The US Senate Committee on Armed Services convened on September 11, 2025, to consider the nomination of General Christopher J. Mahoney, USMC, for reappointment to the grade of general and to serve as Vice Chairman of the Joint Chiefs of Staff. A significant focus of the hearing was on the role of cyber security and resiliency in national defense.

During the discussions, a senator highlighted the importance of cyber capabilities in developing the national military strategy. The senator emphasized that cyber should be viewed not only as a separate domain but also as a critical enabler for joint operations across traditional domains such as land, sea, air, and space. In response, General Mahoney acknowledged his limited expertise in cyber matters but recognized the need to integrate cyber considerations into military strategy.

The conversation underscored the growing recognition of cyber security as an essential component of modern warfare and national defense. As the hearing progressed, it became clear that the integration of cyber capabilities into military operations will be a key focus for General Mahoney if confirmed.

The committee's deliberations reflect the increasing importance of cyber resilience in the face of evolving threats, signaling a shift in how military strategy will address the complexities of modern warfare. The outcome of this nomination will have implications for the future direction of the US military's approach to cyber security.
