P-18H Radar

Brief description of P-18H radar
Due to its meter wavelength range, the radar is able to detect aircrafts using stealth technology. The radar spare parts base is based on the latest commercial off-the-shelf items. Transmitter is solid state type based on pulse-compression principle. Test and diagnostic equipment are built in. The modernization improves the surveillance probability, the path of air targets is automatically tracked. The station is able to receive data from other radars, the information exchange between radars is based on agreed exchange protocol. The radar requires low maintenance, in case of newly built-in units the mean time between failures level is high (approx. 12.000 operating hours).

Description of modernization implemented on P-18 long range locator by HM Arzenál Zrt.:
The radar has newly developed hardware. The frequency range was extended and the operational frequency is increased from 4 to 41, allowing the immediate automatic frequency tuning.
The transmitter and receiver units consist of only solid state elements. The transmitter consists of modular systems, which greatly facilitates the correction of possible failures.
In the new radar station, number of vehicles is reduced from 4 to 2: equipment vehicle, antenna vehicle.
An aggregator is integrated in the equipment vehicle, which provides the radar’s smooth operation in case of power failure using an uninterruptible power supply.

Mistral Air Defense Missile System

The HM Arzenál Co. has successfully co-operated with the French-English Matra BAe Dynamics (MBD) - the winner of the "Short-range air defense missile" tender, furthermore its Italian-Swiss subcontractor, the Oerlikon Contraves (OC).

The tender's results has been announced at the beginning of year 1997. The winner had to meet its obligation to supply three Mistral air defense missile batteries till the end of year 1999. The Hungarian party specified such requirements concerning the structure and equipment of the missile batteries, for which the MBD did not dispose of outlined solutions.

The French party entered into a contract with the HM Arzenál Co. to satisfy these requirements and to perform the necessary developments and production. The HM Arzenál Co. developed and manufactured in a needed amount the Atlas Interface Platform in the frame of this contract which resolved the mounting of the MISTRAL air defense missile launch pads onto the transporting vehicles and the storing and transportation of equipment directly needed for the combat operation.

The HM Arzenál Co. furthermore developed and manufactured the company- and battery-level logistic vehicles for the transportation and operation of different spare parts and auxiliary materials, tools, test and communication devices.

Similarly, in the course of this program, the HM Arzenál Co. - as a subcontractor of the OC - manufactured the radar housings of the fire control radars of air defense missile batteries (Mistral Command Post) and the digital signal processing electronics with SMD technology. As a result of the successful co-operation the HM Arzenál Co. was the first company in Hungary, which got "NATO supplier" qualification.

The MISTRAL air defense missile system has been made suitable for the co-operation with the K-1P fire control system in 2004 . The computerized workplace of the Mistral Command Post got a TCO terminal, which is the same unit that is built in the fire control radar (SZURN) of the SA-6 system.

K-1P Fire Control Station Modernization

The K-1P fire control system came into existence with the moderization of the Russian made K-1M complex which is the automatic centralized fire control system of various Russian missile and conventional air defense systems.

The regimental command post of the original K-1M complex was the KBU shelter that received the orders of the superior KBU and the analog signals of the local radars. The regiment had no recognized air picture (RAP) at disposal, combat operations were based solely on local sensor data. The seven-strong combat crew evaluated the analog radar information and executed manual fire distribution.

The system sent target coordinates to the battery command post (KPC) through wire or radio connection. The KPC received this telecode information and formed the neccessary analog control signals for the fire control radar (SZURN). After locking on the target the SZURN controlled the launchers and executed destruction independently.

Main features of moderization
• Modification of the K-1M complex to be suited to receive and process NATO standard data communication and fire control information
• At the command level where the K-1P system is integrated into the command and control system possibility of external control through Link11B  protocol is also solved
• The system is constructed in such a way that it can be made suitable for controlling other air defense systems by replacing the fire control radar's interface unit (e.g. MISTRAL)
• Introduction of encrypted communication
• Computer aided fire distribution
• Removing the battery command post (KPC) for faster response
• Major improvement of the complex's availability time and reliability
• Simplification of deployment, reduction of number of connection cables

Modernization of AK-63F Assault Rifle

The HM ARZENÁL ZRt. is dealing with the modernization of AK-63F assault rifle since the beginning of 2013, using all of its experience acquired in the field of weapon modernization in the recent years.

The manufacturing of the original AK-63F has begun in 1964, and its huge advantage, next to other assault rifles, is that it works well between -40 and +50 Celsius degrees. One of its drawbacks was that no optical sight or any other accessories e.g. tactical lamp could be placed or fixed onto it properly.

The design of the modernized assault rifle provides the mounting of modern targeting devices and other accessories, thus it creates the possibility of prompt and accurate firing during day- and nighttime, as well as under extreme climatic conditions.


Partial modernization of "Watchman" and "AR-51" radars - replacement of signal processing and plotter system. The following systems were replaced: signal processing system, plotter system, path forming system, remote control, displaying unit. These systems and units were developed and manufactured by the company. In these areas M.o.D. ARZENÁL Co. applied the most modern, industrial and military used components, parts and equipment. As a result of the modernization much more controlling activity can be performed from the operators workplace, and the work of the operators became more secure.

The self-written softwares provided opportunities for further simplifications. With the evolving of remote control, most of the locator activities can be tracked through an IP based network and controlled from a remote centre.


M.o.D. ARZENAL Electromechanical Stock Company Central Measuring Laboratory
The Central Measuring Laboratory has been operating within the frameworks of the M.o.D. ARZENÁL Co. for more than 40 years (since 1966). Previously, it was the number one calibration/validation laboratory of its predecessor and for the Hungarian Army and its main task was the precision control of electronic measuring equipment, which included the calibration of pressure and temperature gauges.

The main requirement was the calibration of the measuring equipment, which was used for the repair of military devices and the repair of measuring equipment of the military devices that was sent to the repairing base. Nowadays, this equipment must comply with the requirements of the quality management systems. (ISO, AQAP).

 The laboratory is continuously functioning as an accredited laboratory since 1992, and it is open to civil orders. It is currently working in the accredited status - in 18 measurement areas - under the supervision of the National Accreditation Board (NAT). The main requirement for it is the successful annual review.

The main areas of measuring (see it in the summary table) covers pressure, temperature and electrical measurements. Electrical measurement covers different measuring types from dc measurements to high-frequency measurements. The metering professionals of the lab have about 35-40 years experiences, and they also acquired the necessary knowledge for measuring of specific military equipment.


Hungarian military industry developed SPSS-1000 (Saker Portable Surveillance System), a short-range, portable, and versatile scanning system, which is suitable for moving targets close to the surface (persons, living, moving objects). It is capable of determining their distance, speed and size.

The SPSS is ideal for monitoring borders and free space as well as for monitoring protected military and civilian properties. Its low weight and mechanical design allows easy and rapid installation and transport. The SAKER radar is compliant to MIL-STD 461 standard.

The flexibility of technology provides the possibility to change the main characteristics according to the customers' requirements. The radar withstands the extreme weather conditions (snow, rain, fog), and it provides reliable and accurate measurement. In automatic remote operation mode (1-10 remote radar) one person is required for operating, which results a cost-effective operation.

General description
SPSS – 1000 (Saker Portable Surveillance System) is a short range, portable versatile FMCW based locator system which is appropriate to locate any target moving on the ground or near to ground in the air, detecting the distance, direction, and velocity of the object. It is capable of observing borders, civil or military areas and buildings.
