Mitsubishi Heavy Industries
Japanese aerospace prime contractor; sole operator-of-record for JAXA's H-IIA and H3 launch vehicles since taking over commercial operations from Rocket System Corporation (RSC) in 2007. Builds engines, propulsion, and orbital infrastructure across the Japanese space program.
FINANCIAL HEALTH
SCHEDULE CREDIBILITY
How well this operator historically meets its own projected dates — launch NETs, company-announced roadmap milestones, and forward-dated facility plans. 100 = says what it does. Discount forward guidance accordingly.
| Source | Events | Late (share) | Median slip | Median slip, late only | Sub-score | On-time allowance |
|---|---|---|---|---|---|---|
| Launch NETs | 1 | 1 (100%) | 2 d | 2 d | 93.8 | 1 d |
WORST SLIPS (RECEIPTS)
| Commitment | Source | Announced | Outcome | Slip |
|---|---|---|---|---|
| H3-30 Test Flight NET changed 1x | Launch NETs | 2026-06-10 | 2026-06-12 | 2 d |
SCI = 100 × Σ(event credit) ÷ N over the trailing 36 months (2023-06-17 → 2026-06-16). Event credit = 1.0 when the commitment met its announced date (launches: net NET slip < 1 day; roadmap milestones & facility plans: within 30 days of the announced target window — month/year-precision targets count the whole period as on-time), else 30 ÷ (30 + days late beyond that allowance). Sources are pooled, so each source weighs by its event count. Sources: launch NET-change log (LL2 ingest, tracked since 2026-04-17; flown launches in coverage + not-yet-flown launches already slipped ≥1 day; cancelled launches excluded), roadmap registry milestones (company-announced targets, verified provenance only; open milestones past target count as late by days-overdue), facility_plans rows with target_date after announced_at (filing-dated rows excluded). Confidence: high ≥20 events, medium ≥8, low ≥5; no score below 5 events. 100 = says what it does.

METHODOLOGY
Launch history and subsystem outcomes aggregate from AstraVeris's launch_events table with Wilson 95% lower bounds on success rates. ARI scores come from the 11-factor composite (/finance/methodology/). Constellation counts derive from the live CelesTrak/GCAT object catalog. Gov contracts from USAspending.gov awards; private deals from deduplicated pipeline deal extraction. Absence of a row means "not tracked" — we never fabricate. See /methodology/ for the full data model and /data-licensing/ for licensing terms.
