The roots of the [[ASRAAM]] date back to 1968 when development began on the [[Hawker Siddeley]] [[SRAAM]] ("Taildog"). This project ended in 1974 with no production orders. This work was dusted off for the UK–German effort, with the Germans providing a new seeker, and the UK providing most of the remaining components.
 
After [[German reunification]] in 1990, Germany found itself with large stockpiles of the Soviet [[Vympel R-73]] missiles (NATO reporting name: ''AA-11 Archer'') carried by the [[MiG-29 Fulcrum]] and concluded that the AA-11's capabilities had been noticeably underestimated.<ref>{{cite web|last=Menon|first=KB|title=Evolution of the Air-To-Air Missiles: Options for the IAF|date=17 July 2012 |url=http://www.indiandefencereview.com/news/evolution-of-the-air-to-air-missiles-options-for-the-iaf/|access-date=11 June 2014}}</ref> InIntegrating particularwith a helmet-mounted sight, it was found to be both far more manoeuvrable and capable in terms of seeker acquisition and tracking[[dogfight]] than the latest [[AIM-9 Sidewinder]].<ref>{{citeCite magazine |first=Tim |last=Robinson |date=July 2002 web|title=LockingThe Market for 4th Generation Dogfight Missiles range|urlmagazine=http://www.cassindia.com/inner_page.php?idMilitary Technology |volume=26&&task |issue=research7 |access-datepages=1151 June|quote= 2014}}</ref>{{betterWhat sourcealso was critical with R-73 was its integration with a helmet-mounted sight, allowing impressive off-boresight shots. needed|dateissn=October 20220722-3226}}</ref> In 1990, Germany withdrew from the ASRAAM project, while the UK resolved to find another seeker and develop ASRAAM according to the original range requirement.<ref>{{cite book |title=Arms and the State: Patterns of Military Production and Trade |publisher=[[Cambridge University Press]] |date=25 August 1995 |page=253 |isbn=0521558662 |no-pp=true}}</ref> This ultimately led to the ASRAAM gaining a significantly more capable 128×128 focal array seeker with IRCCM (infrared ''counter'' countermeasures) capability, similar performance and notably half the unit cost of the IRIS-T due to the development work that had already been completed on the missile body.{{Citation needed|date=April 2023}}
 
In 1987, after years of silence on the program, the US proposed a requirement that the weapon must use Sidewinder rails rather than the universal aircraft rail adaptor named the "missile support unit" that had been developed. This delayed the project by one year as the British, German and Norwegian proposals were redesigned. Fearing erosion of its industrial base, the US proposed it would choose the latest version of its existing Sidewinder design with increased manoeuvrability and IRCCM unless the European partners increased the US industrial workshare,<ref>{{cite web | url=https://www.thinkdefence.co.uk/2022/11/advanced-short-range-air-to-air-missile-asraam/ | title=Advanced Short Range Air to Air Missile (ASRAAM) - Think Defence | date=5 November 2022 }}</ref> designated [[AIM-9X Sidewinder#AIM-9X|AIM-9X]].<ref>{{cite web|last=Tirpak|first=John|title=The Evolution of the Force|url=http://www.airforcemag.com/MagazineArchive/Pages/1996/July%201996/0796force.aspx|access-date=11 June 2014}}</ref> However, the Sidewinder upgrade proposal failed to interest NATO buyers and, in 1992, the missile development programme ultimately separated with the UK the ASRAAM, France the [[MBDA MICA]], US the AIM-9X and Germany electing to restart development on what became the IRIS-T.

==Missile characteristics==
In comparison to the AIM-9M Sidewinder, the IRIS-T has higher [[Electronic countermeasure|ECM]] resistance and flare suppression.<ref>{{cite web|title= IRIS-T Guided Missile Family, Germany | publisher = Diehl |url= http://www.diehl.com/en/diehl-defence/products/guided-missiles/iris-t-guided-missile-family/iris-t.html|access-date=11 June 2014 |archive-url=https://web.archive.org/web/20180603073851/http://www.diehl.com/en/diehl-defence/products/guided-missiles/iris-t-guided-missile-family/iris-t.html |archive-date=2018-06-03 |url-status= dead}}</ref> Improvements in target discrimination allow for five to eight times longer head-on firing range than the AIM-9M. It can engage targets behind the launching aircraft, made possible by extreme close-in agility, allowing turns of 60 ''g'' at a rate of 60°/s via thrust vectoring and [[Lock-on after launch|LOAL]] capability.<ref name=diehl /><ref>{{cite web|title= IRIS-T Air-to-Air Guided Missile, Germany | work = Air force technology |url= http://www.airforce-technology.com/projects/iris-t-air-air-guided-missile-germany/|access-date=11 June 2014}}</ref><ref name=diehl />
 
