This brings us back to the question of why did the US Navy recall all its aircraft carriers in early 2017, and forge ahead with plans to build the larger and more expensive Ford-class carriers?

For an answer, we need to review a 2018 patent awarded to a Navy scientist, Salvatore Cezar Pai, which is titled: “The High Energy Electromagnetic Field Generator” (HEEMFG). In a previous article, I briefly described his patent as an electromagnetic shield. The patent’s summary describes one of the goals of the HEEMFG is to protect the Earth from potential asteroid impacts:

It is a feature of the present invention to provide a method and apparatus for deflecting or destroying a large asteroid and preventing a possible collision with earth. The present invention may also deflect or destroy any other type of object.

It is the HEEMFG’s ability to “deflect or destroy” fast traveling objects which directly pertains the question of why the Navy recalled all its aircraft carriers and is moving ahead with building more Ford-class carriers:

It is a feature of the present invention to provide a method and apparatus for generating an impenetrable defensive shield to Sea and Land as well as Space-based military and civilian assets, protecting these assets from such threats as Anti-Ship Ballistic Missiles, Radar Evading Cruise Missiles, Top Attack for Main Battle Tanks (land and sea based systems), as well as counteracting the effects of solar-induced Coronal Mass Ejections or defending critical military satellites in an ASAT role (space based system).

The development of an impenetrable electromagnetic shield to defend a target from fast traveling objects such as asteroids and missiles is very similar to ideas first proposed by the Serbian inventor Nikola Tesla back in the 1930’s, Tesla proposed an electromagnetic shield based on scalar wave principle which has been explained as follows:

Scalar Waves can be warped into a dome around objects, such as cities or houses… Such a Scalar Wave force field is generally known as a Tesla Shield, and it would be analogous to the “shields” referred to in the popular “Star Trek” series. Tesla Shields have a definite defensive application, and could not in any way be used for offensive purposes (although a platoon of soldiers charging into a Tesla Shield would be instantly disintegrated). The only defense from a blast of a Scalar Wave Howitzer would be a Tesla Shield.
