The new booster is set to replace the H-IIA and H-IIB launchers, which are the mainstay of Japan’s orbital rocket fleet. Mitsubishi Heavy Industries and IHI are leading the development of the new two-stage launch vehicle.
H-III is designed to launch payloads at lower costs. The basic configuration can carry 4 metric tons into sun synchronous orbit. By adding two to four strap-on boosters to the first stage, H-III will be able to lift up to 6.5 metric tons into geostationary transfer orbit.
The new booster will have a base cost of about 5 billion yen ($43.9 million). The H-IIA costs an estimated 10 billion yen ($87.8), with the more powerful H-IIB costing 10 billion yen ($131.5 million).
JAXA’s goal is for the H-III to complete flight tests and enter service in March 2021.
TOKYO (JAXA PR) — Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) successfully launched the H-IIB Launch Vehicle No. 6 (H-IIB F6) with cargo transporter to the International Space Station, the H-II Transfer Vehicle “KOUNOTORI6” (HTV6) on board at 10:26:47 p.m. on December 9, 2016 (JST) from the Tanegashima Space Center.
The launch vehicle flew as planned, and at approximately 15 minutes and 11 seconds after liftoff, the separation of HTV6 was confirmed.
At the time of the launch,the weather was fine, the wind speed was 4.3 meters/second, from the north-west, and the temperature was 15.5 degrees Celsius.
TOKYO (JAXA PR) — As a result of the successful launch of the H-IIB Launch Vehicle No. 3, the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries LTD. (MHI) have agreed to privatize the H-IIB launch service today according to the “Basic Agreement on Development and Launch Service of the H-IIB Launch Vehicle.”
With today’s agreement, JAXA will procure launch and transportation services from MHI when a payload is launched by the H-IIB Launch Vehicle. However, JAXA will continue to take responsibility of safety operations including overall safety confirmation, ground safety assurance, and flight safety and flight data acquisition in the same framework as when an H-IIA Launch Vehicle is launched.
Through the privatization, we can expect to secure Japan’s international competitiveness both for the H-IIA and H-IIB by reducing costs, improving quality and energizing activities via efficient and swift management methods of the private sector. Meanwhile, JAXA would like to engage in enhancing reliability as well as maintaining and operating Japan’s launch facilities for Japan’s flagship launch vehicle series in order to provide reliable launch means to broader demands.

On December 16, JAXA and Mitsubishi Heavy Industries Ltd. conducted a cryogenic test of the H-IIB Launch Vehicle No. 2 (H-IIB F2) at the Tanegashima Space Center. The launch vehicle and the ground system were connected for the test and all the launch operation procedures just prior to ignition were simulated in the same manner as on the launch day. As a result, no problem was found in functions and data of the launch vehicle and the ground system. We will thus move forward to be ready for launch.
The launch of the H-IIB Launch Vehicle No. 2 (H-IIB F2) with the H-II Transfer Vehicle 2 (HTV2, a cargo transporter to the International Space Station) onboard was reported to the Space Activities Commission (SAC) is as follows.
Scheduled date of launch
: January 20 (Thursday), 2011 (Japan Standard Time, JST)
: Around 3:29 p.m. (JST)*1
: January 21 (Fri.) through February 28 (Mon.), 2011 (JST)*2
: Yoshinobu Launch Complex at the Tanegashima Space Center
(*1) Time will be determined by the updated orbit of the International Space Station (ISS.) (*2) The launch day and time during the launch windows shall be decided by the international coordination for ISS operations.
The H-II Transfer Vehicle (HTV) Demonstration Flight and the H-IIB Launch Vehicle are undergoing final launch preparations at the Vehicle Assembly Building waiting for their launch on Sept. 11 (Fri.) JAXA will broadcast a live launch report through the Internet from 1:30 a.m. on Sept. 11th (Japan Standard Time)Â [12:30 p.m. ET Thursday, Sept. 10]. You can enjoy the dynamism of the launch at the Tanegashima Space Center from your home. We welcome your supportive messages to the HTV and H-IIB project teams who are working hard to be ready for the launch.
Japan’s $155 million launch, scheduled for the southern Tanegashima spaceport in the wee hours of September 11, is intended to showcase the new rocket that JAXA and Mitsubishi Heavy Industries spent the last five years building. It’s also likely to inject a new dimension into Asia’s ongoing rocket race, the latest salvo of which was South Korea’s planned satellite launch this week. Seoul’s hopes were first decried by Pyongyang, which saw its own recent rocket launch meet with U.N. sanctions. But technical glitches scrubbed the South Korean launch.
The comprehensive ground test for the H-IIB Launch Vehicle using the Ground Test Vehicle (GTV) was held at the Tanegashima Space Center on July 11.
Although the GTV was not equipped with the fairing, the flight engine and four Solid Rocket Boosters (SRB-As) were attached. During the test, the exact same procedures as the real launch procedures were followed up until the engine ignition for the final confirmation of the vehicle, ground facilities and operation procedures.
The first launch of the H-IIB is set for September 11. It will carry the HTV cargo vehicle with fresh supplies to the International Space Station.
The Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries, Ltd. would like to announce that the launch of the H-IIB Launch Vehicle Test Flight with the H-II Transfer Vehicle (HTV, a cargo transporter to the International Space Station) onboard was approved by the Space Activities Commission (SAC) as follows.

The First Captive Firing Test for the First Stage Flight Model Tank for the H-IIB Launch Vehicle
The Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries, Ltd. postponed the first captive firing test (CFT) on March 27, 2009 (all times and dates are Japan Standard Time) at the Tanegashima Space Center due to an abnormal phenomenon in the coolant supply. Abnormal phenomenon: Coolant, which is supposed to pour and sprinkle for protecting the facilities and surrounding area when the launch vehicle engine is fired, did not pour and sprinkle.
