A US Navy video of one of their Pacific Fleet task force aircraft carriers surrounded by a swarm of UFOs travelling at high speed and subsequently disappearing into the sea, has now been explained.

It turns out the UFOs were in fact a fleet of Amazon drones delivering vodka to a Russian submarine that was shadowing the US task force.

A spokesperson for Amazon told FNN:

We received an unusually large order for vodka from an address off the coast of San Diego and decided the most appropriate way to deliver the package - as the person placing the order was an Amazon Prime subscriber - was by drone.

This required us to send a fleet of drones to fulfil the order and because the recipient happened to be located right underneath the USS Nimitz at the time, this explains why so many objects were picked up by Navy radar and observed diving into the ocean like kamikaze Cormorants.
