F. E. WARREN AIR FORCE BASE, Wyo. -- 20th Air Force completed Sentinel Dragon 26-02, a commander-directed, no-notice exercise conducted from August 4-7, 2026, designed to validate the combat readiness of its missile wings.
By removing the benefit of traditional spin-up time, leadership was able to observe exactly how operations, maintenance, and security forces teams react and execute under pressure.
"An effective nuclear deterrent must be ready 24/7/365, and Sentinel Dragon proved that our standard, day-to-day posture is highly lethal and fully prepared,” said Maj. Gen. Colin Connor, 20th AF commander. “Readiness is not a state we ramp up to achieve on test day- it is our baseline operational standard. Seeing our teams integrate seamlessly with zero prior notice is a testament to the professionalism of our Airmen and proves we fight as one unified, highly lethal 20th Air Force team."
The defining characteristic of Sentinel Dragon was the intentional lack of advanced preparation. Because only a restricted circle of planners knew the exercise was impending, units were forced to rely entirely on their raw, day-to-day command and control channels. This dynamic environment challenged participants to solve complex problems on the fly, proving the force is capable of mobilizing and fighting at any given moment.
The operational assessment focused on three primary capabilities: Missile Procedures Trainer spot evaluations for operators, maintenance execution under pressure, and a complex Launch Facility recapture by security forces.
"The biggest success was simply proving we can execute a complex, multi-wing exercise with zero notice," said Maj. Jared Lynd, 20th AF Exercise Branch chief. "Our ops crews performed exceptionally well under pressure."
A critical component of Sentinel Dragon was validating the proficiency of first-tour crew members, who form the operational foundation of the force. The simulator scripts, strictly adhering to governing directives, tested operators against exacting performance criteria. By succeeding in these high-pressure scenarios, operators validated their ability to perform every step exactly as technical orders dictate, reinforcing the muscle memory required for safe, secure, and effective nuclear operations.
The Launch Facility recapture scenario perfectly demonstrated the necessity of total-force integration. Defenders successfully managed complex airspace, mitigated a simulated drone threat, and coordinated with the 582nd Helicopter Group for tactical insertion and air support. The integration of rotary-wing assets directly into ground tactical plans proved to be a massive force multiplier, proving the 20th AF fights as one unified and integrated team.
Simultaneously, operations and maintenance personnel worked securely in the capsule and the field to ensure the weapon system remained mission-capable.
Every observation during Sentinel Dragon served as an opportunity to refine tactics and procedures. Moving forward, 20th AF will continue to streamline training infrastructure at the headquarters level by standardizing simulator scripts and products across missile wings. This shift intends to give instructors hundreds of administrative man-hours back, allowing trainers to focus purely on enhancing warfighter lethality.
