{"abstract":"In accordance with the Privacy Act of 1974, the Department of the Navy is modifying and reissuing a current system of records titled, \"Millennium Cohort Study, N06500-1. This system of records was originally established to collect and maintain records on service members and veterans who have, or have not, deployed overseas so that various longitudinal health and research studies may be conducted over a 67-year period. This system of records notice (SORN) is being updated to change the system name and system ID, expand the \"Purpose\" section, and to incorporate the DoD standard routine uses and support additional information sharing of these records outside of the Department. The Navy is also modifying various other sections within the SORN to improve clarity or update information that has changed.","action":"Notice of a modified system of records.","agencies":[{"raw_name":"DEPARTMENT OF DEFENSE","name":"Defense Department","id":103,"url":"https://www.federalregister.gov/agencies/defense-department","json_url":"https://www.federalregister.gov/api/v1/agencies/103","parent_id":null,"slug":"defense-department"},{"raw_name":"Department of the Navy","name":"Navy Department","id":378,"url":"https://www.federalregister.gov/agencies/navy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/378","parent_id":103,"slug":"navy-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/04/30/2026-08431.html","cfr_references":[],"citation":"91 FR 23249","comment_url":"http://www.regulations.gov/commenton/USN-2026-HQ-0265-0001","comments_close_on":"2026-06-01","correction_of":null,"corrections":[],"dates":"This system of records is effective upon publication; however, comments on the Routine Uses will be accepted on or before June 1, 2026.
