Restricted Data is the foundational AEA category: 'all data' concerning weapon design/manufacture/use, special-nuclear-material production, or its use in energy, except what DOE has specifically declassified under Section 142. Because the definition is 'all data,' RD underpins the 'born classified' doctrine. RD is never automatically declassified and may be declassified only by DOE; it is exempt from the automatic-declassification provisions of E.O. 13526. Marked as a caveat on the level (e.g., S//RD, TS//RD).
