The question

To ask the Secretary of State for Defence, what assessment he has made of the potential impact of levels of (a) noise and (b) vibration on the (i) Ajax, (ii) Ares and (iii) Athena vehicles on the health of service personnel.

Answered by Luke Pollard

As safety of our personnel is the top priority for the Ministerial Team, prior to Ajax Initial Operating Capability being announced, I sought assurances in writing from the Chief of the Defence Staff and the National Armaments Director that the system was safe to operate, which I received..

As such, following the recent incident where noise and vibration symptoms were reported by some personnel operating Ajax, and out of an abundance of caution, I directed a pause on the use of Ajax for training and exercising, while a safety investigation is carried out.

The Defence Accident Investigation Board are working with the Army Safety Investigation Team and General Dynamics at pace to conduct an investigation into the incident.
