Science & Technology for Nuclear Re-entry Systems

The Science & Technology for Nuclear Re-entry Systems program is a significant initiative under the Department of Defense. It aims to advance technologies for nuclear re-entry systems, aligning with strategic priorities to maintain operational effectiveness and address evolving threats to nuclear forces. One of its main objectives is to develop advanced technology that reduces technical and programmatic risks associated with nuclear modernization, thereby preserving the viability of the nuclear deterrent in a cost-effective manner.

A crucial aspect of this initiative is the Nuclear Delivery Systems project. This project focuses on developing modern technologies, subsystems, and components for reentry systems. The goal is to mature these technologies to a Technology Readiness Level of 6 through relevant ground and flight test environments. This process aims to mitigate risks related to Navy reentry system modernization and ensure survivability against credible threats such as Ballistic Missile Defense Systems and Anti-Submarine Warfare on SSBN platforms.

The program emphasizes collaboration with other agencies, including STRATCOM and the Air Force, to identify and mature technologies for Reentry System components like Aeroshell, Fuzing, and Guidance. These efforts are designed to enhance flexibility and affordability, ensuring that strategic weapon systems can adapt to changes in missions or adversaries. Additionally, it addresses workforce challenges by investing in skills development necessary for supporting advanced technology development across the nuclear enterprise.

Specific initiatives within the program include Reentry Capability Demonstrations (RCD) focusing on developing Aeroshell and Fuzing technologies to support future threats. These demonstrations involve detailed technical design work, integration assessments for flight tests, and procurement of necessary hardware. Furthermore, advanced technology demonstration efforts are planned to initiate investments in technical maturation areas following concept studies and survivability assessments.
