To ask the Secretary of State for Defence what percentage of Hercules C-130 aircraft have been fitted with explosive suppressant foam. (226997)

74 per cent. of the Hercules C-130 fleet has been fitted with explosion suppressant foam (ESF). Those aircraft that have not been fitted with ESF will shortly begin to be retired from service.

All Hercules C-130 aircraft that are routinely deployed on operations in Iraq and Afghanistan are now fitted with ESF.
