Okay kiddo, so you know how there are people who work for the navy and they help make plans and decisions about what the navy should do? Well, there's a special group of people who are really smart and have lots of experience that the navy asks for advice. That group is called the Naval Research Advisory Committee, or NRAC for short.
The NRAC is made up of a bunch of experts in different fields like science, engineering, and technology. They help the navy figure out how to use new ideas and technology to make better ships, airplanes, and other things the navy uses. They also help the navy figure out how to stay safe when they're out in the ocean.
So basically, the NRAC is a group of really smart people who help the navy do better at their job.
