This armour was an improved variant of the ''Clona-1'' explosive reactive armour found on the HT-75. A new gas-turbine engine was developed and installed on Type 710 in 1984. The new Clona-2 ERA was integrated into the design of the turret and hull. The Type 710 was further upgraded in 1985 with a new 125mm smoothbore gun and accompying fire control system. This new fire control system added a laser range finder and thermal imaging sights. Armor was added to the front rubber side skirts. In 1987, the Type 710 underwent acceptance trials by the Ministry of Defense. The tank received the designation, HT-85.

The HT-90 Pružný is a Holyn main battle tank developed by Kubeš Machine Building Design Bureau. The HT-90 is a development of the HT-85/75, first introduced in 1975, the HT-90 introduced a number of new features such as a hard kill active protection system and new welded turret. The tank has been in service with the Royal Holyn Defence Force and its predecessor, the Holyn Armed Forces, since 1999. The HT-90 features a 6 cylinder, 1,200 hp engine with a power-to-weight ratio of 26 horssepower per tonne. This replaced the HT-85s gas-turbine engine following cost issues during development. An upgraded version the HT-90P was introduced in 2010 and is currently in production. The tank was designed and built by Kubeš Machine Building Design Bureau in Kubes, Holynia.
History
Development
In 1983, the HT-75 underwent an modernisation program aimed to improve reliability and situational awareness. The prototype model would be called Type 710. Type 710 started simply as a HT-75 chassis. During the course of development, Clona-2 (English: Shield-2) explosive reactive armour was developed by Slatnik State University School of Engineering. This armour was an improved variant of the Clona-1 explosive reactive armour found on the HT-75. A new gas-turbine engine was developed and installed on Type 710 in 1984. The new Clona-2 ERA was integrated into the design of the turret and hull. The Type 710 was further upgraded in 1985 with a new 125mm smoothbore gun and accompying fire control system. This new fire control system added a laser range finder and thermal imaging sights. Armor was added to the front rubber side skirts. In 1987, the Type 710 underwent acceptance trials by the Ministry of Defense. The tank received the designation, HT-85. Serial production began in 1989 and the first tanks were delivered the the Holyn Army by late 1989. Further improvements continued in the 1990s, with the HT-85 receiving a new thermal sight for the commander.
In 1992, Clona-3 explosive reactive armor was trialed. The promising results saw a new prototype tank, the Type 770 main battle tank begin development. A new welded turret was constructed to better fit the Clona-3 blocks. Other improvements were introduced including a soft kill active protection system with dazzlers, laser warning system and smoke grenades. An improved gas turbine engine was also installed, with over 1,500 horsepower and reduced fuel consumption. The Type 770 was well received by officials from the Ministry of Defence, however economic issues in Holynia prevented an order being placed in 1994. Funding for development continued, allowing further improvements to the Type 770.
