IHI is the leading jet engine company in Japan with a 60-70% market share and the primary contractor and manufacturer for the aircraft engines used by the Ministry of Defense. The Company has also developed and supplied numerous engine modules and parts for civilian aircraft. Utilizing this manufacturing experience, the IHI engine maintenance center has acquired a high reputation among Asian markets. Given the increasing demand for ecological engines, IHI is striving to research and develop next-generation engines based on advanced technologies.

Furthermore, IHI has participated in the Japanese space development effort from the beginning, developing and producing turbopumps, a key component of rocket engines, gas-jet systems, both of which are embodiments of IHI's long-fostered technologies such as cryogenic-pump and turbomachinery. These activities were greatly expanded in space when the company acquired Nissan Motor Co., Ltd's Aerospace Division, a pioneer in solid rocket development in Japan. IHI is also playing an important role in development and construction of the Exposed Facilities of Japanese Experiment Module “KIBO”, which is a part of the International Space Station program. In the field of space experiment, IHI is now a supplier of the major experimental systems required for various international cooperative experiments.
