The Experimental Airworthiness Certificates allow Raytheon's flight operations to continue in compliance with recently published FAA policy on unmanned aircraft operations in the National Airspace System.

Raytheon says Cobra is a low-cost unmanned system designed to support the company’s development, integration and test of unmanned systems technologies. The aircraft has a wingspan of 10 feet and is 9-feet long.
