Declassification is the legal and administrative process by which information originally classified as restricted for national security reasons is officially changed to unclassified status, making it accessible to the public. In the United States, this process is governed primarily by Executive Order 13526 (signed December 29, 2009) and administered by the National Declassification Center within the National Archives and Records Administration. Five primary methods enable declassification: automatic review after 10, 25, or 50 years; agency-initiated review when original classification justification no longer applies; Mandatory Declassification Review (MDR) requests by the public; Freedom of Information Act (FOIA) requests; and direct Presidential declassification authority. The President holds constitutional authority to declassify any executive branch information immediately, bypassing standard review procedures. In the context of UAP/UFO archives, declassified materials represent formerly restricted government documents on these topics that have undergone formal review and been released for public research.

Desclassificação é o processo legal e administrativo pelo qual informações originalmente classificadas como restritas por razões de segurança nacional são oficialmente alteradas para o status de desclassificadas, tornando-as acessíveis ao público. Nos Estados Unidos, este processo é regido principalmente pela Ordem Executiva 13526 (assinada em 29 de dezembro de 2009) e administrado pelo National Declassification Center no National Archives and Records Administration. Cinco métodos principais permitem a desclassificação: revisão automática após 10, 25 ou 50 anos; revisão iniciada por agência quando a justificativa de classificação original deixa de ser válida; solicitações de Revisão de Desclassificação Obrigatória (MDR) pelo público; solicitações da Lei de Liberdade de Informação (FOIA); e autoridade de desclassificação presidencial direta. O Presidente detém autoridade constitucional para desclassificar qualquer informação do ramo executivo imediatamente, contornando procedimentos de revisão padrão. No contexto de arquivos de UAP/OVNI, materiais desclassificados representam documentos governamentais anteriormente restritos sobre esses tópicos que sofreram revisão formal e foram liberados para pesquisa pública.
