The '''IRIS-T (infrared imaging system tail/thrust vector-controlled)''' is a  short range [[infrared homing]] [[air-to-air missile|air-to-air]] missile. It is also called '''AIM-2000'''.<ref>{{Cite web |title=Luft-Luft-Rakete IRIS-T AIM-2000 |url=https://www.bundeswehr.de/de/ausruestung-technik-bundeswehr/ausruestung-bewaffnung/iris-t-aim-2000 |access-date=2023-04-06 |website=www.bundeswehr.de |language=de}}</ref><ref>{{Cite web |title=AIM-2000 (IRIS-T) Infrared Imaging Seeker - Tail |url=https://www.haf.gr/en/equipment/aim-2000-iris-t-infrared-imaging-seeker-tail/ |access-date=2023-04-06 |website=Hellenic Air Force |language=el}}</ref><ref name="IRIS-T SAAB">{{cite web|url=https://www.saab.com/products/iris-t|title=IRIS-T|website=SAAB|access-date=3 July 2025|archive-date=27 May 2025 |archive-url=https://web.archive.org/web/20250527182403/https://www.saab.com/products/iris-t |url-status=live}}</ref> The missile also has other variants, including the surface-to-air-launched [[IRIS-T SL|IRIS-T SLS and IRIS-T SLM]] and their derivatives.

The missile was developed in the late 1990s–early 2000s by a German-led program to produce a short to medium range infrared homing air-to-air missile to replace the [[AIM-9 Sidewinder]] in use by some [[NATO]] member countries at the time. A goal of the program was for any aircraft capable of firing the Sidewinder to also be capable of launching the IRIS-T.<ref>{{cite web |url=http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/2009_Flyer_IRIS-T_EFA_0509.pdf |title=IRIS-T European Short Range Air-to-Air Missile |archive-url=https://web.archive.org/web/20121119044426/http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/2009_Flyer_IRIS-T_EFA_0509.pdf |archive-date=2012-11-19 |url-status=dead}}</ref> The air-to-air variant was fielded in 2005.

==History==

=== Background ===
[[File:IRIS-T air-to-air-missile.jpg|thumb|right|An IRIS-T air-to-air missile of the [[German Air Force]].]]
In August 1980, the USA, the UK, Germany and France signed a [[Memorandum of understanding]] which aimed to develop two types of AAMs to replace existing ones. The USA developed the Advanced Medium-Range Air-to-Air Missile (AMRAAM) to replace the [[AIM-7 Sparrow]], while the Europe team developed the Advanced Short-Range Air-to-Air Missile (ASRAAM) to replace the [[AIM-9 Sidewinder]]. This work was dusted off for the UK–German effort,<ref>{{Cite book |first1=Chris |last1=Gibson |first2=Tony |last2=Buttler |title=British Secret Projects: Hypersonics, Ramjets and Missiles |url=https://archive.org/details/britishsecretpro0000gibs |publisher=Midland Publishing |page=50 |date=2007 |isbn=9781857802580}}</ref> with the Germans providing a new seeker, and the UK providing most of the remaining components.

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.

After [[German reunification]] in 1990, Germany found itself with large stockpiles of the Soviet [[Vympel R-73]] air-to-air missiles (NATO reporting name: ''AA-11 Archer'') carried by the [[MiG-29 Fulcrum]] and concluded that its 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> It was one of the earliest 4th generation WVRAAM and more capable in dogfight than the former 3rd generation ones.<ref name="airpower" /><ref>{{Cite magazine |first=Tim |last=Robinson |date=July 2002 |title=The Market for 4th Generation Dogfight Missiles |magazine=Military Technology |volume=26 |issue=7 |page=51 |quote=The revolution in WVR technology came from Russia, back when it was the Soviet Union, with a missile that was effectively a generation ahead of Western designs.

