"In ordinary" as an English phrase.
In naval matters, vessels "in ordinary" (from the 17th century) are those out of service for repair or maintenance, a meaning coming over time to cover a reserve fleet or "mothballed" ships.
The term arose from the development of three separate financial estimates for Royal Navy expenditure; the "Ordinary" estimate which covered routine expenses such as the maintenance of dockyards and naval establishments, the "Sea Service" estimate which supported ships and crew at or capable of going to sea, and the estimate for "Extraordinary Repair" which met the cost of major rebuilding or refit. A ship that was no longer required for active service, or was too decrepit to remain at sea, would be transferred from the Sea Service to the Ordinary estimate, and would be left "in Ordinary" until returned to duty or broken up.
Ships could remain "in Ordinary" for lengthy periods, including for example HMS Royal William which spent 38 years "in Ordinary" between its launch in 1719 and first active service in 1757. Poorly maintained, they were susceptible to dry rot and were routinely crewed by pensioned or disabled sailors with little interest in a return to sea service. During the War of the Austrian Succession from 1739 to 1745, a review of ships "in Ordinary" revealed that at least half of their warrant officers were too old or sickly to serve outside their mothballed vessels. Improvements were made from 1752 when Admiral George Anson, the newly appointed First Lord of the Admiralty, initiated reforms of royal dockyards with the intention of maximising the number of vessels capable of being put to sea at any time. However, most of Anson's reforms were opposed by the Navy Board, which had direct responsibility for dockyard management and felt that Admiralty's interference was a rebuke to its authority.
