arsenal.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls muted src=\"https:\/\/deaidua.org\/news\/wp-content\/uploads\/2025\/11\/Air-Command-West-several-IRIS-T-SLM-launches.mp4\"><\/video><figcaption class=\"wp-element-caption\">IRIS-T SLM intercepts various Russian targets in Ukraine | Video: Air Command West<\/figcaption><\/figure>\n\n\n\n<p>This makes it all the more interesting that Ukraine, in agreement with the German Ministry of Defence, has apparently decided to upgrade the 18 fire units already delivered and promised to Ukraine, equipping each with two additional launchers.<\/p>\n\n\n\n<p>A contract worth around \u20ac182 million between Ukraine and the manufacturer Diehl Defence, with Germany providing the funding, was signed on the sidelines of the German-Ukrainian government consultations held this week.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Possible reasons behind the decision<\/h2>\n\n\n\n<p>Although no further details regarding the possible reasons for this decision have been officially disclosed, they are nevertheless obvious.<\/p>\n\n\n\n<p>Unsurprisingly, Ukraine appears to have an immediate need for additional state-of-the-art air defence systems beyond the deliveries already planned, whilst the German Ministry of Defence, however, has only a very limited budget at its disposal.<\/p>\n\n\n\n<p>Until now, this has only been a problem to a limited extent, as the manufacturer, Diehl Defence, has significantly increased its production capacity over the years and the Ukrainian Armed Forces have regularly been given priority in the delivery of newly manufactured ammunition and fire units.<\/p>\n\n\n\n<p>Germany, Estonia and Egypt had in the past for example temporarily foregone the delivery of equipment to their own armed forces so that it could be forwarded to Ukraine.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"572\" src=\"https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-1024x572.webp\" alt=\"Logistics Specialists of the Air Command West are working on a IRIS-T SLM launcher\" class=\"wp-image-4805\" srcset=\"https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-1024x572.webp 1024w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-300x168.webp 300w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-768x429.webp 768w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-512x286.webp 512w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM-920x514.webp 920w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2024\/12\/Logistics-Specialists-Air-Command-West-IRIS-T-SLM.webp 1273w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">An IRIS-T SLM launcher with Egyptian camouflage in service with Ukraine alongside a support vehicle | Image: Air Command West <\/figcaption><\/figure>\n\n\n\n<p>Those deliveries are now being resumed, whilst others are proceeding as planned. Apart from Ukraine, which, according to my information, is set to receive another three new fire units this year, Denmark, Estonia, Latvia and Germany are all expecting new material.<\/p>\n\n\n\n<p>In other words: at least this year, there are unlikely to be any additional production slots available for Ukraine. Any additional fire units ordered would probably not be delivered until the end of 2028.<\/p>\n\n\n\n<p>At the same time, the German Ministry of Defence has only a very limited budget at its disposal. Although, at \u20ac11.5 billion, more funds have never been allocated for military assistance in a single year, additional projects \u2013 including the PURL programme \u2013 are now also requiring funding.<\/p>\n\n\n\n<p>It therefore seems that they have settled for the \u201cnext best\u201d option: reinforcing the fire units that have already been delivered and pledged.<\/p>\n\n\n\n<p>As various support vehicles, TRML-4D radar units, TOCs and other components do not need to be manufactured and therefore do not incur any costs, the price is relatively very low and is therefore affordable for the German Ministry of Defence.<\/p>\n\n\n\n<p>At the same time, Ukraine\u2019s air defence capabilities are being significantly bolstered with 36 additional launchers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The next steps in the process<\/h2>\n\n\n\n<p>It is also unclear exactly how the reinforcement is to be carried out. However, I cannot see why it should not be carried out in the same way as the previous reinforcement of the IRIS-T SLM fire units.<\/p>\n\n\n\n<p>After all, the German government has already funded the delivery of two additional IRIS-T SLS launchers in recent years, which are delivered alongside each newly manufactured IRIS-T SLM fire unit for Ukraine and have also been retrofitted into fire units delivered before.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"960\" src=\"https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited.webp\" alt=\"IRIS-T SLS launcher\" class=\"wp-image-8681\" srcset=\"https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited.webp 960w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited-300x300.webp 300w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited-150x150.webp 150w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited-768x768.webp 768w, https:\/\/deaidua.org\/news\/wp-content\/uploads\/2026\/04\/IRIS-T-SLS-Air-Command-West-edited-860x860.webp 860w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\" \/><figcaption class=\"wp-element-caption\">An IRIS-T SLS launcher in Ukrainian service | Image: 11th Anti-Aircraft Missile Brigade<\/figcaption><\/figure>\n\n\n\n<p>It can therefore be assumed that the German Ministry of Defence will follow this blueprint and that the nine fire units pledged will now be delivered to Ukraine, each equipped with one additional IRIS-T SLM launcher (medium range) and one additional IRIS-T SLS launcher (short range), whilst, over the coming months and years, the other nine fire units already in service with the Ukrainian Armed Forces will be retrofitted.<\/p>\n\n\n\n<p>Put simply, this means that the Ukrainian IRIS-T SLM fire units will soon have more than twice the firepower of the units originally deployed to defend Ukraine in 2022 and 2023.<\/p>\n\n\n\n<p>The number of launchers in a fire unit has increased from the original three (3 SLMs) to five (3 SLMs and 2 SLSs). Soon there will be seven launchers (4 SLMs and 3 SLSs), which is likely to be the maximum, as a single fire unit can accommodate a maximum of eight launchers.<\/p>\n\n\n\n<p>The planned upgrade also gives cause for hope regarding the supply of missiles.<\/p>\n\n\n\n<p>After all, there is no point in integrating additional launchers into a fire unit if one cannot meet the resulting demand for additional missiles.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-default\"\/>\n\n\n\n<p id=\"b5de\">If you liked this post, consider following me on&nbsp;<a href=\"https:\/\/twitter.com\/deaidua\" target=\"_blank\" rel=\"noreferrer noopener\">X<\/a>,&nbsp;<a href=\"https:\/\/bsky.app\/profile\/deaidua.org\" target=\"_blank\" rel=\"noreferrer noopener\">Bluesky<\/a>,&nbsp;<a href=\"https:\/\/t.me\/deaiduaTG\">Telegram<\/a>&nbsp;or&nbsp;<a href=\"https:\/\/www.youtube.com\/@deaidua\" target=\"_blank\" rel=\"noreferrer noopener\">YouTube<\/a>.
