Created as a shared project between Konstrukta Defense and ZTS Special, using technology developed for
SpGH Zuzana 2. Utilizes a 155 mm gun, 52-caliber, achieving a range of up to using specialized ERFB-BB munition. Firing rate is stated as up to 5 rounds in the first minute, and 13 rounds in 3 minutes. Carries 24 rounds in automatic magazines ready to fire. The operation is fully automated and can be performed from the inside of the armored cabin.
Multiple round simultaneous impact firing mode is supported and the howitzer can be connected to command and control system of a battalion battery. High mobility is achieved by using Tatra 815 6×6 chassis, however the developer states that there is an option for 8×8. The model presented in 2015 offers range of up to and speed of using the 6×6 chassis. Dimensions and weight were kept under the limits of
C-130, achieving high strategic mobility for the system. Compared to competing designs of similar concept, EVA offers compact design, low weight and high range, ability to be transported using C-130 planes, as well as full automation of the firing with minimal crew needed.). The shooting capabilities, structural integrity, and mobility were all evaluated. This variant is based on the Tatra 815 6×6 and is equipped with an armoured cabin. The fire control system is processing on its own the firing solutions for the system. It takes into account the weather information, the ballistic, the topography, and the targeting information.The barrel's position is automatically aiming at the target, and an auto-loader is loading the canon. == Operators ==
