U.S. Navy Personnel Practice Test

AEDO stands for Acquisition and Engineering Duty Officer, a Navy officer who guides the end-to-end management of major acquisition programs. The role focuses on air weapon systems, which includes aircraft, space-based assets, and the weapons that arm them. This encompasses the full lifecycle—from defining requirements and design through development, testing, production, deployment, and sustainment—while balancing cost, schedule, and performance to meet warfighter needs. The other options describe narrower domains: surface weapons, ground vehicles, or submarine propulsion, which fall outside the typical scope of this AEDO focus. Think of programs to procure new aircraft or aerial/space weapons, and you see why air weapon systems is the best fit.
