The Air Force Strategic Systems (AFSS) Program Area broadens APL’s deterrence mission contributions to the Air Force, building on more than six decades of experience as integral technical partners of the Navy’s submarine-launched ballistic missile system. Over the past decade, AFSS has expanded its focus to include both the Minuteman III intercontinental ballistic missile (ICBM) and the Sentinel ICBM weapon systems, as well as nuclear mission assessments for the Navy and interactive simulations for the Air Force.

AFSS provides critical science, engineering, analytical, and subject-matter expertise to advance the operations, sustainment, development, and testing of ICBM systems. We maintain independent evaluation and assessment capabilities across multiple weapon systems, helping ensure safe, secure, effective, and credible deterrent forces and technically sound solutions throughout each system’s life cycle.

The Trident Strategic Weapon Systems (TSWS) Program Area contributes to the credibility and resilience of the Trident strategic weapon system through engineering, testing, and independent evaluation of both deployed systems and future capabilities. This work includes rigorous test and evaluation, as well as system modifications and evolutionary improvements to the operational fleet. These efforts inform the development and integration of critical capabilities that ensure the Trident system continues to meet evolving requirements.

The TSWS Program Area is integral to the operation, sustainment, engineering, flight-test planning, and independent evaluation of the submarine-launched ballistic missile system – providing comprehensive insight into the sea-based leg of the nation's nuclear triad.

Our analyses and assessments, grounded in an understanding of evolving adversary capabilities and potential technology disruptions, help ensure the Trident strategic weapon system remains resilient and reliable through the rest of the century.

The Regional Deterrence Capabilities (RDC) Program Area enhances the credibility and resilience of U.S. conventional and nuclear deterrence by enabling assured, survivable capabilities aligned with regional mission needs. RDC efforts span weapon system development; platform integration, assessment, and system evolution; and rigorous test and evaluation to accelerate the maturation of critical capabilities.

The program area advances hypersonic weapons delivery, engineers the development of presidential-level response options, and enables strategic recapitalization through increased test cadence and targeted capability enhancements. Drawing on deep technical expertise and a system-of-systems perspective, RDC experts address expanding mission demands and counters evolving adversary threats across contested operational environments.

The Advanced Strategic Capabilities Program Area identifies and develops the critical technologies needed to strengthen the performance and resilience of strategic weapon systems. These technology advancements address current and emerging capability gaps, ensuring U.S. forces maintain credible, effective, and adaptable deterrent options.

Leveraging APL’s system-level perspective, the program provides the Navy and Air Force with technical direction, solutions and recommendations for future requirements, and selective prototyping capabilities – an integrated approach that ensures strategic deterrence systems remain reliable and effective throughout their life cycle.
