Naval Shipbuilding and Systems

This register is the common source for every catalogued item and technical standard cited by the Kingsbury, Republic, Ward and Syndicate hull histories. Repeated physical items are represented once with the allowance quantity recorded against each class.

Catalogue rules

A production date records manufacture or approved procurement, not merely invention. Pipes, cable runs, fasteners and structural materials are represented by an accepted standard rather than by serial number. Food, cleaning materials, clothing and stationery are treated as naval supply products with a named supplier and procurement period.

Registry reconciliation

Registry	Classes	Commissioned hull entries, 1800–2026	2026 classes	2026 hulls
Kingsbury and Republic	72	1,649	17	384
Ward and Syndicate	67	1,774	12	366

The two registries contain 3,423 hull entries and 139 class dossiers. Each dossier carries 97 standard catalogue lines plus explicit production-block and major-refit deltas. Construction chronology, current-fleet totals, code resolution, manufacturer dates and the single-entry treatment of purchases, captures, conversions and transfers are checked when the register is rebuilt.

Security Landing mission variants

The Security Landing amphibious ships used ordinary 1940–1959 fleet equipment where no mission change was required. The following SECLAND identities denote installations whose drawings, quantities or purpose differed from the similarly numbered Security cruiser equipment. The suffix is part of the identity and prevents a cruiser system and an amphibious system from sharing one catalogue code.
