Angus Robertson – 2014 Parliamentary Question to the Ministry of Defence

The below Parliamentary question was asked by Angus Robertson on 2014-06-16.

To ask the Secretary of State for Defence, what the loudest decibel levels are that are produced by JSF 35B during operations aboard an aircraft carrier.

Mr Philip Dunne

The loudest operation to be conducted by the F-35B onboard an aircraft carrier is a Military Power take-off. The measured aircraft sound level of a Military Power take-off is approximately 145 dB at 135 degrees from the aircraft nose centre line, at a distance of 50 feet from the rear of the aircraft. The Military Power take-off is a standard operating procedure and managing exposure to noise is an integral part of normal embarked operations. This level of noise is similar to that of the Harrier, F18’s, F15’s and the same level as produced by an F-16.
