COMAC Cuts C919 2025 Delivery Targets Amid Production Challenges

COMAC’s C919 Aircraft Program: Production Challenges, Market Dynamics, and Strategic Implications for China’s Aviation Ambitions

China’s Commercial Aircraft Corporation (COMAC) is experiencing significant production shortfalls in its flagship C919 narrow-body aircraft program, with delivery targets slashed from an ambitious 75 aircraft in 2025 to just 25 units, while only five aircraft had been delivered by September 2025. This dramatic reduction in production goals highlights the complex challenges facing China’s aerospace ambitions, including supply chain vulnerabilities exposed by US export restrictions, reliance on Western-manufactured components, and the inherent difficulties of scaling aircraft production. The C919 program, which has consumed an estimated $8.6 billion in official development costs with actual expenses potentially reaching $15-20 billion, represents China’s most significant attempt to challenge the Boeing–Airbus duopoly in commercial aviation. Despite securing over 1,000 orders primarily from Chinese state-owned airlines and achieving operational status with 16 aircraft currently in service, COMAC’s production struggles underscore the strategic and technological hurdles that emerging aircraft manufacturers face in competing with established Western competitors. These developments carry profound implications for China’s industrial policy objectives, the global aviation supply chain, and the long-term competitive dynamics in the commercial aircraft market.

The C919’s journey encapsulates China’s broader ambitions to ascend the global technological value chain and reduce dependence on foreign aerospace technology. Its challenges and milestones are emblematic of the complexities inherent in building a world-class aviation industry from the ground up, especially in a sector dominated by entrenched players with decades of experience and established global supply chains.

Background and Development History of the C919 Program

The Commercial Aircraft Corporation of China (COMAC) was established as part of China’s strategic initiative to develop an indigenous commercial aviation industry capable of competing with established Western manufacturers. The C919 program emerged from China’s broader industrial policy objectives, representing a cornerstone of the nation’s efforts to move up the value chain in high-technology manufacturing sectors. The National Development and Reform Commission approved COMAC’s plan to develop the C919 as a large, single-body aircraft designed to compete directly with the Boeing 737 and Airbus A320 families.

COMAC received substantial financial backing from the Chinese government, with nearly $7 billion in initial seed capital provided through a combination of central and local governments, state-owned banks, and other state-owned enterprises. The scale of government support for the program has been unprecedented, with estimates suggesting that COMAC was granted access to nearly $72 billion in state subsidies through the end of 2020. However, COMAC’s annual reports indicate actual losses of only $3 billion since incorporation, suggesting that the company has used far less capital than it has had access to, potentially indicating strategic reserve building or phased capital deployment.

The development timeline of the C919 has been marked by both ambitious goals and significant delays. The aircraft was initially conceived as a means to capture market share in China’s rapidly growing domestic aviation market while simultaneously establishing a platform for eventual international expansion. The program’s development costs, officially stated at $8.6 billion, likely represent a conservative estimate, with independent assessments suggesting real costs may exceed $20 billion when accounting for delays, modifications, and the full scope of supporting infrastructure development. This investment scale places the C919 program among the most expensive aircraft development initiatives globally, comparable to or exceeding the costs associated with established programs from Boeing and Airbus.

The technical specifications and design philosophy of the C919 reflect China’s approach to entering the commercial aviation market through a combination of domestic capabilities and international partnerships. The aircraft incorporates significant content from Western suppliers, with critical systems including engines, avionics, and flight controls sourced from established aerospace companies. This approach was intended to leverage proven technologies while building domestic manufacturing capabilities, but has subsequently created strategic vulnerabilities as geopolitical tensions have intensified between China and Western nations.

The C919 achieved several significant milestones in its development trajectory, including its maiden flight in 2017 and subsequent entry into commercial service with China Eastern Airlines in December 2022. The aircraft received its airworthiness certification from the Civil Aviation Administration of China on September 29, 2022, marking a crucial step toward commercial operations. However, the program has continued to face challenges in scaling production and achieving international certification, with Western aviation regulators maintaining strict oversight of Chinese-manufactured aircraft.

