Squadron (naval) in the context of "East Asia Squadron"

The Battle of Sinop, or the Battle of Sinope, was a naval battle that took place on 30 November 1853 between Imperial Russia and the Ottoman Empire during the opening phase of the Crimean War (1853–1856). It took place at Sinop, a sea port on the southern shore of the Black Sea (the northern shore of Anatolian Turkey). A Russian squadron attacked and decisively defeated an Ottoman squadron anchored in Sinop's harbor. The Russian force consisted of six ships of the line, two frigates and three armed steamers, led by Admiral Pavel Nakhimov; the Ottoman defenders were seven frigates, three corvettes and two armed steamers, commanded by Vice Admiral Osman Pasha.

The Russian navy had recently adopted naval artillery that fired explosive shells, which gave them a decisive advantage in the battle. All the Ottoman frigates and corvettes were either sunk or forced to run aground to avoid destruction; only one steamer escaped. The Russians lost no ships. Nearly 3,000 Turks were killed when Nakhimov's forces fired on the town after the battle. The victory is commemorated in Russia as one of the Days of Military Honour.

A carrier strike group (CSG) is a type of carrier battle group of the United States Navy. It is an operational formation composed of roughly 7,500 personnel, usually an aircraft carrier, at least one cruiser, a destroyer squadron of at least two destroyers or frigates, and a carrier air wing of 65 to 70 aircraft. A carrier strike group also, on occasion, includes submarines, attached logistics ships and a supply ship. The carrier strike group commander operationally reports to the commander of the numbered fleet, who is operationally responsible for the area of waters in which the carrier strike group is operating.

Strike groups comprise a principal element of U.S. power projection capability; a single supercarrier holds enough firepower to rival the air forces of entire nations. Previously referred to as carrier battle groups (a term still used by other nations), they are often referred to by the carrier they are associated with (e.g., Enterprise Strike Group). As of March 2023 there are 11 carrier strike groups in the U.S. Navy.

The 5th Squadron (Russian: пятая эскадра, translit. pyataya eskadra, was a squadron of the Soviet Navy.

The squadron was first established in 1963–64 during the Cold War. The North Atlantic Treaty Organization (NATO) generally referred to it as the Soviet Mediterranean Fleet (Russian: Средиземноморский флот), as it was the primary adversary to the U.S. Navy's Sixth Fleet. Attached to the Russian Navy after the dissolution of the Soviet Union, the 5th Squadron was deactivated amid the downsizing of the Russian Armed Forces on 31 December 1992.

A squadron was historically a cavalry subunit, a company- or battalion-sized military formation. The term is still used to refer to modern cavalry units, and is also used by other arms and services (frequently aviation, also naval). In some countries, including Italy, the name of the battalion-level cavalry unit translates as "Squadron Group".
