Malaysia plans to purchase 16 to 19 units of the EVA 155mm wheeled self-propelled howitzer.
The EVA is a wheeled 155mm self-propelled howitzer fully designed and developed by the Slovak company Konstrukta Defence. It was unveiled in 2015 during the defense exhibition IDET in the Czech Republic.
The EVA is based on a 6×6 all-terrain truck chassis TATRA, but the system can be also mounted on an 8×8 truck chassis.
The gun system of the EVA is mounted on a mobile platform at the rear of the truck chassis and can be fully controlled from inside the crew cabin at the front of the truck. It has a traverse from +60° on each side and an elevation from -3.5° to +75°. The fully automatic loading system is mounted at the rear of the weapon platform with 12 projectiles and 12 powder charges ready to fire. Another 12 projectiles and 12 powder charges are carried in hermetical packing on the truck chassis.
The fully armored cabin has been mounted at the front of the vehicle and has individual seats for the crew of three. The crew cabin is of welded steel armor and provides protection from small arms fire up to 7.62 mm in caliber and shell splinters.
The maximum range depends on the type of ammunition and charge system, but firing an ERFB-BB (Extended Range Full Bore-Base Bleed) a maximum range of 41 km can be achieved.
The EVA has a rate of fire of 5 rounds per minute in automatic mode and 13 rounds per minute in 3 minutes in manual mode. When the system is deployed in the firing position an anchor spade is hydraulically lowered on each side at the rear of the truck chassis to provide a more stable firing platform.
