The designation “USS Rich (DD‑820)” does not correspond to a widely documented United States Navy ship. No reliable naval records, official ship registries, or reputable historical sources identify a destroyer with the hull number DD‑820 bearing the name Rich.
The name Rich has been assigned to a United States Navy vessel, specifically USS Rich (DE‑695), a Buckley‑class destroyer escort commissioned in 1944 and lost later that year during the Normandy invasion. No comparable entry exists for a Gearing‑class (or any other class) destroyer designated DD‑820.
Given the absence of verifiable information, the term appears to be a misidentification or typographical error rather than an established naval designation. Consequently, no encyclopedic entry can be provided beyond this clarification.
