In the years before the Third World War, the Japanese billionaire Tokugawa Ieyasu privately funded a biological research station and industrial/mining outpost on Titan. Hidden away from the rest of humanity, the scientists opened up new frontiers in the field of human genetic manipulation. Three major projects were undertaken; modifying the human genome to increase tolerance to environmental factors, such as temperature or gravity, improving the terraforming technology used to alter Titan’s atmosphere and increasing biological resistance to damage, enabling the creation of more capable soldiers.
In the immediate aftermath of the war, the remnants of the Japanese government attempted to provide relief efforts to most of the surviving population, while evacuating key personal to the Japanese moon base. Tokugawa offered an alternative by using his own shipping line to evacuate a substantial number of Japanese nationals to Titan, along with what could be salvaged from the remaining Japanese industry. The civilian authorities ordered him to desist and turn over his ships to their control. Tokugawa ignored their demands and instead offered sanctuary to the families of any military forces that joined his organization. With little left on Earth to defend, the remaining Japanese naval and land forces switched their allegiance to Tokugawa. They also fulfilled a request from Tokugawa to rescue the Emperor and bring him to Titan.
Everyone evacuated to Titan, including the military forces, had to sign a waiver agreeing to two conditions. Firstly, for the purposes of ensuring everyone worked for the common survival, there would be strict hierarchy of command on Titan. The Emperor would remain as head of state, while Tokugawa would administer Titan in the Emperor’s name. The second condition was that the inhabitants of Titan would agree to undergo the necessary genetic improvements to adapt to the hostile environment. As the years passed, Tokugawa established a feudal system on Titan, styling himself as Shogun and his key lieutenants as Daimyo, or Lords. His descendants adopted the role and the line of Tokugawa Shoguns is uninterrupted.
Titan has been terraformed to the maximum extent possible and in 2150 has a surface temperature of -44C. The atmosphere is the densest in the Sol system at 3.25 atm and contains 52% Aestusium, 44% Nitrogen and 4% Oxygen. The two 127,000-ton Mikura class Terraforming Stations that performed this task remain in orbit. Since the creation of the Shogunate, the entire population of seven hundred million has been genetically modified into a new species. Homo Titanis has a temperature tolerance from -46C to 14C, which brings Titan within the low end of the ideal habitable range, while still enabling Homo Titanis to survive on Earth, Mars, Luna and all the Jovian moons except Io. The gravity and oxygen requirements of Homo Titanis have also been shifted downwards, with ranges of 0.07G to 1.33G and 0.07 atm to 0.21 atm respectively.
While the Jovian Federation promotes service to the state as a virtue and the People’s Republic of Terra sees its armed forces as the instrument of future expansion, the Titan Shogunate has the most militaristic outlook of any Solarian power. Bushido, the Way of the Warrior, is at the heart of Shogunate culture. Courage, honour, prowess in the martial arts and, above all, loyalty are the virtues to which all citizens aspire. Due to its origin as a research station, the Shogunate is the second most advanced power in the Sol system, although it trails the Martian Republic by some distance and is much closer in capability to the Jovian Federation and the Colonial Coalition.
Naval Forces of the Shogunate of TitanThe Shogunate Kaigun, usually shortened to Kaigun, is unique among the Solarian powers in that it does not use any form of missiles, either for attack or defence. Instead, all Shogunate ship-based weapons are kinetic in nature; either railguns or gauss cannon. The two other defining characteristic of the Kaigun designs are the use of shield generators and the high percentage of hull space dedicated to engines. The latter makes the warships of the Shogunate Kaigun faster than those of any opponent except the Classis Martia. The doctrine of the Kaigun is simple. Close to point blank range, defending against any missile attack on approach, and destroy the enemy.
Ship Designs
The Kongo class strike cruiser is the primary combatant of the Shogunate Kaigun. Compared to other designs of similar size, it dedicates a lower percentage of hull space to offensive weapons. As the mission of the Kongo is to survive to reach close range and then destroy the target, the design is focused on resisting hostile missile attack. Four twin gauss cannon turrets are the primary defence, generating twenty-four shots every five seconds. The eight Katsura-Takagi KT-20 Railguns are also capable of being used in a point defence mode, with their rate of fire compensating for their low tracking speed. If missiles do penetrate those defences the damage will be absorbed by the shields, which will regenerate after each strike. Finally, if sufficient weight of fire overcomes the shields, the Kongo still has substantial armour to withstand the impact. Eight Kongos are in service.

