Not really - you need thousands of pounds of ordinance to sink a destroyer and no small UAV is carrying that.

The UAV could be the first part of a coordinated attack... it could do something to foul the sensors on the ship, for example.

Did you see some representation of size?

Based on the flight times and 100 mile flights ~100 miles off the coast and the investigated boats in the area...they couldn't be small. At least not with current consumer battery technology. Maybe if they were launched by a sub?

There's a youtuber that has a multi-hour autonomous drone, but it's solar powered and this was at night.

That could almost had done what’s reported from land, and easily from a small boat 50 miles away from the ships (which is well over the horizon).
