'''H-IIA''' ('''H-2A''') is a retired Japanese [[expendable launch system]] that was developed and operated by [[Mitsubishi Heavy Industries]] (MHI) in collaboration with [[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]].

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 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 and variants ==
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 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.

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 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).

== Launch history ==
{{main|List of H-II and H3 launches}}

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 [[Information Gathering Satellite|IGS]] [[reconnaissance satellite]]s, failed. JAXA announced that launches would resume in 2005, and the first successful flight took place on 26 February 2005 with the launch of [[Multi-Functional Transport Satellite|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<ref>{{Cite web |date=24 November 2015 |title=Launch Result of Telstar 12 VANTAGE by H-IIA Launch Vehicle No. 29 |url=http://global.jaxa.jp/press/2015/11/20151124_h2af29.html |access-date=30 November 2015 |publisher=JAXA}}</ref> launched the [[Telstar 12V]] satellite, the first commercial primary payload for a Japanese launch vehicle.<ref>{{Cite web |last=William Graham |date=23 November 2015 |title=Japanese H-IIA successfully lofts Telstar 12V |url=http://www.nasaspaceflight.com/2015/11/japanese-h-iia-telstar-12v-launch/ |access-date=30 November 2015 |publisher=NASASpaceflight}}</ref>
