PQ 17 was the code name for an Allied Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by German forces on 1 July, after which it was shadowed continuously and attacked. The First Sea Lord Admiral Dudley Pound, acting on information that German surface units, including the German battleship Tirpitz, were moving to intercept, ordered the covering force built around the Allied battleships HMS Duke of York and the USS Washington away from the convoy and told the convoy to scatter. Because of vacillation by Oberkommando der Wehrmacht, the Tirpitz raid never materialised. The convoy was the first large joint Anglo-American naval operation under British command; in Churchill's view this encouraged a more careful approach to fleet movements.
The 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 period between the two countries. The influence of the Soviet Navy played a large role in the events involving the Cold War (1945-1991), as the majority of conflicts centred around the American-led NATO alliance in western Europe or power projection to maintain its sphere of influence in eastern Europe.
USS Fairfax (DD-93) was a Wickes-class destroyer in the United States Navy during World War I, later transferred for World War II service first to the Royal Navy as HMS Richmond (G88), a Town-class destroyer, and then to the Soviet Navy as Zhivuchiy.
USS Crowninshield (DD–134) was a Wickes-class destroyer in the United States Navy between World War I and World War II. She was named for Benjamin Williams Crowninshield. In World War II she was transferred to the Royal Navy where she was named HMS Chelsea, and subsequently to the Soviet Navy where she was named Derzkiy.
A submarine chaser or subchaser is a small and fast naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II.
The Japan Maritime Self-Defense Force, also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships and 346 aircraft and consists of approximately 45,800 personnel. Its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. It also participates in UN-led peacekeeping operations (PKOs) and Maritime Interdiction Operations (MIOs).
The Baltic Sea Campaigns were conducted by Axis and Allied naval forces in the Baltic Sea, its coastal regions, and the Gulf of Finland during World War II. After early fighting between Polish and German forces, the main combatants were Germany and Finland, opposed by the Soviet Union. Sweden's navy and merchant fleet played important roles, and the British Royal Navy planned Operation Catherine for the control of the Baltic Sea and its exit choke point into the North Sea.
Asashio, meaning "morning tide" in Japanese, may refer to:
The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's Hull classification symbol system. The Royal Navy and some European and Commonwealth navies use a somewhat analogous system of Pennant numbers.
The Black Sea Campaigns were the operations of the Axis and Soviet naval forces in the Black Sea and its coastal regions during World War II between 1941 and 1944, including in support of the land forces.
There were several ships of the Polish Navy bearing the name of ORP Ślązak :
Operation FB took place as part of the Arctic Convoys of World War II. The operation consisted of independent sailings by unescorted merchant ships between Iceland and Murmansk. In late 1942, Allies had taken the offensive against Germany but the dispatch of supplies to the USSR by convoy via the Arctic route was suspended, due to the demands of the Mediterranean campaign. Convoy PQ 19 was cancelled because the Home Fleet diverted ships to the Mediterranean for Operation Torch which would have had to be postponed for three weeks had ships been provided for PQ 19.
Submarine warfare in the Black Sea in World War II during 1942 involved engagements between primarily submarines of the Soviet Black Sea Fleet attacking Axis merchantmen defended by Romanian and German naval warships. These engagements were a part of the Black Sea campaigns between Axis and Soviet naval forces.

SS Dekabrist was a Russian steamship, built in 1903 and immediately converted to an armed merchant cruiser. She served in the Russo-Japanese War, World War I, the Russian Civil War, and World War II. She was sunk in 1942.
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
