What you’re looking at is one of the three pillars of America’s bomber force, the B-2 Spirit. This particular one flies out of Whiteman Air Force Base in Missouri, and during this particular mission, which took place at the end of June (the pic was recently released by the USAF), it linked up with a KC-135 Stratotanker flying out of MacDill Air Force Base, Florida, for a refueling mission.
As it usually happens during such missions, someone on board the Stratotanker snapped a pic of the bomber, one that, with just the smallest amount of zoom, paints a very detailed picture of the B-2, down to the markings it wears all over.
The markings are mostly there to instruct maintenance personnel where to step and what areas to avoid while moving on the plane for whatever reason. The engine intakes are also clearly visible in the pic, and so are some small and unrevealing parts of the cockpit where normally the two pilots sit.
When captured on film over Oklahoma, the plane was not hooked to the refueling boom, so the connector high up on the fuselage is visible as well, while the boom is conveniently obscuring some parts of the plane.
