Not announced in the January 29, 2026 release; no public source names a chair or leader for STIB as of that announcement.
STIB is described as consolidating DIB and DSB advisory roles to provide science, technology and innovation advice to senior leaders; it aims to streamline input, eliminate overlap, and accelerate technology delivery—but the release does not list new statutory authorities beyond those longstanding advisory functions.
The merger was approved Jan. 29, 2026 and is "pending formal establishment by the Federal Register"; no detailed transition timeline or effective date was published in the announcement.
The January 29 release does not say current DIB/DSB members will automatically become STIB members; membership/appointments are typically set by charter and Federal Register notices—no such roster transfer was announced.
The announcement says STIB will streamline and unify advisory input across science and innovation; interactions with other defense advisory bodies and civilian agencies are not detailed in the release and would be governed by STIB’s charter and interagency procedures once established.
The War Department is the department making the change; its relationship to the broader U.S. national security structure (analogous to the Department of Defense) is unchanged by creating STIB—the action reorganizes internal advisory boards, not the Department’s place in government.
