The Universal was designed in 1963 as a new primary trainer for the FAB to replace the T-6 Texan and Fokker S-11/S-12. This is the prototype, at one time registered PP-ZTW and first flown on 29 April 1966. An initial order for 150 T-25s was increased in 1978 by an additional 28. A further development designated the YT-25B Universal II flew in 1978 but was not put into production. The T-25 was also used for counter-insurgency work and although replaced by the Tucano in both the advanced training and attack roles, it is still used as a primary and basic trainer.
