On 15 September, the Advanced Strategic Capabilities Accelerator launched the Undersea Navigation Challenge.

The Challenge seeks to develop a prototype navigation system for undersea autonomous platforms that can operate without relying on Global Navigation Satellite Systems or acoustic transmissions.

Undersea navigation is a crucial capability for Defence to protect critical undersea infrastructure, enable operations and provide a strategic advantage for the effect of deterrence.

A virtual market briefing for industry occurred on 19 September and the Request For Proposal closed on 3 October, with evaluations underway.
