Tajikistan receives new Pechora-2M system
Stefan Marx
Tajikistan has taken delivery of the new Almaz-Antey S-125-2M Pechora-2M (SA-3 'Goa') surface-to-air missile system, according to Russian press reports in early December.
The standard being delivered represents a further upgrade of an earlier configuration shown for the first time in 2003.
Both the control post vehicle and the UNK command post vehicle are based on the KAMAZ-4320 chassis and are networked with a CASTA-2E2 reconnaissance and target-designation radar based on the same chassis or on a trailer.
The new SRN-125M-2M version of the 'Low Blow' radar is also based on the KAMAZ-4320 chassis. It has two target channels and can handle up to eight launchers. Both figures are double the number available in the unmodified system, but from these limited technical details it is not possible to deduce the number of targets that can be tracked simultaneously or the number of missiles that can be launched simultaneously.
The new 5P73-2 launcher is based on a MZKT-8021 6x6 heavy truck made by the Minsk Wheel Tractor Plant and consists of a chassis and a turntable with launching rails for two upgraded 5V27DE missiles. (The definitive version of the original system used a 5P73 four-rail transportable launcher.)
All of the main electronic components have been replaced with new digital equivalents. This has improved the system's accuracy and has also enhanced the resistance to countermeasures.
The maximum distance between the UNV radar and the UNK command post is 150 m, while the control post can be located up to 10 km away. Set-up time after reaching a deployment location has been reduced to between 20 and 30 minutes - well below the 90 minutes needed for the unmodified system.
The modernised missile has a new rocket motor and a new warhead with a radio-controlled fuze. Although it has the same speed as earlier versions (between 700 and 1,000 m/s), the maximum range has been increased from 24 km to 32 km.
Targets for the S-125-2M system include fixed- and rotary-wing aircraft, unmanned aerial vehicles and cruise missiles. According to the manufacturer, the kill probability against a cruise missile is 55 per cent for a single missile and to up to 80 per cent for a two-round salvo.
During the 1999 NATO air campaign against the former Yugoslavia, an S-125 system successfully downed a US Air Force F-117 stealth fighter. With the S-125-M, Almaz-Antey claims that the detection range against a stealth aircraft has been increased from a maximum of 16 km to more than 30 km. As with the claimed performance against cruise missiles, no specific target type is given.
New communications links, land navigation systems and electronic interfaces allow the Pechora-2 command-and-control system to receive radar information from various sources, including sensors from the S-300 air-defence missile system.
As a result of the redesigned electronics, maintenance time is reduced by a factor of between eight and 10, the company claims, and life-cycle costs are reduced. The number of spare parts that must be stocked has been reduced from 3,000 items to only 300.
