The Sukhoi Superjet 100 () or SSJ100 is a regional jet designed by Russian aircraft company Sukhoi Civil Aircraft, a division of the United Aircraft Corporation (now: Regional Aircraft – Branch of the Irkut Corporation). 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 MTOW plane typically seats 87 to 98 passengers and is powered by two PowerJet SaM146 turbofans developed by a joint venture between French Safran and Russian NPO Saturn. By May 2018, 127 were in service and by September the fleet had logged 300,000 revenue flights and 460,000 hours. By November 2021 fleet had logged at least 2,000,000 hours. The plane has recorded three hull loss accidents and 86 deaths . In 2022, Sukhoi plans a Russified version of the body and electronic, without most of the Western components, the engine will also be replaced, using Aviadvigatel PD-8. Aeroflot has ordered 89 Irkut SSJ-Russified aircraft. Development Background JSC Sukhoi was incorporated in May 2000 to develop the first all-new commercial aircraft in post-Soviet Russia. Studies of the Russian Regional Jet (RRJ) began in 2001. After analysing the Russian market, Sukhoi identified a need for an aircraft with a range of between , greater than typical regional jets. Three variants were initially envisaged: the RRJ60, RRJ75 and RRJ95, with 60, 78 and 98 seats respectively; a five-abreast layout was chosen as being optimal for this size range. Sukhoi estimated the targeted market to be around 800 aircraft, including 250–300 from Russia and the Commonwealth of Independent States. On 15 October 2001, the Russian government allocated $46.6 million to the development of a new 70–80 seat regional jet, targeting first flight in 2006 and entry into service in 2007. Sukhoi's RRJ was competing against Myasishchev's M-60-70 and Tupolev's Tu-414 projects. Boeing provided advice to Sukhoi and its partners on programme management, engineering, marketing, product development, certification, supplier management and customer support. The Sukhoi RRJ was selected by Rosaviakosmos, the government's aviation and space agency, in March 2003. The RRJ programme allocated $63.5 million to the development of a engine between 2003 and 2015. Four engines were initially envisaged: the Pratt & Whitney PW800, the Rolls-Royce BR710, the General Electric CF34-8, and the Snecma/NPO Saturn SaM146. The BR710 and the CF34-8 were eliminated by July 2002, and the PW800 was subsequently rejected due
