Aviation News – Sierra Nevada Corporation (SNC) has launched test flights for the U.S. Air Force’s Survivable Airborne Operations Center (SAOC), a next-generation airborne command post designed to ensure secure operations in crisis scenarios.
According to SNC, the first test flight took place on August 7, just five months after the company began work on the initial airframe. The SAOC program involves converting Boeing 747-8i aircraft acquired by SNC to replace the Air Force’s aging E-4B “Nightwatch” fleet, which has served as the airborne command and control hub since the 1970s.
The SAOC is designed to withstand advanced threats, including electronic warfare and nuclear events, while maintaining secure communications between U.S. leadership, military commanders, and strategic forces. By leveraging the Boeing 747-8i platform, the aircraft combines modern avionics and long-range capability with extensive modifications tailored to survivability and command operations.
“The SAOC program represents a critical capability for the United States, ensuring that national command authority can operate and communicate under any circumstances,” SNC said in a statement.
Further test flights and integration work will continue in the coming months, leading toward full operational capability later this decade. The program is seen as essential to modernizing U.S. strategic command and ensuring continuity of government operations during global crises.
The milestone underscores the Air Force’s commitment to replacing legacy systems with more resilient platforms. With the SAOC entering its testing phase, the U.S. is one step closer to fielding a new generation of secure airborne command centers.
