"The National Security Study's Senior Advisory Board has been renamed the U.S. Commission on National Security/21st Century (USCNS/21). Originally chartered by the Secretary of Defense and supported by both the White House and the Congress, the Board has been renamed to better reflect both the scope and significance of its tasking. The USCNS/21 remains responsible for the most comprehensive review of American security since the National Security Act of 1947 was signed into law over 50 years ago. The Commission will deliver a security strategy and implementation plan designed to meet the emerging challenges of the 21st century. The USCNS/21 continues to operate as a Federal advisory committee in accordance with the Federal Advisory Committee Act (Public Law 92-463). The Study Group, chartered by the Secretary of Defense in July 1998 to conduct the study effort, will continue to be known as the National Security Study Group."
