United States Aerospace Parts Manufacturing Market Outlook to 2030: Size, Share, Growth and Trends

The United States Aerospace Parts Manufacturing Market was valued at USD 431,200 Mn in 2024. This figure reflects domestic manufacturer and Tier-1 supplier revenue across commercial aviation, defense, space, and business aviation parts production, while excluding pure MRO services and non-U.S. production. The scale is commercially significant because it captures both prime-integrated production and supplier-level value creation. Aerostructures remains the largest revenue pool, while propulsion and defense parts collectively keep the market diversified enough to withstand volatility in any single airframe program.

The market is projected to reach USD 545,800 Mn by 2030, implying a 4.0% CAGR during 2025-2030. That forecast is materially stronger than the historical 1.9% CAGR during 2019-2024, which was held back by the 2020 demand shock and a slower commercial production recovery. The forecast assumes more stable OEM execution, continued defense procurement support, and faster growth in higher-value electronics and space-adjacent content. In practical terms, the next growth cycle should be less dependent on simple volume rebound and more driven by richer mix and program complexity.

Profit is gradually shifting toward electronics-rich and mission-critical categories rather than low-growth cabin content. Avionics and Electronics is the fastest-growing segment at 5.8% CAGR, while Cabin Interiors is the slowest at 1.4%. This matters because avionics, EW hardware, autonomous control, and flight management systems typically carry higher value density, faster refresh cycles, and stronger pricing power than interiors or commodity structures. Aerostructures will remain the largest pool by revenue, but the marginal dollar of growth is increasingly likely to come from software-enabled, certified, and defense-linked content.

The largest forecast risk is execution disruption at major commercial and defense programs rather than end-demand collapse. Boeing delivered 348 commercial airplanes in 2024, but production instability and prior ramp interruptions kept many upstream suppliers below efficient utilization. On the defense side, concentration risk also matters, because the DoD highlighted in 2024 that 90% of missiles come from just three sources, revealing how narrow critical manufacturing capacity can become. If similar concentration persists across forgings, castings, electronics, or aerostructures, even healthy backlog may not translate into timely revenue recognition.

The United States is the clear scale leader among relevant peer aerospace manufacturing countries. At USD 431.2 Bn in 2024, it exceeds France, Germany, the United Kingdom, and Canada by a wide margin. The country's advantage comes from breadth, not just size: it combines commercial aircraft production, defense airframes, propulsion, avionics, and space hardware within one domestic manufacturing system. Growth is not the highest in the peer set, but the U.S. offers better backlog depth, more diverse end-market exposure, and a larger supplier ecosystem, which lowers cyclical concentration risk.

The market is fundamentally driven by installed platform demand and the need to sustain, replace, and upgrade high-value aerospace content over long production cycles. The FAA recorded a 7,387-aircraft U.S. commercial fleet in 2024, while Boeing reported a USD 521.3 Bn total backlog at year-end 2024. Together, those two indicators show why the market remains structurally durable: one anchors recurring platform-level parts demand, and the other secures multi-year visibility for new-build production. Defense and space programs then add a second demand pillar that is less correlated with airline profitability.
