Ship decommissioning in the context of "USS Port Royal (CG-73)"

HMS Essex was one of 10 Monmouth-class armoured cruisers built for the Royal Navy in the first decade of the 20th century. Upon completion in 1904 she was assigned to the 2nd Cruiser Squadron of the Channel Fleet. The ship was placed in reserve in March 1906 and recommissioned in 1909 for service with the 4th Cruiser Squadron on the North America and West Indies Station. In 1912, Essex returned home and was assigned to the Training Squadron of the Home Fleet. After a refit the following year, she rejoined the 4th Cruiser Squadron in early 1914.

After the beginning of World War I in August, the ship captured a German merchantman the following month. Essex spent most of the first half of the war in the Atlantic Ocean, escorting convoys and searching for German commerce raiders. The ship captured another German merchantman in mid-1916 and was reduced to second-line roles such as depot ship and accommodation ship a few months later. She was paid off in 1919 and sold for scrap two years later.

USS John F. Kennedy (hull number CV-67) (formerly CVA-67), the only ship of her class, was an aircraft carrier, formerly of the United States Navy. Considered a supercarrier, she was a variant of the Kitty Hawk class, and the last conventionally-powered carrier built for the Navy, as all carriers since have had nuclear propulsion. Commissioned in 1968, the ship was named after John F. Kennedy, the 35th president of the United States. John F. Kennedy was originally designated a CVA, for fixed-wing attack carrier, however the designation was changed to CV, for fleet carrier.

After nearly 40 years of service, John F. Kennedy was decommissioned on 1 August 2007. She was berthed at the NAVSEA Inactive Ships On-site Maintenance facility in Philadelphia, formerly the Philadelphia Naval Shipyard, and, until late 2017, was available for donation as a museum and memorial to a qualified organization. In late 2017, the Navy revoked her "donation hold" status and designated her for dismantling.

The Kingston class consists of 12 coastal defence vessels operated by the Royal Canadian Navy. The class is the name for the Maritime Coastal Defence Vessel Project (MCDV). These multi-role vessels were built and launched from the mid- to late-1990s and are crewed by a combination of Naval Reserve and Regular Force personnel. The main missions of the vessels are reservist training, coastal patrol, minesweeping, law enforcement, pollution surveillance and search and rescue. The multi-purpose nature of the vessels led to their mixed construction between commercial and naval standards. The Kingston class is split between the east and west coasts of Canada and regularly deploy overseas to West Africa, Europe, Central America and the Caribbean.

In July 2025, the Royal Canadian Navy announced that the Kingston class will begin to be paid off and retired starting in late 2025, with an intended replacement in the planning stage.
