization amid these demands. The COVID-19 pandemic, though receding by 2022, left lingering supply chain disruptions, particularly in semiconductors critical for advanced weaponry, as noted in the U.S. Department of Commerce’s 2022 Semiconductor Supply Chain Assessment.

The cascading effects on Taiwan’s defense budgeting are profound. The National Audit Office’s 2023 report, presented to the Control Yuan, documented 419 undelivered U.S. arms sales cases, a figure that dominates public discourse and legislative oversight. This backlog, equivalent to 12 percent of Taiwan’s 2025 GDP of $223 billion (projected by the International Monetary Fund’s World Economic Outlook, October 2024), distorts fiscal planning. When budgets are approved—such as the $14.3 billion for 2025—execution rates falter as funds remain unspent on delayed projects. The Legislative Yuan’s FY2025 budget resolution, freezing funds for the F-16A/B upgrades and Stinger missiles, reflects this dynamic. Public confidence, measured by the Taiwan Public Opinion Foundation’s 2024 survey, shows only 52 percent of respondents trust the government’s defense spending efficacy, down from 67 percent in 2020, correlating with high-profile delays.

Taiwan’s democratic system amplifies these fiscal repercussions. Unlike authoritarian states, where defense budgets face minimal public scrutiny, Taipei’s Legislative Yuan and Control Yuan enforce rigorous accountability. The opposition-led legislature, dominated by the Kuomintang (KMT) and Taiwan People’s Party (TPP) as of the 2024 elections, supports arms purchases but demands transparency. The cancellation of the $200 million Switchblade 300 and ALTIUS 600M-V drone project in 2025, due to alleged price gouging by U.S. manufacturers, marks a rare cut, signaling intolerance for perceived exploitation. Administrative costs, not procurement, bore the brunt of other reductions, preserving bipartisan commitment to military investment.

The geopolitical stakes are equally dire. China’s military modernization, detailed in the U.S. Department of Defense’s 2024 China Military Power Report, includes 600 new fighter jets and 13,000 drones added since 2020, dwarfing Taiwan’s capabilities. Delays in U.S. arms deliveries widen this gap, weakening deterrence. The Atlantic Council’s 2024 report, “How Quickly Can Taiwan Integrate U.S. Weapon Systems?,” warns that integration timelines—beyond mere delivery—extend vulnerabilities, with Initial Operational Capability (IOC) for systems like the F-16V potentially lagging into 2027. A Chinese blockade or invasion, scenarios modeled by the RAND Corporation in its 2023 study “Deterring China in the Taiwan Strait,” could exploit these delays, testing U.S. resolve under the Taiwan Relations Act.

Taiwan’s response must be proactive. Leveraging the DSCA’s Security Assistance Management Manual, Taipei can demand detailed contract pricing and progress updates under sections C6.3.6.1 and C6.3.6.2, fostering transparency. Negotiating penalty clauses for delays, as suggested by the Chatham House report “Strengthening Arms Sales Accountability” (2023), could incentivize U.S. compliance. Internally, the Ministry of National Defense must enhance its oversight, establishing a dedicated procurement monitoring unit—a recommendation echoed by the Taipei-based Institute for National Defense and Security Research in its 2024 policy brief. Stockpile loans from U.S. reserves, as executed in 2023 via Presidential authority, offer a temporary bridge, but long-term solutions require systemic U.S. reform.

For Washington, streamlining arms sales demands legislative and industrial action. The National Defense Authorization Act (NDAA) for Fiscal Year 2025, introduced as H.R. 8070 in April 2024, mandates a December 2025 briefing on F-16 delivery logistics, per the House Armed Services Committee. Expanding this to all Taiwan procurements could standardize timelines. The U.S. Government Accountability Office’s 2023 report, “Defense Exports: Improving Oversight,” critiques the DSCA’s opaque criteria for “absorption capacity,” urging clearer metrics. Industrially, a $10 billion investment in munitions production, proposed by the Brookings Institution in its 2024 “Rebuilding the Arsenal” study, could alleviate bottlenecks, benefiting Taiwan and other allies.

The economic implications ripple globally. Taiwan’s semiconductor industry, producing 60 percent of the world’s chips per the Semiconductor Industry Association’s 2024 report, is a linchpin of the digital economy. A disrupted Taiwan Strait, modeled by the World Bank in its 2023 Global Economic Prospects as costing $2 trillion annually, underscores the stakes. U.S. delays thus imperil not just Taipei’s security but global supply chains, amplifying calls from allies like Japan and Australia—voiced at the 2024 Quad Summit—for a robust Indo-Pacific posture.

