According to official information, the upgrades incorporate technologies equivalent to those installed on the new Blekinge-class submarines, significantly enhancing the Swedish fleet’s combat capabilities, sensor suite, and operational integration. The program was carried out by Saab, which was responsible for the development and implementation of the modernized systems.

The Swedish Navy emphasized that its submarines represent a central element of deterrence and the protection of maritime routes in the Baltic Sea region. In the current security environment, these capabilities also contribute directly to NATO’s collective defense efforts, strengthening allied surveillance and readiness in Northern Europe.
With the modernization of HMS Halland, Sweden consolidates interoperability between existing and future platforms, ensuring that its submarine fleet maintains high levels of operational effectiveness over the next decade.
