context_page_description: The Aero A.300 was a Czechoslovak bomber aircraft that first flew in 1938 as a much refined development of the A.304.
  Designed by Aero as a replacement for the obsolete, locally-built Bloch MB.200 bombers Czechoslovak Air Force, the Aero A-304 transport/bomber formed the basis for its design. The new aircraft mounted Bristol Mercury IX radial engines rated at 610 kW/820 hp and carried three machine guns for defense. The A-300 was faster than any other Czechoslovakian aircraft in the inventory except for the Avia B-35 fighter. Despite showing much promise, development and production of the aircraft was interrupted by the outbreak of World War II.
