I don't know. Yes, it's possible. The only company I'm aware of that has been actively involved in the last decade or so with ballistic missile defence was Raytheon, which proposed the installation of an x-band radar at Goose Bay as a Canadian contribution, if you will, toward ballistic missile defence before the decision was taken not to participate. Of the companies I currently work with, there's no substantive work we do that has anything to do with ballistic missile defence, and I think I'm right in saying not even NORAD.
