EVA (howitzer)

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 41 km with ERFB-BB ammunition.

Design
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 41 km 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 6x6 chassis, however the developer states that there is an option for 8x8. The model presented in 2015 offers range of up to 700 km and speed of 80 km/h using the 6x6 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.
