MHI Launch Services

MHI Launch Services, Ltd. a subsidiary of Mitsubishi Heavy Industries (MHI), is the launch provider for space crafts and performed a main role in Japanese space programs for about half century.

MHI, headquartered in Tokyo, Japan, is one of the world’s leading heavy machinery manufacturers, with consolidated sales of 3,203 billion yen (28 Billion USD) in 2007. MHI produces approximately 700 products thru various product lines and services including shipbuilding, power plants, chemical plants, environmental equipment, steel structures, industrial and general machinery, aircraft, air-conditioning systems and space rocketry.

Japan’s current launch vehicle, the H-IIA, was developed by MHI under contract from Japan Aerospace Exploration Agency (JAXA). The new H-IIB launch vehicle is being developed as a partnership between JAXA and MHI. JAXA is responsible for the basic configuration, the first-stage firing tests of the clustering engines, and the total vehicle system verification tests at the launch site. Meanwhile, MHI is responsible for the detailed design and manufacturing of the flight test vehicle and the ground verification tests. The H-IIB will be the first Japanese launch vehicle to use clustered engines.


Company History

In 2007 MHI took over H-IIA launch operations from JAXA and started its own commercial launch services. Prior to that, MHI had already been involved in 11 successful H-IIA rocket launches with JAXA. At present, the launch service uses only the H-IIA launch vehicle. Unlike the H-IIA, the H-IIB is capable of launching dual 2- to 4-tonne geostationary satellites at one time, which was a great cost saving over two separate H-IIA flights. This would help reduce the overall cost of satellite projects, which made the H-IIB a strong commercial asset.

The first H-IIA was successfully launched on August 29th 2001, followed by a string of successes. The sixth launch on November 29th in 2003, intended to launch two IGS reconnaissance satellites, failed. JAXA announced that launches would resume in 2005, and the first successful flight took place on February 26th with the launch of weather and aviation control satellite, the MTSAT-1R, built by Space Systems/Loral (SS/L) for the Japan Meteorological Agency (JMA).

The H-IIB was the first joint development project between JAXA and MHI when it was shipped to the Tanegashima Space Center in early 2009. JAXA did the research and development and was responsible for the basic configuration while MHI was entrusted with the design, development and manufacturing.

In 2010, NASA’s space shuttle was retired. MHI felt the great sense of responsibility to complete the HTV as an essential vehicle to transport materials to the International Space Station (ISS). Pairing up with JAXA was making the first launch of the H-IIB and the HTV a success. The H-IIB had increased launch capabilities, and was aderivative of the H-IIA family. H-IIB uses two LE-7A engines in its first stage, as opposed to one in H-IIA. The first H-IIB was successfully launched on September 10th, 2009.

The first launch for a mission beyond Earth orbit was on September 14th, 2007 for the SELENE moon mission. The first foreign payload on the H-IIA was the Australian FedSat-1, a 50kgs weighing Australian scientific micro satellite, in 2002. As of March 2015, 27th out of 28 launches were successful.

For the 29th flight on November 24th, 2015, an H-IIA with an upgraded second stage launched the Telesat’ Telstar-12V satellite, the first commercial primary payload for a Japanese launch vehicle. The Telstar-12V launch took place at the Tanegashima Space Center and was a key event for MHI, given that Telesat was one of the ‘Big Four’ FSS operators. MHI aims to bring the cost of its launch services down to compete with new launch vehicles such as the Falcon 9 of SpaceX and Ariane 6 of Arianespace. These plans will be accelerating around 2020 when the company hopes to bring its H3 launch vehicle to market.

Mitsubishi Heavy Industries has played an important role in the development and manufacturing of Japanese space transportation systems from early on. In 2007 MHI started providing launch services with their H-IIA launch vehicle for both commercial and government missions and in 2013, the H-IIB was entered into commercial satellite launch services.
