The vehicle’s history:

The EE-9 Cascavel was a joint venture bettwen the Brazilian army and Brazilian company Engenheiros Especializados S.A. (Engesa) in the early 1970. The vehicle was designed to meet the needs of the army, which was seeking a 6x6 reconnaissance vehicle for operations on varied terrain. In 1970 it was build the prototype of the vehicle and after undergoing various tests and modifications, it was approved for series production in 1974. In the future Engesa made more versions of the vehicle, with the M4 being the best version, it was adopted by Brazil (CFN): 6 vehicles, Colombia: 128 vehicles, Cyprus: 124 vehicles and Iraq (being the largest user of this version): 364 vehicles.

Basic characteristics:

The Cascavel M4 is a 6x6 wheeled armored reconnaissance vehicle with a crew of three (driver, gunner and commander). The vehicle has a length of 6.29 m (with gun), width of 2.60 meters and height of 2.29 to 2.6 (if it uses the commanders turret). The total weight of the vehicle is 12.5 tons. the vehicle also stores in total 44 rounds.

Turret ET-90 II:

The ET-90 II was first installed on the EE-9 Cascavel M4, becoming standard for all later Cascavel models. The turret is two man crew (commander and gunner), it is capable of receiving modifications such as laser-rangefinders (LV3), NVG devices for both gunner (SS 122) and commander (SS 130 in the ET-7,62 sub-turret/Commander Cupola) and drive-motors for traversing the turret. it stores 24 ammunition, 12 in bustle and 12 in racks behind the gunner and commander seat in the turret basket. It also carried six 76 mm smoke launchers, three on each side of the turret.

Spoiler

Firepower:

The EE-9 Cascavel M4 uses the improved EC-90 III (Engesa’s licence produced Cockerill 90 mm low pressure cannon) with a recoil stroke of 500 mm. As secondary armament, it had a Coaxial 7.62×51 M971 (FN MAG) machine gun and a roof-mounted .50 or a 7.62 machine gun mounted on the turret or attached to a ET-7,62 sub-turret.

Armor/Protection:

The EE-9 Cascavel M4 is made with bimetal steel, which offered an improved protection to weight ratio compared to standard steel, the Bimetal armor offered around 1.8 times the effective thickness of an equivalent homogeneous plate against .50 and 1.5 times against 7.62 mm ammunition, meaning the Cascavel had an effective homogeneous thickness of 28.8 mm at the front and 15.3 mm at the sides and rear against 7.62 mm fire, meanwhile it had effective homogeneous thickness of 24 mm at the front and 12.75 mm at the sides and rear against .50 ammunition.

Turret:

Front and Sides: around 16 mm
Top: 8mm

ET-7,62 sub-turret/Commander Cupola:

all around: 8mm

Hull:

Front upper hull plates: 16 mm
Sides and Rear: 8.5 mm
Top and Floor: 6.5 mm

Suspension:

The vehicle was 6 x 6 driven, of which the rear 4 wheels were part of the boomerang suspension. The boomerang suspension, in combination with the Engesa 2 speed transfer case, would enable it to cross challenging terrain and provide maximum traction in most situations. The power of the engine was distributed to a differential on the front side of the vehicle, and a differential in the rear. The rear differential drove the boomerang suspension with a single axle, which made the boomerang suspension such an ingenious design.

Spoiler

Engine:

The EE-9 Cascavel M4 was specifically designed, built and sold with the Detroit Diesel 6V53 engine with a power of 212 horsepower. The engine allows the vehicle to reach a maximum speed of 100 km/h on roads and a range of up to 750 km.

Spoiler

Transmission:

The Cascavel M4 uses the Detroit Diesel Allison MT-643 automatic transmission.

A vehicle with a lot of personality, I would love to see you in the game in a future Latin American tree.

I had no idea that the EC-90 was put in so many different APCs! If Gaijin added the EE-9 to the game I’d really like them to add at least one of these too. They’d be some interesting goblin tanks.

[VEIO_da_HAVAN]

There are more modifications, in the future I will use the 20mm cannon and the 25mm cannon, and the best is the 30mm cannon called torc30

I would love to see that BTR-50/OS-62 variant in the game. Either in the USSR tree or a future arab nations tree.

[VEIO_da_HAVAN]

There are many variants of Engesa vehicles, little by little I will post them here

Speaking of modified Iraqi Cascavels, here is a EE-9 Cascavel with the 2A28 Grom cannon and add-on armour

Iraq also replaced the original 90mm cannon with a 37mm M1939 autocannon on at least one of them

Brazil needs attention in warthunder. Arguably, the entirety of South America, they have like 1 or 2 nations represented in the game.

[VEIO_da_HAVAN]

Thank you for your message, Brazil has many interesting vehicles, for example the EE-9 has many varieties of guns and engines that were used all over the world, all that’s left is for Gaijin to be interested, the Brazilian community plays War Thunder a lot

[AWACS Ghost Eye]

Italian players and a lot of Brazilian players advocated for Brazil to be the Italian subtree, mostly because of the famous Smoking Snakes and their effort to liberate Italy, as well as modern day collaborations such as the AMX and centauro 2. However, this never came to fruition: and given that coalitional trees were feasible, I am very confident that you guys and other South American players can put together a tech tree.

[Lattrell_Spencer]

Hope one day EE-9 come to Warthunder.

[Lattrell_Spencer]

I have a question, does the EE-9’s turret and cannon have stabilizers?
