It's very difficult to know.
One of the major issues with regard to the over-the-pole or over-the-horizon polar radar system they're talking about is dealing with atmospheric interference: the aurora borealis, to be blunt. The government did invest and did give a contract to Raytheon Canada to look at the over-the-horizon system, but I don't know the results of that development and test procedure.
It's certainly something that needs to be moved forward. As I said, if you go back to 2011, that really was the date when this should have started to move forward, but we've been delayed and delayed and delayed. NORAD modernization was identified in 2017. No funding was provided. There are a lot of reasons behind that, but yes, we lag behind, and we will stay behind for a long period of time.
