The new office was set up earlier this year to track and investigate reports of Unidentified Aerial Phenomena (UAPs).
An ongoing research effort to observe and document UAPs over Ukraine has reportedly turned up quite a lot of sightings.
The move aims to mitigate any potential threat posed by UAPs to nuclear facilities across the continent.
Col Tim Peake, who previously spent time aboard the space station, discussed UAPs during a recent TV interview.
Genuine footage recorded by the pilots of a US Army helicopter shows three unidentified, fast-moving objects.
A previously unreported US Navy encounter with UAPs has been revealed by a former marines officer.
A team of military veterans, scientists and entrepreneurs are aiming to track down 'unidentified aerial phenomena.'
