# 155 mm SpGH Zuzana

Zuzana 155 mm Gun Howitzer is a Slovak artillery system developed by Konštrukta – Defence, with a 45-caliber gun and automatic loader for loading of both projectile and charge. It is an evolution of the 152mm SpGH DANA self-propelled howitzer.
The gun has a long range, high accuracy, and high rate of fire, it can be prepared promptly for firing, and it has a high level of mobility ensured by a modified Tatra 8×8 chassis. The design of the gun means it can use any NATO standard 155 mm ammunition. The fire control system allows for a multiple-round simultaneous-impact (MRSI) mode. One of the unique features of Zuzana is that the gun is mounted externally in between two totally separated compartments of the turret. This makes the crew inherently safe from any potentially dangerous mechanics of the gun and its autoloader. Additionally, the crew is protected from the gasses generated during firing.
