Designed as autonomous or semi-autonomous ships that can be deployed without a crew, alone, in packs or combined with manned combat vessels, these long-endurance stealth platforms can be very heavily armed, with for example numerous anti-ship missiles, surface-to-air systems, artillery, anti-submarine warfare capabilities or even the deployment of other drones. We can well imagine them providing a first defensive curtain off the coast, conducting interdiction missions, contributing to a protective bubble for an aircraft carrier group or even conducting raids on enemy targets.
