Program detail

Mission & acquisition strategy

This program funds activities at the Cyber Resiliency Office for Weapon Systems (CROWS). The CROWS is the sole organization tasked to enhance and enable Department of the Air Force (DAF) Program Acquisition Executives (PAEs) and Program Management Offices (PMOs) to understand, engineer, and integrate cyber resiliency into emerging and fielded weapon systems, to mitigate critical cyber-based vulnerabilities, and preserve mission effectiveness in contested environments. The CROWS' mission directly aligns with the National Defense Strategy (NDS). The NDS specifically emphasizes deterring and defending against cyber threats as vital to safeguarding the U.S.

When possible, activities in this effort will leverage current competitively-awarded contracts. Additional necessary contracts funded in this program element will be awarded using either competitive or sole source procedures, whichever is most appropriate. The government agency responsible for managing the program is the Air Force Life Cycle Management Center, Cyber Resiliency Office for Weapon Systems, Wright-Patterson Air Force Base, Ohio and Hanscom Air Force Base, Massachusetts.

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix.

Project detail

What project 642812 buys

The Acquisition/System Security Engineering (SSE) activity encompasses several continuous efforts to support the Department of the Air Force (DAF) and Department of War acquisition community. First, it produces and distributes standard system security engineering and acquisition security processes, policies, and contracting language to ensure cyber requirements are properly addressed in fielded and emerging weapon systems. Second, it bolsters intelligence collection and intelligence community engagement to provide consistent and current knowledge of cyber threats to enable the acquisition community to calculate weapon system risks. Third, it develops and hones personnel cyber resiliency training, manning strategies, and integrates Cyber Focus Teams into Program Acquisition Executive (PAE) Offices to bridge the lack of cyber acquisition expertise. Fourth, it explores and evaluates the DAF's dynamic cyber landscape to uncover vulnerabilities and prioritize cyber techniques, products, and technologies for further development and prototyping to counter evolving threats. Fifth, it resources a DAF-unique cyber engineering benchtop facility exploring, assessing, and mitigating navigation, communication, and electronic warfare vulnerabilities. Sixth, it develops software to enable digital engineering transformation of risk identification and tracking for weapon systems. Seventh, it enables the Cyber Resiliency Office for Weapon Systems (CROWS) to research, publish, and deliver government-owned guidance, roadmaps, and references to enable program offices and industry partners to effectively implement and adapt DAF strategic cyber requirements (example: Zero Trust and Defensive Cyber Operations) to weapon systems. The centralized and consolidated nature of the CROWS saves the acquisition community millions annually by eliminating the need for each weapon system program and industry partner to fund individual cyber technical exploration efforts. Eighth, the Mitigations activity enables the Cyber Resiliency Office for Weapon Systems (CROWS) to be the DAF's focal point for enterprise cyber mitigations to critical cyber vulnerabilities for fielded weapon systems, subsystems, and support systems.

FY2027 planned work - Transitioning work under project 642812, Acquisition/System Security Engineering, and continue to research, develop, prototype, and demonstrate transition-ready mitigations on fielded weapon systems, subsystems, and support systems in realistic, high-fidelity environments to known cyber vulnerabilities aligned with program office plan of action and milestones (POA&Ms) and DAF cyber vulnerability/mitigation data calls.

FY2026 to FY2027 change FY 2027 decreased compared to FY 2026 by $5.982 million due to transitioning work to project 642812 which better informs program office weapon system acquisition decisions with mitigation development needs.

FY2026 plans — current year - Continue to research, develop, prototype, and demonstrate transition-ready mitigations on fielded weapon systems, subsystems, and support systems in realistic, high-fidelity environments to known cyber vulnerabilities aligned with program office plan of action and milestones (POA&Ms) and DAF cyber vulnerability/mitigation data calls.

Project detail

What project 642834 buys

The Mitigations activity encompasses continuous efforts to support the Department of the Air Force (DAF) and Department of War acquisition community. It enables the Cyber Resiliency Office for Weapon Systems (CROWS) to be the DAF's focal point for enterprise cyber mitigations to critical cyber vulnerabilities for fielded weapon systems, subsystems, and support systems. In FY 2027, the entirety of project 642834, Mitigations, was transferred to project 642812, Acquisitions/System Security Engineering. This is an administrative realignment to better highlight the synergy between the two activities and does not represent an increase or decrease in priority relative to the overall program. This program element included all necessary expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605829F, 0605831F, 0605833F, and 0605898F.

Project detail

What project 642836 buys

The Mission Risk Analysis project encompasses one continuous effort to support the Department of the Air Force (DAF) and Department of War acquisition community. It enables the Cyber Resiliency Office for Weapon Systems (CROWS) to be the sole-organization to collect and analyze weapon system data from multiple sources (ex. Program Executive Office portfolios and test and evaluation efforts) to understand the DAF's cyber vulnerability landscape and mitigation initiatives to inform senior leader resource investment strategies. Additionally, this effort informs efforts in the other CROWS projects to prioritize research and investments to solve enterprise cyber vulnerability and mitigation needs. This program element included all necessary expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605829F, 0605831F, 0605833F, and 0605898F.
