Participating in the Ministry of National Defense's booth at the National Achievements Exhibition, the improved ZSU 23-4 self-propelled anti-aircraft artillery system (PPK) received public attention.

The ZSU 23-4 self-propelled PPK complex was researched and improved by the Institute of Military Science and Technology, General Staff of the Vietnam People's Army from the fire control system using optoelectronic equipment produced by the Soviet Union in the 60s of the last century. The complex produced by the Soviet Union has the advantages of strong, concentrated firepower, high mobility, and a reliable air defense shield for ground troops.

This complex is still in service in many countries. However, in addition to the fact that the equipment has a long life, the quality of the system has decreased, modern warfare has also changed a lot in terms of methods and targets of combat, the ZSU 23-4 complex is facing the need to improve and upgrade.

The fire control system uses optoelectronic equipment to replace the old generation fire control system and radar equipment equipped for the Zsu 23-4 equipment complex, including the following components: Optoelectronic observation station, central computer block, observation station control and stabilization block, turret; the vehicle crew interface system is manufactured using modern electronic technology, digital for equivalent technical and tactical indicators, some indicators are higher than the original ZSU 23-4 complex, the vehicle's combat modes remain the same, similar to the original radar equipment. 

The main technical solutions to implement the product include: Designing and manufacturing the central computer block to replace the computer block on the original complex; designing, manufacturing and integrating the optoelectronic observation station to replace the old generation radar system on the original complex; designing and manufacturing the turret control and stabilization block to replace the turret control and stabilization block on the original complex; designing and manufacturing a new interface system for the crew to replace the crew interface system on the original complex.

The ZSU 23-4 complex with a fire control system using optoelectronic equipment can be put into training and combat readiness in units of the Air Defense - Air Force. The improved complex has a Vietnamese interface, the control buttons are simpler than the original ZSU 23-4 complex, so training the combat crew to grasp the operation is quite convenient. Currently, the ZSU 23-4 combat crew at the Air Defense - Air Force has been trained to use the improved ZSU 23-4 complex in just 4 weeks and has practiced safe live ammunition firing, achieving high results.

The improved ZSU 23-4 complex product is the basis for implementing the next stages in the process of comprehensively upgrading the ZSU 23-4 self-propelled PPK complex, including upgrading and adding a low-altitude air defense missile system to increase firepower and expand the target destruction range of the equipment; upgrading and adding radar equipment to meet the requirements of combat in all weather conditions of the complex, overcoming the inherent disadvantages of the optoelectronic equipment system; upgrading and comprehensively improving the vehicle power system, fire fighting system, and support system for the driver's position.
