Sukhoi Superjet 100: Regional Jet Innovation Explained

Introduction

The Sukhoi Superjet 100 (SSJ100) is a regional jet developed by the Russian aircraft manufacturer Sukhoi Civil Aircraft, a division of the United Aircraft Corporation (UAC). As a key player in Russia’s civil aviation industry, the SSJ100 was designed to compete with Western regional jets like the Embraer E-Jet series and Bombardier CRJ series. Launched in 2000, the aircraft made its maiden flight in 2008 and entered commercial service in 2011. The SSJ100 was intended to modernize Russia’s aviation sector, replacing aging Soviet-era aircraft such as the Tupolev Tu-134 and Yakovlev Yak-42.

With a seating capacity of around 98 passengers and a range of up to 4,578 kilometers (2,472 nautical miles), the SSJ100 is primarily used for short to medium-haul flights. It has been sold mainly to Russian airlines but has also seen limited adoption outside Russia. The aircraft’s development involved collaboration with several Western companies, including Boeing, which provided consulting services, and Safran, which co-developed the jet’s engines through a joint venture with Russia’s NPO Saturn.

This article delves into the Sukhoi Superjet 100’s development history, technical specifications, operational performance, and future prospects.


Development History

The development of the Sukhoi Superjet 100 began in the early 2000s as part of Russia’s efforts to revitalize its civil aviation sector. The project was initially known as the Russian Regional Jet (RRJ) program, with plans for three variants: RRJ-60, RRJ-75, and RRJ-95. However, in 2005, Sukhoi decided to focus on the higher-capacity RRJ-95 model due to its greater market potential. The aircraft was later rebranded as the Sukhoi Superjet 100.
