A spy drone named Blue Devil Block 2 is set to fly soon to spy on Afghan skies for surveillance. The Airship is 370 feet long, will house a supercomputer and surveillance equipment, can keep an eye on 36 square miles at time from a height of 20,000 feet+ but will lack on movement speed. It is one of the largest airships produced since World War II. With this spy drone the US military will achieve air supremacy. There are two mega-airships that are currently being built by the military with a  $211 million dollar investment.
