Based on Aermacchi's proven MB.326 design, in 1970 Embraer acquired licence rights to build the AT-26 in Brazil to supersede the T-33 in the training role and also to provide offensive capability. They eventually produced a total of 182 EMB-326s - 167 for the FAB, nine for Paraguay and six for Togo. The Xavante name was in honour of the pre-Columbian native Brazilian warrior tribe. Interestingly two other AT-26s are preserved in Brazil, falsely marked as 4462.
