## Background History

The Russian "Borei" class Nuclear powered Ballistic Missile submarines (SSBN), designation project 955, is a class of 6 submarines at the time of writing. The class is intended to replace the older Delta III, Delta IV and Typhoon class SSBNs, although the Borei is in fact much smaller. This particular ship, the Yuriy Dolgorukiy, was the first ship of the class, and served as the basis for the NATO name of this class: "Dolgorukiy". The ship was scheduled for launch by 2002, however was delayed by budget constraints. The ship was eventually launched on 15 April 2007, although not put into the water until February the next year, and it's sea trials began on 19 June 2009 in the White Sea, although commissioning was hampered by problems with the Bulava ballistic missile. The launch of the Yuriy Dolgorukiy was momentous, being the first SSBN launched by the Russian navy in 17 years since the end of the cold war.

## Overview

The Yuri Dolgorukiy is the most durable submarine there is, but its weapon slots are only average. Its main selling point is it's vaunted ability to pretty much camp underwater for most of a game, allowing you to avoid most forms of damage. This combined with its extremely tanky HP pool makes it an absolute demon to surface vessels and carriers especially towards the end of a match.

## Tactics

### When Playing as a Dolgorukiy:

Stay with an aircraft carrier or cruiser. They can defend you from missiles and aircraft with their very powerful AA defenses, and stave off enemy submarines with their ASW assets. Otherwise, form a wolfpack with friendly submarines to boost each others firepower and collective defense against enemy subs. If those options are not available to you, abuse your unmatched O2 capacity to its fullest, stay underwater for as long as possible and spam missiles and torpedoes with virtual impunity at your enemies. Surface whenever it is safe to stock up on as much O2 as possible. As you reach the endgame, it could be the difference between victory and defeat. When fully upgraded, your ship can stay underwater for well over 5 minutes in a single sitting.

### When Playing Along with a Dolgorukiy:

If you are using a surface ship, escort it. You can protect it with air defense and grenade launchers, allowing the Yuriy more freedom to do what they need to. As a fellow submarine, especially as a Type 096 or an SMX-31, you can provide a much needed anti submarine defense for the Yuriy against enemy submarines particularly other Type 096's and help bolster the overall firepower of the Dolgourkiy.

### When Playing Against a Dolgorukiy:

Attack it with aircraft. It is vulnerable to them. Use torpedoes as well. It is also recommended to use grenade launchers if its underwater as it can stay there for over half the game. Submarines are the best weapon against a Dolgorukiy with SMX-31 and Type 096 being the ever effective bane of anything underwater at Tier III.

## Suggested Armaments Setup

The ship, with its flexible armaments setup, can be equipped with different weapons. But, bear in mind that these are only suggestions.

Torpedo(first slot): Mark 48, UGST Physic, A244 SLWT, YU-7

Torpedo(second slot): Mark 48, UGST Physic, A244 SLWT, YU-7

Missile(first slot): S-500 Prometheus, RIM-161 SM-3, RIM-174 SM-6 (better SM-3, requires level 25 and 1.5k gold)

Missile(second slot): Zircon(for players with the "Hero" status), UGM-133 Trident II, or RSM-56 Bulava

## Advantages and Disadvantages

**Advantages:**

1. Highest submarine durability.(That is not CN type 100)
2. Largest oxygen capacity for submarines, can stay underwater for more than 5 mins.
3. access to two separate torpedo tubes, allowing for more flexible loadout options compared to the Ohio.
4. One of the missile slots is 2x, saving you some cash as you don't need to buy a separate weapon and fully upgrade it.

**Disadvantages:**

1. Only has 2 missile slots that can fire 3 missiles.
2. Very vulnerable to aircraft especially bombers.

## Trivia

* The ship used to cost around 10 million dollars; but was increased to 14,000,000 on January 17, 2022.
* The Borei class ships are actually essentially stretched Akula III hulls fitted with pump jet propulsion and a SLBM section. This had the advantage of simplifying maintenance and giving high speed and quiet performance as the hull is derived from a fast attack sub, one of the best out there at that.
* The borei class is the first Russian SSBN to be launched in 17 years since the end of the cold war.
