Aerospace & Defense Precision Castings Market Size, Ownership and Forecast 2025-2030: An $8.0 Billion Market Being Re-Divided by OEM Control

Merchant aerospace and defense precision castings revenue was about $8.0 billion in 2025 and grows to $11.2 billion by 2030 at a 7.0% CAGR in the base case, while GE Aerospace's agreement to acquire CPP would move about one-sixth of it under engine-maker ownership at close.

Merchant suppliers of aerospace and defense precision castings earned about $8.0 billion in 2025 (modelled range $6.8-9.4 billion). In this report's base case the market grows at a 7.0% CAGR to $11.2 billion by 2030.

On September 8, 2026, GE Aerospace agreed to acquire Consolidated Precision Products (CPP) for $11.75 billion. Close is expected in the second half of 2027, subject to regulatory approvals.

The report argues that value in this market is now set by control of yield-bounded single-crystal and directionally solidified casting capacity, not by aircraft build rates. Engine makers are buying, funding and building foundries, while gas turbines for data-centre power bid for the same capacity.

The 80-page report sizes the market by application, by end market and by ownership mode (independent and OEM-owned merchant revenue, with OEM-funded and captive capacity shown as indicators). It carries gas-turbine hot-section castings as a separate line. It profiles 12 companies, including Precision Castparts, Howmet Aerospace, CPP and Doncasters and the captive foundries of Pratt & Whitney, Rolls-Royce and Safran. It includes 20 charts and figures, 15 data tables, three forecast scenarios, a sensitivity analysis and a contraction stress test, with a forecast to 2030 and a scenario extension to 2035.

Report Highlights:

• The Price of Priority: On this report's reading, the price GE Aerospace agreed for CPP buys priority on scarce capacity more than earnings. The $11.75 billion values CPP at about 26 times its standalone 2027 EBITDA. At close, the purchase moves about one-sixth of the $8.0 billion merchant aerospace and defense castings market under engine-maker ownership.
• Market Size and Forecast: Merchant aerospace and defense precision castings revenue was about $8.0 billion in 2025, within a modelled range of $6.8-9.4 billion. In the base case it grows to $11.2 billion by 2030, a 7.0% CAGR. The report forecasts conservative and optimistic cases beside the base case, year by year to 2030, and extends all three to 2035. Its conservative case sits close to the 3.9-4.2% that the specialist aircraft engine casting reports forecast.
• The Second Bidder: Gas turbines are a second bidder for the same foundries. Industrial gas turbine work was 42% of Doncasters' 2025 revenue against 35% for aerospace, and 22% of Howmet's $4.3 billion Engine Products segment. The report sizes gas-turbine hot-section castings as a separate line, from 2025 to 2030.
• An Ownership Spectrum: Engine makers are taking control of casting capacity along a spectrum, not in one step. Pratt & Whitney is expanding its Asheville turbine-airfoil plant, Rolls-Royce plans to double output at its Rotherham blade-casting facility by 2030, Safran's Rennes turbine-blade foundry opens in 2027, and OEM capital is flowing into Doncasters, an independent, which cites up to 80% customer contribution to capital investment in its strategic partnerships.
• Airfoils, Not Airframes: The squeeze is set by airfoils, spares and gas turbines, not by airframes: Airbus described its engine supply as normalized in July 2026. In 2020, Howmet's Engine Products and PCC's revenues each fell by about 28-29%. The report's contraction stress test applies a shock on that scale to the 2025 merchant pool.

This report will provide answers to the following questions:

• Who will control qualified casting capacity through 2030, and on what terms?
• How large is the merchant aerospace and defense precision castings market in 2025, and how is it forecast to grow under base, conservative and optimistic cases to 2030 and 2035?
• What does GE Aerospace's agreement to acquire CPP price, and what could antitrust review change?
• How is merchant revenue split between independent and OEM-owned suppliers, and how far have OEM-funded and captive foundries advanced?
• How much do gas turbines for power generation compete with aerospace for the same single-crystal capacity?
• What limits casting capacity: yield, qualification or machine-tool lead times?
• How exposed is the market to a demand shock on the scale of 2020?

Methodology

Our analysis originates from primary research - direct interviews with executives, operators, and technical practitioners actively shaping these markets. This fieldwork provides access to perspective and data not available in secondary sources: what decision-makers are observing in real time, the problems driving purchasing behavior, and where they see value migrating. Every data point and claim undergoes human verification before inclusion; figures that cannot be substantiated or traced to credible sources are excluded.

Market sizing triangulates across multiple independent estimation methods, producing investment-grade estimates with assumptions documented explicitly so readers can evaluate the underlying logic, stress-test key inputs, and defend the numbers in boardrooms and diligence processes. We validate quantitative claims against peer-reviewed research, regulatory filings, and observable market signals - including systematic searches for contradicting evidence. Where methods produce divergent estimates, we investigate the source of variance and report ranges rather than false precision. Forecasts are constructed through scenario modeling anchored to base rates from comparable markets. (While every effort has been made to ensure accuracy, forward-looking statements reflect current expectations and are subject to risks, uncertainties, and assumptions that may cause actual results to differ materially.)

The result is thesis-driven analysis that delivers clear conclusions: specific enough to cite, transparent enough to verify, comprehensive enough to satisfy diligence requirements, and rigorous enough to withstand the follow-up question.
