The War Zone – Another long-serving U.S. military aircraft has completed its final operational deployment, with the return of the U.S. Navy’s EP-3E Aries II surveillance platform from the 5th Fleet area of operations. The countdown to the spy plane’s final retirement is now on, which will see its vital intelligence, surveillance, and reconnaissance (ISR) mission handed over to the P-8A Poseidon maritime patrol plane, the MQ-4C Triton high-altitude, long-endurance drone, and other assets, including ones in space.
