I think the navy has to make a firm decision: this is what we want—point final.
The problem with defence technology is that it's moving so fast. We're on the brink of Star Wars, literally, with a whole world of drones in the sky, in the sea, on the surface, and so forth fast coming up over the horizon. I can understand why navies succumb to the seduction of one more widget or one more whatever. In some cases, it's visited upon them when they suddenly discover that the enemy has a certain type of weapon system that they have to counteract.
Then, I think, so far as possible, you have to have someone in charge.