The IRIS-T is able to intercept fast-moving and miniature targets, such as air-to-air/surface-to-air missiles and air-to-surface/surface-to-surface missiles and rockets, UAV/drones, and cruise missiles. To improve the probability of a direct hit, the missile is equipped with an active radar proximity fuze.<ref name= diehl-brochure-2018>{{cite web|url= https://www.diehl.com/cms/files/Diehl_Defence_Brosch%C3%BCre2018_en.pdf|title= Living in a safe environment: Technology for peace and freedom| publisher =[[Diehl Defence]] |accessdate=6 July 2022}}</ref>
 
The IRIS-T has the unique ability, in comparison to other similar missiles such as the AIM-9X, to target and shoot down other air-to-air and surface-to-air missiles, thus offering a 360° defence capability.<ref name= diehl /><ref>{{cite web|title= IRIS-T European Short Range Air-to-air Missile | publisher = Diehl |url= http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/IRIS-T_e_Eurofighter.pdf|access-date= 10 March 2018|archive-url= https://web.archive.org/web/20130612054850/http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/IRIS-T_e_Eurofighter.pdf |archive-date= 12 June 2013|url-status= dead}}</ref><ref name= diehl /> Surface launched variants of the IRIS-T, the IRIS-T SLS and IRIS-T SLM, have enhanced capabilities to destroy aircraft, helicopters, cruise missiles, air-to-surface missiles, anti-ship missiles, anti-radar rockets and large-calibre rockets. They have a high probability of a killing shot against UAVs and other small manoeuvring threats at very-short and medium-range distances.<ref>{{cite web |title= IRIS-T SL Surface-to-Air Guided Missile | work = Air force technology |url= http://www.airforce-technology.com/projects/iris-t-sl-surface-to-air-guided-missile/ |archive-url= https://web.archive.org/web/20141031175346/http://www.airforce-technology.com/projects/iris-t-sl-surface-to-air-guided-missile |archive-date=2014-10-31 |url-status=dead}}</ref>
 
The [[Royal Norwegian Air Force]] (RNoAF) has tested a new air-to-surface capability developed by Diehl BGT Defence for the IRIS-T. A proof of concept test firing to acquire, track, and engage a target representing a small fast attack boat was conducted in Norway in September 2016, where the IRIS-T missile was launched from an RNoAF F-16AM multirole aircraft. For the air-to-surface role, the missile retains the same standard IRIS-T AAM hardware configuration, including the HE warhead and IIR guidance package, with only an updated software insertion required to deliver the additional ground attack capability.<ref>{{cite web|title= Diehl develops air-to-surface capability for IRIS-T AAM |url= http://www.janes.com/article/66304/diehl-develops-air-to-surface-capability-for-iris-t-aam | work = Jane’s |archive-url= https://web.archive.org/web/20161216141501/http://www.janes.com/article/66304/diehl-develops-air-to-surface-capability-for-iris-t-aam |archive-date=2016-12-16 |url-status= dead}}</ref> This basic air-to-ground capability provides the ability to acquire, track and engage individual ground targets like boats, ships, small buildings and vehicles.<ref>{{cite web| publisher = Diehl | type = Press release | title = Royal Norwegian Air Force tested IRIS-T in air-to-ground mission|url= http://www.diehl.com/en/nc/diehl-defence/press/royal-norwegian-air-force-tested-iris-t-in-air-to-ground-mission.html |archive-url= https://web.archive.org/web/20161216115459/http://www.diehl.com/en/nc/diehl-defence/press/royal-norwegian-air-force-tested-iris-t-in-air-to-ground-mission.html |archive-date=2016-12-16 |url-status= dead}}</ref>
