Northrop Grumman, U.S. Navy Test Autonomous Aerial Refueling for Unmanned Combat Air System Demonstration

Northrop Grumman and the U.S. Navy have successfully completed a series of flight tests to demonstrate technology that could help extend the operating range and flight duration of future carrier-based unmanned systems.

The flight tests, completed Jan. 21 in St. Augustine, proved the functionality of the hardware and software that will enable the X-47B unmanned aircraft to demonstrate autonomous aerial refueling (AAR) in 2014.

The AAR activity is part of the Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program. Northrop Grumman is the Navy's UCAS-D prime contractor.

"These tests are a critical step toward proving that the X-47B can perform autonomous aerial refueling using either the Navy's probe-and-drogue refueling technique or the U.S. Air Force's boom/receptacle approach," said Carl Johnson, vice president and UCAS-D program manager for Northrop Grumman's Aerospace Systems sector.

"Future unmanned systems will need to use both refueling techniques if they plan to conduct longer range surveillance or strike missions from the carrier."
