The Embraer E-Jet family is a series of four-abreast, narrow-body, short- to medium-range, twin-engined jet airliners designed and produced by Brazilian aerospace manufacturer Embraer.
The E-Jet was designed as a complement to the preceding ERJ family, Embraer's first jet-powered regional jet. Designed to carry between 66 and 124 passengers, it was larger than any prior aircraft built by the company. The project's existence was revealed in early 1997 and was formally introduced at the Paris Air Show two years later. On 19 February 2002, the first prototype E-Jet conducted its maiden flight; later that year, quantity production of the type commenced. In early March 2004, the first E170 deliveries were made to LOT Polish Airlines. Larger versions of the aircraft, the E190 and E195, debuted later in 2004, while a slightly stretched version of the E170 was introduced in mid-2005 as the E175.
The E-Jet series has been a commercial success primarily due to its ability to efficiently serve lower-demand routes while offering many of the same amenities and features of larger jets. Initial teething issues were quickly overcome and Embraer rapidly expanded product support for better global coverage. The E-Jet family is commonly used by both mainline and regional airlines around the world and has become particularly popular with regional airlines in the United States. It has also served as the basis for the Embraer Lineage 1000 business jet. During the 2010s, Embraer developed a second generation, the E-Jet E2 family, with more fuel-efficient engines. However, as of 2023, the first generation E175 remains in production, to fulfill demand from regional airlines in the United States, which cannot use the newer generation due to scope clause restrictions.
