Question to the Ministry of Defence:

To ask the Secretary of State for Defence, by what date SONUS acoustic weapon detection will be issued to 5th Regiment Royal Artillery.

The SONUS system is an Acoustic Weapon Locating capability and part of a wider programme which is delivering the next generation of Weapon Locating Systems.

The first SONUS equipment delivery date has been accelerated and is now currently scheduled for early 2026, five years earlier than planned. This equipment will be issued to 5^th Regiment Royal Artillery for use in training and User Acceptance Trials. Full Deployable Capability is forecast for early 2027.
