The Russian Knights (, Russkiye Vityazi) is an aerobatic demonstration team of the Russian Air Force. Originally formed on April 5, 1991 at the Kubinka Air Base as a team of six Sukhoi Su-27s, the team was the first to perform outside the Soviet Union in September 1991 when they toured the United Kingdom. On December 12, 1995, disaster struck as three team jets flew in-formation into a mountainside near Cam Ranh, Vietnam during approach while en route to home from a Malaysian airshow during adverse weather conditions. The team now performs with four Su-27Ps and two Su-27UBs.