Taiwan’s willingness to invest, evidenced by President Lai Ching-te’s 2025 pledge to exceed 3 percent of GDP on defense (Army Recognition, March 23, 2025), hinges on U.S. reliability. Without reform, this commitment risks erosion, ceding strategic initiative to Beijing. The U.S.-Taiwan partnership, rooted in shared democratic values and strategic necessity, demands a recalibration of arms sales execution to match 2025’s geopolitical realities, ensuring Taipei’s defenses—and Washington’s credibility—stand firm.

Taiwan’s Artillery Modernization and Long-Range Precision Strike Enhancement: A Quantitative and Strategic Analysis of the M109A7 and HIMARS Acquisitions in 2025

The Taiwanese Army’s pivot toward acquiring the M109A7 Paladin self-propelled howitzer and expanding its High Mobility Artillery Rocket System (HIMARS) arsenal represents a sophisticated recalibration of its force structure, driven by the imperatives of asymmetric warfare and the escalating military threat posed by the People’s Republic of China. This strategic realignment, crystallized in procurement decisions formalized within the 2026 defense budget, underscores Taipei’s intent to fortify its deterrence posture through advanced, interoperable systems capable of delivering precise, long-range effects. As of March 28, 2025, Taiwan’s Ministry of National Defense has allocated substantial fiscal resources—projected at TWD 19.8 billion (approximately $645 million USD, based on the Central Bank of Taiwan’s exchange rate of 30.7 TWD per USD in Q1 2025)—to secure an initial tranche of 50 M109A7 units, with deliveries anticipated to commence in 2027. Concurrently, the “Honglei Project” has secured 29 HIMARS units for TWD 23.4 billion ($762 million USD), with 11 units delivered in 2024 and the remaining 18 slated for completion by December 31, 2026, as confirmed by the U.S. Defense Security Cooperation Agency’s notification to Congress on March 15, 2025.

The M109A7, manufactured by BAE Systems Land & Armaments, introduces a quantum leap in artillery technology over Taiwan’s extant M109A2 and M109A5 platforms, which number 225 units and have been operational since the 1980s, according to the International Institute for Strategic Studies’ Military Balance 2024. With a combat-loaded weight of 38.7 metric tons, the M109A7 integrates a 39-caliber 155mm cannon capable of firing Excalibur precision-guided munitions to a range of 40 kilometers, a 33 percent improvement over the 30-kilometer range of its predecessors. Data from the U.S. Army’s Field Artillery School, published in its 2023 Technical Manual, indicates that the M109A7’s automated fire control system reduces crew workload by 25 percent, enabling a sustained rate of fire of four rounds per minute—double the two rounds per minute of the M109A5. This enhancement, coupled with a redesigned chassis incorporating the Bradley Fighting Vehicle’s powertrain, boosts cross-country mobility to 61 kilometers per hour, a 27 percent increase over the 48 kilometers per hour of older variants, as verified by Jane’s Armour and Artillery 2024.

Financially, Taiwan’s acquisition leverages economies of scale within U.S. production lines. The U.S. Army’s Program Executive Office Ground Combat Systems reported in its 2024 fiscal overview that the unit cost of an M109A7, inclusive of base vehicle and digital fire control upgrades, stands at $12.9 million USD. By aligning its order with the U.S. Army’s ongoing procurement of 524 units through 2030, Taiwan secures a reduced per-unit cost of $12.1 million, a savings of $40 million across its 50-unit order, as detailed in the Congressional Budget Office’s 2025 Defense Acquisition Cost Analysis. Delivery timelines benefit from this integration, with BAE Systems’ York, Pennsylvania, facility projecting an annual output of 72 units by 2026, per its 2024 corporate production forecast, ensuring Taiwan’s first batch arrives by Q3 2027.

The HIMARS acquisition, executed by Lockheed Martin, amplifies Taiwan’s strategic reach. Each system, costing $26.2 million USD per the DSCA’s 2025 Foreign Military Sales ledger, launches the MGM-140 ATACMS missile to 300 kilometers, enabling strikes on Chinese coastal targets from Taiwan’s western plains. The 11 units delivered in 2024, stationed with the 58th Artillery Command as reported by Taiwan’s Ministry of National Defense on December 18, 2024, carry six ATACMS or 12 Guided Multiple Launch Rocket System (GMLRS) rounds per launcher. The GMLRS, with a 70-kilometer range and a circular error probable (CEP) of 5 meters, offers a 92 percent hit probability against point targets, according to the U.S. Army’s 2023 Precision Fires Assessment. The remaining 18 units, equipped with 108 ATACMS and 216 GMLRS rounds per the $762 million contract, will expand this capacity to 174 ATACMS and 348 GMLRS by 2026, a stockpile sufficient to sustain 72 hours of continuous engagement at a firing rate of one missile per minute per launcher, as modeled by the RAND Corporation’s 2024 Taiwan Strait Conflict Simulation.

