   An EE-17 Sucuri (sometimes referred ad the Sucuri I) tank destroyer was developed in Brazil by ENGESA. This wheeled armored vehicle had a complete turret of the French AMX-13 light tank. It packed a 105 mm gun and was fitted with an autoloader. However the EE-17 was not selected for production and this tank destroyer was completely redesigned. The result was the EE-18 Sucuri. Sometimes it is referred as the Sucuri II. It was developed in 1987. This armored vehicle had a number of automotive components of the EE-9 Cascavel armored reconnaissance vehicle. It had a turret of new design. Unfortunately ENGESA went into bankruptcy in 1993 and the EE-18 has never reached production.

   The EE-18 was designed to engage tanks, various armored vehicles, building and field fortifications. Even though its 105 mm gun would not be particularly efficient against the latest contemporary main battle tanks, though it could easily knock-out older tanks. The EE-18 could rapidly self-deploy over long distances.

   Vehicle has a welded composite armor hull and turret. The front arc provides protection from 20-25 mm projectiles. All-round protection is against small-arms fire and artillery splinters. An NBC protection system was not offered as standard.

   Turret of the EE-18 packs a fully-stabilized Italian OTO Melara 105 mm gun. This gun was compatible  with standard NATO munitions. Vehicle was fitted with modern fire control system. Its armor-piercing round can penetrate 150 mm of steel armor at a range of 5 000 meters.

   There was a coaxial 7.62 mm machine gun and a roof-mounted 12.7 mm heavy machine gun.

   Vehicle had a crew of four, including commander, gunner, driver and loader. Crew would enter and leave the vehicle through the rear doors. These doors were also used to load ammunition.

   The EE-18 Sucuri was powered by a SAAB-Scania DSI-11 diesel engine, developing 380 horsepower. It had an unusual boomerang-type rear suspension, similar to that, used on other ENGESA vehicles. Such suspension offered good cross-country performance. Vehicle was also fitted with a centralized tyre pressure system.
