Typhoon attack submarine

History
When Stalin fought in Great World War Two, he utilised a fleet of submarines in order to attempt to dominate the seas. Although the Soviet Union was forced to disarm after his defeat, Romanov realised that a fleet of new submarines would be vital for a new secret attack force to destroy Allied forces in the United States. With this in mind, he commissioned a new force of submarines, under the direction of General Vladimir. This new force of submarines was even more potent than the first, capable of remaining permanently submerged, unless heavily damaged or detected by Allied forces.

Description
The Typhoon Attack Submarine was a swift attack submarine employed by Soviet forces during the third Great World War. It was equipped with torpedo launchers, along with, naturally, ballast tanks allowing it to remain stable and submerged. The Typhoon was the Soviet Navy's primary naval unit, and was capable of attacking all enemy naval units.

Uses
Soviet commanders swiftly returned to classic tactics of submarine warfare. For the Typhoon, stealth was the best option unless it was part of a large fleet of the submersibles. Commanders used Typhoons to engage isolated enemy units, and to pick off weak opponents from the edges of Allied convoys. Anything not protected by destroyers were the easy targets of Typhoons. Even the mighty Allied Aircraft Carrier was useless against the Typhoons, as long as they remained invisible. However, although they were vulnerable to Allied destroyers, Soviet commanders realised that destroyers were relatively fragile, and by carefully targeting with the Typhoons, Allied destroyers could be destroyed before their Ospreys could attack.

Counters
In order to counter the menace provided by the Typhoons, Allied commanders quickly adjusted their strategies. First of all, destroyers were always tasked to protect other Allied ships. Furthermore, Allied commmanders learned to pinpoint the position of a Typhoon according to the trails of the torpedoes. Subsequently, the commanders could force Allied units to fire upon that spot, even though the units could not actually see the submarine. Furthermore, Allied Destroyer patrols were adept at targeting and sinking Typhoons. The Allies trained dolphins, which already swam underwater, to deliver powerful sonic weaponry that could breach the submarines' hulls. Finally, when they were detected, Typhoons were vulnerable to all forms of attack, especially aircraft and land units, which the Typhoon could not counter. Also, Tanya or Navy SEALs could swim to a Typhoon and sink it with C4 explosives, assuming they were not torpedoed first. They were also completely outmatched by the Boomer missile and attack submarine, which had far better armour, twice the amount of fire power, roughly equal speed, faster firing speed, and greater range, however the Typhoon cost only half as much as the boomer and with the industrial plant cost only 3/8ths as much, and could swarm the boomers. However, one-on-one combat is only advised for elite Typhoons, as recruit and veteran typhoons cannot deal with them.

World War 3
The Typhoon was replaced by the more versatile Akula submarine before the real World War 3, however its design was the base for the third generation of the Soviet submarine.
