Soviet NavyThe Soviet Navy was the naval warfare uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its sphere of influence in eastern Europe.
Gulf of FinlandThe Gulf of Finland (Soome laht; Suomenlahti; Фи́нский зали́в; Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk).

Winter WarThe Winter War was a war between the Soviet Union and Finland. The war began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union.
Occupation of the Baltic statesThe three independent Baltic countries – Estonia, Latvia, and Lithuania – were invaded and occupied in June 1940 by the Soviet Union, under the leadership of Stalin and auspices of the Molotov–Ribbentrop Pact that had been signed between Nazi Germany and the Soviet Union in August 1939, immediately before the outbreak of World War II. The three countries were then annexed into the Soviet Union (formally as "constituent republics") in August 1940. The United States and most other Western countries never recognised this incorporation, considering it illegal.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
