Moving on into the sort of sensors and the electronics side, erm  for survivability  erm  the defensive aid sub- system will be  er very complex, very sophisticated but also integrated so that it has a complete system of protection for the aircraft, erm  an and  finally moving on on the sort of electronics side then clearly with different sensors such as the radar, the forward looking infra-red, infra-red search and track  the er multiple information distribution system and also certain aspects of the er  electronic warfare suite then by having sensor fusion which enables the best information at any one time to be  correlated into the system as a whole then that will provide a very  good capability and far in excess of anything that we have at the moment.
