Market Overview

The Global Aerospace & Defense C-Class Parts Market, valued at USD 12.40 Billion in 2024, is projected to experience a CAGR of 6.26% to reach USD 17.85 Billion by 2030. Global Aerospace & Defense C-Class parts are typically defined as high-volume, low-cost components, including fasteners, bearings, seals, and standard hardware, which are mission-critical for the intricate assembly and sustained operational functionality of aircraft and defense systems. The market's expansion is primarily driven by increasing global air travel demand, necessitating higher aircraft production rates, alongside ongoing military modernization programs and the robust maintenance, repair, and overhaul sector.

The continuous demand for new aircraft significantly underpins this market. According to the General Aviation Manufacturers Association (GAMA), general aviation aircraft deliveries across all segments exceeded 4,000 units in 2023, marking an increase over the prior year. A significant challenge impeding market growth remains the susceptibility of global supply chains to disruptions, including raw material price volatility and geopolitical instability, which can impact component availability and cost stability.

Key Market Drivers

Increased aircraft production and deliveries are a primary driver for the Global Aerospace & Defense C-Class Parts Market. Persistent growth in air travel fuels higher aircraft manufacturing rates, directly impacting the procurement of essential C-class components like fasteners, bearings, and seals integral to airframe, engine, and interior assemblies. As commercial airlines expand and renew their fleets, original equipment manufacturers consequently increase orders for these critical small parts. According to Airbus, in January 2024, their news release reported 735 commercial aircraft were delivered in 2023, an 11% increase over 2022. This upward trajectory in new aircraft output directly correlates with heightened demand for C-class parts across the aerospace supply chain.

Rising defense budgets and military modernization programs form another pivotal factor influencing the C-class parts market. Governments worldwide are investing substantially in upgrading existing defense platforms and acquiring new, advanced military aircraft and systems. This modernization involves both initial equipment builds and extensive maintenance, repair, and overhaul activities for extended operational lifespans, all necessitating a steady supply of precision C-class parts. According to the Stockholm International Peace Research Institute (SIPRI), in April 2024, their "Trends in World Military Expenditure, 2023" report stated that global military expenditure reached $2,443 billion in 2023, reflecting robust, sustained investment in defense capabilities. Additionally, according to SKF, in January 2024, their "Year-end report 2023" indicated their aerospace business grew around 20% in 2023, demonstrating healthy demand within a segment heavily reliant on these components.

Key Market Challenges

A significant challenge impeding the growth of the Global Aerospace & Defense C-Class Parts Market is the susceptibility of global supply chains to disruptions. These disruptions, encompassing raw material price volatility and geopolitical instability, directly impact the availability and cost stability of essential components. Such instability creates difficulties in securing a consistent supply of mission-critical, high-volume, low-cost C-Class parts like fasteners and bearings, which are fundamental to aerospace and defense manufacturing. For example, according to the Aerospace Industries Association, in 2023, the sector experienced an average delay of 8.5 weeks in the delivery of critical components.

These extended lead times and unpredictable costs directly hamper the production rates of new aircraft and the efficiency of maintenance, repair, and overhaul operations. When the supply of even minor components is constrained or their prices fluctuate unexpectedly, it causes delays in assembly lines and increases overall manufacturing expenses. This directly limits the ability of the market to meet demand from increasing air travel and military modernization programs. According to ADS Group, in the first half of 2024, aircraft deliveries fell 14% compared to the first half of 2023, with supply chain challenges identified as a contributing factor. This demonstrates how broader supply chain issues translate into reduced output, consequently restricting the expansion of the C-Class parts market.

Key Market Trends

Two distinct and significant trends shaping the Global Aerospace & Defense C-Class Parts Market are the digitalization of supply chain management and the increased adoption of advanced manufacturing technologies. These trends are critical for enhancing efficiency, resilience, and precision in component production and delivery.

The digitalization of supply chain management is profoundly transforming how C-Class parts are sourced, tracked, and delivered. This trend involves implementing advanced digital tools like blockchain, artificial intelligence, and predictive analytics to achieve end-to-end visibility, improve inventory control, and mitigate supply chain disruptions. Such digital transformation ensures greater transparency and efficiency in the complex global network that supplies critical small components. For instance, according to ePlaneAI, July 2025, in "Blockchain Enhances Aviation Through Supply Chain Security, Maintenance Logs, and Passenger Identity", Airbus collaborated with IBM in April 2025 to establish a blockchain-powered supply chain network for critical aircraft components, enhancing real-time visibility and preventing counterfeit parts. Given the expansive nature of this sector, according to the Aerospace Industries Association (AIA), in its 2024 "Facts & Figures" report based on 2023 data, nearly 60 percent of jobs in the U. S. aerospace and defense industry are directly linked to the supply chain, underscoring the vast impact of digital improvements across this critical infrastructure.

Another pivotal trend is the increased adoption of advanced manufacturing technologies. Innovations such as additive manufacturing (3D printing) are enabling the production of C-Class parts with complex geometries, reduced weight, and enhanced performance characteristics, alongside offering greater customization and faster lead times. These technologies are crucial for meeting stringent aerospace standards and the growing demand for more fuel-efficient and high-performance aircraft. According to GE Aerospace, March 2024, in "GE Aerospace to Invest Over $650M in Manufacturing Facilities, Supply Chain in 2024", the company announced plans to invest over $650 million in its manufacturing facilities and supply chain, allocating nearly $450 million for new machines, including additional additive (3D printing) equipment to boost production of engine components for military rotorcraft and commercial aircraft. The Aerospace Industries Association (AIA), in its 2024 "Facts & Figures" report, highlighted the robustness of the industry, with the U. S. aerospace and defense sector generating over $955 billion in sales in 2023, an output significantly supported by advancements in manufacturing capabilities.
