The designation “USS Dash (AM‑428)” does not appear in widely recognized naval reference works, official United States Navy ship registries, or major historical databases. No verifiable records confirm the existence of a United States Navy vessel named Dash carrying the hull classification symbol AM‑428, which would denote an auxiliary minesweeper.
It is possible that the term results from a typographical error or a conflation with other ships bearing the name Dash. The United States Navy commissioned USS Dash (AM‑88), an Admirable‑class minesweeper launched in 1942 and later transferred to the Soviet Navy, but no credible source links the name Dash to the hull number 428.
Without corroborated documentation—such as commissioning orders, shipyard construction records, or inclusion in authoritative naval listings—accurate details about a vessel identified as USS Dash (AM‑428) cannot be provided. Consequently, the term lacks sufficient encyclopedic information for a standard factual entry.
