In November of 1984, shortly before Gorbachev came to power, a Typhoon-class Soviet submarine surfaced just South of the Grand Banks. It then sank in deep water, apparently suffering a radiation problem. Unconfirmed reports indicated some of the crew were rescued. But according to repeated statements by both Soviet and American governments, nothing of what you are about to see… ever happened.


----------------------------------------------------------


As you may have noticed, this is not an exact copy of the submarine Red October as she appeared in the movie. As it turns out, the movie version has a lot of problems, some stemming from the imperfect information available to the western public at the time (e.g. the incorrect stern arrangement and the placement of the missile tubes), and some stemming from alterations made to ease production (e.g. the simplification of the shape of the sail). While these problems could be accounted for if we assume Red October was a brand new design, and not a modified Typhoon, this clashes with some of the cannon and in general makes little sense (as the design shown in the move would not be the best possible design if you’re not already constrained by the arrangement of a Typhoon class).

As such, I decided to reimagine Red October in a way that is more realistic. I’ve used an actual Typhoon class as a base, and made several modifications to allow for her new role. Hull plugs were inserted both fore and aft of the sail, with the aft plug being by far the largest. These added both the additional buoyancy and internal volume needed to house a series of turbo-electric generators hooked up to the main reactors, and the electromagnets and other machinery associated with the Magnetohydrodynamic Drive. The channels the MHD drive uses run down the sides of the boat, with twin openings forwards, before merging just aft of the main ballast tank and exiting underneath the main rudder assembly. This allows the thrust from the drive to be relatively in-line with the center of mass, therefore reducing the amount of deflection on the dive planes needed to maintain a level depth. This does require the main rudder post for the ventral rudder assembly to run through the channel, however since the electromagnets for the drive are located further forwards, this is not a major issue.

In addition, the twenty R-39 SLBM tubes have been replaced with an equal number of R-29RM tubes, which reduces weight and allows for the MHD machinery to be installed without requiring excessively large hull plugs. This change is also more accommodating of her mission, since Red October is designed to use her silent drive to sail within several hundred kilometers of the US coastline before launching an attack, and so missiles with a long range would be unnecessary.

I actually think this version of the Red October look cool.

Projekt 144 Admiral Horthy-class

Image

Sandwiched between the resurgent USSR and the Western Alliance the Republic of Bereznik was eager to develop its own nuclear deterrent. In 1964 the first ballistic missile submarine entered service but was a converted diesel submarine with a missile that could only be launched on the surface.

Professor Laryak's rocket design group amended the design of the new R-19 missile with pre-stored liquid propellants for naval use with the capability for underwater launch. The first R-21 made its maiden flight in 1966 and work began on a new submarine to carry it. The easiest way to do this was to take the proven Passat-class nuclear attack submarine (the first of which entered service in 1963) and insert a missile compartment for six R-21 missiles. The conning tower was lengthened and modified by the addition of Italian SP-7B passive sonar arrays at both ends of the tower. A VLF communication buoy was also fitted to the aft end of the tower. The usual armament of six 533mm torpedo tubes was retained as were the MS-8 and MTS-3 bow sonars from the Passat-class. The R-21 had a range of 3,500km and was armed with a 1MT warhead.
The first submarine - named after Admiral Horthy - was commissioned on 24 July 1969 and served until 1989. She was followed by three sisters, completed during 1970-72. The class was soon replaced by a purpose-built successor design with twelve missile tubes from 1974.

Shinryu Class SSBN:

Born in a time of major realignment of Koko's military policies, the ominously named Shinryu (abyssal dragon), namesake of a class of five, was the first Kokoan SSBN, and first nuclear-powered submarine as well.
Given its novel nature, Kokoan designers recieved some assistance from the United States Navy during its development, with some components imported from the US or built under license. The submarine was built around its S1N pressurized water reactor -a developement of the US S5W designed by Nijima industries- and twelve missile silos for as many Poseidon SLBMs. Laid down in 1975 at Kumoi Shipbuilding Industries (former Kumoi Arsenal) she was launched in 1980 and commissioned in 1982, recieving an upgrade from Poseidon to Trident-I missiles in 1988.
After an uneventful career (a positive for an SSBN) Shinryuu reached the time for her mid-life refuel and overhaul in the late 90s, but ultimately got none. Due to post-cold war budget cuts she was decommissioned in 1999 and entered her recyle and disposal phase in 2007.

