The ERJ 145 is a family of regional jets produced by Embraer, a Brazilian aerospace company. Family members include the ERJ 135, ERJ 140, and ERJ 145, as well as the Legacy business jet and the R-99 family of military aircraft. The ERJ 145 is the largest of the group. Each jet in the series is powered by two turbofan engines. The family's primary competition comes from the Canadair regional jets.

Each jet in the series is powered by two turbofan engines. The family's primary competition comes from the Canadair regional jets.
The ERJ 145 was launched at the Paris Airshow in 1989 as a stretched and turbofan-powered modification of the EMB 120 Brasilia. Key components of this design included:
By 1990, Embraer engineers found that results from wind-tunnel testing were less than satisfactory, and began considering a significantly different design from the EMB 120. The proposed modified design included a slightly (22.3°) swept wing with winglets, as well as engines mounted in underwing nacelles. This second design showed markedly better aerodynamic performance, but the combination of swept wings and wing-mounted...
