The Henschel Hs123 was a single-seat biplane dive bomber and close-support attack aircraft flown by the German Luftwaffe during the Spanish Civil War and the early years of World War II.

The Gloster Gauntlet was a British single-seat biplane fighter of the RAF, designed and built by the Gloster Aircraft Company in the 1930s. It was the last RAF fighter to have an open cockpit and its penultimate biplane fighter in service. It was also Britain's most successful and popular inter-war fighter aircraft.

The Blackburn Shark torpedo/spotter/reconnaissance biplane was overshadowed by its competitor the Fairey Swordfish. In reality though, the Shark was more modern than the Swordfish and performed better, and had it not been bedevilled with engine trouble in its early service, might have gone on to great things.
