In May 1977, Sukhoi Su-27 made its first flight and officially entered service with the Soviet Air Force in 1985. It is a twin engine fighter plane built by the former U.S.S.R, in an attempt to out do similarly advanced American aircraft. The aircraft can reach a maximum supersonic speed of Mach 2.35 which is 1,500 mph or 2,500 km/h.
It takes up to 16.03 hours to get around the world and costs $27, 000,000.00. The "Flanker" was intended as a direct competitor for the large United States fourth generation fighters such as the Grumman F-14 Tomcat and F-15 Eagle. Although it is not a true delta, the Su-27 is also an example of a tailed delta wing configuration, retaining conventional horizontal tailplanes.
