Is Mitsubishi Heavy Industries profitable in 2026?

Yes. For FY2025 (ended March 31, 2026) MHI reported profit attributable to owners of ¥332.1 billion, up 35.3% year over year, on record revenue of ¥4,974.1 billion and record order intake of ¥7,653.6 billion, per its May 12, 2026 results release.

Could AI replace Mitsubishi Heavy Industries?

No. MHI's core revenue comes from physical turbines, nuclear reactors, jets and ships that software cannot substitute. It uses AI internally via its TOMONI maintenance platform and, as of July 2026, sells cooling and power infrastructure to AI data centers with NVIDIA, making AI a revenue tailwind, not a threat.

Who is Mitsubishi Heavy Industries' biggest competitor?

In gas turbines, GE Vernova and Siemens Energy are named global rivals, though MHI won contracts like Intermountain Power Agency and Entergy in 2025. In defense, MHI is Japan's sole fighter manufacturer with no domestic peer; in launch vehicles SpaceX dominates over MHI's H3 rocket.

Who owns Mitsubishi Heavy Industries?

MHI is a publicly traded company (Tokyo Stock Exchange: 7011, also OTC as MHVYF) with no single controlling parent. It is a core member of the Mitsubishi Group keiretsu but is legally separate from Mitsubishi Corporation and Mitsubishi Electric.

What happened to Mitsubishi Heavy Industries' H3 rocket program?

H3 Launch Vehicle No. 8 suffered a second-stage failure in December 2025, suspected to be a manufacturing defect, halting launches. MHI and JAXA resumed flights with H3 Rocket No. 6, a booster-less configuration, around mid-July 2026, with QZS-7 planned next around August 6, 2026.

Does Mitsubishi Heavy Industries make fighter jets?

Yes. MHI is Japan's sole fighter aircraft manufacturer, producing the F-2 and F-15 domestically. In July 2026 it joined the Sovereign Effects Partners collaboration with Mitsubishi Electric and MBDA for the UK-Italy-Japan Global Combat Air Programme, which entered detailed design phase that month.

Hard to displace

Assessed 24 July 2026 · Evidence as of 24 July 2026

Strong structural protection; the business model survives ai pressure.

On the recordSince 24 July 2026 · Checkable from August 6, 2026 · Every call on the record Checkpoint: H3 rocket return-to-flight launch (QZS-7) after December 2025 failure

The call

MHI's business is physical, sovereign-tied, and record-backlogged; AI and rivals sit at the edges, not at the core of turbines, reactors, and fighter jets.

Mitsubishi Heavy Industries builds physical things that last decades: fighter jets, nuclear power plants, turbines, and ships for Japan and other countries. These products are hard to replace because they require specialized factories, government approvals, and decades of testing data that competitors cannot quickly copy; software and artificial intelligence cannot do what these machines do. The company is also partnering with NVIDIA to cool data centers and building the next Japanese fighter jet with the UK, so watch whether these new projects actually work and whether the company can handle US tariff increases without major damage.

Why

AI pressure: None apparent. AI shows up as a customer, not a hunter: MHI sells NVIDIA data-center cooling hardware and uses generative AI (TOMONI) for plant maintenance. Could AI do the core job? Unlikely.

Bigger players: GE Vernova and Siemens Energy. Both sell competing gas turbines worldwide, but MHI's FY2025 orders still rose 19.5% to a record ¥7.65 trillion. Could a giant copy it? No, they are blocked.

What protects it. Sole Japanese fighter-jet manufacturer status, decades of PWR nuclear operating data across 24 domestic reactors, and heavy capital plant rivals can't replicate fast.

What would change this call

H3 rocket QZS-7 launch outcome around August 6, 2026. Shows whether MHI has restored reliable launch execution after the December 2025 failure.
GCAP program funding decisions from the UK government through 2026. Shows whether political/funding instability delays MHI's fighter jet co-development role.
First disclosed customer contracts for MHI's NVIDIA-linked datacenter cooling line. Shows whether the new AI-adjacent revenue stream is gaining real commercial traction.

Key numbers

FY2025 revenue ¥4,974.1B, up 14.1% (2026-03-31)
FY2025 orders ¥7,653.6B, up 19.5% (2026-03-31)
Defense/space segment revenue ¥704.2B to ¥1,006B (2026-03-31)

Named risks

H3 rocket execution risk after December 2025 second-stage failure, return-to-flight ongoing. Severity: medium
GCAP funding instability following UK defense secretary resignation, June 2026. Severity: medium
US tariff policy impact on exports, flagged by MHI in February 2026 earnings. Severity: medium
Historical South Korea forced-labor compensation rulings remain latent legal/reputational exposure. Severity: low
