Description

The S-21 rocket (scale is approximate)

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

• MiG-15bis
• ◊MiG-15bis
• J-2
• MiG-17
• MiG-17AS
• J-4

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

For heavily armoured vehicles, the best utility of the rockets is to try and aim towards the roof of the tanks. The blast would more than likely penetrate through and devastate their crew compartments. Even in a near-miss, the rockets have a chance of damaging the tracks to hinder the enemy movement in another pass. In some cases, aiming at the area of the track deliberately is doable to attack the weaker belly and side armour of the tank.

Very lightly-armoured vehicles can be critically damaged if the rocket lands around maximum of 3 m from target. So aim carefully and hope the rocket connects close enough to destroy the enemy.

Pros and cons

Pros:

• A rocket full of high-explosive characteristics - a direct hit can result in elimination or a severe critical damage to the enemy
• Decent penetration of 62 mm can deal with most weak-points in armoured vehicles
• Fires one-by-one that allow for a more steady follow-up shot against targets
• Does not automatically explode

Cons:

• Slow projectile

History

Describe 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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.
