Description


Introduction

The 140mm M-14 is an early Cold War era series of artillery rockets of Soviet origin. These were developed in the late 1940's for the BM-14 multiple rocket launcher.

Design

Unlike the World War 2 era BM-13 Katushya, the M-14 rockets are both spin stabilized and tube launched. Most of the body is made up of the solid propellant rocket motor. The warhead is located in the upper section and the fuse is screwed into the nose.

Firepower

Maximum range of these artillery rockets is around 10 km. Accuracy is better than the World War 2 era Katushya, but poor by modern standards. The HE-Fragmentation warhead is the most common type. Specialist warhead types have been developed as well.

Users

The M-14 was widely used by Soviet forces and exported to various Soviet allies. With the introduction of the more capable Soviet 122mm BM-21 Grad and the more compact Chinese 107mm Type 63 the M-14 became obsolete in the later stages of the Cold War era.
