In 2018, Diehl Defence demonstrated a Bv 410-based IRIS-T SLS system integrated with a [[Giraffe radar|Saab Giraffe]] 1X radar during the [[ILA Berlin Air Show|ILA]]. In 2019, the [[Swedish Army]] fielded a ground launched version of the IRIS-T SLS, designated ''Luftvärnsrobotsystem 98'' (lvrbs 98), to replace the [[RBS 70]] missile system. Four missiles are carried on Eldenhet 98 (elde 98) launcher, a special version of a [[BvS 10|Bv 410 tracked]], armored vehicle. Compared to the one demonstrated on the ILA 2018, there was no radar on the Swedish Eldenhet 98.<ref>{{cite web |url=https://www.mynewsdesk.com/se/forsvarsmakten/pressreleases/nytt-robotsystem-till-foersvarsmakten-2909221 |title=Nytt robotsystem till Försvarsmakten |website=Mynewsdesk |date=22 August 2019}}</ref><ref>{{cite web|url=http://www.deagel.com/Air-Defense-Systems/IRIS-T-SLM_a002642001.aspx |title=IRIS-T SLM |publisher=Deagel |access-date=9 June 2015}}</ref> Instead, the Swedish Army used the [[Giraffe radar|Underrättelseenhet 23]] radar truck as its radar unit.<ref name="Eldenhet98Forsvarsmakten" />

In 2022, Diehl Defence showed a new air defense system called IRIS-T SLS Mk. III at the [[Eurosatory]]. It was a modified [[Mowag Eagle]] 6×6 armored vehicle integrated with IRIS-T SLS launcher, [[Hensoldt]] Spexer 2000 3D AESA, and a .50 machine gun in the [[remote controlled weapon station]]. Its [[STANAG 4569]] protection was level 1, and it could be upgraded to level 3 by adding armor kit.<ref name="2022sls" /> This vehicle had integrated the missile launcher, the radar, the sensors and the C<sup>2</sup> command system, making it able to operate independently as an air defence system.<ref>{{cite magazine |first=Maximilian |last=Eisele |date=2021 |title=A mais moderna Defesa Antiaérea Terrestre com a "Solução Germano-Brasileira" IRIS-T SLM e SLX |magazine=Tecnologia Militar |volume=43 |issue=2 |page=35 |issn=0722-2904 |language=pt}}</ref>

In February 2025, it's revealed that an Ukrainian IRIS-T SLS air defense system consisted of two Italian [[Iveco]] 4×4 trucks that integrated with SLS missile launcher. The system is also integrated with the TRML-4D radar, which guides the missiles to the target.<ref name="Ukrainian SLS">{{cite news |author=Кирило Кушніков |title=IRIS-T SLS For Ukraine Integrated On Iveco 4×4 Chassis |url=https://militarnyi.com/en/news/iris-t-sls-for-ukraine-integrated-on-iveco-4-4-chassis |date=8 February 2025 |access-date=2025-05-26 |website=militarnyi.com}}</ref>

IRIS-T SLX is an upgraded variant of IRIS-T surface-to-air missile which has the operational range of 80 km and ceiling of 30 km.<ref name="hensoldt-diehl-gbad" /> It will also use a combined radar and infrared seeker.<ref name="SLXseeker" /> On the ILA 2024, Diehl Defence displayed a missile model of the developing IRIS-T SLX, which looked quite different to both IRIS-T AAM and IRIS-T SL. This new missile can be integrated into the IRIS-T SLM launchers, which can be loaded with a mix of SL and SLX missiles as the result. Only 50 to 60 soldiers are needed for each system.<ref name="Closeto100%" /> The Diehl Defence chief programme officer Harald Buschek said this variant was capable of countering [[Standoff missile|standoff weapons]], and it was likely to be ready for operation within around 4 years. It also would retain the ability to engage cruise missiles and helicopters.<ref name="2024ILA" />

==== IRIS-T HYDEF ====
The Hypersonic Defence (HYDEF) is a program for missile defense against hypersonic threats. The consortium of this project consists of 13 companies from seven European nations. The HYDEF project is based on the successful contract signing in July 2022, dealing with a project study of an overall endo-atmospheric interceptor concept for air defence. At that time, the HYDEF project prevailed over the competitor and could win the Europe-wide tender. Hensoldt and Airbus are also involved as national partners in the HYDEF project. On 31 October 2023, SMS (Spanish Missile Systems, a collaborative proposal of {{ill|Escribano Mechanical & Engineering|es}}, [[GMV (company)|GMV]] and [[SENER]] AEROSPACIAL from Spain) and Diehl Defence signed the contract with [[Organisation for Joint Armament Cooperation|OCCAR]], marking the official start of the project.<ref>{{cite news |title=HYDEF Project reaches next milestone |date=31 October 2023 |url=https://www.diehl.com/defence/en/press-and-media/news/hydef-project-reaches-next-milestone/ |website=Diehl Defence |access-date=15 November 2023}}</ref> It has the operational range of 100 km and ceiling of 50 km.<ref name="White2024Addressing">{{cite magazine |title=Addressing the Hypersonic Threat: Challenges and Responses |last=White |first=Andrew |date=2024 |magazine=Military Technology |volume=48 |issue=2 |pages=16 |issn=0722-3226}}</ref>

On the ILA 2024, Diehl Defence revealed that they were working on a two-stage missile to defend against hypersonic weapons. It will consist of a booster as a starting engine and a warhead called "Kill vehicle" for the direct hit. This should enable it to attack targets at a distance of up to 100 km and an altitude of 50 km with a high level of agility. It should refer to IRIS-T HYDEF.<ref name="Closeto100%" />
