HISTORY: The MB-326K is the most successful single seat development of a two seat jet trainer, and has provided a number of third world nations with an effective light attack capability.
Right from the beginning of the MB-326 jet trainer program, its designer Dr-lng Ermano Bazzochi intended that the aircraft also be an effective light strike platform, and this capability no doubt influenced a number of the two seat MB-326's customers to order it. The two seater proved to be a stable and effective weapons platform and a single seater optimised for light attack became a logical development.
The single seat MB-326K was developed well into the 326's career, given that the prototype two seater flew in 1957 and the single seat prototype flew on August 22 in 1970. The K was based on the MB-326G, which compared to earlier Macchis featured a strengthened airframe and more powerful Viper 20 engine. The first K prototype featured the 15.2kN (341 Olb) Viper 20, while the second had the more powerful 18.8kN (4000lb) Viper Mk 632-43 intended for production aircraft which allowed an increased armament capability compared with two seaters and the fitting of two internal 30mm DEFA cannon. The second seat meanwhile gave way to avionics and fuel.
Despite a 1970 first flight, because of a lack of orders the first production machines were not built until 1974. The first customer was Dubai, which eventually took delivery of six MB-326KDS, while others were delivered to Zaire (MB-326KB), Ghana (MB-326KG) and Tunisia (MB-326KT).
South Africa was the MB-326Ks largest customer, taking delivery of seven Italian built MB-326KMs and 73 Atlas licence assembled 15.1kN (3360lb) Viper 540 powered Impala 2s.
