Sighting Rhode Island

I just saw some shit. Driving over the Jamestown bridge Rhode Island, a large triangular shaped object coasted over head about 100 yards away. It was on stage for me. It was darker than the sky. 3 large lights and many smaller. It was low flying and slowly coasting across. It was clear as ever for moments as I stared in disbelief at what I was watching. It was coming from the naval airfield near by in Quonset. It was very large and solid and angular. It had no propellers or wings or propulsion of any sort. It coasted. I thought of maybe a balloon or drones or even a blackbird as there is a military presence local and nothing could describe the menacing hover of this giant. I got a late picture as I was in awe.
The pictures were after it had sailed by to the right of the bridge. It came across my view over the bridge at slow speed. I feel as if the men in black are gonna show up it was so clear. If you saw it hit me up. I have a video but the 3rd pic has the triangular shape to it clearest. First pic you can see a corner.
