Batignolles-Châtillon Char 25T
On the begining of the fifties, development of the very effective HEAT ammunition which basicly negated the (homogenous steel) armor of existing heavy tanks, for the moment revivied the idea of medium tanks. Company Batignolles-Châtillon, renown manufactorer of railway cars and locomotives, started the development of a new medium tank that eventualy evolved into an “as light as posible” main battle tank concept. Batignolles-Châtillon Char 25T had a very flat hull, with 80 mm of highly sloped front armor, hydraulic suspention with six wheels and a oscillating tower.
Oscillating turretThe oscillating turret design, lacking a conventional gun-mantlet, is in two separate parts, with an upper and lower part connected by two hinge bolts or pivots, the gun being fixed within the upper section. The horizontal movement of the gun, traversing, is conventional, but the vertical movement, elevation, is achieved through the pivoting of the entire upper section with respect to the lower section. This method of elevation has two main advantages. Firstly it allows for a smaller turret volume, as no internal space is needed for the vertical movement of the gun breech. Secondly, it allows the use of a relatively simple auto-loader fed by multiround magazines,
Armament and other design features
Main armament consisted of a powerfull 90 mm gun, with initial muzzle velocity of 930 m/s. As a secondary armament, Char 25T had a single 7,5 mm machinegun. With very compact dimensions of only 567 cm in lenght, 316 cm in width, and 237 cm in height, mass of the veichle stayed below 25 tones. With such a low weight, Chart 25T could achive a very high top speed of 65 km/h. The crew consisted of four; a commander and gunner placed in the turret, while the driver and radio operator were placed in the hull.
Batignolles-Châtillon Char 25T lost the competition for the next Frech main battle tank in favour of AMX 30. However a portion of the technology was used in the future vehicles. Main reasons for the defeat were to be found in unreliable and maintenance demanding hydaulical suspension, as well as fading interest in the oscillating turret complex. They were relatively tall (compared to its size) and it was very difficult to make them gas tight. In the era of cold war with a high risk of nuclear and chemical warfare, this was considered as a major flaw. Two prototypes were built.
