Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many soldiers were hospitalised or received hearing-related injuries in relation to the Ajax programme since 23 July 2025.

Since 23 July 2025, centrally held electronic systems show fewer than five personnel have had a hospital admission recorded since their first use of Ajax. None of these were related to Ajax, hearing or vibration.

In the same period, 27 personnel have had a hearing loss related read code entered into their electronic medical record since their first use of Ajax. However, the presence of read code does not imply either a long-term problem or that it has been caused by their use of Ajax. For any Service person their use of Ajax will be mixed with other potential sources of exposure. It is also possible that symptoms are not occupationally related.
