Improved Klasma

The Improved Klasma is a Swedish naval influence mine designed for shallow and coastal water defense. It utilizes a sophisticated multi-influence sensor suite, including acoustic, magnetic, and pressure sensors, to detect and target surface vessels and submarines. The mine can be deployed from various naval platforms to establish highly effective defensive barriers in strategic littoral zones.

Developed by Bofors Underwater Systems (now Saab Dynamics) in the late 1980s, the Improved Klasma was designed to upgrade Sweden's mine warfare capabilities during the late Cold War. It entered service with the Swedish Navy in the early 1990s as a key component of their coastal defense strategy. Over the years, the system has undergone several electronic and sensor upgrades to maintain effectiveness against modern stealth submarines and countermeasure systems. It remains in active service and reserve stockpiles as a highly reliable defensive weapon.
