The Office of Naval Research uses ____________ and ____________ input to assist in guiding research and development funding.

The correct choice highlights that the Office of Naval Research (ONR) relies on input from both the Fleet and OPNAV (Office of the Chief of Naval Operations). The Fleet represents the operational Navy that provides insights into the immediate and practical needs associated with naval operations, technology, and capabilities. OPNAV, on the other hand, provides strategic guidance and oversight for naval operations, ensuring that research and development align with broader naval objectives and policies.

Together, the input from the Fleet and OPNAV allows the ONR to make informed decisions regarding the allocation of research and development funds, focusing on areas that will enhance naval capabilities and readiness. This collaboration ensures that funding priorities are based on real-world operational requirements as well as strategic vision, ultimately leading to advancements in technology and capabilities that benefit the entire Navy.