Current Production Challenges and Delivery Shortfalls

COMAC’s current production challenges represent a significant departure from the ambitious targets initially established for the C919 program. The company’s delivery goals have undergone multiple revisions throughout 2025, reflecting the complex realities of aircraft manufacturing and external pressures affecting production capabilities. Initially, COMAC stated plans to deliver 30 C919 aircraft in 2025 while scaling up annual production capacity to 50 aircraft. These targets were subsequently raised to 75 aircraft in March 2025, according to Chinese media reports, suggesting initial optimism about production capabilities and market demand.

However, the reality of production has fallen dramatically short of these ambitious projections. By September 2025, COMAC had delivered only five C919 aircraft, prompting the company to slash its production target to 25 units for the full year. This represents a 67% reduction from the peak target of 75 aircraft and highlights the significant challenges facing the program. The shortfall has had direct implications for COMAC’s airline customers, with China Eastern Airlines, Air China, and China Southern collectively expecting 32 aircraft deliveries in 2025 but receiving far fewer than anticipated.

The production challenges extend beyond simple manufacturing capacity constraints to encompass broader supply chain and regulatory issues. COMAC faced unexpected disruptions when the United States temporarily halted exports of CFM LEAP-1C engines between June and July 2025 as trade tensions escalated. These engines, manufactured by CFM International (a joint venture between Safran and General Electric), are critical components of the C919, and their temporary unavailability directly impacted production schedules. While the export restrictions were subsequently lifted in July 2025, the disruption highlighted the vulnerability of COMAC’s supply chain to geopolitical developments.

Aviation consultancy IBA has provided more conservative projections for C919 deliveries, forecasting approximately 18 aircraft in 2025 and 25 in 2026, rising to about 45 in 2027. These projections suggest that COMAC’s production targets have been overly optimistic and that a more measured approach to production scaling may be necessary. The consultancy’s analysis indicates that COMAC’s ambitious targets failed to account for the complexities of aircraft manufacturing, including quality control requirements, supply chain coordination challenges, and the learning curve associated with scaling production.

“The gap between COMAC’s production ambitions and its actual output highlights the steep learning curve and supply chain dependencies that new entrants face in the global aerospace industry.”

Despite these challenges, COMAC has taken steps to address production constraints through facility expansion and capacity building initiatives. The company is constructing a second phase production facility in Shanghai’s Pudong district, with a total construction area of approximately 330,000 square meters and a budget of 11.955 billion RMB ($1.65 billion). This expansion is designed to support future mass production needs and enhance the commercial viability of the C919 program, though the timeline for bringing this additional capacity online remains uncertain.

Supply Chain Vulnerabilities and US Export Restrictions

The C919 program’s reliance on Western-manufactured components has emerged as a critical vulnerability, exposing COMAC to geopolitical risks and supply chain disruptions that directly impact production capabilities. The aircraft’s design incorporates substantial content from US and European suppliers, with critical systems including engines, avionics, flight controls, and other sophisticated components sourced from established aerospace companies. This dependency reflects both the technical complexity of modern commercial aircraft and the concentrated nature of the global aerospace supply chain, where a limited number of specialized suppliers dominate key market segments.

CFM International’s LEAP-1C engines represent the most visible and critical dependency in the C919 supply chain. These engines, produced through a joint venture between French company Safran and US-based General Electric, are specifically designed for the C919 and cannot be easily substituted with alternative powerplants. The temporary suspension of export licenses for these engines in 2025 demonstrated how quickly geopolitical tensions can translate into production disruptions for COMAC. While the restrictions were lifted after approximately one month, the incident highlighted the strategic vulnerability of China’s flagship aviation program to US export controls.

Beyond engines, the C919’s dependency on Western suppliers extends throughout its major systems. Leading US suppliers include GE Aerospace, Collins Aerospace, and Honeywell, which provide a wide range of critical systems from avionics to landing gear. This extensive reliance on Western technology means that export restrictions affecting any of these suppliers could potentially disrupt C919 production. COMAC has attempted to mitigate these vulnerabilities through strategic stockpiling of critical components, but these reserves are a short-term solution.

The development of domestic alternatives represents COMAC’s long-term strategy for addressing supply chain dependencies. The ACAE CJ-1000A engine, being developed as a domestic alternative to the LEAP-1C, represents the most significant effort in this direction. However, the CJ-1000A remains in flight testing and is not expected to be ready for commercial service until at least 2030. Even when available, the domestic engine will need to demonstrate performance and reliability characteristics comparable to established Western engines, a process that typically requires several years of operational experience.

