The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

Greenock is a town and administrative centre in the Inverclyde council area in Scotland, United Kingdom and a former burgh within the historic county of Renfrewshire, located in the west central Lowlands of Scotland.

Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship.

Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself.

The Royal New Zealand Navy is the maritime arm of the New Zealand Defence Force. The fleet currently consists of nine ships. The Navy had its origins in the Naval Defence Act 1913, and the subsequent purchase of the cruiser HMS Philomel, which by 1921 had been moored in Auckland as a training ship. A slow buildup occurred during the Interwar period, and then perhaps the infant Navy's finest hour occurred soon after the beginning of World War II when HMS Achilles fought alongside two other Royal Navy cruisers at the Battle of the River Plate in December 1939.

Auckland is a large metropolitan city in the North Island of New Zealand. The most populous urban area in the country and the fifth largest city in Oceania, Auckland has an urban population of about 1,440,300. It is located in the greater Auckland Region—the area governed by Auckland Council—which includes outlying rural areas and the islands of the Hauraki Gulf, and which has a total population of 1,695,200. While Europeans continue to make up the plurality of Auckland's population, the city became multicultural and cosmopolitan in the late-20th century, with Asians accounting for 31% of the city's population in 2018. Auckland has the eighth largest proportion of foreign born residents in the world, with 41% of its residents born overseas. With its large population of Pasifika New Zealanders, the city is also home to the biggest ethnic Polynesian population in the world. The Māori-language name for Auckland is Tāmaki Makaurau, meaning "Tāmaki desired by many", in reference to the desirability of its natural resources and geography.

Sydney is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about 70 km (43.5 mi) towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Nicknames of the city include the 'Emerald City' and the 'Harbour City'.

Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China, is a city and special administrative region of China on the eastern Pearl River Delta in South China. With 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world. Hong Kong is also a major global financial centre and one of the most developed cities in the world.

The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.

The ship's cat has been a common feature on many trading, exploration, and naval ships dating to ancient times. Cats have been carried on ships for many reasons, most importantly to control rodents. Vermin aboard a ship can cause damage to ropes, woodwork, and more recently, electrical wiring. In addition, rodents threaten ships' stores, devour crews' foodstuff, and can cause economic damage to ships' cargo, such as grain. They are also a source of disease, which is dangerous for ships that are at sea for long periods of time. Rat fleas are carriers of plague, and rats on ships were believed to be a primary vector of the Black Death.

HMS Black Prince was a Dido-class light cruiser of the Royal Navy, of the Bellona subgroup. The cruiser was commissioned in 1943, and served during World War II on the Arctic convoys, during the Normandy landings, and as part of the British Pacific Fleet. In 1946, the cruiser was loaned to the Royal New Zealand Navy, becoming HMNZS Black Prince. The cruiser was docked for modernisation in 1947, but in April, her sailors walked off the ship as part of a series of mutinies in the RNZN. The shortage of manpower resulting from these mutinies meant that the modernisation had to be cancelled, and Black Prince was placed in reserve until 1953. She returned to service after refitting with simplified secondary armament with a single quad "pom pom" in Q position and eight Mk3 40mm Bofors guns. The ship was decommissioned again two years later, and returned to the Royal Navy in 1961. Black Prince did not re-enter service, and was towed from Auckland to Osaka for scrapping in 1962.

A military discharge is given when a member of the armed forces is released from their obligation to serve. Each country's military has different types of discharge. They are generally based on whether the persons completed their training and then fully and satisfactorily completed their term of service. Other types of discharge are based on factors such as the quality of their service, whether their service had to be ended prematurely due to humanitarian or medical reasons, whether they had been found to have drug or alcohol dependency issues and whether they were complying with treatment and counseling, and whether they had demerits or punishments for infractions or were convicted of any crimes. These factors affect whether they will be asked or allowed to re-enlist and whether they qualify for benefits after their discharge.
