The mobile S-300 was initially developed to defend Moscow in a ring of fixed sites. In the late 1980s a mobile version of the SA-10 was completed. This version of the weapon is carried and vertically launched from a dedicated four-round capacity transporter-erector launcher vehicle. The Russian version is based on the MAZ-7910 8 x 8 truck chassis.

The SA-10 mobile missile battery comprises the combined FLAP LID B radar and command guidance system mounted on a MAZ-7910 and up to 12 mobile SA-10 launch units, each equipped with four Grumble missiles. When traveling the missiles are carried in the horizontal position and rotated to the vertical position before firing at the pre-designated launch site.


Senior Russian aerospace officials admitted that they are testing new SAM missiles against the F-117 that was shot down by Serb forces in 1999. The Russians admitted that the F-117 was being used to test new anti-stealth technology and advanced missiles designed to shoot down U.S. aircraft. Russian researchers are testing components of a new air defense system against the F-117 remains.

The Russian anti-stealth tests include radio frequency seekers from surface-to-air missiles and proximity fuses for missile warheads. Russian missile makers Antey Industrial Corp. and the Almaz Central Design Bureau are using the F-117 and modified Russian-made stealth aircraft to test components for the next generation of Russian Surface to Air Missiles (SAMs).

Almaz engineers claim its S-300PMU-2 system can locate and destroy stealth targets up to 60 miles away. Almaz is currently trying to sell the S-300PMU-2 to China.



The recently disclosed DWL002 is a modern and technically sophisticated digital Emitter Locating System, which builds on ideas employed in the earlier YLC-20 ELS. While design employs much the same DTOA and Angle Of Arrival [AOA] techniques as the much older Russian, Ukrainian and Czech ELS systems, the DWL002 introduces an important innovation, which is the use of paired primary wideband apertures, displaced in elevation. The resulting phase and time differences between the upper and lower antennas permit heightfinding, otherwise problematic in earlier single aperture designs.

The primary apertures are housed under cylindrical radomes, in an arrangement similar to the KRTP-91 Tamara and ERA Vera systems.

The lower primary aperture is on a telescoping mast, the upper primary aperture on the articulated folding main mast, which employs hydraulic actuators.

Below the upper primary aperture is a package of steerable parabolic antennas, likely operating in the upper X-band or Ku-band. These are employed to provide high data rate links between the three or four networked DWL002 systems when deployed.

The aft of the equipment container also mounts three Yagi antennas, the purpose of which has not been disclosed. It is most likely that these are employed for datalinking target track data from the networked DWL002 systems to other air defence assets.

The system is carried on a North Benz ND1260 (Mercedes-Benz NG 80) 6 x 6 military truck, common to recent radar designs such as the YLC-2V, JY-11B, JYL-1, YLC-18, Type 120, Type 305A and Type 305B. This will result in similar onroad and offroad performance.

The strategic significance of the DWL002 is that it is the first DTOA technology ELS which has been designed from the outset with the intention of providing robust heightfinding capability when passively tracking an emitting target. The ability to generate near-realtime or soft realtime 3D target tracks would be especially valuable in supporting SAM systems like the S-300PMU2 or HQ-9, as this could be employed to cue the SAM engagement radar very precisely to the inbound target. Should the accuracy of the ELS be sufficiently high, it could be employed to generate post-launch midcourse tracking corrections for outbound SAMs.

The CETC brochure describes the system thus:

“DWL002 Passive Detection System, also called as passive radar, is mainly used in air-defense or seashore monitoring to perform the detection to perform the detection and location to airborne, shipborne or landbased emitters in complex electromagnetic environment and display the target flight path in real time. The system can also operate together with active detection system to form a mutual supplementary surveillance network.

Typical configuration of DVL002 Passive Detection 'system is composed of three reconnaissance stations. One of them serves as master station and the other two as slave stations. The system can be expandable to four station configuration with perfect performance of full spatial coverage and altitude information of air target. Each station is carried by an individual vehicle.

Main Functions:
* Realtime & Accurate Location and Tracking
* Signal Analysis and Identification
* Long Range Detection and Early Warning

Main Features:
* Passive
* Real Time
* Very Good Mobility

DWL002 Passive Detection System is a three station configuration (expandable to four station configuration). Each station. including antenna and power generator. is housed and carried by one vehicle. which ensures the good mobility of the system

* Remote Control
* Advanced techniques

Long base line time difference of arrival (TDOA) location technique combined with AOA: Wideband digitized receiver technique; Multilevel correlation processing technique with good flight track processing result: Automatic set up. Chassis leveling techniques and automatic north calibration technique to ensure fast deployment and flexible operation.”

Russia fielding metric-wave anti-stealth radar.

In mid-January, Gen. Col. Vladimir Mikhailov, Commander of the Russian Air Force, announced that Russia will undertake an extensive modernization of its national air-defense system. The space-defense and air-defense networks will be integrated to higher degree and new concepts of operations will be also developed. From the equipment point of view, the new S-400 system will be fielded this year, along with modernization work on existing S-300PM and S-300PM1 systems. For the first time, it was also reported that the Pantsir S-1 system will be evaluated and considered for fielding for the role of close-in defense of medium- and long-range surface-to-air-missile (SAM) sites. Gen. Mikhailov said that there is a high interest in the system within Russian Air Force.

Along with the S-400, the 55Zh6-1 Nebo-U radar sets are also to be fielded this year. The radar was developed by NNIIRT [Nizhnonovgorod's Rsearch and Development Institute of Radio Technology] (Nizhny Novgorod, Russia) and has the distinction of probably being the only radar in the world with a digital phased-array antenna that works in the metric-wave band. The radar has one horizontal and one vertical antenna of large size and deeply modified Yagi-type aerials. The radar's range is up to 600 km for targets flying between 40-75,000 m, 400 km for targets at 20,000 m, 300 km for targets at 10,000 m, and at least 65 km for targets flying at 500m.
