Frost Unmanned AB is a Swedish defence technology company founded in 2018, specialising in the design and manufacture of unmanned aerial vehicles (UAVs) and unmanned surface vessels (USVs) for military, government, and maritime security missions. Its flagship products include the Tracer-160, a jet-powered, high-speed fixed-wing UAV engineered for ISR and strike missions, and the Arrow-600, a capable unmanned surface vessel purpose-built for maritime and coastal operations. All platforms are designed and manufactured end-to-end in Sweden, emphasising sovereignty, resilience, and modularity for NATO-aligned partners.

The company integrates autonomy and multi-domain networking into its systems to shorten the kill chain and enhance situational awareness across air, sea, and space-integrated operations. In January 2025, Frost Unmanned absorbed Atgeir Autonomous Systems AB, strengthening its USV capabilities. Its solutions are aimed at ISR, logistics, and combat operations, with Ukraine as an active target market and European defence forces as the primary customer base.

Frost Unmanned participates actively in the European defence ecosystem, engaging with the Swedish Armed Forces, FMV (Försvarets materielverk), and international partners such as France's Alta Ares and Naval Group. The company has demonstrated the Arrow-600 in live trials in Askeröfjorden and is a member of SOFF (Sweden's security and defence industry association). No external funding rounds have been publicly disclosed.
