Those sound at least a little bit better than one armed rocket with nine spare rockets for parts. How many chances do you get to fix a rocket that doesn’t work? And one would hope that all the warheads were functional since the spares are missing that item.
I dont know on what basis these warheads are deemed non functional and the article doesn’t say.
If they are simply over-aged and deemed unusable, and not somehow dismantled, the Ukrainians may just use them as is. The Canadians may be too picky but the Ukrainians probably aren’t. Both sides have long been using overaged ammo from disparate sources.
