Based on function, the global aerospace engineering services outsourcing market is divided into design, simulation and digital validation, production process, and maintenance process.

The maintenance process segment is responsible for the substantial market share and is expected to grow at a CAGR of 24.6% over the forecast period. The maintenance process segment includes the after-market functionalities and security and certification functions in the aerospace industry. The segment is gaining prominence due to increasing awareness about safety and airworthiness. Regulatory bodies and governments across the globe are continually focusing on environmental welfare and imposing stringent norms on the aerospace industry to safeguard the same.

Digitization and many connected devices have augmented the need for information assurance and cyber resilience. This has made it mandatory for the aerospace industry to ensure data security against cyber threats. Functions such as product support, predictive maintenance, and asset tracking and management have seen a surge in the aerospace sector. The increasing outsourcing of Maintenance, Repair, and Overhaul (MRO) processes will likely encourage the maintenance process segment to retain its dominance over the forecast period.

Based on location, the global aerospace engineering services outsourcing market is bifurcated into onshore and offshore outsourcing activities.

The onshore segment owns the highest market share and is anticipated to grow at a CAGR of 26.0% during the forecast period. The onshore outsourcing activity in the aerospace industry is developing rapidly owing to the security and authenticity promised. The onshore activity enables aerospace OEMs to partner with the ESP in their time zone and work in the same lawful jurisdiction. This allows easy and better-streamlined communication between the two firms, increasing the efficiency of outsourced services. In addition, the aerospace and defense sector is witnessing a Manufacturing-as-a-Service (MaaS) trend to diversify their supply chains. Onshoring MaaS can reduce delay possibilities and shipping outlays and ensure more competent designs. There has been an increase in onshoring of aerospace engineering services, especially in the Middle East and Africa region, to meet the growing demand for a reduction in transportation delays and costs.

Based on components, the global aerospace engineering services outsourcing market is divided into hardware and software.

The hardware segment is the highest contributor to the market and is projected to grow at a CAGR of 25.5% over the forecast period. The hardware segment comprising raw materials, forgings, castings, extrusions, parts, components, subassemblies, aero-structure, aero-engine, avionics, aircraft interiors, and all hardware modules required to build the aircraft and spacecraft, possesses the greatest market share and is anticipated to rule the market during the forecast period. The hardware component segment will likely hold the leading position over the forecast period owing to the rapid growth in electro-mechanical systems used in the aerospace industry.
