The US Navy’s unmanned X-47B returned to carrier operations aboard USS Theodore Roosevelt (CVN 71) Aug. 17 and completed a series of tests, operating safely and seamlessly with manned aircraft. Building on lessons learned from its first test period aboard TR in November 2013, the X-47B team is now focused on perfecting deck operations and performing maneuvers with manned aircraft in the flight pattern.
“Today we showed that the X-47B could take off, land and fly in the carrier pattern with manned aircraft while maintaining normal flight deck operations,” said Capt. Beau Duarte, program manager for the Navy’s Unmanned Carrier Aviation office. “This is key for the future Carrier Air Wing.”
The first series of manned/unmanned operations began this morning when the ship launched an F/A-18 and an X-47B. After an eight-minute flight, the X-47B executed an arrested landing, folded its wings and taxied out of the landing area. The deck-based operator used newly developed deck handling control to manually move the aircraft out of the way of other aircraft, allowing the F/A-18 to touch down close behind the X-47B’s recovery.
This cooperative launch and recovery sequence will be repeated multiple times over the course of the planned test periods. The X-47B performed multiple arrested landings, catapults, flight deck taxiing and deck refueling operations.
“The X-47B has again pushed the boundaries of the UCAS program by demonstrating that it can operate seamlessly with conventional carrier assets in one of the most demanding environments in the world,” said Capt. Beau Duarte, the Navy’s UCAS program manager.
During the flights, the X-47B flew in the landing pattern with the F/18-Hornet at approach speeds of 120 miles per hour, at a pattern altitude of 1,200 feet. Mission operators aboard the USS Theodore Roosevelt had full control of the X-47B during flight maneuvers that involved several planned precision approaches to the carrier.
“Today’s operation proved once again that the X-47B is a mature, reliable system that can integrate safely and effectively with manned carrier operations, both on the deck and in the air,” said Carl Johnson, vice president and Navy UCAS program manager, Northrop Grumman Aerospace Systems.
At the completion of the manned/unmanned flight trials, the X-47B landed safely aboard CVN 71, catching and quickly releasing the arresting cable before folding its wings and taxiing clear of the landing area.
“For this test period, we really focused on integration with manned aircraft,” said Lt. Cmdr Brian Hall, X-47B flight test director. “We re-engineered the tailhook retract actuator and updated operating software to expedite wingfold during taxi, both of which reduce time in the landing area post-recovery. Our goal was to minimize the time in the landing area and improve the flow with manned aircraft in the landing pattern.”
“The X-47B’s air vehicle performance, testing efficiency and safety technologies and procedures developed and tested throughout the program’s execution have paved the way for the Navy’s future carrier-based unmanned system capability,” said Rear Adm. Mat Winter, who oversees the Program Executive Office for Unmanned Aviation and Strike Weapons.
The X-47B will remain aboard CVN 71 for the duration of the underway period. It will perform additional cooperative deck and flight operations with F/A-18s and complete night deck handling and flying quality evaluations.
The Navy will continue X-47B flight operations over the next year to refine the concept of operations to demonstrate the integration of unmanned carrier-based aircraft within the carrier environment and mature technologies for the future Unmanned Carrier Launched Airborne Surveillance and Strike system.
