Saab has presented its SLIM (Saab Lightweight Integrated Mast) system to the Indian Navy, positioning it as a cutting-edge solution for integrated sensor architecture, reduced radar visibility, and efficient deck design. The proposal supports India’s transition toward network-centric naval operations where information dominance is as important as kinetic capability.
SLIM replaces traditional mast configurations by combining radars, antennas, and sensors into a single composite structure. Delivered as a pre-integrated module, it ensures synchronized sensor performance while simplifying shipbuilding and reducing integration complexity.
The system draws from Saab’s expertise in the Visby-class corvette program, leveraging advanced composite materials to reduce weight and enhance ship stability. This lightweight design contributes to improved overall performance, especially in high-demand operational scenarios.
Beyond structural benefits, SLIM’s design significantly reduces radar cross-section by limiting reflective surfaces and enabling cleaner geometries, enhancing survivability in contested maritime environments.
Saab’s comprehensive integration approach is a key differentiator, covering sensor functionality, electromagnetic compatibility, and structural precision. This turnkey solution ensures that radar, electronic warfare, and communication systems operate harmoniously without interference.
The mast’s modular and scalable architecture allows it to be customized for a wide range of vessels, from smaller corvettes to larger surface combatants. This flexibility makes it relevant for both new Indian Navy platforms and modernization programs.
SLIM is already deployed on Finland’s Pohjanmaa-class corvette and has enhanced Sweden’s Gävle-class corvette, demonstrating its effectiveness in both new builds and upgrades.
For India, adopting SLIM could significantly improve fleet-wide sensor integration, stealth capability, and operational efficiency. As naval warfare evolves toward sensor dominance, the mast is no longer just a structural feature but a critical component of combat capability.
