Not every country in the world has the ability to increase the range of BM-21 Grad rocket artillery like Vietnam.
 |
| Specifically, the BM-21M-1 rocket artillery has the ability to calculate, calibrate and automatically control the firing elements quickly and accurately; integrate information systems, data transmission to ensure operations in all terrain and weather conditions, day and night. Previously, the crew of the BM-21 rocket artillery had 5 people, now with the BM-21M-1, the crew is reduced to 4 people. The pre-firing preparation time of the BM-21 is 14 minutes, now the pre-firing preparation time of the BM-21M-1 is only 1.5 minutes. Photo source: QPVN |

| The control of the range and direction of the BM-21 rocket cannon is semi-manual or manual, after being improved into the BM-21M-1 rocket cannon, it can be done automatically, semi-manually or manually. Similarly, previously the BM-21 rocket cannon calculated the firing element manually, now with the BM-21M-1, the calculation of the firing element is done automatically. Photo source: QPVN |

| With these two major upgrades: increased mobility and increased firing range, the already dangerous BM-21 Grad's attack capability is now even more dangerous. It is still an indispensable fire attack for Vietnamese artillery. Photo source: QPVN |

| The BM-21 launcher is equipped with a 40-barrel 122mm launcher mounted on a 6x6 Ural-375D or Ural-4320 (in service since 1976) wheeled transport vehicle. All 40 shells can be launched in just 20 seconds, but can be fired one at a time or several times a few seconds apart. Reloading is done manually and takes about 10 minutes.

| A rocket artillery battalion equipped with all BM-21s can fire up to 720 shells simultaneously within 20 seconds at targets over a wide area, making it very effective against infantry and light armor formations, as well as for destroying semi-fortified trench systems. Photo source: Wikipedia |

| In recent years, in addition to research projects to upgrade T-54B tanks, B72 anti-tank missiles and some other types of armored vehicles, the General Department of Engineering has also actively implemented many projects to improve and manufacture new equipment for artillery troops. With tireless efforts, the General Department of Engineering, in coordination with factories and enterprises across the army, has successfully manufactured 105mm self-propelled guns on the Ural-375D or Ural-432007-10 chassis. In addition, the General Department of Engineering also directly directed the project to successfully improve the BM-21 Grad rocket artillery. Photo source: QPVN |

| The BM-21 Grad rocket artillery is one of the most powerful and destructive types of artillery of the Vietnam People's Army today. This type of artillery can attack and destroy enemy infantry, defensive fortifications, and armored vehicles within a very large range, with extremely terrible damage. Photo source: QPVN |

| However, being born with technology from the 1960s of the last century, BM-21 Grad also revealed many weaknesses in modern warfare. Therefore, the General Department of Engineering has directed agencies and departments to implement a series of upgrading and modernization measures. Up to now, many positive results have been achieved. Photo source: QPVN |

| Specifically, we have completed the work of increasing the firing range of rockets equipped for the BM-21 Grad multiple launch rocket system. That means the firing range of Grad will not stop at 20km but will be further. Unfortunately, the QĐND Online newspaper did not provide detailed information on the topic. Photo source: QĐND |
 |
| However, currently the Russian Grad versions have been increased in range with new types of rockets with ranges up to 30km (9M218) or 40km (9M521). Perhaps the ability of Vietnam's extended-range rockets can also be based on these models. Photo source: QDND |

| In addition to increasing the firing range, the General Department of Engineering also upgraded the fire control system to provide faster and more accurate attacks. In the photo, the improved BM-21M-1 rocket artillery was introduced at the Army Party Congress. Photo source: VOV |

| After being improved, the BM-21M-1 rocket artillery has overcome the basic limitations of the BM-21 rocket artillery, thereby improving technical and tactical features, especially the ability to automatically calculate and control fire. Photo source: QPVN |
