text: # Dewoitine D.27
  
  The Dewoitine D.27 was a parasol monoplane fighter aircraft designed by Émile Dewoitine in 1928.
  
  ## Design and development
  
  After the end of World War I, the slump in demand for aircraft forced Dewoitine to close his company and move to Switzerland in 1927.
  
  He produced the D.27 the following year, 66 of which were produced for the Swiss Air Force from 1931. It was also license-built in Yugoslavia by Zmaj aircraft and in Romania.
  
  ## Operational history
  
  Seven strengthened versions, designated the D.53, served experimentally with the French Escadrille 7C1, flying from the aircraft carrier Béarn.
