Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many instances of vibration sickness have been recorded with a) Ajax, b) Ares, c) Athena and d) other Ajax-variants since 6th November 2025.

Safety of personnel is a top priority for me. As reported to the House in my recent Written Statement dated 26 November. On 22 November, during a routine training exercise, around 30 soldiers operating in Ajax reported being affected by noise and vibration exposure. Out of an abundance of caution, and in line with our safety protocols, the exercise was halted within 30 minutes so that those affected could receive appropriate medical care. Importantly, none of the symptoms were severe enough to require hospitalisation.

Of the 61 vehicles of all AJAX types were involved in the exercise, 23 AJAX Vehicles were linked to soldiers suffering from noise or vibration injury.
