Speculation that the US military may be experimenting with anti-gravity vehicles has skyrocketed following the discovery of a patent filed by the US Navy.

The patent reveals details of a vehicle called HAUC, which stands for ‘Hydro Aerospace / Underwater Craft’. As the name suggests, the craft has submersible capabilities to travel underwater on top of its aviation features which would allow it to travel in the air and possibly space.

A closer look at the filing also shows that the craft moves at extreme speeds by reducing its mass and thereby lessening inertia. Everyone from scientific researchers to conspiracy theorists have posited that this kind of technology would be necessary to allow for the kind of craft movements described in UFO sightings.

Keep in mind that this doesn’t confirm that any alleged UFO sightings actually happened – only that the methods of travel outlined in the patents is similar to theories inspired by those accounts.

Some have also posited that the inspiration for the patent could have been provided by research into black holes, such as an experiment into black hole collisions wherein gravitational waves might have been generated.

According to the patent, “It is possible to reduce the inertial mass and hence the gravitational mass, of a system/object in motion, by an abrupt perturbation of the non-linear background of local spacetime.”

Illustrations of the craft feature a cavity wall containing gas that vibrates through the use of electromagnetic waves, thus creating a vacuum around the craft allowing it to propel itself at high velocities.

While there is no indication that the HAUC is even in production, given that President Trump’s Space Force is well underway it wouldn’t be unreasonable to assume this craft may eventually play a role in US military operations.
