There are two things, Mr. Chair.
Number one—and the chief may have to help me here—is that there are variants of the 155, and the production of 155s in Canada is not, I'll call it, the most desirable variant. When you talk about upgrading production, we're also talking about new machinery, etc., to make a different type of 155. Discussions are under way, but it's a pretty big investment.
The chief can help me out with variants here.
