Aero Engine, Space & Defense

Pioneering the future in the fields of aviation, space, & defense.

Our projects include work in the fields of aircraft engines, rocket systems, outer space utilization, and defense equipment systems. As a leading aircraft engine company, we help support the air transport industry, while in the space field we work on developing and producing turbopumps found at the heart of rocket engines, and have worked on next generation rockets such as Epsilon. With demand for aircraft expected to double in the next 20 years, we are working with new materials to develop lighter, quieter engines in order to reduce environmental impact.

Main business

We handle approximately 70% of jet engine production in Japan.

Aircraft Engines

IHI is Japan’s leading maker of jet engines, with a market share of around 70%. We are the primary contractor and manufacturer for aircraft engines used by the Ministry of Defense, covering all fighter aircraft models. We collaborate in international projects to develop and supply engine modules and components for civilian aircraft, and are renowned as Asia’s core engine maintenance provider. We conduct research and development into advanced, eco-friendly engines.

Applying our cutting edge technologies to activities in other fields.

Rocket Systems & Space Exploration

IHI has participated in Japan’s space development effort from the outset. We have developed and manufactured the turbopumps and gas-jet systems that are crucial to successful rocket launches.
Our involvement in Japan’s space program expanded significantly in 2000, when we absorbed the Aerospace Division of Nissan Motor, a leader in solid-fuel rocket technology. We play an important role in developing and constructing the Exposed Facilities of the KIBO Japanese Experiment Module, which is a part of the International Space Station program. We support experiments in space by supplying experimental systems needed for cooperative international projects.

Helping airports return to operation quickly following disasters.

Traffic Control

Air traffic control systems are essential to the safe flight of aircraft. These systems take care of the consolidation and total control of wireless and fixed-line communication for air traffic control and allow airport control duties to be performed from the control tower. Furthermore, the emergency airport traffic control tower system which operates as an alternative system when the main system is inoperable for unforeseen reasons, is portable, meaning it can be transported to other airports. It is configured of 3 systems, a control tower, control and power supply. An emergency system was transported from Haneda Airport to Sendai Airport after the Great East Japan Earthquake struck in March of 2011, and it contributed to the swift recovery of the airport’s operations.
