The BM-14 is a series of multiple rocket launchers of Soviet origin. The BM-14 was developed in the late 1940's to replace the famous BM-13 and its design was partly inspired by the German Nebelwerfer.

The BM-14 is a conventional design, usually consisting of two rows of eight launch tubes. Aiming is done with an indirect fire sight attached to the launcher. The rockets feature solid propellant, are spin stabilized and do not feature wings. Several types of warheads are available.

All BM-14 launchers feature 16 or 17 launch tubes for the same family of 140mm M-140 rockets. They can be ripple fired in 10 seconds and have a range of 9.5 km. The accuracy is limited due to the lack of wings. The warhead types include HE-Frag, smoke and chemical.

All BM-14 launchers do not feature any protection from direct and indirect fire or NBC threats. The launcher is operated, fired and reloaded outside the vehicle.

The BM-14 launcher has been fitted to four types of 4x4 and 6x6 military trucks, providing it with good mobility on roads and reasonable mobility in the field. The RPU-14 is a towed version which is usually towed by jeeps or light trucks. It can also be manhandled over short distances in the field.

The BM-14 was adopted by Soviet forces, various Warsaw Pact nations and many Soviet allies in Africa, Asia and the Middle East. They have been used in various conflicts, but most have been replaced by the later and more capable BM-21 Grad. Nowadays the BM-14 is considered obsolete and hardly any remain in service.
