Navy Drone Program Struggles Amid Tests and Setbacks

The U.S. Navy is trying to build robot boats that can move and fight on their own, but they're having some trouble.

In recent tests, some boats crashed due to software and communication problems.

The goal is for these boats to work without needing people to control them, but it's proving difficult.

The Navy's program is also dealing with issues like the firing of a leader and a review of the whole project, partly because it's expensive.

The Pentagon is buying many drones through a program called Replicator, but the Navy's part of this is facing setbacks.
