Dana (wz. 77) 152 mm Self-Propelled Howitzer is one of the older armament systems operated by the Polish Army. Despite the fact that the system faces a number of effectiveness-related limitations, when it comes to the contemporary operational context, the system remains accurate, reliable and it is well known in Poland. And because all of the aforesaid factors, certain plans for modifying this platform have been made. The systems based on wheeled platforms, in essence, are viewed as cheaper counterparts of the tracked systems. There is a need to provide artillery support for the elements involved in operational activities, where use of tracked systems would be made more difficult or simply cost ineffective.

Following the modifications, Dana’s lifetime may be extended for another 25 years.

The DANA (Dělo Automobilní Nabíjené Automaticky) is a wheeled self-propelled howitzer and was designed by Konštrukta Trenčín and built by ZTS Dubnica nad Váhom in the former Czechoslovakia (now Slovakia). Despite the long lifetime and lack of more significant upgrades (apart from adding the Topaz ZZKO fire control system, RRC9500 radio, Fonet comms system and Tallinn 5000 land navigation suite), Danas are considered to be one of the more successful artillery system designs. The aforesaid platform also still exhibits a certain potential, when it comes to possible upgrades. The howitzer offers some protection for the crew (ballistic, IED and ABC), and comfort for the crew. Dana also features an autoloader and carries a major quantity of ammunition. Furthermore, the system may be fired within 225 degrees angle, horizontally.
