O DANA é uma peça de artilharia autopropulsada com rodas. Também é conhecido como Samohybná Kanónová Húfnica vzor 77 (ShKH vz. 77; obus de canhão autopropulsado modelo 77). Foi projetado por Konštrukta Trenčín e construído pela ZTS Dubnica nad Váhom na antiga Tchecoslováquia (atual Eslováquia). Introduzido na década de 1970, foi o primeiro canhão de artilharia autopropulsado de 152 mm com rodas a entrar em serviço. É baseado em um chassi Tatra 815 modificado com tração nas oito rodas (8×8) com excelente mobilidade cross-country.

A Bold Departure from Tracked Tradition
O SpGH DANA (Samohybná Kanónová Húfnica vzor 77) was a landmark in artillery design. Developed in Czechoslovakia in the late 1970s, it was the first wheeled 152 mm self-propelled gun to enter service. At a time when Soviet doctrine favored heavy tracked vehicles like the 2S3 Akatsiya, the DANA utilized a modified 8×8 Tatra 815 chassis. This choice provided superior strategic mobility, reduced maintenance costs, and a high road speed, all while maintaining impressive off-road performance thanks to its unique central tire inflation system and independent suspension.

The Unique Split Turret and Autoloader
- Innovative Layout: The turret is split into two halves, with the gun mounted in an open cradle in the center. This layout allowed for a powerful automatic loading system—a rarity at the time—which could load shells at any elevation angle.
- The Tatra Advantage: The air-cooled Tatra V12 engine meant the vehicle had no radiator to freeze or leak, making it highly effective in the harsh winters of Eastern Europe.
- Stabilization: Prior to firing, the DANA deploys three large hydraulic stabilizers (one at the rear and two on the sides) to provide a steady firing platform, compensating for the lack of weight compared to tracked systems.
- Fire Control: Modernized versions (like the DANA M1 and M2) feature digital fire control systems (FCS) and GPS, allowing for “shoot-and-scoot” tactics to avoid counter-battery fire.
Combat History and Modern Evolution
- Operational History: The DANA has seen extensive combat, from the Chadian–Libyan conflict and the 2008 Russo-Georgian War to the current conflict in Ukraine. It is highly regarded for its reliability and speed on the move.
- Successors and Cousins: The DANA’s design success led directly to the Slovak Zuzana, which swapped the 152mm gun for a NATO-standard 155mm L/45 barrel.
- The “DITA” and “MORANA”: The latest Czech evolutions feature a fully autonomous turret, reducing the crew to just two members (Driver and Commander), essentially making it a robotic artillery platform.
