The Yakovlev SJ-100 (until August 2023: Sukhoi Superjet 100 [SSJ100], Russian: Сухой Суперджет 100, romanized: Sukhoy Superdzhet 100) is a regional jet originally designed by the now-merged Russian aircraft company Sukhoi Civil Aircraft, a division of the United Aircraft Corporation (now: "Regional Aircraft" company branch). With development starting in 2000, it made its maiden flight on 19 May 2008 and its first commercial flight on 21 April 2011 with Armavia.
The 46–49 t (45–48 long tons) MTOW plane typically seats 87 to 98 passengers. Aircraft built before 2025 are powered by two 77–79 kN (17,000–18,000 lbf) PowerJet SaM146 turbofans developed by a joint venture between French Safran and Russian NPO Saturn. By May 2018, 127 aircraft were in service, and by September the fleet had logged 300,000 revenue flights and 460,000 hours. By November 2021 the fleet had logged at least 2 million hours. The type has recorded five hull loss accidents and 89 deaths as of January 2026.
