A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
The Seventh Fleet is a numbered fleet of the United States Navy. It is headquartered at U.S. Fleet Activities Yokosuka, in Yokosuka, Kanagawa Prefecture, Japan.

1 Main Circuit (1MC) is the term for the shipboard public address circuits on United States Navy and United States Coast Guard vessels. This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are (normally) able to hear it. It is used to put out general information to the ship's crew on a regular basis each day. The system consists of an amplifier-oscillator group which is located in the IC/gyro room, a microphone control station, portable microphones at each control station and loudspeakers located throughout the ship. Control stations for the 1MC announcing system are located at the pilot house, OOD stations on the quarterdecks, aft steering and Damage Control Central area.
USS Cyclops (AC-4) was the second of four Proteus-class colliers built for the United States Navy several years before World War I. Named after the Cyclops, a race of giants from Greek mythology, she was the second U.S. naval vessel to bear the name. The loss of the ship and 306 crew and passengers without a trace sometime after 4 March 1918 remains the single largest loss of life in the history of the United States Navy not directly involving combat.

Naval boarding action is an offensive tactic used in naval warfare to come up against an enemy watercraft and attack by inserting combatants aboard that vessel. The goal of boarding is to invade and overrun the enemy personnel on board in order to capture, sabotage, or destroy the enemy vessel. While boarding attacks were originally carried out by ordinary sailors who are proficient in hand-to-hand combat, larger warships often deploy specially trained and equipped regular troops such as marines and special forces as boarders. Boarding and close-quarters combat had been a primary means to conclude a naval battle since antiquity, until the early modern period when heavy naval artillery gained tactical primacy at sea.
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States.

It has the world's largest aircraft carrier fleet, with 11 in service, 1 undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of July 18, 2023.
Stanley Winfield "Swede" Vejtasa was a United States Navy career officer and World War II flying ace. During the Battle of the Santa Cruz Islands, he was credited with downing seven Japanese aircraft in one mission, becoming an "ace in a day".
A boarding net is a type of rope net used by ships during the Age of Sail to prevent boarding by hostile forces. Designed to hang from a ship's masts and encircle its deck, the boarding net could be deployed during battle or at night when a ship was at anchor in unknown or hostile waters. In the Royal Navy, boarding nets first gained widespread use in the 1790s.