===Development===
In 1995, Germany announced the start of the IRIS-T development, in collaboration with Greece, Italy, Norway, Sweden and Canada. In 1997, Germany had invested more than 500 million [[Deutsche Mark|DM]] in this project and held a 46% share. In addition, Italy accounted for 20%, Sweden 18%, Greece 8%, Canada 4% and Norway 3%.<ref>{{cite web |url=http://www.flightglobal.com/pdfarchive/view/1997/1997%20-%203230.html |periodical=Flightglobal |title=Germany clears IRIS-T missile development |date=2 December 1997 |access-date=23 July 2014 |archive-date=2016-08-07 |archive-url=https://web.archive.org/web/20160807154412/https://www.flightglobal.com/pdfarchive/view/1997/1997%20-%203230.html |url-status=dead}}</ref> Canada later dropped out, while Spain joined as a procurement partner in 2003.<ref>{{cite web |title=IRIS-T – the world's highest-performance, short-range, air-to-air guided missile |url=http://www.diehl.com/en/nc/diehl-group/press/iris-t-the-worlds-highest-performance-short-range-air-to-air-guided-missile/190.html |archive-url=https://web.archive.org/web/20160306174050/http://www.diehl.com/en/nc/diehl-group/press/iris-t-the-worlds-highest-performance-short-range-air-to-air-guided-missile/190.html |archive-date=2016-03-06 |url-status=dead}}</ref> The [[German Air Force]] took first delivery of the missile in December 2005.<ref>{{cite web |url=http://www.thefreelibrary.com/Germany+tees-off+with+Iris.-a0143304030 |title=Germany tees-off with Iris. |archive-url=https://web.archive.org/web/20170910172546/https://www.thefreelibrary.com/Germany+tees-off+with+Iris.-a0143304030 |archive-date=2017-09-10 |access-date=11 June 2014 |url-status=live}}</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>

==== IRIS-T FCAAM air-to-air missile ====
[[File:ILA 2024, Schoenefeld (ILA44513).jpg|thumb|FCAAM]]
Diehl mentioned in 2022 that it was working on a 6th generation of short-range air-to-air missiles, and it is known as the ''"Future Combat Air-to-Air Missile"''. This missile is being designed to become one of the weapons of the European [[Future Combat Air System]].<ref>{{Cite web |last=Valpolini |first=Paolo |date=2022-07-27 |title=IRIS-T FCAAM: the future SRAAM 6th generation missile by Diehl Defence |url=https://www.edrmagazine.eu/iris-t-fcaam-the-future-sraam-6th-generation-missile-by-diehl-defence |access-date=2024-04-25 |website=EDR Magazine |language=en-GB}}</ref> Some new features of IRIS-T FCAAM might include a stealthy non-cylindrical cross-section, multiple-spectrum IR sensor, advanced data processing, a two-way datalink, and a dual pulse/multi-pulse rocket motor.<ref>{{cite magazine |first=Anil |last=Raj |date=2023 |title=Present and future air-to-air missiles |magazine=Military Technology |volume=47 |issue=1 |page=22 |issn=0722-3226}}</ref>

==== IRIS-T air-to-surface missile ====
For the air-to-surface role, the only difference from air-to-air version is an updated software insertion required to deliver the additional ground attack capability. Tested by the [[Royal Norwegian Air Force]].<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 |url-status=dead |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}}</ref>

==== IDAS (submarine-launched variant) ====
{{Main|IDAS (missile)}}

The IDAS (Interactive Defence and Attack System for Submarines) variant is a submarine-launched version of the missile, and is also being developed for the new [[Type 212A submarine]] of the [[German Navy]]. IDAS is supposed to engage air threats, small or medium surface vessels or near land targets.<ref>{{Cite web |title=null |url=https://www.thyssenkrupp-marinesystems.com/en/products-services/innovations/missile-system-idas |access-date=2024-04-25 |website=www.thyssenkrupp-marinesystems.com |language=en}}</ref>

==== LFK NG ====
{{main|LFK NG}}
LFK NG was a surface-to-air variant that was developed by the Diehl BGT Defence and MBDA/LFK for the Germany air defence plan called SysFla ({{langx|de|System Flugabwehr}}). Its weight is 28&nbsp;kg, which is just one third of the original IRIS-T AAM. It would be equipped on the Army's [[Wiesel 1#Wiesel 2|Ozelot]] air defence system and [[Eurocopter Tiger]]. It has the operational range of 10&nbsp;km.<ref>{{Cite web |url=http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/LFK_NG_Produktflyer.pdf |periodical=Diehl |title=LFK NG |date=8 August 2014 |access-date=8 August 2014 |archive-url=https://web.archive.org/web/20150923214717/http://www.diehl.com/fileadmin/diehl-defence/user_upload/flyer/LFK_NG_Produktflyer.pdf |archive-date=2015-09-23 |language=de |url-status=dead}}</ref> In 2012, the German Army air defence units {{ill|Heeresflugabwehrtruppe|de}} was disbanded.<ref>{{cite web |author=René Hinz |date=30 April 2024 |title=Heeresflugabwehrtruppe wird neu aufgestellt |url=https://www.bundeswehr.de/de/organisation/heer/aktuelles/heeresflugabwehrtruppe-wird-neu-aufgestellt-5777698 |access-date=3 May 2024 |website=www.bundeswehr.de |location=Strausberg |language=de}}</ref> There's no further news about this variant afterward.
