The U.S. Navy is drafting new guidelines for pilots and other employees to report encounters with "unidentified aircraft."

The new effort comes in response to more sightings of unknown, advanced aircraft flying into or near Navy strike groups or other sensitive military facilities and formations, according to the service.

"There have been a number of reports of unauthorized and/or unidentified aircraft entering various military-controlled ranges and designated airspace in recent years," the Navy said in a statement to Politico, which first reported the move.

"For safety and security concerns, the Navy and the [U.S. Air Force] takes these reports very seriously and investigates each and every report."

"As part of this effort," it told Politico, "the Navy is updating and formalizing the process by which reports of any such suspected incursions can be made to the cognizant authorities. A new message to the fleet that will detail the steps for reporting is in draft."

The initiative comes amid increasing interest from lawmakers and the public following the release of classified files from the Defense Intelligence Agency that revealed the funding of projects that investigated UFOs, wormholes, alternate dimensions and other obscure topics that typically leads to the conspiracy-theory fringes of the web.
