On March 25, 2026, Firefly Aerospace announced its participation in two major responsive space exercises for the U.S. Space Force (USSF) as part of the VICTUS DIEM mission.

Supporting prime contractor Lockheed Martin, Firefly demonstrated the rapid-turnaround capabilities essential for Tactically Responsive Space (TacRS) operations—a critical requirement for national security in contested orbital environments.
The exercises focused on compressing the traditional months-long launch preparation cycle into a matter of hours. By successfully simulating emergency protocols and rapid payload integration, the mission aimed to codify a repeatable, commercial-government process for deploying space assets on demand.
Responsive Space Exercise Milestones
The VICTUS DIEM mission was structured into two distinct operational demonstrations:
- Rapid Payload Processing: The team completed all spacecraft arrival operations, health checkouts, mating, and encapsulation in under 12 hours.
- 36-Hour Launch Simulation: Firefly and Lockheed Martin executed a full emergency launch simulation, managing mission design, flight trajectory planning, collision avoidance analysis, and range safety authorizations within 36 hours of receiving a simulated notice to launch.
These drills were conducted in collaboration with Space Systems Command’s (SSC) System Delta 89—the program office known as Space Safari—and SSC’s Space Launch Delta 30 based at Vandenberg Space Force Base.
The Evolution of VICTUS
VICTUS DIEM serves as a process-refinement precursor to other missions in the USSF’s tactically responsive portfolio. While earlier missions like VICTUS NOX (2023) utilized live launches to set records, VICTUS DIEM focused on the organizational and regulatory “paperwork” of rapid flight, ensuring that range safety and trajectory approvals do not become bottlenecks during a real-world threat scenario.
Firefly is also currently preparing for VICTUS HAZE, another TacRS mission scheduled for later in 2026. That mission will see Firefly’s Alpha rocket launch a satellite built by True Anomaly to demonstrate on-orbit maneuverability and proximity operations.
Executive Perspective
“This exercise, in close collaboration between SSC, USSPACECOM, and our industry partners at Lockheed Martin and Firefly, proves that critical space capabilities can be delivered on accelerated timelines to meet the most urgent national security and warfighter demands,” said USSF Lt. Col. Cliff Johnson, Space Safari director.
