''In the description, the first part should be about the history of and the creation and combat usage of the aircraft, as well as its key features. In the second part, tell the reader about the aircraft in the game. Insert a screenshot of the vehicle, so that if the novice player does not remember the vehicle by name, he will immediately understand what kind of vehicle the article is talking about.''

The BB-1 depth charge (Russian: Бомба Большая (Глубинная), ''Large bomb (depth)'' ) is a larger version of the [[BM-1 small depth charge|BM-1]] (Russian: Бомба Малая (Глубинная), ''Small bomb (depth)'') and is present in War Thunder on naval vessels belonging to USSR.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].
 
  
−
== General info ==
+
Depth charge mechanics in War Thunder are very basic, being simple, medium-sized bombs deployed from naval vessels. Their area of effect is almost precisely vertically upwards, somewhat alike torpedoes, except depth charges, do not move from their deployed location except to sink.

=== Flight performance ===

The depth charges produce focused splash damage right above their location, like a vertical torpedo.

<!-- ''Describe situations when you would utilise this bomb in-game (vehicle, pillbox, base, etc)'' -->

Depth charges require much more skill to serve any purpose in comparison to torpedoes, due to the fact you either have to be very close to the opponent or you have to predict the path the opponents may take.
  
−
=== Manual Engine Control ===
+
An important aspect of using depth charges is to set its activation time (depth charges do not have proximity fuses). You can set the activation time before battle, whenever you have depth charges installed. It is recommended to use some time in the middle (5-8s) to allow some variety, but if you know that you are going to face faster boats (earlier tiers) or slower, larger boats (later tiers), then you can use a faster activation time (3-5s) or a slower activation time (7-10s) respectively.

=== Modules ===

There two main strategies for using depth charges in battle: 1) cutting in-front of enemies and planting depth charges, usually in a motorboat; 2) planting depth charges around the perimeter of a strategic point before enemies pass through. The former strategy can be adapted to suit close-quarter battles when the opponent is right up against your side where you can plant the depth charge and hope that the splash damage hull-break the opponent; the latter strategy requires an above-average game sense and knowledge of the map.

Description

The BB-1 depth charge (Russian: Бомба Большая (Глубинная), Large bomb (depth) ) is a larger version of the BM-1 (Russian: Бомба Малая (Глубинная), Small bomb (depth)) and is present in War Thunder on naval vessels belonging to USSR.

Depth charge mechanics in War Thunder are very basic, being simple, medium-sized bombs deployed from naval vessels. Their area of effect is almost precisely vertically upwards, somewhat alike torpedoes, except depth charges, do not move from their deployed location except to sink.

General info

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

BB-1 Depth Charges on the Soviet BMO.

Effective damage

The depth charges produce focused splash damage right above their location, like a vertical torpedo. Although originally they were designed to produce both explosive and shockwave damage underwater to destroy submarines, in War Thunder, there are no submarine vehicles and as a result, the depth charges have a very focused area of effect.

Comparison with analogues

The depth charges are comparable to static torpedoes which explode after a time delay. Numbers-wise, the BB-1 depth charges are comparable to a 150 kg bomb.

Usage in battles

Depth charges require much more skill to serve any purpose in comparison to torpedoes, due to the fact you either have to be very close to the opponent or you have to predict the path the opponents may take.

An important aspect of using depth charges is to set its activation time (depth charges do not have proximity fuses). You can set the activation time before battle, whenever you have depth charges installed. It is recommended to use some time in the middle (5-8s) to allow some variety, but if you know that you are going to face faster boats (earlier tiers) or slower, larger boats (later tiers), then you can use a faster activation time (3-5s) or a slower activation time (7-10s) respectively.

There two main strategies for using depth charges in battle: 1) cutting in-front of enemies and planting depth charges, usually in a motorboat; 2) planting depth charges around the perimeter of a strategic point before enemies pass through. The former strategy can be adapted to suit close-quarter battles when the opponent is right up against your side where you can plant the depth charge and hope that the splash damage hull-break the opponent; the latter strategy requires an above-average game sense and knowledge of the map.

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:

  • Very powerful weapon when used strategically
  • Can have a time delay from 3 to 10 seconds, allowing for a variety of uses (short-term grenade placed in-front of opponents or more long-term strategic 'mine' placement)

Cons:

  • Difficult to use effectively, due to its 'static' nature

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

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
