'''H-IIA''' ('''H-2A''') is an active [[expendable launch system]] operated by [[Mitsubishi Heavy Industries]] (MHI) for the [[JAXA|Japan Aerospace Exploration Agency]]. These liquid fuel [[rocket]]s have been used to launch [[satellite]]s into [[geostationary orbit]]; lunar orbiting spacecraft; ''[[Akatsuki (spacecraft)|Akatsuki]]'', which studied the planet Venus; and the [[Emirates Mars Mission]], which was launched to Mars in July 2020. Launches occur at the [[Tanegashima Space Center]]. The H-IIA first flew in 2001. {{As of|2024|9}}, H-IIA rockets were launched 49 times,<!-- UPDATE after each flight --> including 43 consecutive missions<!-- UPDATE after each flight --> without a failure, dating back to 29 November 2003.
'''H-IIA''' ('''H-2A''') is a retired Japanese [[expendable launch system]] that was developed and operated by [[Mitsubishi Heavy Industries]] (MHI) in collaboration with the [[Japan Aerospace Exploration Agency]] (JAXA). It was primarily used to launch [[satellite]]s into [[geostationary orbit]], interplanetary probes, and Earth observation missions. Notable payloads launched by the H-IIA include ''[[Akatsuki (spacecraft)|Akatsuki]]'', a [[Venus]] climate orbiter, and the [[Emirates Mars Mission]], which was launched toward [[Mars]] in July 2020. All launches were conducted from the [[Tanegashima Space Center]].


Production and management of the H-IIA shifted from JAXA to MHI on 1 April 2007. Flight 13, which launched the lunar orbiter [[SELENE]], was the first H-IIA launched after this privatization.<ref>{{cite web |url=http://www.satnews.com/stories2007/4356/|title=Mitsubishi and Arianespace Combine Commercial Satellite Launch Services|publisher=SatNews|url-status=dead |archive-url=https://web.archive.org/web/20120208014829/http://www.satnews.com/stories2007/4356/|archive-date=February 8, 2012}}</ref>
The H-IIA made its maiden flight on 29 August 2001 and flew a total of 50 times before its retirement on 28 June 2025. It achieved 49 successful launches, including a streak of 44 consecutive missions from 2003 to 2025. Management and production responsibility was transferred from JAXA to MHI on 1 April 2007, with Flight 13, carrying the [[SELENE]] lunar orbiter, being the first mission under private operation.<ref>{{Cite web |title=Mitsubishi and Arianespace Combine Commercial Satellite Launch Services |url=http://www.satnews.com/stories2007/4356/ |url-status=dead |archive-url=https://web.archive.org/web/20120208014829/http://www.satnews.com/stories2007/4356/ |archive-date=8 February 2012 |publisher=SatNews}}</ref>


The H-IIA is a derivative of the earlier [[H-II]] rocket, substantially redesigned to improve reliability and minimize costs. There have been four variants, with two in active service (as of 2020) for various purposes. A derivative design, the [[H-IIB]], was developed in the 2000s and made its [[maiden flight]] in 2009 before finally retired on its final launch in 2020.
The H-IIA was derived from the earlier [[H-II]] launch vehicle and featured significant design changes aimed at improving reliability and reducing cost. Several variants were developed, with the final configuration, designated H2A 202, retired in 2025. A derivative design, the [[H-IIB]], was introduced in 2009 and retired in 2020. The H-II series of launch vehicles have been succeeded by the [[H3 (rocket)|H3 rocket]], which conducted its first flight in March 2023.


== Vehicle description ==
== Vehicle description and variants ==
The base configuration, and the only remaining active configuration of an H-IIA launch vehicle, uses two [[SRB-A]] type [[solid rocket booster]]s (SRBs). The launch capability of the H-IIA launch vehicle could be enhanced by adding an additional two SRB-A boosters or up to four [[Castor (rocket stage)|Castor 4AXL]] solid strap-on boosters (SSBs).  
The H-IIA had [[multistage rocket|two-stage]] core powered by [[liquid hydrogen]] and [[liquid oxygen]], and various configurations of [[booster (rocketry)|boosters]] to provide additional thrust based on mission requirements.


