The fundamental issue is whether we need costly aircraft requiring pilots and crews to carry out surveillance. This is quite an important issue. I have always been a staunch defender of new technology and unmanned aerial vehicles. I think it would cost much less to maintain that kind of surveillance fleet. I simply wanted to add that.
We have had a discussion about submarines. Part of the rationale for having submarines was that they would be used to carry out surveillance in the Far North. However, that could be done with a fleet of unmanned aircraft.
For the time being, I want to stick with the suggestion I've made. Let's do a review of the Aurora to see whether things are going well or not. If a change occurs in the meantime, we can always add the other part that was suggested earlier.
