Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what period of time elapsed between the provision of the Institute for Naval Medicine's report on AJAX to his Department and the cessation of the assessment of the AJAX armoured fighting vehicle.

The full Institute for Naval Madicine report was received in late November 2020 after acceptance and conversion activity had been stopped.

The Institute for Naval Medicine's assessment of Noise and Vibration within the Ajax platform was conducted in August 2020. An initial report was provided in September 2020 which prompted the Army's Environmental Monitoring Team, together with Dstl, to conduct a specific assessment of in-ear noise in October 2020. The initial findings of this assessment resulted in a halt to all acceptance and conversion activity in early November 2020.
