Ajax Vehicles: Noise
The question
To ask the Secretary of State for Defence, pursuant to the Answer of 9 January 2026 to Question 98880 on Ajax Vehicles: Noise, whether concerns were raised by the (a) Defence Science and Technology Lab and (b) Defence Equipment & Support on the accuracy of the findings of the (i) noise and (ii) vibration calculator.
Answered by Luke Pollard
There have been no concerns on the accuracy of the calculator since 2021.
Work was undertaken to address concerns raised about the accuracy of the findings of the calculator from both DSTL and Defence Equipment and Support staff prior to 2021. Recent evidence from testing on platforms demonstrates both the accuracy and the safety factor within the calculator. These concerns were raised five years ago and have been fully addressed.
