So I actually put two and two together. I just realized the "BB" on the tail must mean it's from Beale AFB, and the RW stands for Reconnaissance Wing, and that Beale is home to U-2's (and SR-71's back in the day?), and so these planes must be what the U-2 pilots fly to keep current (since operating a U-2, being that it's a limited strategic asset, should be restricted to actual missions and the occasional training).