The Akagi class Strike Carrier is intended to accompany the Kongo and provide a variety of tactical options. The Akagi has no active defences and more limited passive defences than the Kongo. However, it can deploy its twelve Reisen class Strikefighters as an anti-missile escort. While the Katsura-Takagi KT-10 Railgun of the Reisen cannot be turret-mounted, the Reisen has sufficient speed to enhance the railgun’s point defence capability. In fact, when the volume of fire and tracking speed are combined, the twelve Reisens generate a similar defensive capability to the four twin gauss turrets of the Kongo. The Reisens can perform raiding missions against lightly defended targets and accompany the Kongos into point-blank battle. However, they are not suitable for long-range unsupported strikes against well-armed hostile fleets. The two Musashi class Assault Transports are intended for boarding operations and each carry a Rikusentai formation (see ground forces section). Three Akagi class carriers are in service.

The Shogunate Kaigun is unusual in using a commercial vessel for geological surveys. The Kuroshima class is a straightforward design, with excellent survey capability and range, plus a CIWS for defence. While lacking the missiles of the Colonial Magellan, the strong defences of the Martian Angelus and the sensor capabilities of the Jovian Armstrong and Terran Lapérouse, the Kuroshima performs its core task extremely well and with minimal support required. Four have been constructed.

Although the Hosho class Troop Transport is one of the smaller vessels of its type, it is also one of the best defended. With a solid armour belt and twin CIWS, it can withstand low levels of hostile fire. This is in part due to the unique drop capability possessed by the Hosho. Unlike the transports of other nations, the Hosho can drop its troops from orbit, so it is much more likely to be in a situation where it faces hostile fire. Four are currently in service.

The Warriors of the Shogunate of Titan (WST)The Shogunate army is a highly capable, infantry-focused force. All of its infantry are genetically engineered to have a higher resistance to damage and are split into three types. The Ashigaru are similar to the Colonial Marines, in that they are usually equipped with powered armour and improved personal weapons. However, damage sufficient to kill a Colonial Marine would only have a forty percent chance of killing an Ashigaru. The Samurai have the same genetic enhancements as the Ashigaru and are equipped with heavy powered armour and a weapon equivalent to the crew-served machine guns of other powers. Finally, the Samurai Rikusentai are Samurai with the necessary training and equipment for boarding combat.
The majority of the army is organised into Sonae, which are formations with a broad capability. Each Sonae comprises six hundred Ashigaru, two hundred and forty Samurai, one hundred and twenty Yumi Ashigaru, equipped with light anti-tank weapons, twelve Nagae Ashigaru, equipped with light anti-air weapons, twelve Konida, which provide logistic support, two Narimono and the Samurai-daisho who commands the Sonae. The Narimono is unique to the WST and allows liaison between the Sonae and any ground support fighters or ships providing orbital fire support. Four Sonae may operate together with a Honjin formation, which provides support from Horokubiya (medium artillery) and Tekkan (medium anti-aircraft) as well as additional Konida units.
There are three other formations within the WST. The Kiba-tai is a formation of sixty Kiba-musha Tank Destroyers, equipped with two medium anti-vehicle weapons, which is only deployed when the Sonae encounter heavy armour. These armoured forces are regarded as a necessary evil by the Shogunate, but have less prestige than the Sonae forces. The Rikusentai is a group of forty Samurai Rikusentai, intended for boarding operations and usually embarked on a Musashi class Assault Transport. Finally, the Jieitai provides planetary defence in the form of twelve Wakizashi point defence railguns, six Katana anti-ship railguns and twelve Tekkan, supported by a security force of two hundred Ashigaru and eighty Samurai. As of January 1st 2150, the WST comprises twelve Sonae, three Honjin, three Jieitai, four Kiba-tai and twelve Rikusentai.
