The Soviet Union remains more of an enigma than perhaps any other nation in human history. Its past is marked with stark contrasts, blending ancient European cultures with modern socialist ideals. Its actions have kept its rivals confused, with its true intentions never clear beyond doubt. Yet, if there is one unifying theme to its actions, it is the drive to expand Soviet power and the evolution of the communist system. In this effort, it has been undeniably successful. In the aftermath of the First Scinfaxi War, the Red Army occupied much of Eastern Europe and Central Asia, adding Bulgarian, Romanian, Chinese and Mongolian Socialist Republics into the Union. The power defined by the consolidation of these many disparate peoples, formed in the shadow of an alien menace, persists and thrives to this day.

Today, the Soviet Union is a vast nation that echoes its past on Earth. There are as many Soviet colonies as the next two largest nations combined: a matter of necessity when it came to establishing colonies capable of supporting its nearly 400 million citizens during the Second Scinfaxi War. The most prominent Soviet systems, Leningrad, Shaanxi, and Novosibirsk, are the equal of any of the grand capital worlds of the Orion Arm, yet many more remain underdeveloped backwaters. While high degrees of inefficiency and a large bureaucracy continue to plague Soviet developments, increasingly effective centralized state organs and seemingly endless resources have contributed to rapid industrial and economic development.  More spacecraft and machinery are produced in the Soviet Union than in any other nation, with Soviet exports particularly favored on the developing colonies of the Far Frontier for their reliability, ease of use, and low cost.

The Soviet Union has the Orion Arm’s largest population, with over 12 billion people. Its various component ethnic groups are nominally divided into 21 Soviet Republics, but continued emigration within the Soviet Union have blurred these lines considerably. The Russian people continue to dominate the Soviet Union with the Russian SSR foremost among the republics, but increasing Chinese influences can be found across the whole of the Union; the Chinese having surpassed the Ukrainian SSR as the second most populous republic in the late 2100s. Despite periodic attempts at Russification in its past, all citizens within the USSR are treated as equals before the law with discrimination of any kind widely abhorred as tool of the bourgeoisie and incompatible with Soviet values.

The Soviet Armed Forces are the largest in the Orion Arm, generally manned by conscripts but with a core of veterans and professionals. The Soviet Navy, traditionally marginalized in favor of the Red Army has grown in priority as the Soviet Union seeks to project its power across the whole of the Orion Arm. The development of the Rodina, the largest class of ship ever built, signifies a change in Soviet military strategy and vastly increases its capabilities.

The Soviet Union maintains somewhat icy relations with the Democratic Federation, yet several trade agreements exist with its members, particularly with the French Republic. The Empire of Japan is especially hostile towards the Soviet Union with periodic skirmishes, and trade only taking place rarely through intermediaries in the Greater Asia Co-Prosperity Sphere. Relations with many smaller nations including the Islamic Arab Republic, Federative Republic of Endi Martell, the New Canaan Republic and the Vega Confederation are generally much more favorable, and include significant arms deals and economic assistance treaties. The Greater German Reich remains the primary rival of the Soviet Union in military and territorial matters, a position made apparent in news feeds across human space when the two nations entered into a period of undeclared war over their respective border systems and the Soviet ally of Vega.
