The Gulf of Aden (Arabic: خليج عدن; Somali: Gacanka Cadmeed) is a deepwater gulf of the Indian Ocean between Yemen to the north, the Arabian Sea to the east, Djibouti to the west, and the Guardafui Channel, the Socotra Archipelago, Puntland in Somalia and Somaliland to the south. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, and it connects with the Arabian Sea to the east. To the west, it narrows into the Gulf of Tadjoura in Djibouti. The Aden Ridge lies along the middle of the gulf, and tectonic activity at the ridge is causing the gulf to widen by about 15 mm (0.59 in) per year.

The ancient Greeks regarded the gulf as one of the most important parts of the "Erythraean Sea". It later came to be dominated by Muslims, as the area around the gulf converted to Islam. From the late 1960s onwards, there was an increased Soviet naval presence in the Gulf. The importance of the Gulf of Aden declined while the Suez Canal was closed, but it was revitalized when the canal was reopened in 1975, after being deepened and widened by the Egyptian government.

The Black Sea Fleet (Russian: Черноморский флот, romanized: Chernomorskiy flot) is the fleet of the Russian Navy in the Black Sea, the Sea of Azov and the Mediterranean Sea. The Black Sea Fleet, along with other Russian ground and air forces on the Crimean Peninsula, are subordinate to the Southern Military District of the Russian Armed Forces. The fleet traces its history to its founding by Prince Potemkin on 13 May 1783 as part of the Imperial Russian Navy. The Russian SFSR inherited the fleet in 1918; with the founding of the Soviet Union in 1922, it became part of the Soviet Navy. Following the collapse of the Soviet Union in 1991, the Black Sea Fleet was partitioned between the Russian Federation and Ukraine in 1997, with Russia receiving title to 82% of the vessels.

The Black Sea Fleet has its official primary headquarters and facilities at the Sevastopol Naval Base, Crimea, which Russia annexed from Ukraine in 2014. The rest of the fleet's facilities are based in locations on the Black Sea and the Sea of Azov, including Krasnodar Krai, Rostov Oblast and Crimea.

Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.

"Sonar" can refer to one of two types of technology: passive sonar means listening for the sound made by vessels; active sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

The Workers' and Peasants' Red Army, often referred by its shortened name as the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army (which embodied the main component of the Soviet Armed Forces alongside the Soviet Navy) was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army.

The Red Army provided the largest ground force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Japan. During its operations on the Eastern Front, it accounted for 75–80% of the casualties that the Wehrmacht and Waffen-SS suffered during the war, and ultimately captured the German capital, Berlin.

This list of Russian admirals includes the admirals of all ranks, serving in the Russian Imperial Navy, the Soviet Navy and the modern Russian Navy.

The Russian Navy is the naval arm of the Russian Armed Forces. It has existed in various forms since 1696. Its present iteration was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States (which had itself succeeded the Soviet Navy following the dissolution of the Soviet Union in late December 1991).

The Imperial Russian Navy was established by Peter the Great (Peter I) in October 1696. The symbols of the Russian Navy, the St. Andrew's ensign, and most of its traditions were established personally by Peter I.

The Armed Forces of the Union of Soviet Socialist Republics, also known as the Armed Forces of the Soviet Union, the Red Army (1918–1946) and the Soviet Army (1946–1991), were the armed forces of the Communist Party of the Soviet Union (CPSU), Russian Soviet Federative Socialist Republic (1917–1922) and the Soviet Union (1922–1991) from their beginnings in the Russian Civil War of 1917–1923 to the collapse of the Soviet Union in 1991. In May 1992, Russian president Boris Yeltsin issued decrees forming the Russian Armed Forces, which subsumed much of the Soviet Armed Forces. Multiple sections of the former Soviet Armed Forces in the other, smaller Soviet republics gradually came under those republics' control.

According to the all-union military service law of September 1925, the Soviet Armed Forces consisted of the Red Army, the Air Forces, the Navy, the State Political Directorate (OGPU), and the convoy guards. The OGPU was later made independent and amalgamated with the NKVD in 1934, and thus its Internal troops were under the joint management of the Defence and Interior Commissariats. In 1989, the Soviet Armed Forces consisted of the Strategic Rocket Forces, the Ground Forces, the Air Defence Forces, the Air Forces, and the Navy, listed in their official order of importance.

SMS M68 was a M1916 type minesweeper built for the Imperial German Navy during the First World War. She entered service on 6 October 1917, but was mined and sunk off Latvia on 29 October 1917. The ship was salvaged by Latvia and entered service with the Latvian Navy on 10 November 1921 under the name Virsaitis as its first vessel. She was taken over by the Soviet Navy in August 1940 when the Soviet Union occupied Latvia in August 1940, serving as T-297 and was sunk by a mine on 2 December 1941.

A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. It results from the event of shipwrecking, which may be intentional or unintentional. There were approximately three million shipwrecks worldwide as of January 1999, according to Angela Croome, a science writer and author who specialized in the history of underwater archaeology (an estimate rapidly endorsed by UNESCO and other organizations).When a ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships.
