Su-34 fighter bomber (Russian: C ü - 34, English: Su-34, NATO code name: fullback, Chinese: guard, nickname: platypus, commonly known as Sukhoi Su-34), is a Soviet / Russian type I high mobility, all-weather, supersonic, two engine, two seat fighter bomber. [1] Su-34 fighter bomber inherits the excellent aerodynamic shape design of Su-27 fighter family, and its biggest feature is its flat head. The reason is that it adopts the design of parallel double seat, which makes its head larger. At the same time, in order to reduce the volume, it designs its head flat, and uses many advanced equipment, such as new fire control computer, liquid crystal display, new data link and rear view Radar, etc. The Su-34 fighter bomber was developed by Sukhoi Design Bureau of the Soviet Union (or Sukhoi, now Sukhoi company of the Russian joint aircraft manufacturing group). The earliest model is the su-27ib test aircraft. The test aircraft first flew in April 1990, and the pre production aircraft first flew on December 18, 1993. Originally, it was expected to be fully installed in 2002, but due to the lack of funds caused by the collapse of the Soviet Union, the Russian Ministry of defense did not announce the formal acceptance until July 2007.
