The Marinens Flyvebaatfabrikk M.F.11 (or Høver M.F.11, for its designer) was a three-seat, single-engine biplane used by the Royal Norwegian Navy Air Service for maritime reconnaissance in the decade before the Second World War. The M.F.11 was the main aircraft of the Royal Norwegian Navy Air Service (RNoNAS) until the German invasion of Norway in 1940.
