"And after the files were accidentally uploaded earlier this week they have since been deleted by the US Navy.
Website links that led to the documents now redirect to the service's homepage.
In one of the most striking encounters, USS Bunker Hill tracked 11 unidentified drones.
The drones - described as "quadcopter style" - ranged in attitude from 1,400ft to a staggering 21,000ft.
Maps published in the files show the drones circling the warship from around 4am to 6pm.
In the area was Hong Kong flagged bulk carrier M/V Bass Strait - who the US vessel attempted to contact but received no response.
It is suspected some of the drone incident may have been attempts to spy on US warships, such as one involved in the USS Paul Hamilton.
The destroyer was sailing to Long Beach when it spotted three drones flying overhead - once again with M/V Bass Strait lurking in the area.
USS Harpers Ferry - a landing ship - was menaced by eight unknown drones, with three of them swooping over the ship at around 500 feet.
Photos included in the documents show one of the objects in the sky, while a map shows the craft flying over the ship's path.
The drones created a "dangerous situation", according to the ship's commanding officer during the encounter from 5.10am to 6.23am.
And another event, saw six objects flying in a "consistent pattern" in an event that lasted one hour and 25 minutes over the USS Zumwalt.
USS Zumwalt is one of the most advanced destroyers in the US Navy, known for its sleek stealth design.
Sailors observed flashing red and green lights close to the ship, and at one point the one of the drones hurtled over the flight."
Now, do we take Werner von Braun's deathbed confession into account here?
Do we trust a paperclip nazi?
