The MMWT is equipped with a Cockerill CT-CV 105HP (High Pressure) 105 mm rifled gun manufactured by CMI (Cockerill Maintenance & Ingenierie SA Defense), with the barrel mounting a bore evacuator and thermal jacket. Based on the experience gained from the tests, improvements were made in the tower system, power transmission group, cooling system and suspension system. The body design was perfected in line with the feedback from the end user. In this context, driver visibility and handling ergonomics have been improved. Many improvements were made to the tank during the transition from prototype to mass production. In IDEF 2021 (17-20 August 2021), the production model of Harimau / Kaplan MT is revealed. On 7 February 2020, it was announced that mass production of the MMWT has started. He stated that the first batch of 20 to 25 tanks could be ordered as early as late 2018, and that the full number of tanks to be produced would likely fall between 200 and 400. On 5 September 2018, the general manager of FNSS told Turkey's Anadolu Agency that the tank had passed months of required qualification tests for the Indonesian Army, and was ready for mass production.

Additionally, the tank utilizes modular armor, allowing for quick replacement upon damage.

The tank can be fitted with either a Cockerill XC-8 105mm concept turret or Cockerill 3105 modular turret. On at the IDEF 2017 expo, the first prototype of the tank was revealed. Most notably, the vehicles overall weight was reported to be around 35 tonnes, and the main armament would be provided by a Belgian-made turret developed by CMI Defence featuring a 105 mm rifled barrel, capable of firing a wide range of projectiles. On 1 November 2016, during the 2016 Indo Defence expo, the first model of the tank was unveiled, along with some technical specifications. The intellectual property of the design was agreed upon to be shared between the two governments. The development phase of the program was expected to take up to 37 months, with the first prototype being built in Turkey, and the second in Indonesia.

The governments of Indonesia and Turkey first agreed in May 2015 to jointly develop the MMWT for the Indonesian Army at a reported cost of 30 million US dollars.
