EXCLUSIVE: Secret New UAS Shows Stealth, Efficiency Advances (excerpt)

A large, classified unmanned aircraft developed by Northrop Grumman is now flying—and it demonstrates a major advance in combining stealth and aerodynamic efficiency. Defense and intelligence officials say the secret unmanned aerial system (UAS), designed for intelligence, surveillance and reconnaissance (ISR) missions, is scheduled to enter production for the U.S. Air Force and could be operational by 2015.

Funded through the Air Force’s classified budget, the program to build this new UAS, dubbed the RQ-180, was awarded to Northrop Grumman after a competition that included Boeing and Lockheed Martin. The aircraft will conduct the penetrating ISR mission that has been left unaddressed, and under wide debate, since retirement of the Lockheed SR-71 in 1998.

Neither the Air Force nor Northrop Grumman would speak about the classified airplane. When queried about the project, Air Force spokeswoman Jennifer Cassidy said, “The Air Force does not discuss this program.”

The RQ-180 carries radio-frequency sensors such as active, electronically scanned array (AESA) radar and passive electronic surveillance measures, according to one defense official. It could also be capable of electronic attack missions.

This aircraft’s design is key for the shift of Air Force ISR assets away from “permissive” environments—such as Iraq and Afghanistan, where Northrop Grumman’s non-stealthy Global Hawk and General Atomics’ Reaper operate—and toward operations in “contested” or “denied” airspace. The new UAS underpins the Air Force’s determination to retire a version of the RQ-4B Global Hawk after 2014, despite congressional resistance. The RQ-180 eclipses the smaller, less stealthy and shorter-range RQ-170 Sentinel. (end of excerpt)
