The Los Angeles Times is reporting the Pentagon intends to develop a giant dirigible that will float 65,000 feet above the stratosphere with a shelf-life of ten years.

The unmanned airship will provide “unblinking and intricate radar surveillance of the vehicles, planes and even people below”.

It will be a “cross between a satellite and a spy plane.”

The 450-foot-long craft would give the U.S. military a better understanding of an adversary’s movements, habits and tactics, officials said.

The Pentagon has not yet awarded a contractor to build the prototype. Earlier work was done by Northrop Grumman and Lockheed Martin.
