I don't know if this feature will be in the in the full release but as i seen no news of this i decided to to post this for the feature.

First off all i feel this feature should be in the game as we have unmanned drones for both aerial, and land.I feel that having a drones for the sea will be useful as they can be use to lunch missile sort of the same as the greyhawk, or be used as a patrol, and recon,
