The lack of any mention of a major military conflict on nytimes.com, cnn.com, and news.google.com is a pretty good indication. You don't need to care about a half-finished GNSS system if you're just bombing ISIS.
Unless you wanna kill it before it is deployed. For example if the U.S. was aware that a nation state was about to pull out on funding for it and wanted to keep the economic dominance of GPS.
Mexican drug wars are violent but do not involve competing state militaries, so I would not call it a major military conflict. It's a criminal problem being solved using the military.
