Poltanyy Class Nuclear Attack Submarine

The Poltanyy class nuclear attack submarine is a Marnin 3rd generation attack submarine. Intended for service in exclusively Marniya, however, considered for shipment to Sayikoia or Jasinovalkia. The Poltanyy class shares a unique feature unlike western counterparts, a Titanium hull. This enables the Poltanyy to dive deeper than its counterparts, which is essential for Marnin naval doctrine.

The ship is commonly characterized for its high operational depth and speed, as well as its deadly arsenal of weaponry used in its role of engaging hostile attack submarines and nuclear capable submarines. The ship obtains high speeds using a lead bismuth cooled fast reactor, which delivered an overall better power to the turbine shaft.

Preproduction
The idea of the Poltanyy class was first theorized in 1960, as a direct response to the shift in naval doctrine. The previous class and class in the making were deemed unfit for the job that the new doctrine specified. This meant that designers would have to reengineer the nuclear submarine from what they had been previously doing. Over the course of 4 years, testing and designing of new hulls, engines, and propellers were done to make a submarine that could dive deeper, and travel faster than western counterparts.

By 1966, the answer was found, and after hundreds of calculations and scale model testing, the new Marnin 3rd gen submarine the Solkantava was constructed with two in its class. The Solkantava was the first Marnin sub to use the new titanium hull and lead bismuth reactor, and entered service in 1971, however immediately after the first two and only were constructed in its class, the new submarine was deemed as too expensive to further produce. By 1972, a new design was already under way, made to be cheaper than the Solkantava.

The new design came in the form of the Poltanyy, the overall design of the submarine was much more streamlined compared to the Solkantava, this allowed for even greater top speeds through water. As well as the impovements to the speed, the submarine recieved a new generation of Marnin submarine launched AShMs,
