Aerospace & Defense MRO Market Size, Share & Industry Analysis, By Market Domain (Commercial Aviation MRO, Defense Aviation MRO, Business & General Aviation MRO, and Others), By Aircraft Class, By MRO Service Type (Line Maintenance, Base Maintenance, Engine MRO, APU MRO, Component MRO, Digital MRO, and Others), By Maintenance Level, By Maintenance Event, By Defense Mission Systems (Radar Systems, Electronic Warfare, Weapons Interface, and Others), By Provider Type (OEM MRO, Airline-Affiliated MRO, Independent MRO, Authorized Service Center, and Others), and Regional Forecast 2026-2034

The global aerospace & defense MRO market size was valued at USD 183.75 billion in 2025. The market is projected to grow from USD 199.15 billion in 2026 to USD 300.66 billion by 2034, exhibiting a CAGR of 5.28% during the forecast period.

The aerospace & defense MRO sector covers maintenance, repair, overhaul, upgrades, spares, engineering support, logistics, and digital sustainment for commercial and military aircraft, engines, avionics, components, and mission systems. It is the market that ensures that the fleets are airworthy, mission-ready, and economically functional during their service life.

The global market growth is being propelled by higher flight activities, aging aircraft fleets, delayed new-aircraft deliveries, and immense pressure on airlines and militaries to extend asset life rather than to replace the platforms quickly. IATA reported a 5.3% growth in 2025 air travel demand, while SIPRI reported global military expenditure touched USD 2.887 trillion in 2025, both supporting a stronger civil and defense sustainment demand.

The major MRO companies include Boeing, Airbus Servies, Rolls-Royce plc, RTX/Pratt & Whitney–Collins Aerospace, and Lufthansa Technik.

Aerospace & Defense MRO Market Trend

Shift of MRO from Reactive Repair to Predictive, Digital, Additive, and Lifecycle-Based Sustainment

The market is moving toward connected sustainment, where operators use aircraft health data, digital work instructions, AI-based parts sourcing, automated inspection, additive aircraft maintenance repair and overhaul MRO to reduce downtime. AI-driven procurement that connects buyers to suppliers, consolidates quotes, analyzes supplier performance, and supports faster purchasing decisions through AAR’s Airvoyant launch exemplifies the future direction market is taking. . This kind of software directly addresses one of MRO’s major pain points that is slow and fragmented parts sourcing.

For instance, in May 2026, the U.S. Army’s official Army Sustainment issue focused on maintenance modernization, including predictive maintenance, cold spray, tele-maintenance, low-cost sensors, and AI-ready reporting.

Market Dynamics

Fleet Availability, Lifecycle Extension, and Defense Readiness Are Pushing The Demand for MRO

The aerospace & defense MRO market growth is being driven by fleets’ requirement to remain accessible even if the new aircraft deliveries, spare-parts flows, and defense fleet modernization are stretched. Boeing’s 2025–2044 services outlook reports that commercial aviation support and services amounted to USD 4.7 trillion, covering MRO, modifications, parts, supply chain, training, and digital solutions. Airbus reported that it also expects aviation services demand to grow strongly, reaching USD 311 billion by 2044. This shows that MRO is becoming a core fleet-availability and lifecycle-management business.

MARKET RESTRAINT

Shortages of Parts, Engine Material Constraints, and Cost Inflation Are Slowing Turnaround, Hampering the Service Demand

The market’s one of the biggest restraints is the ability to execute maintenance repairs and overhauls work on time and profitably. Engine MRO is especially affected as high-value parts, used serviceable materials, life-limited parts, castings, and repairable components remain in short supply across several programs. RTX’s Pratt & Whitney openly stated that material constraints are one of the main causes of delays in the MRO process, owing to this, the company is expanding used serviceable material stock and quick-turn capacity.

MARKET OPPORTUNITIES

Localized Sustainment, Regional MRO Hubs, and Digital Procurement to Unlock High-Value Growth

The strongest growth opportunity for the market is building MRO closer to the fleet operator, especially for defense customers that want sovereign or in-country sustainment. Local depots reduce dependency on overseas repair centers, shorten turnaround time, improve readiness, and support local industrial participation. This is particularly attractive in India, the Middle East, Southeast Asia, and Latin America, where defense modernization and commercial fleet growth are creating demand for local repair ecosystems.

For instance, in April 2026, GE Aerospace signed a contract with the Indian Air Force to help establish an in-country depot for F404-IN20 engines powering the Tejas LCA fleet.

MARKET CHALLENGES

Maintenance Challenges Associated With Older and Newer Aircraft is Hampering the Market Growth

The main challenge for the market growth is old and new aircraft becoming harder to sustain. Older aircraft require corrosion, fatigue, obsolete parts, and unplanned depot work and newer aircraft require software complexity, proprietary data, mission-system integration, and higher dependence on OEM technical support. GAO, on May 14^th, 2026, reported that U.S. Air Force depot maintenance delays have increased considerably since FY2019, and by FY2024 as 73% of aircraft were delayed against their original target completion date.
