In 2022, Embraer and NAC announced their intent to develop a cargo conversion program based on the E1 airframe. The announcement came with an order for 10 E190Fs.
The announcement was followed by news from NAC that it had a deal with Kenya-based Astral Aviation for two freighters. Regional One was another potential customer that drew attention.
The conversion program was driven by two key concepts: a potential supply base of over 1,500 aircraft and the need for a smaller freighter optimized for e-commerce. The idea had merit then and still does.
