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.

General info

Comparison with analogues

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

Usage in battles

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 either as a naval artillery weapon to saturate the capture points or enemy spawn with a barrage of powerful splash damage, or as a close support weapon against groups of small enemy vessels or a single, larger ship. A number of 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. One must keep in mind the rocket turret is on the rear of the craft, so it may be difficult to position or aim at targets directly ahead of it.

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:

• Powerful explosive mass deals good damage against all targets.
• Considerable armor penetration, capable of penetrating and destroying targets like the Maus, modern MBTs, and large ships.

Cons:

• Potentially difficult to aim
• Limited supply of the rockets on the craft.
• Relatively slow rocket speed means fast moving vessels will be able to evade fire.
