About SNN Portsmouth

SNN Portsmouth, formally known as the Signal and Navigation Network Portsmouth, was established in the early 1940s as a critical communications and navigation support unit for the Royal Navy based in Portsmouth, England. During World War II, the unit played a pivotal role in coordinating naval operations in the English Channel, providing secure signaling, and supporting Allied amphibious landings, most notably during the D-Day invasion. In the Cold War era, SNN Portsmouth adapted to emerging technologies, focusing on electronic warfare and advanced navigation systems. Today, the unit remains at the forefront of naval communication innovation, supporting fleet readiness and operational security for the Royal Navy.
