History[ | ]

Class: Main Battle Tank (Prototype)
Developed: 1982-1988
Service: N/A
Vehicles Built: 5
Operators: N/A

The Osório Main Battle Tank was to be the crown jewel of the development line for a Brazilian company called Engesa. The main raison d'etre for the tank was the (correct) idea that third world nations could use something more rugged and cheaper than the expensive western equipment. Western tanks were simply too complex, heavy and pricey but something smaller, simpler and yet capable of fitting into the main battle tank category could be a success.

The development was fraught with issues but the first prototype was introduced to Saudi Arabia in 1985. It was a very conventional tank armed with the reliable Royal Ordnance 105mm L7A3 gun – for the second prototype, however, this weapon was already replaced by a GIAT 120mm smoothbore. The tank was quite customizable – various systems could be installed if the customer wished so, including a wide range of fire control systems, ballistic computers and other sophisticated devices. Despite the intensive advertising, no buyers were interested and not even the Brazilian army bought the tank. It turned out to be a massive flop.

But that was not the only element of the equation, another was the specific market dependency. Engesa was never a leader or an innovator – it always used various proven solutions and modules. Engesa's goal was to make as much money as possible from export contracts and as such it focused on building vehicles with a very good price to firepower ratio. Exports were mostly driven by South American armies needing to replace truly obsolete vehicles along with several African countries – notably Iran and Iraq. The Iran-Iraqi conflict was the driving force for effective armor demand – both sides of the conflict were desperate for affordable vehicles, while other countries in the region were buying arms preventively – just in case the conflict spilled over into the "neighborhood". Everything changed in 1991.

The Gulf War meant two things: the loss of the Iraqi market due to the American embargo and the loss of other markets in the region due to the alliance of several countries with the United States. It was also at this time that the market became flooded with the obsolete NATO and Warsaw Pact equipment and at that point even relatively modern vehicles were often available for their price in scrap. Engesa invested over 100 million USD into the Osório development and all that money was lost to the company. This combination of factors dragged the company into serious financial trouble that ended with bankruptcy in 1993.

This MBT's front is protected by composite armor. Composite armor consists of combined layers of steel and other material and offers excellent protection against HEAT shells and ATGMs. Its steel turret, sides and rear are considerably more vulnerable.
