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.
