The FT was the first operational tank to carry a turret. In modern tanks, the turret is armoured for crew protection and rotates a full 360 degrees carrying a single large-calibre tank gun, typically in the range of 105 and 125 mm (4.1 and 4.9 in) calibre. Machine guns may be mounted inside the turret, which on modern tanks is often on a ...
The initial claimed advantage of oscillating turrets was that of reducing the turret size for a large main battle tank gun. In the 1950s, tanks were rapidly growing more heavily armed, larger and heavier. Western armed forces were trying to catch up with the increasingly formidable Soviet tanks, such as the T-55. Weight was the main problem ...
It takes 20 seconds for the T-62's turret to rotate through a full 360°, which is 5 seconds longer than the time needed by the US M60A1 Patton tank. [23] The turret also cannot be traversed with the driver's hatch open. Although the tank commander may override the gunner and traverse the turret, he cannot fire the main gun from his position. [21]
Renault records make no distinction between 1917 and 1918 output; the decision to arm FTs with a 37mm gun was made in April 1917, before any tanks had been manufactured; because of various production difficulties and design requirements, a range of turret types were produced by several manufacturers, but they were all fitted to the basic FT ...
The following year, the French pioneered the use of a full 360° rotation turret in a tank for the first time, with the creation of the Renault FT light tank, with the turret containing the tank's main armament. In addition to the traversable turret, another innovative feature of the FT was its engine located at the rear.
The turrets could rotate about 300 degrees at about 4 degrees per second and could be fired back beyond the beam, sometimes called firing "over the shoulder". A red stripe on the wall of each turret, inches from the railing, marked the limit of the gun's recoil as a safety warning to the turret's crew. [5]
If power was lost, such as when the tank ran out of fuel, the turret could be slowly traversed by hand, assisted by the loader who had an additional wheel, which could manually rotate the turret at a rate of one-half a degree per each revolution of the hand crank; a 20° turret rotation required 40 full cranks of the handwheel, and to turn the ...
The jack-in-the-box effect, [1] also known as a turret toss, is a specific effect of a catastrophic kill on a tank or other turreted armored vehicle in which an ammunition explosion causes the tank's turret to be violently blown off the chassis and into the air.
