CZE - MKVR (mobilní KV rušič)

MKVR

Mobile medium automated remote controlled jammer, operating in the 1.5 to 30 MHz band with a transmit power of 1000 W. It cancels omnidirectionally. The purpose of the jammer is to detect and jam tactical phonic and data radio links in the HF band. The target of the jammer is communications and command and control systems for troops at the tactical level. Up to 8 frequencies can be jammed simultaneously and the transmit power can be up to 1000 W. MKVR was developed within the MORUS system (modular jammer kit).

During the development and production of the MKVR jammer, the Ministry of Defence of the Czech Republic was inefficient with its budget resources, as the cost of the prototype was estimated by the manufacturer at CZK 63.06 million and CZK 78.86 million was actually spent. During the development of this jammer between 1996 and 2000, intangible assets worth CZK 3,28 million were created, which became unnecessary due to a change in tactical and technical conditions.

The kit is based on KSSK (KSSK-B) container bodies carried by T-815 VPR8 CTS vehicles with CTS 14255-VP container loaders (or T815-2 ARMAX CTS trucks with CTS 14155-VP container loaders). Electric power is supplied by a EC 30 kW power plant pulled from one of the vehicles (or EC 16 kW). A relatively significant part of the built technology in the MKVR set is of German origin (Rohde & Schwarz).

The first MKVR kit was apparently introduced into the armament of one of the battalions of the 11th Military Intelligence and Radio Electronic Warfare Brigade at the turn of the millennium. After the disbandment of the battalion, the system was operated by the 111th Radio-Electronic Reconnaissance and Electronic Warfare Battalion, which was reorganized as the 532nd Electronic Warfare Center in 2005. Two years later, this center was transformed into the 532nd Electronic Warfare Battalion.
