About IHI Aerospace Co., LTD.

Written by GovTribe AI ·

IHI Aerospace Co., LTD., a Japanese aerospace manufacturer and subsidiary of Ishikawajima-Harima Heavy Industries Co., Ltd., operates exclusively as a subcontractor to the Department of the Navy and National Aeronautics and Space Administration, delivering aircraft engine components and space vehicle parts and materials. The vendor holds no prime contracts and generates federal revenue entirely through subcontracts, with 96% of its 45 recent awards routed through RTX Corporation as the prime contractor.

IHI Aerospace is headquartered in Tomioka, Gunma, Japan, and operates as a for-profit manufacturer of goods classified primarily under NAICS 488390 (Other Guided Missile and Space Vehicle Parts Manufacturing) and related aerospace supply codes. The vendor holds no SBA certifications and does not compete under set-aside authority — all federal work flows through large-prime teaming relationships, predominantly with RTX.

Customer concentration is severe and defense-focused. The Department of the Navy Naval Air Systems Command accounts for 40 of 45 awards (89% of recent volume), with the balance split between NASA Johnson Space Center (3 awards) and NASA Ames Research Center (2 awards, $4.5 million combined potential value). The Navy's portfolio centers on aircraft engine and engine parts manufacturing — a dominant NAICS category representing 40 of the vendor's recent awards. A single sub-award appearing in the source data as an equitable adjustment in December 2024 and a May 2024 modification for long-lead materials on Commercial Resupply Services CRS2 imply parallel NASA human spaceflight engagement, though award descriptions for most Navy sub-tasks reference internal government tracking numbers (FY21 PBL2 codes) rather than public scope narratives.

Activity has accelerated sharply. The vendor recorded one award in 2015 and one in 2016, then no visible awards until 2024. Since 2024, IHI Aerospace has logged 43 sub-awards in two years, with 30 in 2025 alone and 11 already in 2026 (as of mid-February). Combined obligated dollars ($13.6 million) exceed combined potential value ($4.5 million) by 304%, indicating that Navy task orders are regularly funded above ceiling and the source's potential-value figures understate actual program magnitude or revenue realization.

RTX Corporation is the sole named prime across all recent sub-work. The vendor's integration into RTX's FY21 Performance-Based Logistics (PBL) architecture — evident from the repetitive FY21 PBL2 tracking codes across Navy awards — positions IHI Aerospace as a committed long-tail supplier for Pratt & Whitney or Collins Aerospace engine and propulsion systems under Navy maintenance and readiness contracts. The vendor's Federal Acquisition Regulation foreign-vendor status (noted in the December 2024 equitable adjustment record) is standard for international aerospace component suppliers to RTX on defense contracts; no explicit restrictions on foreign participation appear in the source data. Two small prime awards in 2024 and a separate NASA ISS Commercial Resupply Services engineering sub-award in September 2025 suggest minor direct engagement outside the RTX channel, but the footprint remains overwhelmingly RTX Navy subcontract work.
