Royal Aircraft Factory S.E.5a

The S.E.5a was a British single-seat biplane fighter built by the Royal Aircraft Factory and flown by Allied squadrons in the closing years of the First World War. Developed by a design team that included Henry Folland and John Kenworthy, it combined speed with stability and manoeuvrability rare for a fighter of its day, later earning the nickname the Spitfire of the First World War. It served alongside the Sopwith Camel as one of the most capable Allied fighters of the conflict, flown by leading aces on the Western Front.
