CASE STUDY

Swedish Navy chooses OneCIS®

OneCIS® equips the Swedish Navy for NATO-ready maritime IT operations

This OneCIS® case study shows how MilDef supports the Swedish Navy with a NATO-ready tactical IT platform that enables secure communications, interoperability and rapid deployment across maritime operations. As Sweden integrates into NATO, mission success increasingly depends on resilient digital infrastructure that can connect ships, command posts and allied forces.

1. The challenge: NATO-ready maritime interoperability

As Sweden integrates into NATO, its defense forces face the challenge of achieving full interoperability with allied nations. Maritime operations demand secure, real-time communication between ships, command posts, and joint task forces, while long deployment cycles and fragmented systems create bottlenecks that limit readiness and increase cyber and coordination risks.

2. The Solution: OneCIS® tactical IT platform

To address this need, the Swedish Defence Materiel Administration (FMV) selected MilDef’s tactical IT platform, OneCIS – a NATO FMN-compliant solution designed for rapid deployment and allied interoperability. 

Through an agreement valued at 81 MSEK (with potential to reach 127 MSEK), OneCIS will be deployed across the Swedish Navy’s ships and command posts, providing a unified and secure foundation for communication in NATO’s connected environment. Combining MilDef’s hardware, software, and integration expertise, the platform delivers end-to-end functionality and has already proven its reliability and scalability in other Nordic defense environments. 

3. Operational value for the Swedish Navy

With its modular, plug-and-play design, OneCIS® integrates efficiently into existing naval systems and remains adaptable to evolving operational requirements. 

Combining MilDef’s hardware, software, and integration expertise, the platform delivers end-to-end functionality and has already proven its reliability and scalability in other Nordic defense environments.
