X-47B UCAS-D (2011-2015)
Northrop's X-47B became the first unmanned aircraft to land on an aircraft carrier in 2013. The Navy's Unmanned Carrier-Launched Airborne Surveillance and Strike program was later restructured, and Northrop never received a production contract for the aircraft.
The X-47B proved autonomous carrier operations were possible, but the program ended without a production order.
Northrop demonstrated carrier-based autonomy at sea, but the Navy moved to a different acquisition approach with new vendors.
Like the X-47B, Talon Blue proves autonomous flight is technically possible. The hard part is converting a demonstration into a production contract.
