Aerospace and defense C-class parts are small, low-cost components essential for the assembly and operation of larger systems. Although individually low in value, they are purchased in large quantities and play a crucial role in ensuring overall system reliability. Proper management of these parts is key to maintaining production schedules and controlling costs.
The main product categories in the aerospace and defense C-class parts market include fasteners, bearings and bushings, seals and gaskets, electrical and electronic components, fluid system parts, standard hardware, and machined precision components. Aerospace fasteners are high-strength, lightweight mechanical elements designed to securely join aircraft components while meeting strict performance and safety requirements. These fasteners are produced from various materials such as aluminum, steel, titanium, composites, and others, and are employed across numerous applications including engines, aerostructures, interiors, equipment, systems support, and avionics. These components are distributed through multiple channels, including original equipment manufacturers (OEMs) and aftermarket suppliers, and are used by a range of end users in commercial aviation, military and defense sectors, spacecraft manufacturing, and more.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
Tariffs on metals, fasteners, bearings, and electronic components used in aerospace and defense C-class parts have increased procurement costs and disrupted supply chains, especially for manufacturers relying on imports from Asia-Pacific and Europe. Engine, aerostructure, and avionics-related C-class components are the most affected segments due to their high-volume consumption. Despite these challenges, tariffs are encouraging domestic manufacturing, supplier diversification, and reshoring initiatives, which may strengthen long-term supply resilience and reduce dependency on foreign sources.

These aerospace and defense C class parts market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.
The aerospace and defense c class parts market size has grown strongly in recent years. It will grow from $18.02 billion in 2025 to $19.18 billion in 2026 at a compound annual growth rate (CAGR) of 6.4%. The growth in the historic period can be attributed to high-volume procurement of low-cost components for aerospace assembly, reliance on standardized C-class parts to ensure system compatibility, increasing outsourcing of non-critical components to reduce production costs, implementation of inventory management systems for small parts, rising demand for replacement and maintenance parts in defense fleets.
The aerospace and defense c class parts market size is expected to see strong growth in the next few years. It will grow to $24.33 billion in 2030 at a compound annual growth rate (CAGR) of 6.1%. The growth in the forecast period can be attributed to adoption of automated procurement and supply chain management for C-class parts, growing focus on cost optimization through vendor consolidation, integration of digital tracking and IoT-enabled monitoring for parts usage, expansion of aftermarket services and consumable parts support, rising production of advanced aircraft and defense systems driving demand for small components. Major trends in the forecast period include rising demand for high-volume procurement of standardized c-class parts, increasing focus on supply chain optimization to reduce production delays, growing adoption of lightweight materials for next-generation aircraft, higher emphasis on quality control to prevent failures in critical assemblies, expansion of aftermarket distribution networks for rapid parts fulfillment.
The growing demand for aircraft is anticipated to drive the expansion of the aerospace and defense C-class parts market. Aircraft, which include airplanes, helicopters, drones, and gliders, serve various purposes such as transportation, military, commercial, and recreational uses. This rising demand is mainly due to an increase in air passenger traffic, prompting airlines to modernize and expand their fleets to accommodate more travelers and enhance operational efficiency. Aerospace and defense C-class parts play a crucial role in aircraft production by facilitating the efficient assembly and integration of key components like fasteners, bearings, and seals, which are essential for maintaining structural integrity and functionality. For example, in May 2025, Airbus SE, a French commercial aircraft manufacturer, reported a 4% rise in commercial aircraft deliveries in 2024 compared to 2023, with 766 aircraft delivered versus 735 the year before. Additionally, total commercial aircraft orders reached 2,094 in 2024, up significantly from 820 in 2022. Thus, the increasing demand for aircraft is contributing to the growth of the aerospace and defense C-class parts market.
Leading companies in the aerospace and defense C-class parts market are emphasizing strategic partnerships to improve supply chain efficiency and maintain steady component availability. Strategic partnerships involve companies combining their strengths and resources for mutual benefit and success. For instance, in June 2025, Pacamor Kubar Bearings (PKB), a US manufacturing firm, partnered with R A Rodriguez (UK) Ltd., a UK industrial manufacturing company, to launch a new series of aerospace miniature instrument bearings tailored for high-precision aerospace applications. These bearings offer enhanced performance, lighter weight, and greater reliability in critical systems such as satellites, space vehicles, cryogenics, gyroscopes, aircraft instruments, guidance systems, and flow control systems. Made from 440C stainless steel and FAA-certified, they come in multiple ABEC tolerance classes, withstand harsh environmental conditions, and have been validated in major aerospace projects including the James Webb Space Telescope and Mars 2020 Rover.
In October 2025, TransDigm Group, a US-based aerospace company, acquired Simmonds Precision Products for an undisclosed amount. The acquisition is intended to reinforce and expand TransDigm's presence in the aerospace and defense sector by incorporating highly engineered, proprietary components that offer substantial aftermarket value.
