subsequently rescued. Colonel Church amassed more than 500 missions in the F-4. He retired in 1990. Fleet Eligible fleet platforms for NFOs are as of August 2022 are as follows: E-2C/D Hawkeye F/A-18F Super Hornet EA-18G Growler EP-3E Aries II P-8A Poseidon E-6B Mercury MQ-4C Triton (unmanned aircraft, remotely piloted) In the EA-18G Growler, NFOs are designated as electronic warfare officers (EWOs) and may also be mission commanders. In the E-2C Hawkeye and E-2D Advanced Hawkeye, NFOs are initially as designated radar officers (RO), then upgrade to air control officers (ACO) and finally to combat information center officers (CICO) and CICO/mission commanders (CICO/MC). In the E-6B Mercury, NFOs are initially designated as airborne communications officers (ACOs), then upgrade to combat systems officers (CSOs), and finally to mission commanders (CSO/MC). In the EP-3E Aries, NFOs are initially designated as navigators (NAV) and eventually upgrade to electronic warfare officer/signals evaluator (EWO SEVAL) and EWO/SEVAL/mission commander (SEVAL/MC). In the F/A-18D Hornet, the NFO position is known as the weapon systems officer (WSO) and may also be mission commander qualified. Flown only within the U.S. Marine Corps, the last Marine Corps officers to be assigned to the F/A-18D as WSOs received their NFO wings in 2022. The F/A-18D will be eventually replaced in Marine Corps service with the single-seat, STOVL, F-35B Lightning II. In the F/A-18F Super Hornet, the NFO position is known as the weapon systems officer (WSO) and may also be mission commander qualified. In the P-8A Poseidon, the NFO is initially designated as a co-tactical coordinator (COTAC) and upgrades to tactical coordinator (TACCO) and then TACCO/mission commander (TACCO/MC). A single USN or USMC NFO is assigned to the United States Navy Flight Demonstration Squadron, the Blue Angels, as "Blue Angel #8", the Events Coordinator. This is an operational flying billet for this officer and he or she previously flew the twin-seat F/A-18D "Blue Angel 7" aircraft (which had replaced the F/A-18B previously used), and now flies the twin-seat F/A-18F "Blue Angel 7" aircraft with the team's advance pilot/narrator. They function as the advance liaison (ADVON) at all air show sites and the events coordinator provides backup support to the narrator during all aerial demonstrations. NFOs have also served as instructors in the twin-seat F-5F Tiger II at the Navy Fighter Weapons School (now part of the Naval Aviation Warfighting Development Center (NAWDC)) and as instructors in twin-seat F/A-18Bs and F/A-18Fs in
