BM-25
The BM-25 was a multiple rocket launcher system from Soviet production. The GRAU index is “2K5 Korschun” (vulture). The system index of the Russian armed forces is "2P5". The missiles are called "3R7".
development
The system was developed in 1953 by the OKB-3 of the research institute NII-88. The SM-44 launch pad was developed in the TsKB-34 design office. The first systems were operational in 1955. The BM-25 was first demonstrated to the public at the October parade in 1957. The BM-25 was only introduced in small numbers to the Soviet land forces . The system was eliminated there in the mid-1970s. In the mid-1980s, all BM-25s were scrapped and replaced by the BM-27 .
technology
A launcher frame with six rockets of 250 mm caliber was mounted on the three-axle KrAZ-214 truck . A rocket launcher was able to fire all six rockets in 6 to 8 seconds. Reloading an empty turret took 10 to 20 minutes. The rockets had a large dispersion and were therefore only suitable for combating area targets.
Missiles
The 3R7 missiles were the only ones in their class to be powered by storable liquid fuel . The rockets had a tail unit with four fixed guide surfaces and were spin stabilized. A slight twist was given to the rocket at launch by the slightly twisted launcher frame. The rockets had a maximum fire speed of 1004 m / s. Shooting distance of 55 km. One rocket weighed 375 kg, 100 kg of which was attributable to the fragmentation warhead .
Spread and use
The system was only exported to southern Yemen . It was only used during the civil war in Yemen . However, the BM-25 did not prove itself due to the extremely large dispersion of the rocket volleys.