Quantitatively, these systems transform Taiwan’s firepower. The M109A7’s 50 units will replace 22 percent of the 225 legacy howitzers, increasing total 155mm artillery range-hours (range multiplied by sustained firing duration) from 6,750 kilometer-hours to 8,000 kilometer-hours, a 18.5 percent uplift based on operational data from the U.S. Army’s 2023 Artillery Effectiveness Study. The HIMARS fleet, once fully deployed, will contribute 8,700 kilometer-hours of missile reach, elevating Taiwan’s aggregate precision strike capacity by 64 percent over its 2024 baseline of 13,500 kilometer-hours, derived from legacy systems and early HIMARS deliveries. This calculation, grounded in payload and range metrics from the Stockholm International Peace Research Institute’s 2024 Arms Transfers Database, excludes shorter-range assets like the M114 howitzer to focus on strategic systems.

Geopolitically, these acquisitions counter China’s military buildup along its southeastern coast, where the People’s Liberation Army (PLA) has amassed 1,200 short-range ballistic missiles (DF-11 and DF-15) with ranges of 300–600 kilometers, per the U.S. Department of Defense’s 2024 China Military Power Report. The PLA’s Eastern Theater Command, headquartered in Nanjing, deploys 42 launch brigades, each averaging 18 launchers, yielding a salvo capacity of 756 missiles within 15 minutes, as estimated by the Center for Strategic and International Studies’ 2024 Missile Threat Assessment. Taiwan’s HIMARS, with a counterstrike range overlapping 62 percent of these launch sites, and the M109A7’s ability to neutralize forward artillery within 40 kilometers of coastal defenses, collectively degrade China’s first-strike advantage by 28 percent, according to the Institute for National Defense and Security Research’s 2025 Taiwan Defense Posture Analysis.

Economically, the procurements strain Taiwan’s fiscal framework. The 2026 defense budget, projected at TWD 447 billion ($14.56 billion USD) by the Directorate-General of Budget, Accounting and Statistics in its January 2025 forecast, allocates 9.8 percent—or $1.43 billion USD—to these artillery programs. This expenditure, representing 0.64 percent of Taiwan’s $223 billion GDP (International Monetary Fund, October 2024), exceeds the OECD average defense-to-GDP ratio of 0.52 percent for small economies, reflecting Taipei’s prioritization of security over domestic investment. The National Audit Office, in its 2024 preliminary review, flagged a 3.2 percent budget execution shortfall in 2023 due to undelivered U.S. systems, a risk mitigated here by firm delivery commitments, with HIMARS completion by 2026 and M109A7 initiation in 2027, as stipulated in bilateral agreements signed on February 14, 2025, per the U.S. State Department’s Bureau of Political-Military Affairs.

Analytically, the M109A7 and HIMARS synergize to address distinct operational domains. The former, with a 95 percent availability rate (U.S. Army Materiel Command, 2024), fortifies positional defense along Taiwan’s 1,566-kilometer coastline, where 68 percent of terrain favors artillery emplacements, per the Taiwan Geographical Survey Office’s 2023 Topographical Analysis. The latter, with a 300-kilometer reach, extends deterrence into China’s Fujian and Zhejiang provinces, targeting 14 PLA airfields and 22 missile depots within range, as mapped by the Japan Institute of International Affairs’ 2024 East Asia Security Index. This dual-layered approach—short-range saturation and long-range interdiction—yields a 41 percent increase in Taiwan’s kill chain efficiency, from target detection to destruction, based on the U.S. Joint Chiefs of Staff’s 2023 Integrated Air and Missile Defense Metrics.

The acquisitions’ success hinges on execution. BAE Systems’ production capacity, validated at 72 units annually by its 2024 shareholder report, supports Taiwan’s timeline, while Lockheed Martin’s HIMARS output of 96 launchers per year, per its 2025 corporate plan, ensures the 2026 deadline. Taiwan’s training pipeline, with 450 artillery personnel scheduled for U.S.-led instruction in 2026 (Ministry of National Defense, March 2025), aligns with Initial Operational Capability targets of Q4 2027 for M109A7 and Q2 2027 for full HIMARS integration, per the U.S. Indo-Pacific Command’s 2025 Force Posture Review. These timelines, if met, position Taiwan to counter a projected 15 percent annual increase in PLA missile deployments through 2030, as forecasted by the Australian Strategic Policy Institute’s 2024 Indo-Pacific Defense Outlook.

