EE-T2 Osório
By the mid-1980s, Engesa had spent US$100 million on the development of the Osório, a main battle tank, but was unable to find a buyer for it. This design of the Brazilian armaments industry was sophisticated, and demanded a high investment in technology. It was equipped with computers and endowed with a modern system of weapons. The improved version would have receive the designation of EE-T1 (armed with a 120mm cannon), and the version that would have been adopted for the Brazilian Army (armed with a 105mm cannon) the EE-T2 Osório [but this was never really defined].
The original model was provided for real tests in Saudi Arabia, it was the winner of the competition between M-1 Abrams, 40 AMX and Challenger, in the late 1980s. The Osório project came to an abrupt end with Operation Desert Storm against Iraq in 1991. In 1990 Engesa had won the evaluation process by the Saudis. After Desert Storm, Brazil was no match for United States competition, given the close ties that developed between Saudi Arabia and the United States during the war with Iraq.
