The US is having difficulties testing autonomous maritime drones, with recent incidents highlighting software and communication problems.

Recent tests of the Pentagon's autonomous maritime drones have revealed significant problems, including software glitches and faulty communication. The incidents, which occurred during tests off the coast of California, led to unexpected shutdowns of the ships and even the capsizing of some support craft. Despite these setbacks, the Pentagon continues to invest in the Replicator program, aiming to purchase thousands of drones to boost naval capabilities in the face of challenges from China.
