The Sukhoi 
      company has produced some of the most advanced Soviet jet fighters of all 
      time. About half of Russia's current tactical air power is due to Sukhoi's 
      contributions.
      The history 
      of the Sukhoi company is closely associated with the life of Pavel Sukhoi, 
      one of the greatest Soviet aircraft designers. Sukhoi, born in 1910, had a 
      very uneven career characterized by two distinct phases. If, in the first 
      part of his career, he was dogged by bad luck, he flourished enormously in 
      his later days.
      Like many of 
      his contemporaries such as Sergey Korolev, chief designer of the Soviet 
      space program, Sukhoi served his apprenticeship under the famous Andrey 
      Tupolev, the patriarch of the modern Soviet aviation industry. In the 
      1920s and 1930s, as a senior engineer working for Tupolev at TsAGI (the 
      Central Aero-hydrodynamics Institute), the premiere Soviet aeronautics 
      organization, Sukhoi designed several bombers and fighters. He also worked 
      on a number of Tupolev designs including the ANT-31 (I-14), which was the 
      first Soviet all-metal low-wing monoplane fighter with retractable 
      undercarriage and an enclosed cockpit. His first truly independent design 
      was the ANT-51 (Su-2), a ground-attack aircraft that entered service in 
      1940.
      In September 
      1939, the Soviet government appointed Sukhoi to head a new organization 
      named the Experimental Design Bureau No. 134 (OKB-134) at a plant in the 
      city of Kharkov in Ukraine. (The Russians called their aeronautics 
      companies "design bureaus.") There, he designed the Su-6 ground-attack 
      aircraft. Although he produced several excellent designs during the 1930s 
      and 1940s, he was never able to achieve success due to a combination of 
      testing accidents, political opposition, and Stalin's personal whims. 
      After the war, Stalin assigned him and several other major Soviet 
      designers—such as Mikoyan, Lavochkin, and Yakovlev —to build the first 
      generation of Soviet jet fighters. Sukhoi used the German Me 262 and 
      modified it to build his own Su-9 fighter. The Soviet Air Force never used 
      the aircraft, partly because Stalin criticized Sukhoi for simply copying 
      an old German aircraft instead of proposing an original Russian design. 
      Ironically, it was at the very same time that Stalin had ordered Tupolev 
      to make an exact copy of the American B-29 Superfortress.
      Despite the 
      setback, Sukhoi doggedly continued to pursue more advanced designs 
      including the supersonic Su-17, a prototype for a frontline fighter. 
      Eventually, Stalin grew intolerant of Sukhoi's work and closed down 
      OKB-134 in November 1949; Sukhoi's team ended up as a subdivision of the 
      Tupolev design organization.
      Sukhoi's 
      second—and far more successful—career began after Stalin's death in 1953. 
      Later that year, in October, Stalin's successors put Sukhoi to work at a 
      plant in Moscow where he formed a new organization known as OKB-51. The 
      current Sukhoi company grew from this organization.
      The design 
      bureau designed and built a series of new supersonic jet fighters 
      including the Su-7 and Su-9 in the 1950s and 1960s. These two aircraft 
      were extensively modified over the years and used in vast numbers by the 
      Soviet Air Force and other Communist countries. Like a number of other 
      aviation designers, Sukhoi embraced the concept of evolutionary 
      development rather than large technological leaps in aircraft design. For 
      example, Sukhoi improved the original Su-9 delta-winged series into the 
      Su-11 and Su-15 fighter-interceptor series for service with the Soviet Air 
      Defence Forces. He also modified the Su-7B ground-attack aircraft into the 
      Su-17 variable-geometry aircraft by introducing small modifications to the 
      original design. Sukhoi's aircraft symbolized the general trend of Soviet 
      aircraft design that used common components and standardization that 
      allowed Soviet plants to produce large numbers of aircraft very quickly.
      At the same 
      time, Sukhoi did try to experiment with some radical innovations. One of 
      his most famous creations was the T-4, a highly advanced supersonic (Mach 
      3) strike/reconnaissance aircraft, proposed as a response to the American 
      B-70 Blackbird. In designing the aircraft, Sukhoi pioneered the use of new 
      compact avionics systems and titanium structures. Although the aircraft 
      flew successfully several times beginning in 1972, the Soviet Air Force 
      never used it due to shifting requirements and its high expense. A 
      full-scale model now remains in an aviation museum outside of Moscow, a 
      sad reminder of a forgotten era.
      Besides the 
      T-4, the design bureau also produced the high-performance Su-24 (codenamed 
      "Fencer" by NATO) multi-role aircraft in the 1970s, and the Su-25 ("Frogfoot") 
      close support aircraft in the 1980s. In the mid-1990s, the new Su-34 began 
      replacing the Su-24 while the redesigned Su-39 shturmovik (Russian 
      word for "battleplane" or fighter) has been substituting for older model 
      fighters such as the Su-25. Perhaps the most well known of Sukhoi's 
      fighters has been the Su-27 ("Flanker"), a long-range superiority fighter, 
      famous for its versatility and overall capabilities.
      Like all 
      Russian aviation companies, Sukhoi has been hard hit by the ruin of the 
      post-Communist economy. Despite the poor conditions, Sukhoi has recently 
      produced the new multi-role, all-weather S-37 interceptor—first flown in 
      September 1997—which is equipped with state-of-the-art electronics, 
      forward-swept wings, and thrust vector control. With the S-37, Sukhoi is 
      competing with the MiG company to provide Russia's fifth generation 
      advanced fighter aircraft. The Russian military, however, has expressed 
      little interest in the proposal. Sukhoi is also developing, again in 
      competition with the MiG firm, the lightweight Su-54 fighter, an aircraft 
      comparable to the U.S. Joint Strike Fighter.
      The Sukhoi 
      company is now known simply as OKB Sukhoi and comprises 51 percent part of 
      the AVPK Sukhoi (the Sukhoi Aviation Military-Industrial Complex), a giant 
      conglomerate of design bureaus and production plants designed to bring 
      together research, development, and production of military aircraft. It is 
      currently diversifying into the civilian market by creating sports 
      aircraft, freight vehicles, and passenger aircraft. Through its nearly 
      50-year history, the design bureau has designed about a hundred different 
      aircraft, 50 types of which were put into series production.
