Tanks EE-T1 and EE-T2 "Osorio" (Brazil)

20



Despite the fact that история tank building in Brazil does not have such deep roots and all experience in this area previously boiled down, as a rule, to attempts to modernize obsolete weapons in service with their own army tanks foreign production, as well as design work on the creation and further manufacture of wheeled armored vehicles, in the early 80s, engineers at Anges decided to take on the ambitious and extremely difficult task of developing the first Brazilian modern tank. In order to slightly simplify the task, and at the same time provide a fairly high level of performance of the latest machine, its design provided for the use of a number of ready-made, already well-developed units and assemblies, namely: turrets with weapons from the British experimental Valiant tank created by Vickers ”, West German automatic transmission and engine. At the same time, the engineers had plans to create two versions of the tank at once: the first, simpler, for providing their own ground forces, the second, more difficult, for export deliveries.

The first prototypes of these two variants were created in 1984 and 1985 respectively. and received the symbol EE-T1 and EE-T2. As it should be, the tanks got their own name - "Osorio" - in honor of the Brazilian national hero, a general who lived in the XIX century. Both tanks were field tested in Saudi Arabia, which indicates an orientation toward the solvent market in the Middle and Near East. After their graduation in 1986g. The mass production of the new medium tank EE-T1 "Osorio", which was mainly intended for export, began. It was planned to release 1200 machines, but of this number, all 150 were intended specifically for the Brazilian army.

The tank EE-T1 "Osorio" traditional layout. The tower and the body have spaced booking, the main frontal parts are made of multi-layered armor according to the English Chobham type. The crew, which is located in the tower, consists of three people: the commander, gunner and loader.



The main armament of the tank is the English 105-mm rifled gun L7A3, as well as the twin machine gun 7,62-mm. As an additional weapon, an 12,7-mm anti-aircraft machine gun was installed in front of the loader's hatch. Ammunition of the tank is 45 shots and 5 thousands of rounds (caliber 7,62 mm). The gun is stabilized in the 2-x hover planes, all drives are electric. As an additional protection, special six-barreled smoke grenade launchers were mounted along the sides of the rear housing of the turret. The sides of the hull, as well as the elements of the undercarriage are protected by armored screens that provide additional protection directly from cumulative ammunition.

The engine compartment of the EE-T1 "Osorio" combat vehicle is located in the rear part of the main hull. It includes West German ZF LSG 3000 automatic transmission and 12-cylinder diesel engine MWM TBD 234, made in one block, which allows replacement in field conditions in 30 minutes.

The chassis of the EE-T1 "Osorio" includes six supporting rollers per side and three supporting rollers, guides and driving wheels. Tracks were used from the West German tank "Leopard-2". On the first, second and sixth support roller are spring shock absorbers. Suspension suspension hydropneumatic.

Tanks EE-T1 and EE-T2 "Osorio" (Brazil)


Tank EE-T2 "Osorio" differs from its predecessor, first of all, by the main armament - 120-mm smooth-bore cannon S.1, created by specialists of the French state association JIAT. The fire monitoring and control system includes a panoramic sight of the crew commander VS 580-10 and a periscope sight for the gunner VS 580-19, made by the French company SPFIM. The sights are made with embedded laser rangefinders, which are connected to an electronic ballistic computer. In addition, a panoramic thermal sight with night-vision function UA-9090 from Philips was installed in the turret of the tank, which transmits an image of the terrain to screens placed in front of the commander and the gunner.

    Uh, excuse me ... a rifled gun? - From the very beginning, a flawed tank.
    Well, a tall silhouette does not cause any positive emotions.

      I would not say that the L7 is a flawed weapon. The classic way. Spent gun on the first option. The Americans in the first Abrams used the same (L7 variant). The Germans on Leopard1, too.

        The keyword is "used".
        Or do you have doubts about the superiority of smoothbore guns for tanks over rifled? Want to talk about it? - the adventure has a big topic with blackjack and its army tankers - a lot of room for conversation.

        Avenger711, if you are not a balabol - give options for promising rifled tanks .. or you will be publicly called a clown.

          The rifled cannon is now only on the Challengers, but our refusal to do it is actually caused by the launch of missiles through the barrel.
          There is also the exact opposite opinion that the smooth-bore is just UG, the accuracy is not the same. So the question is open.

            And in general, promising tanks? There are not many of them. Brazil now has no opponents armed with promising tanks. Latin America is saturated with surpluses of old state models with surplus armies. The L7 has not yet outlived itself in the good half of the world. In addition, having completed the design, they put a 120mm French smoothbore.

      And why forgive it? Each goes its own way, for example, an instrument of the English Challenger 2, far from the weakest tank in the world ..

        Sereg all the time tormented by the question, what kind of device on Abrams’s guns: rangefinder, target designator, illumination channel?

          on the Abrams gun: rangefinder, target designator, illumination channel

          With the help of this "device" the deflection of the barrel from heating is measured, which has a very favorable effect on the accuracy of shooting, especially at long ranges, since this factor is not one of the last, and it is taken into account "automatically"
          Here is the same on the T90MS

          And on BM Oplot

    Brazilians speak Portuguese, because their forums are difficult to read, but Argentinean forums say that they plan to revive the project of the EE-T2 Osório national tank with their neighbors.

    The Brazilian tank sounds like "4th generation Georgian fighter".)))

    In general, time will tell. First we talk about the merits and qualities of the tank, first breathe it in the heat of battle to experience.
    Drive through the sands, rocks, jungle. Let her know that 4 such a rocket-propelled grenade on board, or 152 mm on the forehead.
    And then the French didn’t stuff a portable brothel into their Leclerc. The UAE was bought according to the principle: "the bad is not expensive."
    And still they don’t know what to do with them — the tank is then a sissy and worse than a muscular young lady.
    My opinion is that the best tanks are the T-4, T-72, T-80A-S, Merkava 90 and probably 4 ranger 4 (they say the armor of this monster only comes from some kind of super-powerful ATGM).

      Why are you doing this? Brazil has a good defense industry. Just a little money is allocated to the defense industry.

          Nothing supernatural. Geography of export on 3 continents. Small arms, various types of grenade launchers, ATGMs, mortars, light armored vehicles, MLRS, light aircraft and transport aircraft. Ships and landing craft.

        The most massive is RPG-7, at least among the enemies of NATO. And they Abrams at a time, sorry, open up.

    Good tank, however. And it does not weigh much, and the characteristics are level. And there is everything. for a country that has no experience in the creation of BTVT and deep traditions in this topic, the creation of such a tank is a definite success.

    It is interesting to read that the countries that have recently taken up the development of the BTT are showing some results ... Of course, judging by the compilation of the same elements from other tanks, they did not say anything new, they just proved to themselves that we could, if necessary .. . Development of a modern MBT and modern weapons in general serves to spur their industry and bring it to the modern level ...

    The tank is very good for its time.
    At the level of Leopard 1 and Challenger, somewhere there is a book with tank weapons of the countries of the world, in it the author gave many advantages to this tank.

    To understand whether a tank is good or not, you need to find out why it was created and does it correspond to the tasks for which it was created? The closest neighbors have the most advanced tank - the Leopard-1 (in various modifications), so if there was a war with your neighbors, Brazilian tanks will be the best. This means that they perform the function of protecting the sovereignty of the country. If Brazil is going to sell them for export, then it all depends on the price.
