Nothing is impossible for the motherland. - An Akula Missile Sub launches missiles
The Akula Missile Submarine is used by Russia in place of Dreadnoughts, which has the advantage of being submerged while not firing at the cost of being slower.
In the Second Great War, the Russians developed several experimental ballistic missile submarines. Ships capable of launching powerful missiles from incredible distances to annihilate targets with barely any chance of retaliation. Unfortunately for the Russians, these prototypes were destroyed by the Allies. This did not however discourage the Soviets from developing the Akula, the spiritual successor of these missile subs.
Though this massive submersible is very slow, it can emerge from the depths to strike at targets anywhere, making them one of the most feared units in the Russian arsenal. They do not carry any defensive measures, however, and are thus vulnerable when they rise above the waves or are detected. Just like Dreadnought's missiles, the Akula's projectiles can be shot down with AA weapons.
In Puppet Master, around ten minutes into the mission, an Akula Missile Sub will sneak into the city and attack the Psychic Beacon stationed in the centre, in the process freeing the mind controlled Russian forces from Yuri.
The Akula is properly introduced as a buildable unit in Power Hunger, where they are tasked with destroying the ChineseHammer Defenses located on the coast so the Russians can make landfall.
Unlike the Boomer Submarine in Yuri's Revenge, the Akula is able to instantly dive into the sea level (done by using Stop command or S key) when the missiles are ready to fire; the missiles won't disappear but continue igniting and flying to the designated target.
