The undersea domain is rapidly becoming the decisive battleground for modern naval forces. Emerging sensors, autonomous underwater platforms and increasingly sophisticated anti-submarine threats demand that submarines be equipped with continuous, low-latency, and secure connectivity, as well as automated data-link capabilities that turn raw sensor feeds into actionable intelligence in real time.
The Rohde & Schwarz team is available to discuss its unique portfolio with integrator and end-users at the Underwater Defence Technology (UDT) Conference, April 14 - 16, 2026 in London.
The event’s 2026 theme, “Prepare Today for the Maritime Threats of Tomorrow,” provides an ideal platform to demonstrate how secure, elective automated and interoperable subsea communications is contributing to modern naval operations. Attendees will be able to see demonstrations of the company’s end-to-end system architecture, from wave-generation to AI-driven data orchestration, and will learn how the technology can be adapted to a wide range of platforms, from legacy diesel electric submarines to next-generation air independent propulsion (AIP) vessels.
Prepare Today for the Maritime Threats of Tomorrow
Traditional submarine communications have long been limited by narrow bandwidth, high latency and vulnerability to hostile environments. Rohde & Schwarz’ new waveform family, built on a flexible, software-defined core, provides secure, high-throughput links that remain operational under extreme conditions providing low probability of detection and low probability of interception. The technology delivers interoperable connectivity not only between fleet assets but also with shore-based command centers, allied platforms and uncrewed underwater vehicles, ensuring that commanders retain a real-time picture of the battlespace.
Recognizing that undersea threats will continue to evolve, Rohde & Schwarz has designed the architecture to be fully modular and software-defined. In the future, new waveforms, encryption standards, or analytics algorithms can be introduced via over-the-air updates, preserving investment while keeping the fleet ahead of the curve. This scalability also enables rapid integration of emerging technologies such as quantum-secure links and next-generation low-frequency acoustic modems.