“Supply chain vulnerabilities are not just a technical issue for COMAC, they are a strategic challenge that could define the long-term viability of China’s commercial aircraft ambitions.”

The broader implications of these supply chain vulnerabilities extend beyond immediate production impacts to encompass strategic questions about China’s aerospace industrial development. The US government’s evolving approach to export controls reflects a shift from purely commercial considerations to national security concerns, with officials stating that the United States seeks “as large of a lead as possible” in key technologies. This policy evolution suggests that supply chain restrictions may become more frequent and comprehensive over time, increasing pressure on COMAC to accelerate domestic substitution efforts.

Financial Analysis and Market Position

The financial structure and cost analysis of the C919 program reveal the substantial investment required to establish a competitive position in the global commercial aviation market. COMAC’s official development budget of $8.6 billion, announced in 2017, represents only a portion of the total investment in China’s commercial aviation capabilities. Independent assessments suggest that the true development costs, including delays, modifications, and supporting infrastructure, may approach $15-20 billion, placing the program among the most expensive aircraft development initiatives in aviation history.

The unit cost structure of the C919 presents significant challenges for COMAC’s commercial viability. Early estimates suggested that the aircraft would be available at a competitive price point of $50-60 million per unit, potentially offering a cost advantage over established competitors. However, current unit cost estimates range from $90-100 million per aircraft, with some reports indicating prices as high as $108 million for state-subsidized sales to Air China. This pricing structure places the C919 at or above the cost of comparable Boeing 737 MAX and Airbus A320neo aircraft, eliminating the anticipated cost advantage that was expected to drive market penetration.

COMAC’s domestic market strategy has achieved notable success, with the C919 securing over 1,000 orders from Chinese airlines and aircraft lessors, including major carriers such as Air China, China Eastern Airlines, and China Southern Airlines. Aviation consultancy Cirium projects that Chinese airlines will induct approximately 6,000 new single-aisle aircraft by 2042, with COMAC potentially capturing approximately 25% market share of these additions, compared to Boeing’s projected 30% and Airbus’s 45%. This market share projection suggests that the C919 can establish a viable position within China’s domestic market while Boeing and Airbus maintain their dominant positions.

International market expansion represents a more challenging proposition for COMAC, with the C919 facing significant regulatory, operational, and competitive hurdles. The aircraft currently lacks certification from major Western aviation regulators, including the FAA and the EASA, which is essential for international market access. EASA confirmed in April 2025 that validation of the C919 would require at least three to six years from the point of technical familiarization, indicating that international certification remains a medium-term objective rather than a near-term achievement.

“Airbus CEO Guillaume Faury has acknowledged COMAC as a ‘credible competitor,’ signaling a shift in the industry’s perception of China’s aerospace ambitions.”

The maintenance, repair, and overhaul (MRO) infrastructure represents another competitive challenge for COMAC’s international expansion efforts. Unlike Boeing and Airbus, which operate extensive global MRO networks, COMAC does not currently maintain overseas MRO centers. The company has indicated that it will initially rely on customers’ own MRO capabilities while offering to establish new MRO centers in countries where airlines purchase at least 30 aircraft. This approach may limit the aircraft’s appeal to airlines that prefer comprehensive manufacturer support services.

Conclusion

The COMAC C919 program represents a pivotal case study in the complexities of challenging established industries through state-directed industrial policy and substantial financial investment. The program’s mixed results to date, achieving domestic market acceptance while struggling with production scaling and international expansion, illustrate both the possibilities and limitations facing new entrants in the global commercial aviation market. The dramatic reduction in delivery targets from 75 to 25 aircraft in 2025, with only five units delivered by September, underscores the significant operational challenges that persist despite massive financial backing and strategic support.

The ongoing developments in COMAC’s production capabilities, international certification efforts, and market expansion will continue to provide newsworthy developments for industry observers. The company’s ability to resolve current production challenges and achieve its ambitious scaling targets will serve as important indicators of the program’s long-term viability and China’s success in developing competitive commercial aviation capabilities. As the aviation industry continues to recover from pandemic-related disruptions and adapt to evolving environmental and regulatory requirements, COMAC’s progress will remain an important factor in shaping the industry’s future competitive dynamics and strategic direction.
