Everything started much earlier, even in the mid-seventies when the military leadership of the JNA became aware that the issue of the purchase of a new tank cannot be postponed indefinitely. The military leadership of the JNA decided to purchase new tanks cannot hold off. Given that 35 percent of the tank fleet accounted for the old T-34 models. The only newer models were T-55 tanks that were already about 20 years old. The tanks model, which was interested in military experts of the JNA, was the T-72 produced by the Soviet Union (USSR). But Moscow has explicitly announced that negotiations for the sale of licenses for the production of this model do not come into consideration.

Only after intervention at the highest level, the Soviet Union received a group of experts from Yugoslavia which was screened T-72. The Tank demonstration was conducted at the military academy Vistrel, 30 kilometers from Moscow. After the demonstration, the experts' impressions were uneven, but the final conclusion was that this is the best tank and that it can be produced in Yugoslavia based on the license. Based on reports from the expert group and the opinion of the Military Council and the Military Military Technical Council, a decision was made to purchase a tank T-72 license. Finally, the license was sold for $ 39 million, with a duration of 10 years or 1,000 produced tanks.

The next step was the agreement on which plants will produce a tank. Each Yugoslav republic wanting to acquire as much percentage as possible in the production process. It was uncertain and who will be the finalist for production, and in the competition were the factory Đura Đaković from Slavonski Brod, Goša from Smederevska Palanka and Mechanical Institute in Nis. - Let's be what the experts say. As far as the finisher of the production of the tank is concerned, as experts claim that all three companies have approximately the same production conditions, and as Croatia has the lowest percentage of engagement in military programs, let the finalist of the tank be in Croatia, and to finish it. - Tito decided

Prior to the start of production was to get many machines and equipment. For the technological process should be available press force pushing 30,000 tons, with additional presses of 5,000 and 10,000 tons. In the competition of several companies, this technology was given to the Aluminum Combine from Podgorica.

Arrived license document are together weighed about 20.000kg.

Ultimately, the cost of training to start production of tanks cost $ 3,08 billion, and the production process was attended by 240 factories, and indirectly another 1,000 work organizations.
