The "Blue Devil 2" is capable of hovering at 20,000 feet for a week at a time while carrying radars, cameras, radio links and computer processors — the airship can also be fitted with “weapons modules,” according to marketing material. The brochure depicts a rotary launcher fitted with 100-pound Hellfire missiles, capable of hitting pinpoint targets up to five miles away. Originally, the company believed those missions would be carried out overseas. But Mav6, whose key executives include former Blackwater employees, is anticipating growing demand from other government organizations.
