"Regarding the bomb bay fire extinguisher issue. The Nimrod has a 'trooping role' and in order to be used in that manner 6 extended range fuel tanks would be fixed in the bomb bay. With this fit 10 fire extinguishers would also be fitted. However, in the normal fit we do not have either the extended range tanks or the fire extinguishers fitted. That means that day to day there is no fire protection in the bomb bay. However, the bomb bay fire drill calls for all stores to be jettisoned, and to my knowledge there has only been one actual bomb bay fire in the life of the ac. This was caused by an electrical fault causing a flare to ignite when power was supplied to the weapons carrier."