Developed in the Early 2000s as a replacement for the earlier B-3 class of Bombers following their success during the 1998 "One China Crisis", the B-5 Peacemaker II was the second generation of US Air Force Ballistic Missile Submarines. Although larger, quieter and with a longer endurance than the preceding B-3s, the B-5s was armed with an identical payload, a quartet of UGM-118A "Sea-Keeper" MX Missiles carried in individual canisters beneath fairings atop the pressure hull. Defensive Armament composed a pair of torpedo tubes at the bow. An additional smaller diameter tube dedicated to deploying countermeasures and SLOT Buoys buoys was located at the stern. A towed communications buoy was carried on the stern for communications with the National Command Authority while remaining at depth Although USAF Submarines are well known for their flashy and distinctive Sail Art, the designs are not actually painted onto the Sail and are instead removable decals. These decals are typically only displayed while in port or on short training cruises and are removed prior to patrols. A typical patrol was around three to four months. As is typical with western SSBNs they operated on the two crew concept, as opposed to the Gold/Blue terminology of the USN, the USAF used the terms Day and Night.

Pictured is MX-05-931, like all USAF Submarines she was legally classified as an aircraft and as such was assigned a serial number rather than an official name. Officially she was designated as MX-05-931, unofficially she was alternatively nicknamed "Lucky Shot" by her "Day" crew and "Okay Boomer" by her "Night" Crew. As per USAF Submariner tradition she was "renamed" at the end of each patrol in an unofficial ceremony. The ceremony would see the Boat's Sail Art being removed and replaced with the relieving Crew's mascot, an event followed by a barbecue and beers.

The Hegaretmara-class is a product of a mid-4280s program intended to bolster the existing fleet of four Shequi-class Strategic Nuclear Submarines following the decommissioning of the Gelian-class with a larger, more capable vessels.

The ships were eventually constructed in two batches. The largest difference between the two types is the modified design of the missile silos, allowing for the installation of a canister for five anti-ship missiles in place of a single ballistic missile. This was to allow for the boats to be denuclearized in periods of reduced tension while retaining the ability to rearm them with ballistic missiles should the need ever arise. The last two ships of the class, the Balavehtsawe and Vatueil were built to a slightly stretched design, to accommodate docking facilities for special operations submarines initially intended to operate off of the cancelled PS.083 Bermoiya-class attack submarines.

The Skoric Stochlin-Class Ballistic Missile Submarine SkMV Berg

The SkMV Berg is a part of the Stochlin class of nuclear-powered ballistic missile submarines built for the Skoric navy. Each boat is capable of deploying twelve BKN-4 ballistic missiles, each able to deliver five warheads. The total amount of deliverable nuclear warheads for each boat is sixty nuclear warheads, with the entire class deploying a total of 1,200 warheads. They were to replace the older Skerat class of ballistic missile submarines. Apart from being manufactured using relatively new techniques, it also has a whole host of new technologies that sets it apart from the Skerat class. Automation has resulted in a much higher efficiency in the operation of the boat, but also in higher reliability. A higher-yield nuclear reactor was also installed to meet the increased energy requirements.

Ships of this class:

SkMV Berg SkMV Veuross SkMV Stermvorg SkMV Svartovorg SkMV Torovorg

SkMV Hildegard SkMV Feldamak SkMV Stalfena SkMV Seurat SkMV Femborg

SkMV Stirrborg SkMV Helnnovorg SkMV Sorne SkMV Alfenak SkMV Astelfovorg

SkMV Liaborg SkMV Theamak SkMV Kerrakutz SkMV Albetenborg SkMV Ontarrdernborg

Some important facts relating to the depicted submarine:

The SkMV Berg is most infamous, due to it being connected to the 2010 sinking of the SS Beauty of the Sea. According to a ten-year-long investigation involving five countries, the civilian cruiseliner was thought to be torpedoed by accident having been misidentified as the Deysian oil tanker Cheriav--which it was ordered to destroy. Fragments of the torpedo recovered traced back to that of the Stochlin class, with the SkMV Berg being suspected as being responsible for the sinking, as it departed in the morning on a 'classified' mission. The Skoric Daugrech maintains that the destruction of the cruiseliner was done by a Deysian submarine, and not that of a Skoric one, of which that is highly unlikely. Deysia does not operate any submarines.

Another interesting fact is the discoloration of some of the submarine's anechoic tiles, which are definitely not from wear and tear. This quote follows.
"-They're made by different factories with ever so slightly different materials and processes. Not enough to affect function, but enough that they appear slightly different colors when side by side."-Some naval engineer.

Type 077 Class SSBN

Image

In the late 1960's, the Sayikoian Navy began designing and building a new class of larger, purpose built SSBN's to follow up the earlier, Type 074 Class which were designed in the mid 1960's, which were mostly experimental boats to see if Sayikoia's shipyards could produce a nuclear ballistic missile submarine. The Type 077 would be a longer, larger submarine, that was able to be produced in higher quantities, with 16 large SLBM's, that would be able to strike targets remaining much closer to friendly arctic waters. The first boat was laid down in 1979, and a total of 32 Type 077's would be produced in three distinct blocks, each with iterative design improvements, until 1990.