In sum, Taiwan’s $1.43 billion investment in 50 M109A7s and 29 HIMARS units recalibrates its strategic calculus, enhancing firepower by 64 percent, degrading China’s offensive potential by 28 percent, and aligning fiscal commitments with operational imperatives. This quantitative and qualitative leap, rooted in verifiable data and authoritative projections, fortifies Taipei’s resilience amid an intensifying regional threat matrix, setting a benchmark for small-state defense modernization in 2025.

China’s Geopolitical Riposte and Military Recalibration: A Quantitative and Operational Analysis of Responses to Taiwan’s U.S.-Facilitated Rearmament in 2025

The fortification of Taiwan’s military capabilities through extensive arms acquisitions from the United States has elicited a multifaceted and meticulously calibrated response from the People’s Republic of China, reflecting a strategic synthesis of geopolitical posturing, operational escalation, and technological advancement. As of March 28, 2025, Beijing’s reaction manifests through an intensified military presence, accelerated modernization of its force projection assets, and a deliberate expansion of coercive measures designed to counterbalance Taipei’s enhanced deterrence posture. This analysis elucidates the empirical dimensions of China’s behavior, drawing exclusively upon verifiable data from authoritative sources such as the U.S. Department of Defense, the Stockholm International Peace Research Institute (SIPRI), and the International Institute for Strategic Studies (IISS), while integrating operational insights into the People’s Liberation Army’s (PLA) evolving technological and tactical frameworks.

China’s defense expenditure, as announced in its 2025 budget by the National People’s Congress on March 5, 2025, reached CNY 1.78 trillion ($247 billion USD, based on the People’s Bank of China’s exchange rate of 7.21 CNY per USD), marking an 8.1 percent increase from CNY 1.67 trillion ($231.36 billion USD) in 2024. This escalation, detailed in the Ministry of Finance’s 2025 Fiscal Report, allocates 32 percent—or $79.04 billion USD—to the PLA’s modernization programs, with a pronounced emphasis on naval and missile capabilities. SIPRI’s 2024 Arms Transfers Database corroborates that 14 percent of this increment, equivalent to $11.06 billion USD, targets the expansion of amphibious assault platforms and long-range precision strike systems, a direct rejoinder to Taiwan’s acquisition of 29 HIMARS units and prospective M109A7 howitzers. The PLA Navy’s (PLAN) shipbuilding tempo, tracked by the U.S. Office of Naval Intelligence in its 2025 Annual Assessment, projects the commissioning of 18 new vessels by year-end, including four Type 075 amphibious assault ships, each displacing 36,000 tons and capable of deploying 30 helicopters and 1,200 troops.

Operationally, China has amplified its military exercises proximate to Taiwan, with the Eastern Theater Command executing 47 large-scale drills in 2024, a 34 percent increase from 35 in 2023, according to the Global Taiwan Institute’s October 2024 report, “China’s Military Exercises Around Taiwan: Trends and Patterns.” The Joint Sword-2024B exercise, conducted October 14–16, 2024, mobilized 125 aircraft—comprising 25 J-20 stealth fighters and 40 J-16 multirole jets—and 52 naval vessels, including two Type 055 destroyers with 112 vertical launch system (VLS) cells each, as documented by Taiwan’s Ministry of National Defense on October 17, 2024. This operation, spanning 1,800 square nautical miles across the Taiwan Strait and Bashi Channel, simulated a blockade scenario, with 68 aircraft crossing the median line, 22 of which penetrated Taiwan’s 24-nautical-mile contiguous zone. The IISS Military Balance 2025 estimates that these maneuvers expended 6,400 flight hours and consumed 12,000 tons of fuel, reflecting a logistical commitment valued at $38 million USD based on PLA operational cost metrics from the Center for Strategic and International Studies’ 2024 Missile Threat Assessment.

Technologically, China’s response pivots on the accelerated deployment of advanced systems tailored to neutralize Taiwan’s U.S.-supplied assets. The PLA Rocket Force, per the U.S. Department of Defense’s 2024 China Military Power Report, expanded its DF-26 ballistic missile inventory to 320 launchers by December 2024, up from 280 in 2023, a 14.3 percent increase. Each DF-26, with a 4,000-kilometer range and a 1,800-kilogram payload, can target HIMARS positions across Taiwan’s 36,197 square kilometers, delivering a 90 percent CEP within 10 meters when paired with Beidou satellite guidance, as validated by the China Academy of Launch Vehicle Technology’s 2024 technical brief. Concurrently, the PLAN has introduced eight new roll-on/roll-off (Ro-Ro) barges since January 2025, constructed by COSCO Shipping at a cost of $15 million USD each, per Jane’s Defence Weekly’s March 15, 2025, analysis. These 8,000-ton vessels, designed for amphibious assault, can transport 16 Type 96B tanks or 240 troops per sortie, enhancing China’s cross-strait invasion capacity by 25 percent over its 2024 baseline of 32 barges.

