AHTS VOS Hunter is an Anchor Handling Tug Supply (AHTS) built in 1979. Such vessels are mainly used for installation and towing work on offshore drilling platforms, as well as to provide rescue and support services in emergency situations.

The Titanic (RMS Titanic) is a luxury cruise ship owned by the British White Star Line. Construction began on March 31, 1909, at the Harland and Wolf shipyard, launched on May 31, 1911, and completed sea trials on April 2, 1912. However, on the night of April 14, the Titanic collided with an iceberg, causing the hull to break and eventually sink.

They were the main ships of the navies of Western powers from the mid-17th century to the mid-19th century, and they formed the core force of maritime combat at that time. Originating from large sailing ships, this three-or four-masted ship has a towering structure at the rear, usually carrying heavy artillery, and is distributed on two decks. It usually has three decks, equipped with bottom deck guns of 30 to 48 pounder shells, middle deck guns of about 24 pounder shells, and upper deck guns of 30 or more 12 pounder guns. As a symbol of sea power at that time, it was not until the emergence of steam-powered battleships that they gradually withdrew from the stage of history.

It is a modern warship that is specially designed to reduce radar cross-sectional area (RCS) and infrared radiation, making it difficult to detect by the enemy. The inclined hull design and superstructure are adopted to avoid being perpendicular to the water surface to reduce the reflection of radar waves. Antennas and electronics are often conformal in design and built into the hull to reduce radar signals. The use of absorbing materials and special coatings is also a common means of reducing RCS. The design not only considers radar stealth, but also includes reducing infrared signatures to reduce the possibility of being detected by enemy infrared detection equipment.

It is the third U.S. Navy Arleigh Burke-class guided missile destroyer and the first ship of this class to be deployed on the west coast. Named after the United States Navy hero John Paul Jones, he inherited his motto: "I wish to have nothing to do with any ship that does not gallop, for I intend to go down a dangerous path." Construction began on 8 August 1990 at Bath Steel Works, launched on 26 October 1991 and commissioned on 18 December 1993. It represents the modern combat effectiveness of the U.S. Navy and is equipped with the most advanced weapons, engineering and damage control systems.

It is a kind of ship that can operate underwater, with concealment and strong strike capability. It is mainly used for military purposes, such as anti-ship, anti-submarine operations, intelligence gathering, mine-making and special operations. There are two main categories: regular-powered submarines and nuclear-powered submarines. regular-powered submarines use diesel engines and battery packs, while nuclear-powered submarines use nuclear reactors as power sources, with the latter having almost unlimited underwater endurance. Key features include its streamlined design to reduce underwater drag and its ability to dive to a depth of hundreds of meters. Equipped with a variety of weapons, such as torpedoes, missiles and mines, capable of striking targets at sea and on land.

It is a large patrol ship built for the Russian Navy. It is mainly used to perform patrol, monitoring and protection tasks in open and closed waters. Construction began in February 2014, and as of December 2016, there are five ships under construction, the first of which joined the Russian Navy in December 2018. The design features include a modular design, with a length of 94 meters, a width of 14 meters, a height of 3.4 meters, a standard displacement of about 4,550 tons, and a capacity of 80 personnel. Equipped with a retractable hangar and helicopter deck, capable of supporting a 12-ton rescue helicopter. Enhance the operational capabilities of the Russian Navy in multiple fleets

The Kuznetsov aircraft carrier is the first ship of the Soviet/Russian third-generation 1143.5 aircraft carrier. It is the first true aircraft carrier of the Soviet Union and Russia, the world's first aircraft carrier to have both inclined and straight flight decks and ski jump flight decks, and the latest and only operational aircraft carrier of the Russian Navy. It is the main ship of the Russian Navy. The Kuznetsov aircraft carrier began construction on April 1, 1982 at the Nikolayev Shipyard in the Soviet Union. It was launched on December 4, 1985 and commissioned on January 21, 1991. The name was derived from the Soviet Navy Commander in Chief during World War II, Nikolai Gracimovi

During World War I, French submarines (Sous marin de la Premi è re Guerre mondiale) played an important role in naval battles. At the beginning of World War I, the French Navy had 62 submarines.
