5 Mile UFO Found at the bottom of the ocean off coast Peru

​Scanning the bottom of the ocean off coast Lima, Peru shows a perfect disk shaped object with a diameter of 6,4km that seems out of place compared to the surrounding ocean floor. 
Could it be: 
1. A huge flying saucer (UFO_USO) that floats above a black hole.
2. A solid construction that can open and close leading to an underwater base.

If you look carefully at the 5 mile UFO, you will see a dome structure at its center that is higher than the rest of the disk. Thats the classic disk design we have all heard about.
