In October 2025, the Royal Navy conducted a milestone trial that could reshape under-sea operations. A quantum optical atomic clock — the Tiqker system developed by Infleqtion — was installed aboard the extra-large uncrewed underwater vehicle XV Excalibur, marking the first time such a device has been deployed at sea on a submarine platform.
This breakthrough is far from a novelty gadget. Submarines navigating in remote or contested waters face a persistent challenge: once submerged, they often lose reliable access to satellite navigation (GNSS/GPS) and must rely on inertial systems whose errors slowly accumulate over time. In that context, a high-precision clock onboard becomes more than a timing reference — it becomes the heartbeat of all positional, timing, and sensor systems.
In this video, Defense Updates analyzes why Royal Navy’s test of quantum optical atomic clock is a big step for submarines ?
