The US Department of Defense released footage of an uncrewed vessel firing a large missile. This was part of the Ghost Fleet Overlord program, which aims to create robot vessels that can work alongside crewed warships.
Ghost Fleet operations in the past have been focused on endurance missions, which included the first uncrewed Panama Canal transit. However, firing is the first sign that the vessels will now be armed.
The SM-6 weapon, a 1500-kilogram missile that travels at Mach 3.5 speed, was used in the demonstration.
