The ST-T finished its testing by April 1969. Finally, the prototype turret was mounted on top of the ST-T and again conducted firing test. The 105mm cannon was later loaded onto the ST-T hull and conducted firing test. In August 1967, the 10ZF engine replaced the prototype engine. Length was 6.64m, width was 3.06m, and height was 1.95m. The ST-T alone weighed 21 tons but fully rigged, it weighed 35 tons. The coaxial gear steering, hydro pneumatic suspension and the 700 horsepower class engine have started testing together on a test bed called the ST-T in March 1966. This device maneuvered the rounds close to the breech of the cannon to enable the loader to reload faster. A load assisting device was also introduced into the turret. In 19, aiming and turret rotation tests were carried out. In the picture below, the end part is the breech and the segment between that and mantlet is the recoil system.ДЄ prototype turret was completed when the 105mm cannon was mounted on it in 1966. From 1966 until 1967, firing tests were carried out. The Japanese final version resembled the US M68 105mm version the most.

The full length of the cannon, including all parts just mentioned, was 5,592mm long and the total weight was 2,800kg. They built their own breech, recoil system and mantlet around the cannon.

The part that Japan imported for license production was only the barrel. Actual testing of it using a Type 60 APC prototype called the SU began in 1962.ДЇor fire power, they opted for a license on the NATO standard Royal Ordnance 105mm cannon. Research on the hydro pneumatic suspension began as soon as the Type 61 tank was completed in 1961. By March 1965, an air cooled 700 horse power class engine has been developed.

These were a new and stronger engine, a hydro pneumatic suspension, and a coaxial gear steering device which would improve the transfer of engine power. Prior to the 1965 decision to design an entirely new tank, some technologies which would later be used in the STB-1 were already in development independently in Japan. After their success, the second phase began and consisted of the STB-3, STB-4, STB-5, and STB-6 prototypes.

The STB-2 was virtually identical to the STB-1. So the 1 in STB-1 indicates the first prototype vehicle. The number that comes after is the cordial number for the prototype vehicle. But when the tank entered the hands of the testers, they removed the hyphen for whatever reason, making just STA and STB. The developers actually wrote it by separating it with a hyphen like ST-A and ST-B.

So in the case of the Type 61, its code was STA. And the B represents the Type 74 development program. In the code name STB, the ST represents tank. In 1965, the decision was made to design an entirely new tank which launched the STB program. Japanese tank engineer Kondo pointed out that not only a 105mm cannon but also mobility, target acquisition, and rate of fire must all be good for the sake of combined arms operations. Whichever the decision was going to be, the key feature would be a 105mm cannon. They debated over either improving the Type 61 (Type 61 Kai) or designing an entirely new tank.

The incapability of JapanвЂ™s Type 61 tank to match these newer tanks prompted a heated debate. In the early 1960s, in the mists of the cold war, European, American, and Soviet tanks were progressing from the M48, T-55, and Centurion 3 class of tanks to the M60, Leopard 1, T-62 class of tanks. The STB-1 is indeed an imposing tank and would be a very competitive tier 10 tank in World of Tanks. Despite its technical and rather unimposing name, the first phase was an ambitious and successful creation while the second phase was largely about taking a katana to the cost of the tank while improving endurance and reliability. The STB-1 was the first of two development phases in the development of the Type 74. Enjoy!ДЄfter the culmination of many tested core components, the STB-1 was completed in 1969. Hello everyone, today we have another article from Soukoudragon, (revised by Daigensui) this time about (sort of confirmed) Japanese tier 10 tank.
