U.S. Aerospace and Defense C-Class Parts Market: Supply Chain and Demand Forecast to 2030

U.S. Aerospace and Defense C-Class Parts Market: Supply Chain and Demand Forecast to 2030
The U.S. aerospace and defense C-class parts market, valued at $16.8 billion in 2022, is anticipated to grow substantially, reaching $29.4 billion by 2030, according to a recent report by DataM Intelligence. This expansion is underpinned by strong demand across commercial, military, and general aviation sectors, alongside ongoing innovations in supply chain management and strategic industry initiatives.
Market Dynamics and Strategic Developments
The sector is undergoing significant transformation as original equipment manufacturers (OEMs) and suppliers prioritize supply chain resilience and operational efficiency. In October 2025, Boeing expanded its procurement program for C-class fasteners and consumables, aiming to bolster supply chain robustness across its defense platforms. Similarly, Lockheed Martin forged partnerships with U.S. suppliers in September 2025 to digitize inventory management for C-class components, thereby enhancing aircraft maintenance efficiency.
The U.S. Department of Defense has also committed resources to automated inspection technologies designed to improve quality control of small yet critical aerospace hardware. These efforts reflect a broader industry trend toward digitalization and automation, addressing supply chain bottlenecks and adapting to fluctuating demand patterns.
Industry Consolidation and Competitive Landscape
The market is witnessing increased consolidation as OEMs streamline their supplier bases and adopt platform-based standardization for C-class parts, which encompass fasteners, bearings, electronic components, and machined parts. Wesco Aircraft, now integrated into Incora, continues to pursue vertical integration with a focus on supplier consolidation and just-in-time delivery. TriMas Corporation’s acquisition of Omega Fasteners has further reinforced its position in specialty fastening systems, which are vital to commercial aviation supply chains.
Competitive dynamics are also shaped by companies such as Leonardo DRS, which anticipates a stable germanium supply and robust demand for counter-unmanned aerial systems (C-UAS). Additionally, bilateral agreements and strategic expansions involving firms like Airlink and Air Austral highlight the critical role of supplier contracts and resilience planning, as emphasized by forecasts from the Aviation Week Intelligence Network.
Product Innovation and Supply Chain Optimization
Leading industry players—including Amphenol Corporation, Eaton Aerospace, Arconic Corporation, Lisi Aerospace, LMI Aerospace, National Aerospace Fasteners Corporation, RBC Bearings, Stanley Black & Decker, and TriMas—are investing heavily in product innovation and supply chain enhancements. Noteworthy advancements include the introduction of lightweight aerospace-grade rivets by Stanley Engineered Fastening, which reduce weight by 20% while increasing durability for next-generation platforms. Boeing Distribution has implemented AI-based predictive analytics to optimize inventory forecasting, thereby improving readiness and supply chain resilience.
Furthermore, vendor-managed inventory (VMI), auto-replenishment, and pre-certified batch sourcing are increasingly adopted by Tier 1 and Tier 2 suppliers to meet stringent production timelines and quality standards.
Market Segmentation and Regional Outlook
The market is segmented by part type—including fasteners, bearings, electronic components, machined parts, and others—as well as by end-user categories such as commercial, military, general aviation, and others. Distribution channels are divided between OEM and aftermarket suppliers. North America commands the largest regional share at 38%, driven by the presence of industry leaders like Boeing and Lockheed Martin, whose market capitalization and performance remain closely monitored by investors and analysts.
Challenges and Future Prospects
Despite promising growth prospects, the U.S. aerospace and defense C-class parts market faces challenges including supply chain bottlenecks, geopolitical tensions, and demand volatility. The industry’s ongoing emphasis on digitalization, supplier consolidation, and resilience planning is expected to mitigate these risks and support sustained expansion through 2030.
