SSBN Security Technology Program

The SSBN Security Tech Program is a Navy research, development, test, and evaluation (RDT&E) initiative, funded under Program Element (PE) 0101224N, with the primary objective of advancing the security and survivability of the United States' ballistic missile submarines (SSBNs) and related undersea assets. This program is a critical component of the Navy's efforts to ensure the effectiveness and resilience of the sea-based leg of the nuclear triad. The program is structured to address emerging threats to SSBNs and to maintain their ability to operate undetected in increasingly contested maritime environments.

The largest line item within this program element is focused on research and development activities that enhance the stealth, survivability, and operational effectiveness of SSBN platforms. This includes the development and integration of advanced technologies to counter adversary anti-submarine warfare (ASW) capabilities, improve acoustic and non-acoustic signature management, and support mission assurance for strategic deterrence patrols. The program is managed by the Navy and supports both current and future classes of SSBNs.

A smaller but significant component is dedicated to research and development efforts aimed at protecting critical undersea infrastructure and enhancing the Navy's ability to detect, deter, and defeat threats in the subsea and seabed domains. The objectives include developing technologies and operational concepts to secure undersea cables, sensors, and other vital assets against sabotage or interference. This program supports broader Department of Defense (DoD) and national security goals by ensuring the integrity and resilience of undersea infrastructure that is essential for military operations, communications, and economic stability.

Another line of effort focuses on the survivability of attack submarines (SSNs) and guided missile submarines (SSGNs). The objectives include advancing RDT&E activities to improve the ability of these platforms to evade detection, counter emerging threats, and operate effectively in contested environments. This may involve the development of new countermeasures, improvements in submarine design, and enhancements to onboard systems that support stealth and survivability. The survivability program is essential for maintaining the operational relevance of the Navy's attack and guided missile submarine fleets in the face of evolving adversary capabilities.

The justification for the SSBN Security Tech Program is rooted in the need to maintain a credible and survivable sea-based nuclear deterrent, as well as to protect critical undersea assets and infrastructure. As potential adversaries invest in advanced ASW technologies and undersea warfare capabilities, the Navy must continue to innovate and adapt to ensure the strategic advantage of its submarine forces. The program's investments in research, development, and technology integration are designed to address both current and anticipated threats, supporting the long-term effectiveness of U.S. undersea operations.

Due to the classified nature of the detailed technical objectives and accomplishments, specific programmatic information is submitted to Congress in classified budget justification books. The unclassified summary indicates that the program is focused on operational systems development, with an emphasis on technology maturation, risk reduction, and the transition of advanced capabilities to the fleet. The program does not procure RDT&E articles directly but instead supports the development and demonstration of technologies that can be integrated into operational platforms.
