Supposedly when the X-37B is on “our side” of the globe, it can dip ever so slightly into the upper atmosphere and ‘stear itself’ into a different orbital plane. The bad guys never know for sure where or when it will pop up. Considering it’s rather small size, it’s probably a tough-acquisition for radar until it’s fairly high over the horizon. By then it’s too late to hide your shit.
That is very cool.
