Figure 80: UB-13 Rocket Launcher
S-13 rockets can be fitted with different types of warheads. The rocket has the ability to penetrate up
to 3 meters of earth or 1 meter of concrete. Its effective range is 3 km. The S-13T variant has two-
stage action, and detonates inside the target after penetrating (up to 6 m earth or 2 m concrete). It
can create runway craters with an area of 20 sq. meters.
The S-13OF blast-fragmentation variant generates 450 fragments weighing 25–35 g each, and is
effective against unarmored targets.
All of the S-13 rocket variants are designed to be fired from aircraft speeds of 600 – 1200 km/h.
S-13 rockets are fired from B-13L 5-rocket launchers. The launcher has a length of 3558 mm and a
diameter of 410 mm. The empty launcher weight is 160 kg.
Su-17M4, Su-24, Su-25, Su-27, MiG-23, Mig-27 aircraft and Mi-8, Mi-24, Mi-28 and Ka-50 helicopters
can be equipped with S-13 rockets.
S-25 Rocket
The S-25 unguided heavy rocket was produced in two versions, one with the S-25-0 fragmentation
warhead and the other with the S-25-F high explosive warhead.
The 340 mm caliber S-25-F has a length of 3310 mm and launch weight of 480 kg. The high
explosive warhead weighs 190 kg, including 27 kg of explosive, and is equipped with a contact fuse
of varying time delay.
