Side number 555, the 100th P-8A Poseidon delivered to the Navy, taxis shortly after arriving at Naval Air Station Jacksonville, Fla. May 14, 2020. The program to replace existing maritime patrol aircraft like the P-3C Orion with the P-8A Poseidon has remained ahead of schedule and under budget for nearly its entire existence. The P-8A is capable of broad-area, maritime and littoral operations, and is also successful at search and rescue. (Photo courtesy Navy)
