Earliest documented public appearance: published YAH-64 designation
Earliest supported public appearance found in the sources reviewed for this research; not a claim of the first-ever announcement or original unveiling. Earlier evidence may revise this date. Army Aviation’s August 1973 issue lists the Hughes YAH-64 among recently announced DOD designations. The date refers to the publication, not the undated earlier DOD announcement.
