Navy Bolsters Platforms with 5G, Eyes Ship-to-Ship Connections

Why It Matters

Broad 5G adoption will give the Navy faster data exchange, enhancing mission agility and joint operations, while solving spectrum constraints is critical for sustained maritime superiority.

Key Takeaways

• Navy aims 5G on all platforms, from drones to carriers.
• Testing ship‑to‑shore 5G shows high‑speed, low‑latency data.
• Sidelink considered for ship‑to‑ship, but commercial deployment limited.
• Private 5G rollout targets remote bases, e.g., Twentynine Palms.
• Spectrum allocation varies by location, complicating naval communications.

Pulse Analysis

The push to embed 5G across the fleet reflects a broader defense trend toward network‑centric warfare, where real‑time data drives decision‑making. By integrating commercial‑grade radios and private 5G infrastructure, the Navy can reduce reliance on legacy satellite links, cutting latency from seconds to milliseconds. This shift not only improves situational awareness for individual vessels but also enables coordinated actions among unmanned systems, surface ships, and aircraft, creating a more resilient and adaptive force posture.

Ship‑to‑ship communications represent the next frontier. While the 5G standard includes sidelink—a direct device‑to‑device protocol—its civilian rollout has stalled, prompting the Navy to evaluate hybrid mesh solutions and NATO‑tested alternatives. Successful ship‑to‑shore trials demonstrate the potential for high‑throughput, low‑latency links that could support everything from collaborative sensor fusion to secure tactical messaging. Achieving reliable at‑sea mesh networks would dramatically shorten the decision loop in contested environments, giving U.S. forces a decisive edge.

Spectrum scarcity remains a strategic bottleneck. The Navy’s policy group is crafting dynamic allocation frameworks that adjust frequencies based on operational context—harbor, open ocean, or allied ports. By leveraging private 5G and emerging Open Radio Access Network (ORAN) architectures, the service can supplement limited government bands with commercial spectrum, ensuring continuous coverage even in remote or austere locations. This flexible approach not only mitigates interference risks but also positions the Navy to adopt future generations of wireless technology without costly infrastructure overhauls.
