A Naval Air Systems Command P-8A Poseidon comes in on approach to the boom arm of a 459th Air Refueling Squadron KC-135R Stratotanker over the Atlantic Ocean April 13, 2017. This was the first operational inflight refueling of a P-8A. The P-8A is the second-ever Navy aircraft to be fitted with a receiver for aerial refueling; the first being the E-6B Mercury nearly 30 years ago. (U.S. Air Force photo/Tech. Sgt. Kat Justen)