The models are indicated by three or four numbers following the prefix "H2A":<ref name="leaflet">{{cite web|url=http://www.jaxa.jp/pr/brochure/pdf/01/rocket01.pdf|title=H-IIA Launch Vehicle |access-date=2007-09-15|publisher=JAXA|page=2|url-status=dead|archive-url=https://web.archive.org/web/20080228013323/http://www.jaxa.jp/pr/brochure/pdf/01/rocket01.pdf|archive-date=2008-02-28}}</ref>
The base and final active configuration, H2A 202, used two [[SRB-A]] type [[solid rocket booster]]s. Launch performance could be enhanced by adding up to two additional SRB-As for a total of four boosters, or by adding up to four [[Castor (rocket stage)|Castor 4AXL]] solid strap-on boosters (SSBs), for a total of six boosters.
* The first number in the sequence indicates the number of stages (always 2)
 
* The second number in the sequence indicates the number of [[liquid rocket booster]]s (a planned addition to the launch vehicle that was canceled, so always 0)
H-IIA configurations were designated by a three- or four-digit code following the prefix "H2A":<ref name="leaflet">{{Cite web |title=H-IIA Launch Vehicle |url=http://www.jaxa.jp/pr/brochure/pdf/01/rocket01.pdf |url-status=dead |archive-url=https://web.archive.org/web/20080228013323/http://www.jaxa.jp/pr/brochure/pdf/01/rocket01.pdf |archive-date=28 February 2008 |access-date=15 September 2007 |publisher=JAXA |page=2}}</ref>
* The third number in the sequence indicates the number of [[SRB-A]] type solid rocket boosters (2 or 4)
 
* The fourth, optional, number in the sequence indicates the number of [[Castor (rocket stage)|Castor 4AXL]] solid strap-on boosters (2 or 4)
* The first digit indicates the number of core stages (always 2).
* The second digit indicates the number of [[liquid rocket booster]]s, which were planned but never developed (always 0).
* The third digit indicates the number of SRB-A solid rocket boosters (2 or 4).
* The optional fourth digit indicates the number of Castor 4AXL strap-on boosters (2 or 4).

H-IIA (H-2A) is a retired Japanese expendable launch system that was developed and operated by Mitsubishi Heavy Industries (MHI) in collaboration with the Japan Aerospace Exploration Agency (JAXA). It was primarily used to launch satellites into geostationary orbit, interplanetary probes, and Earth observation missions. Notable payloads launched by the H-IIA include Akatsuki, a Venus climate orbiter, and the Emirates Mars Mission, which was launched toward Mars in July 2020. All launches were conducted from the Tanegashima Space Center.

The H-IIA made its maiden flight on 29 August 2001 and flew a total of 50 times before its retirement on 28 June 2025. It achieved 49 successful launches, including a streak of 44 consecutive missions from 2003 to 2025. Management and production responsibility was transferred from JAXA to MHI on 1 April 2007, with Flight 13, carrying the SELENE lunar orbiter, being the first mission under private operation.[1]

The H-IIA was derived from the earlier H-II launch vehicle and featured significant design changes aimed at improving reliability and reducing cost. Several variants were developed, with the final configuration, designated H2A 202, retired in 2025. A derivative design, the H-IIB, was introduced in 2009 and retired in 2020. The H-II series of launch vehicles have been succeeded by the H3 rocket, which conducted its first flight in March 2023.

Vehicle description and variants

The H-IIA had two-stage core powered by liquid hydrogen and liquid oxygen, and various configurations of boosters to provide additional thrust based on mission requirements.

The base and final active configuration, H2A 202, used two SRB-A type solid rocket boosters. Launch performance could be enhanced by adding up to two additional SRB-As for a total of four boosters, or by adding up to four Castor 4AXL solid strap-on boosters (SSBs), for a total of six boosters.

H-IIA configurations were designated by a three- or four-digit code following the prefix "H2A":[2]

  • The first digit indicates the number of core stages (always 2).
  • The second digit indicates the number of liquid rocket boosters, which were planned but never developed (always 0).
  • The third digit indicates the number of SRB-A solid rocket boosters (2 or 4).
  • The optional fourth digit indicates the number of Castor 4AXL strap-on boosters (2 or 4).

Launch history

Script error: No such module "Labelled list hatnote".

The first H-IIA was successfully launched on 29 August 2001, followed by a string of successes.

The sixth launch on 29 November 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 26 February 2005 with the launch of MTSAT-1R.

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

A rocket with increased launch capabilities, H-IIB, is a derivative 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 10 September 2009.

For the 29th flight on 24 November 2015, an H-IIA with an upgraded second stage[6] launched the Telstar 12V satellite, the first commercial primary payload for a Japanese launch vehicle.[7] Template:Sticky header

A hot gas leak from SRB-A motor destroyed its separation system and the booster did not separate as planned. The weight of the spent motor prevented the vehicle from achieving its planned speed and height and it was destroyed via a ground command about 10 minutes into the flight.[8]
