The ShKH vz. 77 (acronym for Samohybná Kanónová Húfnica vzor 77, “model 77 self-propelled howitzer gun”) or DANA (acronym for Dělo automobilní nabíjené automaticky, “automatically loaded self-propelled gun” in Czech) is a wheeled self-propelled howitzer of 152 mm caliber. It was designed in Czechoslovakia in the 1970s by Konštrukta Trenčín and built by ZTS in Dubnica nad Váhom, in present-day Slovakia. Commissioned in 1981, it was the first operational 152 mm wheeled self-propelled artillery gun. In the Czech Republic they continued to develop this vehicle with new fully automated versions that can be operated even by only 2 crew members, such as the DANA M2, while in Slovakia they chose to move to the 155 mm caliber with the ShKH vz. 2000 Zuzana. The DITA is a version of the DANA M2 with a standard 155mm NATO barrel.
