L-29 series was produced in 1963 and 1973, all built 3665 machines. The most massive in the world of jet training aircraft “Dolphin” was in service with 19 countries (USSR, Czechoslovakia, Afghanistan, Bulgaria, Vente, Vietnam, GDR, Ghana, Guinea, Egypt, Indonesia, Iraq, Yemen, China, Mali, Nigeria, Romania, Syria, Uganda).
