Aerospace & Defense Industry Statistics: Military Spending & Aviation Data (2024)
Verified aerospace and defense industry statistics for 2024: $2,718B world military expenditure (SIPRI), $996B airline revenues (IATA), and key segment data.
The global aerospace and defence industry spans military procurement and spending, commercial aviation, and an expanding space economy. Two forces dominated 2024: defence budgets rising at the fastest pace in decades driven by geopolitical instability, and commercial air travel recovering to record-high passenger volumes.

Segment Highlights
| Segment | 2024 Scale | Trend |
|---|---|---|
| Defence & Military | $2,718B global spending | 10th consecutive year of real growth; fastest pace since 1988 |
| Commercial Aviation | $996B total airline revenues | Record high; up 9.7% from $908B in 2023 |
| European Defence | +14% spending growth in 2024 | Fastest regional growth rate globally |
Growth Drivers
- Elevated Geopolitical Tensions — The wars in Ukraine and the Middle East, plus rising great-power competition in the Indo-Pacific, are pushing defence budgets to their highest real levels since the Cold War. SIPRI noted 2024 was the steepest single-year rise since at least 1988.
- Commercial Air Travel Recovery — With 4.96 billion passengers in 2024, airline demand has surpassed pre-COVID peaks. Record passenger revenues of $744 billion are driving new aircraft orders and MRO (maintenance, repair and overhaul) investment.
- Next-Generation Platform Cycles — Multi-decade backlogs at Airbus and Boeing for fuel-efficient narrowbodies (A320neo, B737 MAX), plus military modernisation programmes (hypersonics, autonomous systems, sixth-generation fighters), sustain long-term demand.
- Space Economy Commercialisation — Launch frequency records, satellite broadband constellations (Starlink, Kuiper), and government lunar programmes are opening new aerospace growth vectors beyond traditional air and land.
Key Challenges
- Supply Chain Bottlenecks — Shortages in aerostructures, engines, and specialised components are constraining aircraft delivery rates at major OEMs despite record order backlogs.
- Skilled Labour Shortages — The sector faces acute deficits of aeronautical engineers, machinists, and licensed maintenance technicians as post-COVID hiring lags demand.
- Fixed-Price Contract Losses — Defence primes face material losses on fixed-price development contracts where inflation-driven cost growth outpaces locked-in contract values.
- Export Controls — Tightening controls on advanced electronics, propulsion technologies, and munitions complicate international programme access and global supply chains.

World military expenditure reached $2,718 billion in 2024 according to SIPRI, a real-terms increase of 9.4% from 2023 — the steepest single-year rise since at least 1988. Military spending represented 2.5% of global GDP in 2024.
IATA forecast global airline total revenues of $996 billion for 2024 — a record — with passenger revenues of $744 billion (+15.2% from 2023) and total passengers of 4.96 billion. Both figures represent all-time highs.
Europe recorded the fastest regional growth in defence spending in 2024 at +14%, driven by NATO member commitments following the war in Ukraine and rising threat perceptions across the continent.
Primary drivers include elevated geopolitical tensions lifting defence budgets, post-COVID recovery in commercial air travel, multi-decade aircraft replacement cycles at Airbus and Boeing, and the rapidly expanding space economy including commercial satellite constellations and government lunar programmes.
