The flip answer is no, there's not. If you do not have the subs, increasingly you're not going to have the deterrence capability. You're not going to have that psychological factor over subs coming into our waters. They're saying, “Okay, we don't know where the Canadian subs are.” That's first and foremost. If you lose that, you lose 80%.
The alternative is to ensure that programs such as Northern Watch, which is a technological program we have to develop an indigenous capability of listening for subs under the water.... It's through acoustics that you listen for subs. That program is ongoing, but it's in spits and starts. We would need to have a much more extensive deployment of that type of SOSUS system, but one that is a much more independent system.
We're developing the technology. Will we actually make it operational and deploy it? Stay tuned on that one.
