The BM-21 (sometimes known as the M-210) is a 122 millimeter unguided explosive rocket that was utilized mainly by the former Soviet Union and its allies, and is still in service in many countries to this date. It is highly versatile and has been placed on various ground and naval vessels, in large rocket launcher batteries of up to 40 tubes in a turret.

The BM-21 rocket is comparable to other unguided rockets like the [[HVAR]], [[Wgr.41 Spr]], and [[S-13OF]] in terms of firepower and penetrative capability. All of these rockets can decimate light vessels like torpedo boats in a single hit, crippling them and causing often fatal fires. However, in terms of ship-launched naval rockets, the BM-21 outclasses everything at its B.R due to its superior explosive mass and burn time range. Furthermore, the maximum effective range of the rocket is increased greatly by the fact that the fuel burns for almost the entire duration of flight, which is possible as it is almost 9 meters long and contains a lot of fuel.

Currently, this rocket is only present on a single vehicle in game, the Pr.183 BM-21, a motor gun boat at BR 3.0. It is best used as a naval 'artillery' weapon to saturate the capture points or enemy spawn with a barrage of powerful splash damage, which will take out most small boats in the area. However, should the circumstances permit, it can be used as a close support weapon against either groups of small enemy vessels or a single, larger craft. A number of well-placed shots against the weak points (e.g engine rooms or turret ammo storage) of much larger craft such as destroyers will severely incapacitate or immobilize the vessel, or even destroy it if fires or breaches are not repaired quickly enough. It can penetrate the waterline hull armour of many of the bigger ships of the BR it is situated in.

Description

Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the rocket.

Effective damage

Describe the type of damage produced by this type of rocket (high explosive, splash damage, etc)

Comparison with analogues

Give a comparative description of rockets that have firepower equal to this weapon.

Usage in battles

Describe situations when you would utilise this rocket in-game (vehicle, pillbox, base, etc)

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

Cons:

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the article about the variant of the weapon;
  • references to approximate analogues by other nations and research trees.

External links

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • other literature.
