EVA is a Slovak-made self-propelled howitzer, developed by Konstrukta Defence and publicly revealed in 2015. The EVA is based on a Tatra 815 6x6 truck, but the system can be also mounted on a 8x8 truck chassis. It is armed with a 155 mm / L52 howitzer and has a maximum firing range of 41km (25miles) with ERFB-BB ammunition.[2] [3]
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 41km (25miles) 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 700km (400miles) and speed of 80km/h 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.

In August 2024, Konstrukta Defence tested the EVA M2 variant (iniatially revealed in September 2023 under a name BIA[5]). 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.[6]
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.
