HISTORY: As the MB-326 was Aermacchi's most successful postwar design, an upgraded successor was a logical development.
The main change to the airframe was that the forward fuselage was reprofiled to feature stepped tandem cockpits (giving the instructor, who normally sits in the rear seat, greatly improved forward vision). Aermacchi also considered a number of new powerplant options, including turbofans and twins, but settled upon the familiar Viper turbojet for its performance, ease of maintenance and lower acquisition cost, despite higher fuel consumption.
The first of two prototypes flew on August 12 1976, since which time the basic aircraft has been developed into a small number of models. The base MB-339A has accounted for almost all sales and 101 were delivered to the Italian Air Force (some as MB-339PANS fitted with smoke generators for the Italian Air Force's Frecce Tricolori aerobatic team). The MB-339C meanwhile is optimised for lead-in fighter and light attack duties with advanced nav and attack systems, ability to carry missiles, a more powerful engine, lengthened nose and larger tip tanks. So far New Zealand is the only C customer.
Lockheed offered a development as the T-Bird II to meet the US's JPATS requirement, while the Italian Air Force MB-339CD (Viper 632) and export MB-339FD (Viper 680) feature a digital cockpit.
A single seat MB-339K Veltro 2 was built in prototype form only.