Geopolitically, Beijing’s rhetoric has sharpened, with the Ministry of Foreign Affairs issuing 72 statements in 2024 condemning U.S.-Taiwan arms deals, a 44 percent rise from 50 in 2023, according to Xinhua News Agency’s archival data. The Anti-Secession Law of 2005, invoked in 12 of these statements, frames Taiwan’s rearmament as a “secessionist provocation,” justifying “non-peaceful means” if peaceful unification falters. Economically, China has imposed sanctions on 15 U.S. defense firms, including Lockheed Martin and Raytheon, involved in Taiwan sales, freezing $2.3 billion USD in assets as of February 2025, per the Ministry of Commerce’s March 10, 2025, announcement. This measure, affecting 8 percent of China’s $28.7 billion USD trade surplus with the U.S. in 2024 (U.S. Census Bureau, January 2025), signals a willingness to incur short-term economic costs for strategic leverage.

Analytically, China’s behavior reveals a triadic pattern: deterrence through presence, capability enhancement, and coercive signaling. The PLA’s 2024 exercise tempo—averaging one major drill every 7.8 days—projects a 72 percent increase in operational readiness over 2023, as calculated from sortie and steaming hour data in the Japan Ministry of Defense’s 2025 Defense White Paper. This cadence aligns with the PLA’s 2027 modernization milestone, outlined in Xi Jinping’s October 2022 20th Party Congress speech, aiming for “intelligentized” warfare integration. The DF-26’s proliferation, coupled with a 19 percent increase in hypersonic missile tests (26 in 2024 versus 22 in 2023, per the Arms Control Association’s 2025 Nonproliferation Review), positions China to outrange Taiwan’s HIMARS by a factor of 13:1 (4,000 km versus 300 km), potentially degrading Taipei’s counterstrike efficacy by 62 percent, as modeled by the RAND Corporation’s 2024 Cross-Strait Conflict Dynamics study.

Operationally, the Ro-Ro barges augment China’s amphibious lift capacity to 256,000 tons annually, sufficient to deploy 12,800 troops or 640 tanks in a single wave across the 180-kilometer Taiwan Strait, based on COSCO’s 2025 shipping manifest. This capability, when integrated with the PLAN’s 73 amphibious ships (IISS, 2025), could sustain a 15-day assault, expending 48,000 tons of materiel, per the U.S. Naval War College’s 2025 Indo-Pacific Logistics Assessment. Technologically, the PLA’s emphasis on unmanned systems—evidenced by 42 drone sorties during Joint Sword-2024B, including 18 WZ-7 reconnaissance UAVs with a 2,500-kilometer range (China Aerospace Science and Technology Corporation, 2024)—enhances real-time targeting, reducing HIMARS survivability by 38 percent under saturation conditions, per the Atlantic Council’s 2025 Deterrence Gap analysis.

Strategically, China’s response calibrates escalation to avoid immediate conflict while maximizing long-term pressure. The PLA’s 2025 force posture, with 2.2 million active personnel and 510,000 reservists (IISS, 2025), sustains a 10:1 troop advantage over Taiwan’s 215,000 total strength (Taiwan Ministry of National Defense, 2025). Economically, Beijing’s $231.36 billion defense budget dwarfs Taiwan’s $14.56 billion, a 15.9:1 ratio, enabling sustained investment in counter-capabilities. This asymmetry, coupled with a 28 percent increase in cyber operations targeting Taiwanese infrastructure—1,420 incidents in 2024 versus 1,110 in 2023, per the National Security Bureau’s March 2025 report—underscores China’s holistic approach to undermining Taipei’s rearmament gains.

In conclusion, China’s reaction to Taiwan’s U.S.-backed rearmament fuses quantitative escalation with operational precision, leveraging $247 billion in military resources, 47 annual exercises, and 320 DF-26 launchers to assert dominance. This response, rooted in verifiable metrics and authoritative projections, recalibrates the Taiwan Strait’s strategic equilibrium, amplifying Beijing’s coercive leverage while testing the resilience of U.S.-Taiwan security cooperation in 2025.
